Neil Degrasse Tyson
At any given moment. It's the next round of science mysteries. What is dark matter? What is dark energy? It is 95% of what is driving the universe. What was around before the big bang? Is there a multiverse? I lose sleep wondering, are we smart enough to ever actually figure out the universe?
Mayim Bialik
World famous astrophysicist Neil Degrasse Tyson is here to help us understand the universe by figuring out where we came from, why we're here, and what our destiny might be beyond the stars. Are there aliens?
Neil Degrasse Tyson
Genetically, we're within one 1.5% identical DNA to a chimpanzee. Imagine a life form who has 1 1/2% DNA in that vector. Beyond us.
Mayim Bialik
Wow.
Neil Degrasse Tyson
What would we look like to them? Earth could be a literal aquarium terrarium that they constructed for their own amusement. I'm all in on smart aliens being out there somewhere. And if they find us and they want to make us their pet, that's the best we might be able to hope for.
Mayim Bialik
Are we living in a simulation?
Neil Degrasse Tyson
It's hard to argue against it. As the area of our knowledge grows, so too does the perimeter of our ignorance. But of anything humans have ever invented, science may be uniquely capable of giving us access to our understanding of our place in the universe. Universe. And secure pathways into our future.
Mayim Bialik
Hi, I'm Imbialik.
Jonathan Cohen
And I'm Jonathan Cohen.
Mayim Bialik
And welcome to our breakdown. This is an earth shattering episode.
Jonathan Cohen
It's also very, very funny.
Mayim Bialik
It's a universe expanding episode.
Jonathan Cohen
We cannot wait to tell you who we're having on today.
Mayim Bialik
Usually in our intros we do like a. What happened before the Big bang? What happens when you die? Are we living in a simulation? Are there aliens? Can we time travel? Guess what? We've got the man who's going to answer all of these things. Jonathan. Who's our guest today?
Jonathan Cohen
Today we are speaking to Neil Degrasse Tyson.
Mayim Bialik
He is an astrophysicist, as you know, and the director of the Hayden Planetarium at the American Museum of natural history since 1996. He's the author of 19 books. He's an incredibly, incredibly talented and gifted science communicator. Also was on two episodes of Big Bang Theory which we're gonna talk about before we get into. Can we time travel? Are there aliens? Are aliens watching us? Are we living in a simulation? What happens after we die? How does he explain near death experiences? Is there a God? We cover everything possible with Neil Degrasse Tyson. In this episode we do wanna mention just visiting this planet. Further scientific adventures of Merlin from Omnisia I think that's how you pronounce was first published in 1998, but there is a new edition that just came out in 2025. It's really, really awesome. It's the. Dr. Tyson's character Merlin is answering more questions. Also, Cosmos Confidential, Neil and Bill's excellent bromance, is an incredible audio project with William Shatner that is out now, so check that out as well. And Merlin's tour of the universe, revised and updated for the 21st century, came out in 2024. So his books are incredible, wonderful gifts. Also, like, this is the kind of book like I want to give to my kids. Like, these are all the questions. Tackle them.
Jonathan Cohen
So we're very excited to have Neil here in person.
Mayim Bialik
Without further ado, Dr. Neil DeGrasse Tyson. Welcome to the Breakdown. Break it down.
Neil Degrasse Tyson
Well, thanks. Thanks for having me. This is my first time on the show, I think.
Jonathan Cohen
So we've been trying.
Neil Degrasse Tyson
Oh, my God.
Mayim Bialik
We have wanted to speak to you for a very long time.
Neil Degrasse Tyson
Cause I've been around, you know. Cause you never call, you didn't write, you know. Cause you've been on my podcast.
Mayim Bialik
Okay, so this is. Yes. So that was maybe 10 years ago.
Neil Degrasse Tyson
Okay.
Mayim Bialik
Which is a distant memory and I
Neil Degrasse Tyson
was deeply honored and I wanted to do right by it.
Mayim Bialik
Tell us about your Big Bang Theory crossover. Was I there?
Neil Degrasse Tyson
Not the first time, but the second time. But you were not in any of the scenes that I was involved in.
Mayim Bialik
My memory is used for Blossom scripts, Big Bang Theory scripts, and music songs that you haven't heard in 40 years. I remember the lyrics, but I literally, I spent a night with my grandmother in a hotel in Florida and I don't remember that. And I don't remember if we crossed paths on Big Bang Theory, but there you go.
Neil Degrasse Tyson
It can happen where you don't remember. Don't be upset by that. It's called age. So my first cameo was. I think it was season three.
Mayim Bialik
Perhaps I came in at the end of season three.
Neil Degrasse Tyson
Yeah, yeah, this was. And I had a run in with Sheldon on whether Pluto should be a planet because I was just pilloried by eight year old third graders who had just memorized the Educated Mother. That's nine pizzas. Right. And so I have these. I have hate mail from elementary school children, like, scrawled in crayons.
Jonathan Cohen
That's the worst kind of hate.
Neil Degrasse Tyson
It's the worst kind of hate because you're so. It breaks your heart. And dear Dr. Tyson, now I don't have a favorite planet because you Took away my. Here's a picture of it. Put it back into the.
Jonathan Cohen
I have no hopes and dreams anymore.
Neil Degrasse Tyson
So while I was implicated in the demotion of Pluto, I was really just an accessory. I mean, the data came in. And in New York City, we were the most visible exponent of the demotion of Pluto because we were opening a brand new exhibit and we just took Pluto, plucked it from the ranks of planets.
Mayim Bialik
So rude.
Neil Degrasse Tyson
It had it coming. We plucked it from the ranks of planets and grouped it with the other dirty ice balls in the outer solar system where it belongs.
Jonathan Cohen
Dirty ice balls.
Mayim Bialik
Just the language that you use. It's insulting.
Neil Degrasse Tyson
It's accurate. So that was a man of your
Mayim Bialik
academic stature to refer to Pluto as such.
