String theorys rival: alive & well, YouTubers wrong again. #physics #universe Phil Halper (aka Skydivephil) 2024-09-07 | PBS Space Time, Fermi Lab, and other YouTube physics channels have all said we can test Strng's theory's main rival, Loop Quantum Gravity, by looking for a deviation from something called Lorentz Invaraincne. But what is Lorentz Invariance, and does Loop Quantum Gravity predict this? Do new measurements rule the theory out, as Biran Keating claimed in a new video? Watch here to find out the truth, not the hype. If you want to see what loop theorists say about the theory, watch our documentary starring Carlo Rovelli, Abhay Ashtekar, Lee Smolin, Francesca Vidotto, and Aurelien Barrau.

Creationists debunked by his own source. Subboor Ahmad vs Elliott Sober Phil Halper (aka Skydivephil) 2024-08-23 | Subboor Ahmad is a Muslim evolution critic who likes to quote academics to support his case. One in particular is Elliott Sober, whom Subboor described as "one of the leading philosophers, one of the most recognized philosophers in the world, in particular, in regards to the philosophy of biology and the philosophy of science. " But this is perhaps one of the only things Subboor gets right. In this video, Elliott Sober reviews Suboor's arguments against evolution and human/chimp common ancestry.

Roger Penrose refutes his critics: defending the singularity theorem Phil Halper (aka Skydivephil) 2024-07-25 | Roger Penrose won the Nobel Prize for showing black holes are real and General Relativity predicts the existence of a singularity at their center. But recently, another black hole pioneer, Roy Kerr, claimed there was a mistake in Penrose's proof. This was hyped widely across the media by the likes of Sabine Hoseenfelder, PBS Spacetime, Anton Petrov, and Ethan Siegel. Sabine Hossenfelder especially praises Kerr's work. However, leading relativists say Kerr makes simple errors, and his conclusion is totally unfounded. Here, we talk to these experts and explain how science popularisers got their physics so badly wrong. Nobody claims that singularities are real, but the singularity theories are powerful signposts to new physics, probably requiring a quantum theory of gravity to resolve.

Replying to the New Kalam with Joe Schmid, the Sci Phi Show Phil Halper (aka Skydivephil) 2024-06-07 | We've debunked the old Kalam argument presented by William Lane Craig in other videos, see here:youtube.com/watch?v=pGKe6YzHiMEyoutube.com/watch?v=femxJFszbo8&t=1411sBut there is now a "new" Kalam based on Benardete paradoxes such as the Grim Reaper which are meant to establish something called causal finitism. What are these paradoxes ? and how can a critic of the Kalam respond?Well our very own Alex Malpass has teamed up with Joe Schmid of the Majesty of Reason and published a paper in one of the worlds leading philosophy journals Mind.

Whats inside a black hole? Fuzzballs, Echoes & The Big Bang #black hole #science #space Phil Halper (aka Skydivephil) 2024-05-17 | What's inside a black hole? Physicists have been struggling with this question for decades, but recent work in theoretical physics has revealed an exciting new idea. That a black hole should be replaced with a fuzzball. In this film, we talk to the father of Fuzzballs, Samir Mathur, and his close colleague Nick Warner, a former student of Stephen Hawking, who explain how fuzzballs can solve Hawking's greatest mystery, the information paradox. We also talk to astrophysicist Niayesh Afshordi, the father of black hole echoes, who'll reveal how they might enable us to peer inside a black hole and tell if string theory's fuzzballs are really lurikng inside.And if the black hole singularity is resolved, what about the Big Bang ?

