Curiosity Theory

This episode is brought to you by The End of Oak Street, in theaters August 14th.In this special sponsored episode of Curiosity Theory, hosts Justin Shaifer and Dr. Dakotah Tyler break down the real science behind The End of Oak Street, in theaters August 14th.The discussion moves from favorite dinosaurs and the basic premise of the film to the actual physics of what it would take to travel back in time, including the Kardashev scale, E=mc², and why you would need to convert roughly 50 Jupiters worth of mass into pure energy just to get started. From there they get into what prehistoric Earth actually looked like: a planet running hotter than today, with higher oxygen levels, no grass, and a North American interior that was completely underwater.The conversation also covers what you would eat if modern food didn't exist, why the cycad plants that dominated the era would not exactly be a meal, why prehistoric insects could grow to the size of your arm, why a giant frog the size of a beach ball was a real animal, and why none of that is actually what would kill you. The biggest threat to any time traveler isn't the T-Rex — it's the bacteria your immune system has never encountered. They close on the asteroid that wiped out the dinosaurs 66 million years ago and what the world might have looked like if it had missed entirely.Chapters00:00:00 Intro and the premise of The End Of Oak Street 00:01:00 Favorite dinosaurs and what we actually know about them 00:03:02 North America used to be an ocean 00:04:37 The energy physics of time travel and the Kardashev scale 00:08:19 How long could you actually survive without modern technology 00:09:41 Prehistoric climate: how much hotter was it really 00:12:00 What water sources would even be safe to drink 00:15:22 What food was available and why most of it would starve you 00:21:23 Time travel mechanics in the film: wormholes and causality 00:28:31 Why prehistoric insects were gigantic and how oxygen made it possible 00:32:25 Beelzebufo: the giant frog that was very real 00:33:42 Humans vs. prehistoric predators — we were at the bottom 00:42:49 The bacteria and disease that would actually kill you first 00:46:26 Would prehistoric plants make good bio weapons? 00:49:00 Fire, survival skills, and your best chance of making it 00:55:17 What if the asteroid never hit 66 million years ago? 00:55:28 Birds are dinosaurs and why that matters 00:57:50 Final thoughts and why you should go see The End Of Oak StreetFollow us @curiositytheorypod @dr.starkid @mr.fascinateSponsored by The End of Oak Street — in theaters August 14th.Visit our Merch Store https://www.curiositytheorypod.com/merchJoin our Patreon https://www.patreon.com/c/CuriosityTheoryIf you enjoy the conversation, subscribe and share Curiosity Theory with someone who's curious about the universe.

Dr. Taylor Cummings, an educational psychologist and founder of The Self-Love Doc, blends African-centered healing with research on belonging. She probes how Western science sidelines emotion and nonverbal knowledge. Conversations touch on embodiment and why schools stifle curiosity. Personal stories include misdiagnosis, navigating medications, and reclaiming identity through culturally rooted frameworks.

In this episode of Curiosity Theory, hosts Dr. Dakotah Tyler and Justin Shaifer sit down with Joshua Regis, co-founder and CEO of KritKarr, an AI-powered platform for auto repair, for a conversation about fixing one of the most broken industries in America, what the trades are actually worth, and who gets to write the future.The discussion moves from Josh's path out of traditional school and into automotive work, how he discovered that a car contains every trade skill in existence, and how the flat rate pay system exploits the mechanics who keep the industry running. From there they get into what KritKarr is building, how AI diagnostics and mobile mechanics can bring trust and transparency back to auto repair, and why skilled trades are a six-figure opportunity that almost nobody is talking about.The conversation also dives into whether robots will replace mechanics and why the human touch still matters, how automation is set to widen the wealth gap, the SpaceX IPO and what commercializing space actually means for regular people, whether we should be trying to colonize Mars before fixing things on Earth, and what Afrofuturism has to say about who controls the narrative of the future. It opens on the Tulsa Race Massacre and the question of what Black Wall Street could have become, and that thread runs underneath everything.Chapters00:00:00 Intro and meeting Joshua Regis 00:03:00 Black Wall Street, the Tulsa Race Massacre, and what could have been 00:07:28 Sci-fi, anime, and the Tony Stark effect 00:14:50 How Josh went from struggling in school to becoming a mechanic 00:15:44 Why a car contains every trade skill in existence 00:20:35 Flat rate vs hourly: how the auto industry underpays mechanics 00:27:42 What KritKarr is and how it works 00:29:55 Skilled trades as a six-figure career opportunity 00:35:00 Will robots replace mechanics?