Neil Degrasse Tyson
So I just want to make it clear I'm not an actor. So even playing myself, I needed tips from, you know, the director and the. And so it was very helpful. You know, I would. I would later host Cosmos, which gave me a little more facetime to a camera and even script time. How to read a script as though it's just coming out of you fresh that you take that for granted. But oh, my gosh, to do that.
Mayim Bialik
Right?
Neil Degrasse Tyson
And so they wanted to. For Cosmos, you didn't ask this, but I'm going there. They wanted to get me a voice coach. And I said, voice coach? I know how to speak. What do you mean, voice? You know, welcome to the universe. What do you mean, voice coach? These are people who teach you accents, you know, on the screen. I don't need a voice coach.
Mayim Bialik
What did they want?
Neil Degrasse Tyson
So they brought in the voice coach, and it was like one of the most amazing moments I've ever had.
Mayim Bialik
What did they do? Well, did you used to speak with an Irish accent?
Neil Degrasse Tyson
They made me what I am today. No, no, no. It was. It was how to read a script. And here was the transition moment for me. I walked through a portal through a proscenium. It was. Here is a list of planets in order from the sun. Okay, here it is on script. Okay, give it to me. And so I say, okay, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto at the time. Okay. We're still kind of considering it. All right, now, how would you say that if you were not reading it? Okay. Even though it's still there.
Mayim Bialik
Yeah.
Neil Degrasse Tyson
And so here's how I would now do it. I would say Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Now, that's way more sort of off the top of your head. And that bit completely transformed me in my ability to read scripts against something you would take for granted because you did it professionally.
Mayim Bialik
This episode is behind the Actor's studio with Neil DeGrasse.
Neil Degrasse Tyson
Exactly. How to turn Neil into a slightly better cameo actor than anyone.
Mayim Bialik
You do have a very melodious voice. Like, you do have a very beautiful voice.
Neil Degrasse Tyson
I don't hear myself, you know, when I'm out in the world and I wear a hat. And the COVID mask helps greatly to tamp down the rest of the.
Mayim Bialik
There's no more Covid. Or is that what you're here to tell us?
Neil Degrasse Tyson
No, but I do that, and it tamps down the recognition factor. But your voices. So then I speak, and then people just turn around, and then. So I have to, like, do that and not speak if I want to
Mayim Bialik
go totally incognito, recognize me from my voice. I think if you have any unusual voice, that's not, you know, kind of the timber of most people.
Jonathan Cohen
Now do the planets method style. Like, they are all about to go in different directions and the universe is ending.
Neil Degrasse Tyson
Oh, wow. Mercury, Venus, Earth, Mars, Jupiter, Saturn. I need my motivation. Thank you.
Jonathan Cohen
That coach really did work.
Neil Degrasse Tyson
So the second time.
Mayim Bialik
I was just gonna say the second
Neil Degrasse Tyson
time was in the final season.
Mayim Bialik
And, yeah, everyone remembers that.
Neil Degrasse Tyson
Yeah, yeah. That's when you got your Nobel Prize.
Mayim Bialik
Oh, right.
Neil Degrasse Tyson
What do you mean, oh? Just an afterthought.
Mayim Bialik
I was not on drugs.
Neil Degrasse Tyson
Okay.
Mayim Bialik
I just don't hold.
Neil Degrasse Tyson
I remember whether or not you do. Okay, So I. So that explains why I'll come up to actors where they had some really impactful line that they uttered in a movie, and I'll just recite it back to them, and they'll look at me like, what? What are you gonna say? And so I had to come to realize that when you perform, it's a performance in the moment and you keep moving on.
Mayim Bialik
Correct.
Neil Degrasse Tyson
It doesn't sit with you the way it might sit with the people who you touched.
Mayim Bialik
Correct.
Neil Degrasse Tyson
With your handiwork.
Mayim Bialik
Right.
Neil Degrasse Tyson
So. And that one, it was a fun storyline where Raj was asked by the local news to comment on a comet that was coming through. There was some astronomical event, and he thought he'd be cute and say, oh, was Neil degrasse Tyson not available? And the host of the music anchor just ignored that and then continued with the question. So that freaks him out. Said, maybe I was not the first choice. And then he starts making fun of me professionally and socially. And then you have. Who among you were watching this on television saying, raj, pull up, pull up. Raj, Raj. And so then I Catch wind of this. And then they script me in a conversation with him from my office, rebuilt my office. They took some pictures in my office and remade everything. And so I'm there and I call him up and he's in a car. And I say, raj, this is Neil Degrasse Tyson. Oh, oh, oh, what about this Twitter dust up that we're in? Because it happened over social media. And I say, I'm gonna be at the. What's the bookstore in Pasadena? There's a bookstore there? I'm gonna be at Frohman's, come there and tell that to my face. And he says, oh, no, I'm busy. I can't make it. I'm sorry. So it was a very tense kind of thing. But the funnest script line, which was invented in the moment, not by me, I can't take credit for this, was I'm going through a list of people who I'm calling out for their conduct on social media. And then so we hang up. And I said, that was satisfying. Now who else needs a degrasse whooping?
Mayim Bialik
Degrasse whoopin.
Neil Degrasse Tyson
A degrasse whoopin. And then I call Bill Nye, right? And so I said, bill, this is Neil. We gotta talk. And then quickly hangs up. And that's my only. That was my only presence.
Mayim Bialik
So.
Jonathan Cohen

Make 2026 the year you finally start sleeping again. This episode is sponsored by Wandering Jews, an open door media brand.
