Podcast Summary: "Are We Smart Enough to Understand the Universe? Could Humans be Alien Pets? Neil deGrasse Tyson on Simulation Theory, Why Your God is too Small and How Science Will Guide Us into the Future"
Mayim Bialik's Breakdown – February 3, 2026
Host: Mayim Bialik
Guest: Dr. Neil deGrasse Tyson
Co-Host: Jonathan Cohen
Overview
In this illuminating, humorous, and wide-ranging episode, astrophysicist and acclaimed science communicator Dr. Neil deGrasse Tyson joins Mayim Bialik and Jonathan Cohen for a breakdown of humanity’s deepest cosmic questions. Topics span the nature of scientific discovery, the limits of human understanding, the interplay between science and spirituality, simulation theory, and whether humans might be the pets of alien intelligence. Tyson’s wit, warmth, and curiosity animate the discussion, making high-level concepts accessible and deeply engaging.
Key Discussion Points & Insights
1. Curiosity and Cosmic Mysteries
-
Opening Thoughts: Tyson expresses existential wonder:
"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?"
(00:00) -
Our Place in the Universe: Tyson muses on how insignificant humans are on the genetic scale and imagines advanced alien life:
"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. ... 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."
(00:32)
2. Intersecting Science, Religion, and Human Experience (23:00–38:00)
-
Evolution of Tyson’s Approach: Tyson describes his maturation from dismissive skepticism to nuanced exploration with those seeking meaning:
"...I realized I owed them a more nuanced, more thoughtful reply than just, is there evidence for it? Just chuck it."
(23:04) -
Science vs. Spiritual Explanation: Explains humanity’s historic tendency to ascribe supernatural causes to the unknown, later replaced by scientific understanding:
"Divinity of all stripes...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..."
(25:21) -
God of the Gaps:
"...if to you, God is where science has yet to tread, then God is an ever receding pocket of scientific ignorance."
(27:18) -
New Gaps Filled by Aliens:
"So I said, maybe we're entering an era of aliens of the gaps...So you have people today who there's something...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."
(29:22) -
On Scientific Theories:
"If you have an idea that's not tested, it's a hypothesis. Once it's tested and verified and reverified...that's a theory."
(31:35)
3. The Nature and Power of Scientific Inquiry (33:18–36:51)
-
Science as Endless Inquiry: Tyson extols the never-ending frontier of science and its humble openness to the unknown:
"As the area of our knowledge grows, so too does the perimeter of our ignorance."
(36:41, repeated at 36:56) -
Carl Sagan Reference:
"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."
(33:18) -
Parenting & Banishing Fear: Humorously describes how he and his wife (a mathematical physicist) raised their children without fear of the dark or monsters:
"...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."
(34:51)
4. Critiques of Science—Limits and Openness (38:35–47:10)
-
Caution Against Scientific Dogma: Mayim notes the failings of earlier medical science that denied mind-body connection.
Tyson acknowledges medicine’s historic resistance and the challenges of experimental verification in human brains and bodies:"...physics and astrophysics and understanding the universe is way easier than understanding the human mind, body and soul. ... It's part of the reason why neuroscience as a field is so young relative to physics and astronomy."
(39:50) -
Science Improves Life Despite Missteps:
"...That increase in life expectancy is not because of how people are eating. It's because of medicine. It is because of science."
(45:00) -
Can Science Ever Explain Love?
Tyson offers a hypothetical experiment in which neuroscience could map and even trigger love in the brain, dismissing boundaries around scientific understanding:"I can imagine an experiment where science then fully understands love…That's science. Understanding love. Now we move on to the next question.”
(47:10)
5. Simulation Theory and Free Will (49:52–55:53)
-
Tyson’s View on Simulation Theory:
"It's hard to argue against it...We have ever growing computing power available to us and we create worlds on our computer for our own amusements...Imagine a future of quantum computing where it's thousands, millions, even billions of times more computing..."
(50:05) -
Free Will in a Simulated World:
"...the number of options you had available to you essentially mimic having free will."
(51:44) -
SimCity and Higher Level Simulations:
"And you get into it and you say, oh, my gosh, I am mayor and I am doing this...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. ... No, this is real...Because there was September 11th. No, it's not literally Godzilla, but it's something nobody ordered."
(53:32) -
Recursive Simulated Universes:
"Imagine there are 8 billion people in a world that they think is a real world...and 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...now you 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 gonna land in the countless others. So I don't have a good argument against that."
(54:00) -
Possible Reprieve:
"We do not yet have the computing power to create that world. 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."
(55:11)
Notable Quotes & Memorable Moments

"The urge to put God or some divine power in a place where science has yet to tread is huge."
(26:00, Tyson) -
On Science & Humility:
"There was a day when we called them laws, but we're a little more humble going forward.”
(31:35, Tyson) -
On Perpetual Mystery:
"As the area of our knowledge grows, so too does the perimeter of our ignorance."
(36:56, Tyson; “Say it again!” prompts Jonathan Cohen.) -

(34:18, Tyson) -
On Love as a Scientific Target:
"I can make one up. For example, we find out that you look at a painting and you feel great affection for it. ... And we do some brain scans and the same part of the brain is being activated in both of you. ... That's science. Understanding love. Now we move on to the next question."
(47:10, Tyson) -
On Humanity as Possible Alien Pets:
"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."