Dr. Chanda Prescod-Weinstein, astrophysicist and author exploring particle physics and cosmology. She talks about neutrinos and their strange flavors. She tells the story of turning a blog into a science book. She examines whiteness in scientific norms, why the cosmos can be a Black aesthetic, and how dark skies and culture shape access to astronomy.

In this episode of Curiosity Theory, hosts Dr. Dakotah Tyler and Justin Shaifer sit down with Dr. Naia Butler-Craig, a newly minted aerospace engineer and NASA electric propulsion researcher, for a conversation about rocket science, how we actually move through space, and where humans are headed next.The discussion moves from her path through grad school and into NASA to how electric propulsion works and why it beats chemical rockets on efficiency, what it would really take to get people to the Moon and Mars, and what living and working at the agency is like from the inside. Along the way, she breaks down what is happening inside a Krypton Hall effect thruster and why plasma, not combustion, is the future of deep space travel.The conversation also dives into why astrology is not astronomy, how to think about trust and misinformation in science, the engineering and people behind the missions we take for granted, and the surprising ways space tech is advancing medicine on Earth through Avatar tissue chips. It closes on the sci-fi and the curious childhood that set her on this path in the first place.Chapters00:00:00 Intro and meeting Dr. Naia Butler-Craig 00:01:15 Her path into NASA and life inside the agency 00:11:43 Electric propulsion vs chemical rockets explained 00:17:23 Getting humans to the Moon and Mars 00:24:04 Why astrology is not astronomy 00:31:50 Trust, misinformation, and relying on science 00:37:00 Is NASA still competent?

In this episode of Curiosity Theory, hosts Dr. Dakotah Tyler and Justin Shaifer sit down with KeShawn Ivory, a soon-to-be PhD astrophysicist who studies the large-scale structure of the universe, for a deep conversation about dark matter, cosmology, and the invisible stuff that holds the universe together.The discussion moves from what dark matter actually is to how the universe became clumpy and lumpy instead of smooth, why the first atoms appeared minutes after the Big Bang, and how primordial black holes (a mountain's worth of mass packed into the size of a proton) became one of the more compelling candidates for what dark matter might be. Along the way, they get into how scientists detect something they can't see, what counts as evidence, and how scientific consensus actually moves.The conversation also dives into the hunt for dark matter through detection experiments, the role of skepticism in good science, what it means to know something, and KeShawn's favorite idea of all: that dark matter works as a framework for any force that is deeply impactful but hard to see, from race and systemic disparities in sociology to genomic dark matter in biology and trauma in art.Chapters00:00:00 Intro and meeting KeShawn Ivory00:02:30 The PhD as a credential and the path to science communication00:08:55 What dark matter actually is00:10:00 Why the universe is clumpy: large-scale structure00:11:30 The early universe and the first atoms00:20:30 The cosmic microwave background and the universe's baby picture00:30:00 How we know dark matter is really there00:33:30 Primordial black holes as a dark matter candidate00:40:00 Dark stars and other exotic candidates00:47:40 Healthy skepticism and how scientific consensus moves00:53:00 Science, truth, and what it means to know something00:59:00 The hunt for dark matter: WIMPs, axions, and detectors01:08:00 How theory predicts the particles we look for01:17:50 Astrosociology: dark matter as a lens on race and systemic forces01:24:10 Dark matter as a storytelling tool in biology and art01:26:18 Where to find Kishan and Black Space WeekFollow us@[email protected]@mr.fascinateGuestsKishan Ivory (Dark Mattering)Visit our Merch Storehttps://www.curiositytheorypod.com/merchJoin our Patreon/ curiositytheoryIf you enjoy the conversation, subscribe and share Curiosity Theory with someone who's curious about the universe.

Dakotah and Justin revisit the original idea behind Curiosity Theory: curiosity as a North Star. That quickly turns into an argument over whether wanting to know what is in someone’s fridge counts as curiosity or just being nosy.The conversation eventually gets more serious. They talk about the courage required to question beliefs, why scientific progress often threatens ideas people consider sacred, and the difference between an old belief being useful and actually understanding why it works.Then they get into aging, genetic engineering, designer babies, and immortality. If we eventually learn how to extend human life dramatically, who gets access first? And would society become better, or would the most powerful people simply hold power for even longer?Visit our Merch Storehttps://www.curiositytheorypod.com/merchJoin our Patreonhttps://www.patreon.com/c/CuriosityTheoryFollow the show @curiositytheorypodHosted by Dr. Dakotah Tyler and Justin ShaiferStay curious.