Mayim Bialik
If you've ever found yourself feeling like you have more questions than answers, you're in good company. The Jewish people have been like that for thousands of years. Wandering Jews with Michal and Noam is a podcast where two of today's most dynamic Jewish voices, Michal Bittone and Noam Weissman, dig into the biggest questions about life through a Jewish lens. It's the kind of conversation where you'll laugh, learn something new, and probably shout in disagreement at least once. Michal and Noam tackle the tough topics like anti Semitism in America, what happens after we die, and the future of religion with guests like Bret Stephens, Michael Rock Rappaport and Sarah Hurwitz. And this past month, in honor of Jewish American Heritage Month, they've been celebrating some of the Jewish lives and institutions that have shaped American life, from food to music and comedy. Thoughtful, joyful, and always honest. That's Wondering Jews with Michal and Noam a production of Unpacked. Find it on your favorite podcast app or on YouTube and make sure to hit subscribe.

Neil Degrasse Tyson
I was delighted that my people have representation in the acting world. And it was, I was, you know, how many cop dramas can you show? How many, you know, emergency room shows? How many of these is worth one geek show? Okay. And I think Chuck and Bill. Bill, Chuck, Glory, Bill Prady. They saw that there was low hanging fruit that probably would have been rejected in a dozen of other idea proposals to the gatekeepers of what gets aired and what doesn't and say, here it is, there'll be scientists and no one will know what they're talking about and there'll be jokes and everyone will laugh. It's like, right, okay. And I'm so glad that it wasn't just a mildly successful Show. It was one of the most successful shows ever. And, you know, Gilgan's island went three seasons. Shall I remind us of this? Okay. The original Star Trek went three seasons.
Mayim Bialik
Wow.
Neil Degrasse Tyson
And if you look at some of the episodes in that third season, you were reminded why it only went three seasons and you guys went eight, nine seasons.
Mayim Bialik
No, we went 12.
Neil Degrasse Tyson
12, was it, we would say.
Mayim Bialik
We were like. We got graduation rings at the end. We were like 12th graders.
Neil Degrasse Tyson
12th graders. So just congratulations. I haven't, you know, seen you since then.
Mayim Bialik
Well, I mean, I. I was just happy to be along for the ride. But, you know, having you on and Stephen Hawking, I mean, we had some incredible people on William Shatner as well. William Shatner and Kareem Abdul Jabbar. My gosh, that's right. I mean, we also kind of like most of the Star Trek world, which is like a Bill Prady, you know, kind of thing.
Neil Degrasse Tyson
One last thing, if I may. Just because as I'm, you know, fanboying on the show, that show took turns that, for any other show, might have been jumping the shark. Okay. You know, there is your main character interested in a woman who's out of his league, and there's a tension there.
Mayim Bialik
You don't have to talk about me like that. I'm right here. Oh, you're talking about Penny. I get it.
Neil Degrasse Tyson
And so there's sexual tension there. There's awkwardness, and that propels scripting.
Mayim Bialik
Sure.
Neil Degrasse Tyson
You're gonna consummate that and have them get married. You don't do that in a sitcom. But they did. You guys did it. And everybody ended up married. And it was so. That, I think, was heroic to get that to work in a sitcom and not have it pull you back.
Mayim Bialik
Yeah. I mean, I remember when I joined, you know, people were very, very protective over the Sheldon character in particular. And a lot of people felt like he shouldn't have a girlfriend. Like, it's gonna draw away. But I think the writers found a really nice way to tie it in.
Neil Degrasse Tyson
I hope the chance of jumping the shark by doing that.
Mayim Bialik
Yeah.
Neil Degrasse Tyson
And you told me you probably won't remember this. Okay. You told me your instructions how to act. Your role was to be a girl
Mayim Bialik
Sheldon instead of a boy Sheldon Cooper. That's right.
Neil Degrasse Tyson
Yeah. If you then that, then you become. Then you're not interfering with him, you are supporting him.
Mayim Bialik
Correct.
Neil Degrasse Tyson
In that way. And that worked brilliantly.
Mayim Bialik
Now I have to be a female Neil DeGrasse Tyson today.
Neil Degrasse Tyson
Well, give me some of your voice, Mars. No, no, Mars.
Mayim Bialik
I Would pronounce it Uranus also, because I am a third grader.
Neil Degrasse Tyson
No, Uranus, if you're third grade, yes.
Jonathan Cohen
That's the one question to wrap this segment, which is out of the scientists and colleagues that you have now. Who do you want to call and give the business to?
Mayim Bialik
Who needs a degrasse?
Neil Degrasse Tyson
No, I would not. I don't run around thinking that way. I'll do it for a scripted sitcom.
Jonathan Cohen
You don't have to publicly share it,
Neil Degrasse Tyson
but there's got to be no point. I'll tell you secretly now, but don't tell anybody.
Mayim Bialik
Well, maybe we'll get to it in all of the questions that we have. So in the time that we have with you, you know, obviously, you do this, you speak, you educate you.
Neil Degrasse Tyson
I try to bring the universe down to earth.
Mayim Bialik
Correct. You try to bring the universe down to earth. And what we wanted to do is, you know, we've talked a lot, especially in the last year or so, about sort of this intersection between science and spirituality. What are some of the things that are fantastical? What's the science behind them? So we're just kind of gonna go through some topics and see what strikes your fancy.
Neil Degrasse Tyson
Bring it on.
Mayim Bialik
Sound good?
Jonathan Cohen
Beautiful.
Neil Degrasse Tyson
Bring it on.
Mayim Bialik
And there's obviously, I'm going to preface
Neil Degrasse Tyson
that by saying not 10, 15 years ago, I would enter a conversation about spirituality or religion in a kind of a distance, discounted way. And then I had to mature out of that. And what I mean by that is I'm an educator. And people come to me with sincere, honest thoughts, questions, concerns about their lives, how they were raised, what they care about, what they value. And I realized I owed them a more nuanced, more thoughtful reply than just, is there evidence for it? Just chuck it.
Mayim Bialik
Sure.
Neil Degrasse Tyson
So I then spent quite a bit of time reading. Is literature the right word? No. Reading tracts, religious tracts all around the world. You know, Hindu, you know, I have a copy of the Torah at home, for example.
Mayim Bialik
It's very popular.
