In a world that prizes certainty, hot takes and quick success, what happens when we celebrate the power of not knowing in this in TikTok, scientist and storyteller Harini Bhatt shares how she built a popular YouTube channel today I learned science where curiosity and not credentials is what drives discovery. From ancient brains that turn to glass to the origins of life itself, she reminds us that science isn't just for scientists, it's for all of us. Willing to ask why? And marvel at the answers.

Raise your hand if you don't know what this is. That is a human brain turned to glass during the Mount Vesuvius eruption. But it gets weirder. Only this man's brain turned to glass, not his other organs, leaving scientists baffled about how ash clouds could create the precise temperature conditions to forge glass from living tissue. If you didn't know what this was, then you're exactly where you should be. Because this talk is about the power of not knowing. Here's why this matters now more than ever. We live in a culture that's absolutely obsessed with having the right answer. Immediately, social media rewards confident hot takes over curious questions. Everyone is supposed to be an expert in everything all the time. Get something remotely wrong, canceled. It's exhausting. But I think I found another way. When I started my channel today, I learned in two years, over 2 million people followed. Not for expert opinions or hot takes, but for something simpler. Shared curiosity. Which is ironic because I used to be the complete opposite. Before this, I was a recovering know it all. Actually, a wannabe know it all who was failing spectacularly at it. During my doctor at ucsf, I was obsessed with certainty and having the right answer before anyone even asked the question. When Covid hit, I started posting science videos as a creative outlet. But even then I constrained myself. Only post about things, you know, Harini. So I stuck rigidly to pharmacy topics, my supposed area of expertise. And let me tell you, it was real riveting stuff. Then I went to Mexico. I was standing in front of the Theodocan pyramids in the blazing heat when I realized something profound. I had no idea what I was looking at. Who built this? Why here? Where did they go? Instead of feeling embarrassed that I didn't know, I felt alive. Every carving was a mystery that made my brain tingle in ways that pharmaceutical calculations never did. That night, I couldn't stop researching. Not to become an expert, but to feed my curiosity. I made a video about Tetoacan, posted it, and went to sleep. Expecting my usual 3 likes from my parents and my husband. I woke to 40,000 new followers. My first viral video had nothing to do with my eight years of higher education. It was about me, a human being, nerding out over ancient architecture and then sharing the incredible work of the archaeologists who spent lifetimes piecing together the mysteries of Teotihuacan. Here's what hit People weren't following me because I was an expert. They were following me because I was curious. And curiosity is contagious because here is the paradox of our time. We have infinite access to information, but also infinite misinformation. Conspiracy theories get more clicks than peer reviewed studies. Confident nonsense spreads faster than careful science. In that chaos, championing credible voices and making that work accessible seemed to unlock something in people. Because after that, my comments exploded with tilt. Today I learned in that moment, my mission became clear. Take the most rigorous, mind blowing research and make it so captivating that someone scrolling at 2am stops and goes wait.

What?

