Channel Title: Phil Halper (aka Skydivephil) Channel Description: Leading experts discuss science and philosophy with a focus on cosmology, the big bang , black holes, evolution, and atheism /agnosticism <video> Big Bang to evolution drone show Description: This amazing drone show tells the story of cosmic history, from the Big Bang to the first galaxies to planets, life, and technology. Celestial presented it at Edgbaston Stadium on October 26th, 2024. </video> <video> Cosmologists debate: Was the Big Bang the beginning? Description: Was the big bang the beginning of time or was there a before the big bang? Here two of the world's leading cosmologists debate whether the universe had a beginning or not. Featuring Thomas Herzog who was one of Stephen Hawking's main collaborators on his No Boundary or Hartle/Hawking model and Robert Brandenberger one of the authors (along with leading string theorist Cumrun Vafa) of Sting Gas Cosmology. Thomas's book One the Origins of Time, can be found here: https://www.amazon.co.uk/Origin-Time-Stephen-Hawkings-theory/dp/1911709089 and my upcoming book, The Battle of the Big Bang can be pre ordered here: https://press.uchicago.edu/ucp/books/book/chicago/B/bo244963115.html Our film on the No Boundary Proposal which starred Stephen Hawking, Jim Hartle and Thomas Herzog can be found here: https://www.youtube.com/watch?v=Ry_pILPr7B8&t=1569s A timeline is below 00:00 Introduction 1:10 on being Stephen Hawking's PHD student 2:17 Robert's story 4:02 Does the CMB prove a beginning? 7:52 Penrose Hawking Singularity 17:15 Inflation and the BGV theory 24:38 The Hartle Hakwing No Boundary Proposal 36:14 Emergent universe 46:14 Holography 58:00 Entropy 65:00 Can we even know if the universe begun? </video> <video> Did string theory lie? fact checking a critic Description: Here, Professor Nicholas Warner and I debunk the claims that string theory lied to the public and that this caused public mistrust of physics, a claim made by scientists and YouTube Angela Collier. In particular, we show evidence that Brian Greene gave the relevant caveats she rightly demanded. Obviously, there's much more to say about the subject, and we have plenty of information. A timeline is below: 00:00 Introduction 2:24 Did Brian Greene lie? 11:44 What was claimed? 18:36 Angela vs data 24:39 String theory history 30:48 What is a theory anyway? 36:52 supersymmetry 43:08 multiverse 50:05 What did Susskind really say? 1:00:00 Wikipedia and string theory 1:02 :00 What did Nova actually say? 1:07:21 other physicists 1:14:10 The irony of Pauli 1:15:48 the 2010's 1:18:00 Angela timewarp problem 1:28:45 Sheldon Cooper and the Big Bang Theory 1:34:00 what is coming next 1:37:53 summing up A link to the debate I hosted between Carlo Rovelli and David Gross on string theory vs loop quantum gravity is here: https://www.youtube.com/watch?v=AUyylR5RPZw&t=1615s </video> <video> Physicists search for Black Hole Bombs Description: What is a black hole bomb? Have alien civilizations already made them? Could they form naturally? Can we use them as particle detectors? And how could astronomers find them out there in the cosmos? Two of the world's leading experts, Vitor Cardoso and Niayesh Afshordi discuss these fascinating topics.

