    Physics Professor: How Much Power Does a UFO Really Need?

    11/11/2026 | 44 mins.
    Most UAP probably aren’t alien spacecraft. A physics professor says so himself, and in these slides one UFO photo turns out to be a seagull while a colleague’s analysis of crash debris found more Earth dirt than he expected. Subscribe if you want science with evidence, not speculation.

    I sit down with Kevin Knuth, a physics professor at the University at Albany, who walks me through his slides on one question, how anomalous is anomalous when it comes to UAP. He answers it with energy and power, because some sightings leave enough data to work out how much power a UAP would need.

    I push back on whether every sensor is giving a true signal, not an artifact or a hallucination, and the debate carries over to my podcast conversation with Kevin.

    What you’ll hear:

    A radar return that is also visible puts a bound on the dielectric constants.

    Systematic error can’t be estimated without knowing the true value, so the acceleration comes out as a probability distribution.

    At 99.9% efficiency, a craft drawing 1,000 gigawatts would still shed about a gigawatt as waste heat.

    The night NASA put an astrophysicist on climate science, the book he bought was a kids’ book on clouds.

    “I’m asking the question, how anomalous is anomalous when it comes to UAP?” Kevin Knuth

    Princeton Mathematician: Wormholes Can’t Survive Einstein’s Math

    03/11/2026 | 56 mins.
    A Princeton mathematician says wormholes cannot survive Einstein's equations, and the AI apocalypse is absurd. A solution that vanishes under a small nudge is a ghost, not physics.

    Sergiu Klainerman is a mathematician at Princeton University. With Demetrios Christodoulou, he proved that empty spacetime is stable.

    We cover: What makes a solution of Einstein's equations physical, why slowly rotating black holes pass the stability test and wormholes fail it, why shocks form no matter how small the perturbation, whether AI can reproduce a landmark proof, and why he calls the AI singularity absurd.

    Mathematics is discovered, not invented.

    00:00 Are wormholes real?

    08:38 What happens at an event horizon

    Are We in a SIMULATION? | Brian Keating on the Arora Podcast

    01/11/2026 | 1h 54 mins.
    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

    27/10/2026 | 44 mins.
    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.

    Max Tegmark: We’re Building A Replacement Species

    23/10/2026 | 57 mins.
    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.

    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?

    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. Superintelligence? Legal.
    31:01 What Bernie Sanders and Steve Bannon agree on
    37:12 Fields medalist: no math jobs after 2027
    42:35 Does the Fermi paradox lower P(doom)?