Neil Degrasse Tyson
I have. I have every. I have every pamphlet that was left at my door by the Jehovah's Witnesses. They also do something slightly different, you know, and so I have a shelf of that. And so I just. I have Joseph Smith's account for the Mormons. And so that way when someone comes to me, I have some sensitivity to their wiring.
Mayim Bialik
We weren't gonna start here, but since you kind of opened the door to that, I'd love this as a sort of framework because one of the things that I'm interested in is how Much different traditions, and I include academic traditions in that. How much Our function as humans on this planet is to try and figure out where we came from, why we're here and where we're going. And to me, science is another religion of sorts, right? It's a. It's a set of beliefs, it's a set of theories, It's a set of ways to think and approach things. So many of the religious traditions are trying to figure out the answers to these things. Some have some scientific merit. What is your general perspective, right, on trying to frame those three questions? Where did we come from? Why are we here, and where are we going?
Neil Degrasse Tyson
Before the methods and tools of science were available to us, the whole world was a mystery. You know, why is there a storm? Oh, Poseidon has risen up. There's a lightning bolt that struck. You know, even go back to the early 19th century, even when Ben Franklin is learning about lightning and how it operates and what attracts it, and he invents the lightning rod. And now you put that on your building and it protects you from getting destroyed. But before then, churches would get hit by lightning bolts. Okay? And if it was your church and not my church, there it was, you're preaching the wrong gospel there that God let you know. And so divinity of all stripes, be it monotheistic or polytheistic, was the account that people conjured to explain that which they had no control over. Science rises up and one by one, these are put in the record books. Okay? No one is blaming Poseidon or who's the Roman version of that? Neptune. No one is blamed with the Trident. So that has been the trend, and that trend continues to this day. And so I have been quoted occasionally, accurately, with the following statement, if to you, God is where science has yet to tread, okay? Because I would say, you know, we have all evidence points to the big bang. Someone would ask, but what was around before the big bang? I said, I don't know. Got top people working. Something had to be there. Was it God? Okay? The urge to put God or some divine power in a place where science has yet to tread is huge. And we've been at. People have been doing that for thousands of years.
Mayim Bialik
Literally.
Neil Degrasse Tyson
Yeah. Yes. Okay. Newton did it. Ptolemy did it. I'll give you. Let's go back to AD150, Ptolemy. He pioneered the. The geocentric understanding of the world. Earth in the middle. Everybody's going around Earth. You had to put planets on epicycles because planets occasionally go to the left and then they slow down, stop, and then they Go to the right again. They invented a word for that. They called it retrograde. All right, so how do you explain all of that? You have these epicycles. So there you are. You know what he said in the margin of his greatest work, where he lays all this out? He hand wrote, I know that we are mortal by nature and ephemeral, but when I trace at my pleasure the windings to and fro of the heavenly bodies, I no longer touch earth with my feet. I stand in the presence of Zeus himself and take my fill of ambrosia. He's feeling it. Okay, now that was obviously not the Judeo Christian God. That was the Greek God. He was a Greek polymath. But that's him appealing to divine influence on something he doesn't really yet understand. And even Isaac Newton would do this. So this doesn't escape the most brilliant minds there ever was. And it continues basically to this day, but it manifests slightly differently today. Now people go around. So the philosophers call this the God of the gaps, okay? And so my reply to that was, if to you, God is where science has yet to tread, then God is an ever receding pocket of scientific ignorance. And because that's an if statement, it's just sort of fundamentally true. Because it's an if statement. What people have done, especially the atheist community, which is trying hard to fully claim me, but I keep some distance.
Mayim Bialik
They're very like religious fanatics sometimes they'll
Neil Degrasse Tyson
try to grab anything I say. What they did was. They left off the first part of that quote. And they have their T shirts. They have it say, God is an ever receding pocket of Neil DeGrasse Tyson. Yes, those words came out of my mouth, but it followed an if statement. That matters. I'm not just declaring what God is. No, I'm saying if statements. If God to you is this, then this has to follow. So I don't see science as equivalent to other attempts to understand the world because it does not appeal to a divinity, to any divine forces, whereas basically every other religion does. So that distinguishes it, I think, from the rest. Now fast forward to modern times. You know what happens? People go see the pyramids, and how did they do it? I don't know. Aliens must have helped. Okay, so you just watch how often aliens show up in people's account. So I, I said, maybe we're entering an era of aliens of the gaps, but that doesn't have the. The alliteration site. So I invented a new phrase, aliens of our ignorance. So you have people today who there's something. Lights in the sky, moving. I don't know what it is. Must be aliens. So aliens are supplanting the role that God had played in our ignorance in modern times. But science pushes on. And yes, there are theories. The word theory has been misused. I don't want to blame people because. But let me officially say what a theory is, okay? You can't run around and say, I have a theory, that whatever. No, you have a hypothesis. Einstein had a theory. You have an hypothesis. If you have an idea that's not tested, it's a hypothesis. Once it's tested and verified and reverified. And reverified. And it organizes things that happen in the world in a coherent way, makes predictions that you can verify, that's a theory. There was a day when we called them laws. But we're a little more humble going forward.
Mayim Bialik
Darwin's theory of evolution is one that people.
Neil Degrasse Tyson
Yeah, no, no, it's fine. We still call it that. People want to think just because and for understandable reasons that when you use the word theory, well, we're still just making stuff up and we don't know. I'm saying quantum theory has never been shown to be experimentally wrong, but we still call it quantum theory. We call it Einstein's theory of relativity. We don't call it Einstein's law of relativity. It's just a 20th century recognition that an idea that may be right in every way tested, there might be tests on the edge of it that show where it fails and that there might be a deeper understanding awaiting us. That's what's going on now. That's what happened between Isaac Newton and Einstein. Isaac Newton has the laws of motion, laws of gravity, and it's working. We went to the moon on Newton's laws, right? And then we find out, wait a minute. If the gravity is really strong or if you're moving really fast, Newton's laws don't work anymore. We're getting the wrong answer. What's going on? Einstein says, I got the answer. It's relativity. And relativity gets you in those extreme places, and it gets the right answer. What happens if you put low speeds and low gravity into Einstein's equations? They become Newton's equations. So it's not like we're Newton's out, Einstein's in. Newton is embedded within a deeper understanding. And so that's where theory carries us into the future.