Exclusive: new DESI results revealed Description: DESI is the Dark Energy Spectroscopic Instrument, and in this exclusive video, we talk to one of its chief scientists about new results that may revolutionize cosmology. The video is set to release at the very moment the embargo on the new data will be lifted and revealed to the public and we will learn if our understanding of the universe needs radical revision or not. </video> <video> Atheists Debunk Phillip Goff's Limited God. The Sci Phi Show 9 Description: In this episode of the SciPhi Show, philosophers Alex Malpass and Dan Linford join me to discuss Philip Gofs's conversion to Christianity. We give an atheist perspective on the relevant arguments,s including fine-tuning, the problem of evil, atonement, resurrection, and morality. A timeline of the show is here: 00:00 introduction 3:00 fine-tuning and problem of evil 29:07 crazy coincidence 33:32 Goff's theory of the atonement 50:39 the resurrection 59:59 Origins of Christianity 1:01:00 Morality You can read Goff's article here: https://aeon.co/essays/i-now-think-a-heretical-form-of-christianity-might-be-true and Alexs blog post is here: https://useofreason.wordpress.com </video> <video> Alex O'Connor defended. Christian critique backfires.The Sci Phi Show 11 Description: Alex O'Connor and I recently debated well-known internet preaching stars Stuart and Cliffe Knechtle on the topic: Does the Biblical God Exist?. But Cameron Bertuzzi from Capturing Christianity claims Alex embarrassed himself. In this video, philosophers Alex Malpass and Dan Linford join me in picking up apart not just the bogus claims of the Kenchtle's, but also debunk Cameron's ironic errors. Timeline: 00:00 Introduction 4:27 Cameron's first error 11:32 Cameron's second error 18:49 History 31:42 Expectations 44:12 Ad hominem 52:55 Stuart and Cliffe review For more episodes in this series, see https://www.youtube.com/watch?v=e8vB3ZyS3dY&list=PLJ4zAUPI-qqprexGfnGwCpugHnUuSjPmG </video> <video> Alex O'Connor's Christian Conundrum: Still Unsolved .

Unsruprisingly, the 3 questions provide no real challenge at all. </video> <video> How to make a Black Hole Bomb #physics Description: Physicist Vitor Cardoso explain how an alien civilisation could build a black hole bomb </video> <video> A fractal universe? Asymptotically safe quantum gravity Description: What happened before the big bang? Most cosmologists agree we need a quantum theory of gravity to answer this question. You may have heard of string theory or loop quantum gravity, but in the 1970s, Nobel Prize Winner Steven Weinberg created another theory of quantum gravity: Asymptotic Safety. Recently, it has been revived, especially as it seemed to precisely predict the mass of the Higgs Boson. In this film, we talk to some of the leading researchers in the field to understand this theory and what it might say about the universe's origins. 00:00 Introduction 01:00 Fractal Universe 2:12 Asymptotic safety 5:03 Predicting the value of the constants 9:07 Supersymmetry 10:37 History of ASG 13:10 Answering the critics 14:51 Black holes 16:10 Big Bang 19:46 What happened before the Big Bang? 21:14 Did the universe have a beginning? 24:44 Scale invariance </video> <video> 5 Black Hole Alternatives & how to find them Description: Leading physicists examine 5 possible alternatives and how we might empirically find them inlcuindg boson stars, gravastars, fuzzball, black shells and Planck stars. 00:00 Introduction 2:48 Boson stars 5:37 Gravastars 9:14 fuzzball 11:27 Blake Shell and Higher dimensions 13:27 Planck Stars 16:22 empirical tests 18:21 Black Hole Echoes 22:54 Radio telescope Images For more black hole videos see our black hole playlist here: https://www.youtube.com/watch?v=X7mpbxJHWyM&list=PLJ4zAUPI-qqoP-kAJmaXJwllMtrPpy1cV </video> <video> Hawking vs Penrose: Black Hole information loss defended Description: In 2004, Stephen Hawking conceded that blakc holes do preserve information in a famous bet with physicist John Preskill. But was he right to do so? In this film, some of the biggest names in relativity, like Roger Penrose, Bill Unruh, and Bob Wald, argue he was not. Moreover, they say the modern consensus that black hole information loss is a great threat to physics is wrong. Black holes do lose information.

The Sciphi Show 10 Description: In the latest episode of the SciPhi show, Alex Malpass, Dan Linford, and I expose the nonsense argument and scientific ignorance of crackpot astrophysicist Hugh Ross, who claims that demons exist, UFOs are demons, the Bible teaches the Big Bang theory, and God exists in extra dimensions of time. #science #athiest #athiesm #skeptic #sceptic A link to Mctaggerts paradox is here: https://www.youtube.com/watch?v=iB7xZR-1L5M A timeline is here: 00:00 introduction 1:41 Demons 13:11 UFO's 25:35 extra time dimension 36:43 problem of animal suffering 53:04 Spacetime and The Bible 55:24 Why an old universe? </video>