Because science is for everyone. Not dumbed down but translated with the excitement it deserves. I changed my channel name that night and didn't look back. Here's where my curiosity has taken me. There is a 72 year old geologist who rewrote the origins of life before gta Vian Manuel Garcia Ruiz could have retired, but instead he chose to recreate the famous 1952 primordial soup experiment. The one that showed us how life began on Earth. But with one tiny change. Instead of using a glass container like the original, he used Teflon. The result? Nothing. Turns out the glass, specifically the silica, was key. When he added silica back in, he didn't just get amino acids, he got all five DNA building blocks and protocells, the self organizing structures that came right before actual life. Translation Life on Earth may have started hundreds of millions of years earlier than we thought. This should be breaking the Internet, but Most people will never hear about it. That is the gap I'm trying to bridge. Because science isn't just for scientists. When researchers discover how life began, or unlock how ancient brains turned to glass, these are ultimately human stories about curiosity, perseverance, asking brave questions. And everyone deserves to feel that electrifying. I can't believe we just learned that moment like this. For the first time in 2025, we got to witness a human embryo implanting into uterine like tissue in real time. From this, we learn. Embryos aggressively burrow, possibly following uterine contractions like GPS signals. This process is actually physically painful. The countless women who felt a sharp twinge and wondered if they'd imagined it, they didn't. Science just caught up to what their bodies already knew. We finally answered one of human development's biggest black boxes while validating millions of women's experiences in the process. After doing this for a few years, here's what I've learned. People don't make discoveries because they already know things. They make discoveries because they get obsessed with the stuff they don't know. And learning isn't linear. It's a beautiful, endless loop. When I shared my Teotihuacan obsession, I was inviting 40,000 other people to be curious with me and showing them science can be as captivating as any Netflix series. See, my doctorate taught me how to read studies and think critically. But my channel taught me that everyone deserves access to that knowledge. So here's my challenge for Find your tetrahuacan. Find the thing that lights you up from the inside. Not because you understand it, but because you don't. Maybe it's quantum physics. Maybe it's how sourdough starter is basically a pet you can eat whatever makes you feel like that kid that asked why over and over until your parents wanted to scream. When I first started dating my husband, he called me 20 questions bringing that energy to the table. TLDR stayed gloriously, unapologetically curious. All right, that's it for me. I gotta go research how the real city of Atlanta is buried beneath our feet.

TED Talks Daily – “The thrill of not knowing all the answers” | Harini Bhatt
Date: November 20, 2025
Host: TED (Elise Hu introduces)
Speaker: Harini Bhatt
In this thought-provoking TED Talk, scientist and storyteller Harini Bhatt makes a compelling case for celebrating curiosity over expertise. Drawing on her experiences building the “Today I Learned Science” YouTube channel, she reveals how embracing what we don’t know can unlock wonder, accessibility, and meaningful discovery in science—and in our daily lives. Bhatt’s talk is both a critique of a knowledge-obsessed culture and an energizing call to rekindle our inner question-askers.
[04:01] Harini Bhatt opens by showing an unusual scientific artifact: a human brain, turned to glass by Mount Vesuvius. Only this man's brain, not his other organs, was vitrified—a mystery that scientists are still trying to solve.
She frames the talk: “If you didn’t know what this was, then you’re exactly where you should be. Because this talk is about the power of not knowing.”
Bhatt critiques the modern obsession with certainty and expertise, especially amplified by social media’s reward mechanisms for “confident hot takes.”
“We live in a culture that's absolutely obsessed with having the right answer. Immediately, social media rewards confident hot takes over curious questions. Everyone is supposed to be an expert in everything all the time. Get something remotely wrong, canceled.” (Harini Bhatt, 04:25)
“That night, I couldn't stop researching. Not to become an expert, but to feed my curiosity.... I woke to 40,000 new followers. My first viral video had nothing to do with my eight years of higher education. It was about me, a human being, nerding out over ancient architecture...” (Harini Bhatt, 05:40)
“[This is] the paradox of our time. We have infinite access to information, but also infinite misinformation. Conspiracy theories get more clicks than peer reviewed studies.” (Harini Bhatt, 06:52)
“Translation: Life on Earth may have started hundreds of millions of years earlier than we thought. This should be breaking the Internet, but most people will never hear about it. That is the gap I'm trying to bridge.” (Harini Bhatt, 08:48)
“Embryos aggressively burrow, possibly following uterine contractions like GPS signals... The countless women who felt a sharp twinge and wondered if they'd imagined it—they didn't. Science just caught up to what their bodies already knew.” (Harini Bhatt, 10:34)
“Find your Teotihuacan. Find the thing that lights you up from the inside. Not because you understand it, but because you don’t... TLDR, stay gloriously, unapologetically curious.” (Harini Bhatt, 11:33)

Bhatt’s impassioned talk encourages listeners to let go of the fear of “not knowing,” to be curious, and to recognize science as a shared human adventure. In an era saturated with misinformation and a thirst for certainty, she insists, “Stay gloriously, unapologetically curious.”