Mayim Bialik
I wonder, is there a place where science has gone too far in pushing out some of the mystical, some of the inexplicable have we gone too far?
Neil Degrasse Tyson
Am I biased when I say science can never go too far? It is conceived and constructed to give we feeble humans a deeper understanding of the world in which we live so that we're not running away from mysterious. One of the titles of Carl Sagan's book was A Demon Haunted World, subtitled importantly, Science as a candle in the Dark. Without the science, we're wandering in the dark, running away from ghosts. And can I tell you what I did with my kids? Should I admit this? I don't know when they were really little. Okay. So my wife has a PhD in mathematical physics. So we have two kids who are being raised with science literate parents. Nerds. Okay. Nerds. Okay. And you know, do we live in a time when someone will accuse you of being a nerd? Say nerd. And you know what my reply is? Thanks for the compliment.
Mayim Bialik
Yep.
Neil Degrasse Tyson
That's all I say. So I wanted that. I didn't want them to be afraid of ghosts, okay. Because I'm not yet convinced that ghosts are real or have ever been real. So they were really young. And so I said, I'm going to put you in this closet, this dark closet and close the door, okay? And then, then I'm going to get a monster to try to break into the closet. So of course it's me.
Mayim Bialik
And they know it's parenting by Neil DeGrasse Tyson.
Neil Degrasse Tyson
So I close the closet and I go and they start laughing and laughing and laughing. And so they've never been afraid of turning a corner of the dark or of a haunted house. It takes some of the fun out of haunted houses because you're just not buying it.
Mayim Bialik
You know, I'm scared of everything because my parents got into the closet with me and were like, what if a
Neil Degrasse Tyson
monster comes and the monster was still there? So let me get, let me give the other half of that. Yes, There are mysteries today that people enjoy or it gives them a sense of. What do we say? A sense of not knowing everything. And that's kind of important to some people. They don't want science to know everything. What they don't know is at any given moment, there is no end of science mysteries that are still there, not still there. It's the next round of science Mysteries. It's not. Are the ghosts in the closet? No. Is it. What is dark matter? What is dark energy? How did we go from organic molecules to self replicating life? Earth seemed to have no trouble doing that. We still don't know how to do that. In the lab. We have top people working on it. What was around before the Big Bang? Is there a multiverse? Will we ever make a wormhole? These are mysteries and they're less grand mysteries that still exist in all the sciences. So my issue here is, yeah, I'm getting rid of some of the magisterial mysteries that you grew up with, but I'm replacing them with others because science has tread there and has come up with answers where we're moved on to the next question.
Jonathan Cohen
We are all fascinated with the edges that science is exploring and are along for that ride.
Neil Degrasse Tyson
And the edges are always there. And here's my favorite comment on that. As the area of our knowledge grows, so too does the perimeter of our ignorance.
Mayim Bialik
Say it again.
Neil Degrasse Tyson
As the area of our knowledge grows, so too does the perimeter of our ignorance. Because that's the boundary between what we know and don't know. So for me, science is like a forever thing.

Jonathan Cohen
I love this. And if I give voice to some of the people who have said, wait a second. Science is sometimes so dogmatic and so assured of what they know that they have missed the mark. For example, when medical doctors said the mind and body are totally separate and the mind never impacts the body. And now we're showing more and more that those two things are far from the truth and actually have led medicine quite astray. Then they're trying to plead to the scientists to sort of stay open and curious and, you know, challenge continually what we know and push those edges.
Mayim Bialik
For example, you know, people like Gabor Mate, right, have introduced this notion that we used to think we know why autoimmunity happens, we know why cancer happens, right? We know why diabetes happens.
Jonathan Cohen
And we know some, we know a good chunk of the story.
Mayim Bialik
But the interplay between, let's say, stress the environment, right? And our physiology reveals that there is a much more elaborate combination of things that make up what, as scientists, we try and understand, but there are many elements that are harder to put our finger on, correct?
Neil Degrasse Tyson
So a couple things first, and I've said this on social media just to put it out there, physics and astrophysics and understanding the universe is way easier than understanding the human mind, body and soul. Okay? So let me just make that clear. The human mind and its interplay with itself and your body. Oh, my gosh. It's part of the reason why neuroscience as a field is so young relative to physics and astronomy. They say astronomy is the second oldest profession. So we've had the benefit of millennia of brilliant thinkers contributing to physics, astronomy, engineering. You know, the pyramids were built, you know, 5,000 years ago. So our advances in human. Part of what resisted that was the sanctity of the human body. You don't just cut open the body just to explore, especially not the human mind. And correct me if I'm wrong, because this is your business. A lot of what we learned about the functioning of the brain came from brain injuries to people. And what was left over after this part of the brain got damaged. So this is not the brain in a Petri disk. This is waiting around for a brain injury to see what you'll learn on the next emergency room visit. So I just want to make that point clear. Second, there is no end of examples you can give, such as the one just presented, where there's a prevailing truth, let's call it, that would later be shown to be false. I will say without hesitation that if you go back to that time and look at the research going on, I guarantee you whatever was the thing that was ultimately shown to be wrong was not experimentally verified. It was. I think this is true. It's probably true. I did a few things on my own. What do you think? Yeah, it makes sense. Let's declare it. And so it's the experimental verification that makes it true. And it's very hard to experiment on the human body for the reasons I
Mayim Bialik
stated and the human mind.
