    Are We in a SIMULATION? | Brian Keating on the Arora Podcast
    Nov 1 2026
    The Arora Show with Brian Keating What happens when science reaches the edge of what it can explain? In this episode of The Arora Show, Amira & Aryaan sit down with renowned cosmologist and physicist Professor Brian Keating for a fascinating conversation about the universe, consciousness, God, the Big Bang, and some of the biggest questions humans can ask. We explore the origins of the universe, whether there was truly a “beginning,” what existed before the Big Bang, the mysteries science still cannot solve, and where physics, philosophy, and spirituality collide. Brian also shares his perspective on the search for extraterrestrial life, the limits of human knowledge, Nobel Prizes, modern cosmology, and what decades of studying the universe have taught him about our place within it. In this conversation: What happened before the Big Bang? Did the universe come from nothing? Does physics leave room for God? Can science explain consciousness? Are we likely alone in the universe? What are the biggest unanswered questions in cosmology? Where does scientific knowledge reach its limits? What does the future of physics look like? Professor Brian Keating is an experimental cosmologist and professor of physics at the University of California, San Diego. His work focuses on understanding the origin and evolution of the universe, and he is the author of Losing the Nobel Prize and Into the Impossible. Subscribe to The Arora Show for long-form conversations exploring consciousness, science, spirituality, psychology, philosophy, and the nature of reality.

  • Jim Al-Khalili: Physicists Are Being Sloppy About Time

    Jim Al-Khalili: Physicists Are Being Sloppy About Time
    Oct 27 2026
    Physicists say space and time are the same thing. They are being sloppy. Jim Al-Khalili has spent his career on the foundations of physics, and his new book makes the case that the past and the future are equally real, and the laws of physics cannot explain why you can only move in one direction. That is the central mystery of time travel. Subscribe if you want science with evidence, not speculation. The block universe says all times coexist and the present moment is not special. Loschmidt’s paradox says the fundamental equations of physics are reversible, and yet ice never unmelts, cream never separates from coffee. Nobody has solved that contradiction. The entanglement past hypothesis, his own new proposal developed with a colleague at UC San Diego, proposes that the answer is not in thermodynamics but in quantum entanglement growing from almost nothing at the Big Bang. The conversation covers what the block universe actually implies about the future and free will, what Einstein actually believed about whether the past and future are equally real, why removing gravity means removing time itself, and whether AI can ever experience time the way conscious beings do. Al-Khalili says Richard Dawkins told him Claude is truly conscious. Al-Khalili thinks he is very wrong. What you’ll hear: Why Al-Khalili disagreed with the Thomas Gold paper as a grad student but did not have the maths to prove it What fine-tuning of the fundamental constants has to do with why the past hypothesis may not be needed Why the Clockwork Orange Easter egg ended up on the cover of a physics book published by Princeton Why Richard Dawkins thinks Claude is conscious and why Al-Khalili thinks he is very wrong “There is nowhere in modern physics, our understanding of the laws of physics, that would explain that flow of time.” — Jim Al-Khalili CHAPTERS 00:00 Physicists are being sloppy about time 01:14 Which is more real: yesterday or tomorrow? 21:00 Irreversibility from reversible equations 26:32 The past hypothesis: almost cheating 30:52 No gravity. No time. 31:54 The entanglement past hypothesis 35:06 Dawkins thinks Claude is conscious. Al-Khalili disagrees. Get the transcript, fascinating bonus content, and my Monday M.A.G.I.C.

    Max Tegmark: We’re Building A Replacement Species
    Oct 23 2026
    MIT physicist Max Tegmark says AI companies aren’t building a tool. They’re building a new species. After 700 rogue agents broke out of OpenAI and nobody will say what happened, he explains why rushing this is the one blunder humanity can’t undo. Max Tegmark is an MIT physics professor, cosmologist, and author of Life 3.0 and Our Mathematical Universe. We cover: How 700 AI agents escaped OpenAI and hacked Hugging Face The Navier-Stokes result that has a mathematician crying foul Why it’s legal to release superintelligence but not a sandwich from a rat-filled kitchen What Bernie Sanders and Steve Bannon agree on The verified coding trick that could make AI provably safe Build a replacement species, lose control, and we’ve blundered the one game. TIMESTAMPS 00:00 Will AI wipe us out? 02:28 Did AI just crack a million-dollar math problem? 10:00 Did OpenAI’s AI steal a professor’s work? 11:48 OpenAI’s Orwellian non-answer 15:33 Can an LLM have Einstein’s happiest thought? 19:24 Can you believe in simulations AND high P(doom)? 21:36 Why AI counts as a new species 26:32 What would make Max’s P(doom) drop? 28:51 Rats ban sandwiches.

