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

Episode Overview

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.

Key Discussion Points & Insights

1. The Power—and Joy—of Not Knowing

• [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)

2. Her Journey: From ‘Know-It-All’ to Curious Creator

• Originally a “wannabe know-it-all,” Bhatt recalls her time as a doctoral student at UCSF. She focused on sharing only what she was confident in—mostly dry pharmacy topics.
• An epiphany struck during a trip to the Teotihuacan pyramids in Mexico, where instead of feeling embarrassed by her ignorance, she leaned into it with curiosity. This inspired her to create a video about the pyramids.

“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)

• The realization: her audience was drawn not to her expertise, but to her contagious curiosity.

3. Science Communication and the “Contagion” of Curiosity

• Bhatt remarks on the paradox of our era: infinite information is available, yet misinformation and confident nonsense spread faster than verified science.

“[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)

• Her mission became clear: to translate rigorous, awe-inspiring research into captivating stories that reach the broadest possible audience.

4. Democratizing Scientific Discovery

• Science, Bhatt insists, is for everyone—not just for scientists or those with credentials.
• She describes a breakthrough experiment by geologist Manuel Garcia Ruiz. By tweaking a famous origin-of-life experiment to use Teflon instead of glass, researchers found that silica in glass was crucial to forming DNA building blocks and protocells—suggesting life may have begun on Earth much earlier than thought.

“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)

• Bhatt highlights another recent scientific milestone: for the first time, a human embryo implanting in uterine tissue was observed in real time. Insights gained validated experiences reported by countless women, connecting scientific discovery with lived human reality.

“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)

5. A Call to Glorious, Unapologetic Curiosity

• Drawing together her story, Harini Bhatt reflects: Discoveries aren’t made by those who already know, but by those obsessed with the unknown.
• She invites listeners to seek out their own “Teotihuacan”—the fascination that lights them up precisely because it isn’t already familiar.

“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)