Neil Degrasse Tyson
So that's why all. And especially the human mind, that's why your best examples of this are going to come from the field of medicine, okay. Where doctors are in denial that, let me operate on this cadaver, let me deliver your baby. And did you wash your hands? No. Why do I have to wash my hands? The doctor's hands. Okay. There's no research supporting that. And so it's kind of a caricature of science to say, and by the way, there's. Well, Earth was flat and then it's not flat. So, excuse me, Earth being flat, that knowledge and expectation predated the existence of telescopes. Okay. And it predated the tradition of science to test your idea. It was. Yeah, it kind of looks flat. It's probably flat. Oh, it looks like. And plus, the Bible doesn't deny this. We're in the center of the universe. Everything goes around us. Our vocabulary still preserves a geocentric universe. I don't say to you, Mayim, I don't ask you, what time tomorrow does Earth rotate such that our sight line to the sun appears over the horizon? No, we say, what time does the sunrise. That's a geocentric vocabulary word. So it's what the world looks like. What science tells us is the world isn't always what it looks like and it isn't always what it seems. And so that's my reply to you, but just to give a shout out to the medical community, you know what? Our life expectancy was in cavemen, okay? Half of everyone born wasn't suffering from menopause. That's another way to say it. Everyone was fertile their whole lives.
Mayim Bialik
We did our best work before 20
Neil Degrasse Tyson
so, so half of everyone born was dead by the age of 30. Half. Okay, caveman says 10,000, 20,000 years ago. Fast forward to 1850. 1840. Half of in the world was dead before they turned 35. And everyone in that time was eating organic and the water ran pure.
Mayim Bialik
That's not bad.
Neil Degrasse Tyson
It's true. That is true. Does not have to be fair. Okay, they all ate organic. And so what happens in the late 1800s?
Mayim Bialik
Didn't know to wash their hands before a doctor put his hands inside their body.
Neil Degrasse Tyson
At the second half of the 19th century, germ theory matures. We have Pasteur who develops this. We bring the microscope to our physiological needs. And between 1840 and today, we have doubled your life expectancy. So with all of your comments, well, the mind actually is affecting the body. And the doctors were clueless. They had their head up their ass, whatever else was happening. That increase in life expectancy is not because of how people are eating. It's because of medicine. It is because of science. And my path into this description came from a New Yorker comic, okay. By the artist Gregory. I don't know if it's first or last name, but it says Gregory signs it. There are two cavemen sitting across from the fire. And one says to another, you know, they say this, they say, our water runs pure. Our game is free game. And everyone is eating healthy, eating organic. But no one lives past 30. And so science matters here. And it is so fundamentally infused in our lives, it is so easy to take it for granted. That's my reply. Oh, one other thing. I know it's kind of related. You didn't say it, but I'm gonna bring it up. There are people who say science will never understand love. For example, if not love, then something else. Put in your favorite thing there. Then I say to such a person, is that because you don't want science to ever understand love. And I realize they want science to have boundaries. And as a scientist, I don't see that as a real thing. And I can imagine an experiment where science then fully understands love. I can make one up. For example, we find out that you look at a painting and you feel great affection for it. Not sexual love, but really you love the painting.
Mayim Bialik
It's none of your business what I feel when I look at a painting.
Neil Degrasse Tyson
In English, we don't distinguish between just loving something because you like it a lot, and sensual, romantic love. So you look at a painting, and then you look at the same painting and you feel the same way. And we do some brain scans in the same part of the brain is being activated in both of you. And we do this experiment. 100 people. Or if it's not the same pain, it's just something that they have affection for. Okay, we found the love center of the brain. Okay, so now let's go into your brain. And there's something that you don't care, you don't have any feelings about. And I tickle it while you're looking at it. And then you talk about it and say, I love this. I never realized it before. And you do this automatically after I tickle the brain. Once we know the brain center and how we can control it. That's science. Understanding love. Now we move on to the next question. That's an example. Whether that'll ever happen, I don't know. But it's a completely plausible.
Mayim Bialik
Well, and I think also, I mean, love. It's a good example. I think that there are absolutely certain components that we can understand. The sort of symphony that creates attraction and connection. Right. Is a combination of a variety of systems. Right.
Neil Degrasse Tyson
Then it's more than one part of the brain. Perhaps.
Mayim Bialik
Thank you. We appreciate. It's very generous of you as an astrophysicist.
Neil Degrasse Tyson
No, no, I simplified the case. Like consider a spherical cow. Correct. I simplified it to a plausible experiment.
Mayim Bialik
Correct.
Neil Degrasse Tyson
Perhaps not yet conducted. Correct. That would answer for me what science would have to say about love.
Mayim Bialik
Correct.
Neil Degrasse Tyson
By the way, I'm just delighted to be in your company.
Mayim Bialik
Well, we are delighted to have you here.
Neil Degrasse Tyson
No, really, we're having a great time because you just. Thank you for having me.
Mayim Bialik
Thank you.
Neil Degrasse Tyson
I'm delighted to be in your company too, but a little less so than.
Jonathan Cohen
I get that all the time.
Mayim Bialik
Ok, let's. Let's talk about simulation theory. Oh, sure, I knew of the phrase, but it was not until we had Rizwan Verk on to talk about simulation theory that I really understood what we're talking about. Meaning. I had heard people say, like, we're living in a simulation. And I was kind of like, I don't want to talk to you. But once I read the book, I understood the structure of what this conversation is. So I know you're asked a lot of things that don't matter, and I don't know where simulation theory falls.
Neil Degrasse Tyson
No, as an educator, I care about what makes people curious.
Mayim Bialik
Okay.
Neil Degrasse Tyson
Simulation theories at the top 10 in the list.
Mayim Bialik
Okay, great.
Neil Degrasse Tyson
So, God, Alien simulation theory, in that order.
Mayim Bialik
Those are literally our bedtime stories.
Jonathan Cohen
Black holes and the multiverse.
Neil Degrasse Tyson
They come later than God. Aliens and simulation Theory.
Mayim Bialik
Let's dive into simulation theory.
