    Astrophysicist DEBUNKS Bart Sibrel’s Moon Landing Conspiracy Theory

    Astrophysicist DEBUNKS Bart Sibrel’s Moon Landing Conspiracy Theory

    In 1969, Apollo 11 was the first crewed mission to land on the Moon.

    Or was it?

    According to conspiracy theorists, it's obvious that the moon landing was faked. Now, I don't usually pay much attention to such claims, but a few days ago Joe Rogan published a new episode of his podcast, in which he hosted none other than Bart Sibrel himself, giving him a platform to spread his anti-science nonsense to millions of people around the world.

    So, as a scientist, more specifically an astrophysicist, I feel that it is my duty to debunk his claims one by one and to explain the science behind the Apollo 11 mission.

    Tune in!

    There are many stories, notions, and theories about what might happen if the development of artificial intelligence goes wrong. But what if it goes right? What if we develop superintelligence safely, govern it well, and make good use of it?

    These are the profound questions that today’s esteemed guest, Nick Bostrom, has explored in his highly anticipated new book, Deep Utopia.

    Nick is a Professor at Oxford University, where he heads the Future of Humanity Institute as its founding director. He is the most-cited professional philosopher in the world aged 50 or under and is the author of some 200 publications, including Anthropic Bias (2002), Global Catastrophic Risks (2008), Human Enhancement (2009), and Superintelligence: Paths, Dangers, Strategies (2014), a New York Times bestseller.

    With a background in theoretical physics, computational neuroscience, logic, and artificial intelligence, he is a leading expert in this field so without further ado, let’s dive right into his beautiful utopia!

    How are cosmology and cosmetology linked? Has the Big Bang happened an infinite number of times? And why has no one ever seen a perfect triangle? 

    I recently had the opportunity to discuss these and other exciting topics with Dennis Prager! Dennis is the host of the nationally syndicated radio talk show The Dennis Prager Show, which can be heard nationwide on nearly 400 stations! He is also the founder of Prager University (PragerU), the world's most-watched conservative video website with a billion views a year, more than half of them by people under 35. 

    Enjoy our insightful conversation! 

    Key Takeaways:


    00:00:00 Intro

    00:00:55 Cosmology and cosmetology 

    00:04:58 The origin of the universe 

    00:09:01 The perfect triangle 

    00:13:01 The first scientific crack in cosmology and Olber’s paradox

    00:18:26 Do most physicists believe in the Big Bang? 

    00:22:59 My predictions about the past

    00:27:50 Outro

    Exploring the Scientific Validity of the Multiverse Theory w/ Paul Halpern

    Exploring the Scientific Validity of the Multiverse Theory w/ Paul Halpern

    Join my mailing list https://briankeating.com/list to win a real 4 billion year old meteorite! All .edu emails in the USA 🇺🇸 will WIN!

    The multiverse has captured the imagination of scientists and thinkers for centuries, sparking debates in physics, philosophy, and beyond.

    But is it a valid scientific theory or just science fiction? 

    I’ve had the pleasure of exploring this issue with the leading expert in this field, physicist and author Paul Halpern. Halpern is a professor of physics at Saint Joseph’s University and the author of eighteen popular science books, including Flashes of Creation, The Quantum Labyrinth, Einstein's Dice, Schrodinger's Cat, and Synchronicity. He is the recipient of a Guggenheim Fellowship and is a Fellow of the American Physical Society. 

    Halpern recently published The Allure of the Multiverse: Extra Dimensions, Other Worlds, and Parallel Universes, which tells the epic story of how science became besotted with the multiverse and the controversies that ensued. Today, we’re going to dive headfirst into this fascinating investigation!

    Tune in.

    Key Takeaways:


    00:00:00 Intro

    00:01:17 Judging a book by its cover

    00:06:39 Bruno’s speculations about exoplanets

    00:11:20 Why is the multiverse such a controversial theory? 

    00:16:54 Richard Feynman And John Wheeler

    00:23:31 Can we falsify the multiverse?

    00:30:30 Has anyone ever written a biography of Bob Dickey? 

    00:39:11 Inflationary models, multiverse and cyclic cosmology

    00:45:36 Evidence of bubble collisions in the CMB? 

    00:57:45 String theory and the multiverse

    Daniel Dennett: Do We Have Free Will?

    Daniel Dennett: Do We Have Free Will?

    Join my mailing list https://briankeating.com/list to win a real 4 billion year old meteorite! All .edu emails in the USA 🇺🇸 will WIN!

    Welcome everyone to a fascinating deep dive with the late Daniel Dennett!

    In our interview, we tackled fascinating problems like free will, human consciousness, ethics, and the philosophy of science. He also explained why he’s sounding the alarm on AI!

    Shortly after our interview, Daniel sadly passed away at the age of 82. He was a renowned philosopher, thought-provoking writer, brilliant cognitive scientist, and vocal atheist. He was the co-director of the Center for Cognitive Studies, the Austin B. Fletcher Professor of Philosophy at Tufts University in Massachusetts, a member of the editorial board for The Rutherford Journal, and a co-founder of The Clergy Project.

    Known as one of the "Four Horsemen" of New Atheism, he was at the forefront of discussions on consciousness, free will, and the impact of Darwinian evolution on religious belief. Dennett's works, including "Breaking the Spell" and "Consciousness Explained," have provoked both admiration and controversy, challenging readers to reconsider deeply held beliefs about the mind and its relationship to the physical world. Needless to say, I was thrilled to have Dan on the show!

    The world has truly lost an extraordinary soul and a groundbreaking thinker.

    RIP