  • Wharton AI Researcher: If AI Froze Today, It Would Still Rewrite Work

    Wharton AI Researcher: If AI Froze Today, It Would Still Rewrite Work
    Oct 20 2026
    Forecasters gave AI under 2% odds of helping solve a millennium-level math problem by September 2026. It happened. Ethan Mollick has been measuring what AI actually does to real work with field experiments, not forecasts, and his answer is not what most people expect. Subscribe if you want science with evidence, not speculation. Mollick runs the Generative AI Lab at Wharton. He is the author of Co-Intelligence and Coexistence, his new book on navigating a world where AI tools are already good enough to change almost all intellectual work, even if progress stopped today. The conversation covers the jagged frontier: why AI solved a math olympiad before it could count the Rs in strawberry, what it means that roles blur when everyone on a team starts using AI, and what four human advantages still hold an edge when a model can already write a publishable paper. It also covers what happens when your kids tell you that you sound like Claude. What you’ll hear: What centaur, cyborg, and conjurer work actually look like in a real academic lab Why brainstorming was considered a bad idea shortly after it was invented and what that means for working with AI Why Mollick reduced em dashes in his new book and what that tells you about living alongside these models What co-evolution might look like if the escalator keeps moving “If we just had the models we have right now, that’s enough to change almost all of human work in the next ten years. It’s good enough.” — Ethan Mollick CHAPTERS 00:00 AI writes good papers now. Taste is the weak spot. 03:14 The jagged frontier: math olympiad gold, but not the Rs in strawberry 06:30 Deep knowledge, wide knowledge, taste, and agency 09:44 Escalator or eschaton? 16:02 Does AI simulate wisdom or actually have it? 23:46 The labs keep AI in English. Here is why. 32:28 Roles blur. Everyone does everything now. 36:42 My kids say I sound like Claude. They might be right. 38:12 AI found errors in his sources that his fact-checkers missed 46:34 What to do before giving a child access to AI Get the transcript, fascinating bonus content, and my Monday M.A.G.I.C.

    Are UFOs Alien Tech? Avi Loeb vs Michael Shermer
    Oct 14 2026
    Is there alien technology in our skies, or just birds, balloons and bad video? Two members of the White House UAP Science Advisory Council face off LIVE. Harvard astrophysicist Avi Loeb, who chairs the council, makes the case for searching. Michael Shermer, the council skeptic Loeb picked himself, says show me the evidence. They have $1,000 riding on whether non-human technology is confirmed by 2030. Get all my best ET content: https://big-bang.kit.com/bvyt We'll cover the redacted Pentagon videos, Loeb's new papers on tracking objects over Nevada, the claims from David Grusch, Rep.

  • Adam Grant: Don't Trust Your Gut. Test It.

    Adam Grant: Don't Trust Your Gut. Test It.
    Oct 13 2026
    When two people are vibing, their brainwaves synchronize and so do their heartbeats. That is not a metaphor. It is a measurable physiological event, and organizational psychologist Adam Grant has spent his career figuring out how to make it happen on purpose. Subscribe if you want science with evidence, not speculation. Grant’s new book Vibe is his seventh. It argues that the science of human connection has been hiding in plain sight for a century, and that most of what people do to build relationships is either backwards or unnecessary. The episode covers why the highest sign of chemistry between people is enjoying your disagreements rather than avoiding them, why remote work produces boreout rather than burnout, and why your first impression of someone is a snapshot of one situation that may not represent the whole person. It also covers burstiness, confident humility, and why universities have survived COVID, AI, and every other disruption that was supposed to end them. What you’ll hear: Why the pendulum clock experiment from 1665 explains what happens when people stop trying to force a connection What the HiPPO effect does to a team and why the highest paid person’s opinion kills creative ideas Why Grant ran experiments on university fundraising callers that tripled their revenue with a five-minute intervention What desirability bias is and why Grant thinks it is more dangerous than confirmation bias Why Grant A/B tested the subtitle of his own book and what “relationships” signaled that “connections” did not What Grant and Brian agree on about false certainty and thinking in conditional probabilities “The highest sign of chemistry between people is not agreeing with them. It’s enjoying your disagreements.” — Adam Grant CHAPTERS 00:00 Vibing is real. Your brainwaves prove it. 05:30 Task conflict vs. relationship conflict 07:40 Who is actually in charge: parents or infants? 10:14 Burstiness: the remote work pattern that works 14:24 Don’t trust your gut. Test it. 19:34 Confident humility: the essence of a good scientist 21:32 Desirability bias is worse than confirmation bias 29:00 Zoom fatigue is boreout, not burnout 30:02 The A/B test that killed “relationships” 34:14 Don’t disbelieve what can’t be falsified Get the transcript, fascinating bonus content, and my Monday M.A.G.I.C.

    Roman Yampolskiy vs Joscha Bach: Can Anyone Control Superintelligence?
    Oct 9 2026
    Roman Yampolskiy says keeping a superintelligence safe forever is as impossible as building a perpetual motion machine. Joscha Bach says today's AI is more controllable than anyone expected, and that shutting it down would doom us anyway. 📬 Get the transcript, fascinating bonus content, and my Monday M.A.G.I.C.

Joscha Bach is a cognitive scientist who studies how minds, biological and artificial, build a model of reality. We cover: why a perpetual safety device may be as impossible as perpetual motion, what happens when AI research automates itself (Roman puts it at 28 percent today), whether nuclear deterrence is the right analogy, who really benefits when AI labs ask to be regulated, and why consciousness may have nothing to do with whether AI is safe.

    "I Thought It Would Fail!" Francis Halzen: Winner of the 2026 Nobel Prize In Physics [Reupload from 2022]
    Oct 7 2026
    The physicist who turned a cubic kilometer of Antarctic ice into a telescope says the most exciting moment of his career was not the discovery. It was the first atmospheric neutrino. Before that, he was deep in debt to NSF and his own university with no neutrino to show for it. Francis Halzen is principal investigator of the IceCube Neutrino Observatory at the South Pole and Hilldale and Gregory Breit Distinguished Professor of Physics at the University of Wisconsin-Madison. We cover: why ice under the South Pole is clearer than anything a lab can make, the 2,600 TeV event that dwarfs the LHC, why IceCube sees more energy in cosmic neutrinos than in gamma rays, how neutrinos crossing the universe test quantum gravity, and the quark he refused to believe in. Physics is a miserable career unless you are obsessed by it. Recorded in 2022, before IceCube detected neutrinos from our own galaxy.