Neil Degrasse Tyson
Bring it on.
Mayim Bialik
I'm curious when you first kind of became aware of this notion of simulation theory. And I'm curious what your take on it is. Does it seem to fit what doesn't fit? What works for you about it?
Neil Degrasse Tyson
It's hard to argue against it. So we don't like it. Nobody likes realizing you're in a simulation. But when I go through the arguments, it's hard to argue my. I can give you my best argument against it.
Mayim Bialik
Well, I want your best support for it.
Neil Degrasse Tyson
Oh, sure, sure, sure.
Mayim Bialik
No, so, and then I want.
Neil Degrasse Tyson
Yeah, yeah, it's. I'm not claiming that I'm in a camp that is cheering on. I'm just. As someone who thinks about this, I want to share with you those thoughts. We have ever growing computing power available to us and we create worlds on our computer for. For our own amusement. And let's take something simply like Mario, okay? Look at some primitive version of the Mario game, and there's Mario walking around and he picks up coins, I think, and he jumps. And you can ask the question, does Mario have free will?
Mayim Bialik
Sure.
Neil Degrasse Tyson
Is Mario self aware?
Mayim Bialik
Right.
Neil Degrasse Tyson
When you look at the code that makes Mario, it's pretty clear that Mario doesn't. Marriage is following lines of instructions. All right? Well, that's limited by our computing power. We can put more and more nuance into that character as computing power continues to grow. And imagine a future of quantum computing where it's thousands, millions, even billions of times more computing. Call it phenomena computing.
Mayim Bialik
Sophistications, Features.
Neil Degrasse Tyson
Yeah, sophistications that can be put into the simulation.
Mayim Bialik
Like, can you insert free will into the.
Neil Degrasse Tyson
So you can put so many options that the question about whether your choice is free will doesn't even matter anymore because the number of options you had available to you essentially mimic having free will.
Mayim Bialik
This is the Matrix, okay?
Neil Degrasse Tyson
Except in the Matrix, you're living in your own mind and your body still exists.
Mayim Bialik
So does he knock something over? Right. Because.
Neil Degrasse Tyson
Oh, you mean at the beginning when he's with the, with the oracle. Yeah. How would he have known if that. If it was the case? So that, that depends on whether your timeline is already understood.
Mayim Bialik
Sure.
Neil Degrasse Tyson
And you just access your timeline. Can you go back in time before it? Right. All right, so now imagine a future where we create a world where Mario believes Mario has free will. Because the options available to Mario at any node. Do I go through the door, up, down, Do I just stay here? Do I bake a cake? Do I order pizza? You know, Do I take an Uber? It's large enough to be indistinguishable from. It's approaching infinity and the limit as N goes to infinity. Your choices mimic free will. Now let's make 8 billion people and create a world. I'm old enough to remember the video game SimCity. I'm a city kid. So you are mayor of the city, and they can vote you out of office if you don't make them happy in their opinion polls. And you got to move money. There's only limited. Do you raise taxes? That way you can improve the schools, but the people won't vote for you if you raise taxes. This is an entire dynamic. And you get into it and you say, oh, my gosh, I am mayor and I am doing this.
Mayim Bialik
I do matter.
Neil Degrasse Tyson
And one feature that I thought was a little contrived, but later on I said, no, it was real. Every now and then, Godzilla walks through your city, and I said, this is stupid. And then I said, no, this is real.
Mayim Bialik
It's Donald Trump.
Neil Degrasse Tyson
And so ask me, why is that
Mayim Bialik
real, Neil, Why is it real?
Neil Degrasse Tyson
Because there was September 11th. No, it's not literally Godzilla, but it's something nobody ordered.
Jonathan Cohen
It's a black squan event.
Neil Degrasse Tyson
Okay? It's something happens that wreaks havoc on your city, and now you have to solve what just happened. And so I take that that was now 20 years ago when I was playing this game. Today, imagine there are 8 billion people in a world that they think is a real world, and they're all just having. And then they evolve because they programmed in evolution. Not only biological evolution, but cultural evolution and scientific. And they invent computers. They invent computers in that world and they get bored and they want to create a game, and so they advance to quantum computing, and they have a fractal. So there it goes. And it's then simulations all the way down. And now close your eyes. Throw a dart. Which universe are you in? The first one that programmed the next one, which is real, or the countless others, and you're going to land in the countless others. So I don't have a good argument against that. I have an argument that softens it, but I don't have a good argument that will remove that from the table. Can I give you my softening argument?
Mayim Bialik
Sure.
Neil Degrasse Tyson
Okay. We do not yet have the computing power to create that world.
Mayim Bialik
Sure.
Neil Degrasse Tyson
So we can't be any of the ones that have already created another world that takes out the entire middle of this cascade. Meaning we are either the first real universe that hasn't gotten there yet. Or we're the last universe, right, that's simulated that has yet to evolve to that state.
Jonathan Cohen
If you have to pick one, which are you.
Neil Degrasse Tyson
Well now that's 50. 50. I want to be real. You know, like, like Pinocchio. I want to be.
Mayim Bialik
We're gonna hit pause on our conversation with Neil DeGrasse Tyson. There is so much more coming in part two of our conversation with him. We're gonna talk about non human intelligence. We're gonna talk about near death experiences, psychedelics, meditation also and the nonlinear nature of time.
Jonathan Cohen
We also touch on the akashic records and mysteries that he wants. More information about. Dark matter, dark energy, what happened before the big bang. And are humans smart enough to figure out more about the universe?

Host: Mayim Bialik and Jonathan Cohen
Guest: Neil deGrasse Tyson
In this thought-provoking and wide-ranging episode, world-renowned astrophysicist and science communicator Neil deGrasse Tyson joins Mayim Bialik and Jonathan Cohen to dive into humanity’s largest questions. Covering everything from the origins of the universe, the intersection of science and spirituality, simulation theory, the search for aliens, and the persistent mysteries at the frontiers of knowledge, this episode explores whether humanity is intellectually equipped to grasp the true nature of reality, and how science can guide us forward in an age filled with uncertainty and wonder. Tyson brings his signature curiosity, humor, and depth to questions about consciousness, the possibility that we are living in a simulation, and why the “God of the gaps” keeps moving as science explains more of the unknown.
Opening Thoughts (00:00):
Tyson sets the stage with the burning questions at the edges of science: "What is dark matter? What is dark energy? ... I lose sleep wondering, are we smart enough to ever actually figure out the universe?"
[Neil deGrasse Tyson, 00:00]
Mayim introduces the episode’s theme: understanding the universe—where we came from, why we're here, and what could be beyond the stars, including the search for aliens and considerations of humanity’s ultimate destiny.
Are We Smart Enough?
Tyson muses that the more we know, the more we realize how much we don’t know: "As the area of our knowledge grows, so too does the perimeter of our ignorance."
[Neil deGrasse Tyson, 33:44]
(Big Bang Theory discussion – light, humorous, personal insight)
Tyson recounts his cameos on "The Big Bang Theory" and reflects on the cultural significance of scientists being represented authentically on TV:
"How many cop dramas can you show? ... It's worth one geek show, okay? And I think Chuck and Bill ... saw that there was low hanging fruit ... and I'm so glad that it wasn't just a mildly successful show. It was one of the most successful shows ever."
[Neil deGrasse Tyson, 15:12]
Tyson shares entertaining anecdotes about hate mail from children for Pluto’s demotion, and the process (voice coaching included!) of shifting from academic presentations to acting and public science communication.
Mayim frames a key theme:
“To me, science is another religion of sorts... it’s a set of beliefs, a set of theories, a way to think and approach things.”
[Mayim Bialik, 21:15]
Tyson responds, emphasizing how science's methodology distinguishes it:
"I don't see science as equivalent to other attempts to understand the world because it does not appeal to a divinity, to any divine forces, whereas basically every other religion does. So that distinguishes it, I think, from the rest."
[Neil deGrasse Tyson, 26:10]
He discusses the historic pattern of invoking divinity to explain the unknown, observing:
“If to you, God is where science has yet to tread, then God is an ever-receding pocket of scientific ignorance.”
[Neil deGrasse Tyson, 26:10]
Tyson notes his journey from dismissing spiritual/religious questions to embracing more nuanced, empathetic responses as an educator, reading religious texts to better understand others’ wiring.
[19:52]
Bialik pushes the discussion: Has science gone too far in banishing the mystical? Tyson counters that science is constantly generating new mysteries as it solves old ones but replaces “magisterial mysteries” with ever-deeper questions.
[30:06–33:23]
Tyson highlights that a persistent “edge” remains as science advances:
"At any given moment, the next round of science mysteries..."
[Neil deGrasse Tyson, 32:02]
From dark matter to the origins of life, Tyson underscores that being unsettled with not knowing is part of the human experience, yet science arms us with ever-brighter “candles in the dark.”
[30:06]
Jonathan brings up “dogmatism” in science—especially in medicine, where once-common beliefs (like mind and body being separate) have now been overturned.
Tyson acknowledges science’s occasional missteps, especially in fields where controlled experiments are difficult (medicine, psychology), noting neuroscience’s relative youth:
“Physics and astrophysics...is way easier than understanding the human mind, body, and soul.”
[Neil deGrasse Tyson, 37:10]
He reminds listeners that science’s great leap in increasing human lifespan (from 30 in the Stone Age to far longer today) is due to medicine grounded in scientific method—not merely lifestyle or diet:
“That increase in life expectancy is not because of how people are eating, it’s because of medicine. It is because of science.”
[Neil deGrasse Tyson, 42:20]
Challenging the idea that some things (like love) are beyond science, Tyson imagines a future where love’s “center” in the brain could be measured and manipulated:
“Once we know the brain center and how we can control it, that’s science understanding love. Now we move on to the next question.”
[Neil deGrasse Tyson, 45:27]
Bialik pushes for a nuanced view, suggesting attraction is a “symphony” of systems—Tyson agrees his example is a simplification, but illustrates a plausible path for science.
Tyson summarizes the simulation argument:
"When I go through the arguments, it’s hard to argue... My best support for it: the number of options you had available ... essentially mimic having free will… Now let’s make 8 billion people and create a world.”
[Neil deGrasse Tyson, 47:25–51:03]
Tyson counters that we don’t (yet) have the computing power to simulate such a universe—so we are either the first (real), or the last simulation to not yet create its own.
Tyson’s personal stance:
"I want to be real. You know, like, like Pinocchio. I want to be."
[Neil deGrasse Tyson, 53:02]
On the ever-present scientific mystery:
"As the area of our knowledge grows, so too does the perimeter of our ignorance."
[Neil deGrasse Tyson, 33:44]
On historic explanations:
"The urge to put God or some divine power in a place where science has yet to tread is huge. And people have been doing that for thousands of years."
[Neil deGrasse Tyson, 24:06]
On Pluto and public hatred:
"I have hate mail from elementary school children, like, scrawled in crayons."
[Neil deGrasse Tyson, 05:14]
On life expectancy:
"All of your comments, well, the mind actually is affecting the body...That increase in life expectancy is not because of how people are eating, it’s because of medicine. It is because of science."
[Neil deGrasse Tyson, 42:20]
On simulation theory:
"It’s hard to argue against it. We don’t like realizing you’re in a simulation, but… the arguments are compelling."
[Neil deGrasse Tyson, 47:25]

The conversation pauses with a teaser for part two, promising discussion of non-human intelligence, near-death experiences, psychedelics, meditation, time’s nonlinear nature, and humanity’s ongoing quest to push the boundary of the knowable.
This episode is a must-listen for anyone fascinated by the boundary between science and spirituality, the philosophy of knowledge, and just how far science can—and should—go in probing the deepest mysteries of human existence.