The Sci-Phi Show: Hourglass Universe vs The Kalam Argument Phil Halper (aka Skydivephil) 2024-04-30 | Many contemporary models of the Big Bang from The Hartle Hawking model to Loop Quantum Cosmology to String Gas Comsology, the Janus Universe, Carroll Chen, Aguirre-Gratton, and CPT symmetric universe, can be interpreted as giving the universe an hourglass-like structure. In this episode of the SciPhi Show, leading atheist philosophers Alex Malpass and Dan Linford examine what this might mean for the Kalam Cosmological Argument. In particular, we show that it faces an "interface dilemma" where defenders of the argument, like William Lane Craig, must give up one of the Kalam's fundamental premises. For my videos on the early unvierse, see here:youtube.com/watch?v=Ry_pILPr7B8&list=PLJ4zAUPI-qqqj2D8eSk7yoa4hnojoCR4mFor the Kalam, see here:youtube.com/watch?v=pGKe6YzHiME&t=2798sand here youtube.com/watch?v=femxJFszbo8&t=761sFor Dan's paper, see here:arxiv.org/abs/2006.08890a timecode is below 0:00 Introduction 1:21 What is the Kalam?3:11 Hourglass Universe 6:05 The Interface Dilema 14:55 The Metaculus16:55 Causality 22:30 Simultaneous Causation 25:50 Theories of Time 44:07 Challenging the Causal Principle

DESI: New Dark energy survey results can change physics Phil Halper (aka Skydivephil) 2024-04-09 | DESI, the Dark Energy Spectroscopic Instrument, has just released its first results, and they are not entirely consistent with standard cosmology. In particular, we've been told for decades that the universe's fate is a heat death, with the universe expanding forever into the future. But this assumes that dark energy is constant over time. The new DESI results challenge that. It seems dark energy might weaken over time, maybe even allowing the universe to be cyclic.

Has the Big Bounce been ruled out? Phil Halper (aka Skydivephil) 2023-12-15 | Earlier this year, Scientific American published an article with the headline "The Universe Began with a Bang, Not a Bounce," claiming that a new analysis of the European Space Agency's Planck Satellite speaks powerfully against the Big Bounce model from Loop Quantum Cosmology (LQC). LQC is a cosmological model inspired by the mother theory of Loop Quantum Gravity ( a rival to string theory). However, one of the researchers mentioned in the article, Ivan Agullo, argues the story is totally misconceived, and the evidence is consistent with a Bounce. In this film, he explains why.

Atheisms Best Argument? The Problem of Animal Suffering & The Neuroscience of Pain Phil Halper (aka Skydivephil) 2023-09-29 | The problem of animal suffering (a version of the problem of evil) has recently been described as the biggest problem for Christianity. However, a new paper in the International Journal for Philosophy of Religion suggests that the problem is far worse than imagined. Here, we explain why and counter attempts by theists to reply. The film has 3 sections:Section 1 We meet the authors of this paper and others who explain the EPAS (The Expanded Problem of Animal Suffering). Sections 2 We review various theistic replies to animal suffering and show how atheists, agnostics and other religious skeptics reply.Section 3 We discuss claims made by leading Christian thinkers like CS Lewis, Michael Murray, Richard Swinburne, and William Lane Craig that neuroscience implies we should downplay animal suffering. This is something we tackled many years ago, but since then, a rare patient who had key cortical regions knocked out enables us to do a direct experimental test of the claims of these theologians. Namely testing his pain perception. The results were published in a paper in Philosophical Psychology, and the authors of that paper are in this video explaining why these findings are devastating for the one explanation that might undermine the Expanded Problem of Animal Suffering. This film stars the authors of both of these papers, including lead author Phil Halper (aka skydivephil), philosopher of consciousness Ken Williford, neuroscientist David Rudrauf, pain expert Perry Fuchs, as well ethicists Peter Singer and Mark Bernstein, and philosopher Joe Schmid and Within Reason host Alex O'Connor (the artist formerly known as cosmic skeptic).

The fine tuning argument: a theological critique Phil Halper (aka Skydivephil) 2023-08-18 | Hans Halvorson is a Christian and a Professor of Philosophy of Physics at Princeton University. He is skeptical that the universe is fine tuned for life. However , if it is, he thinks it's evidence against God's existence and thus for atheism. This clip is taken from our longer film on the subject, showing a skeptical take on the fine tuning of the universe for life. Featuring Roger Penrose, Carlo Rovelli, Sean Carroll, Alan Guth and many other leading experts. We cover problems of probability, the multiverse, cosmological natural selection and related issues that potentially debunk the fine tuning argument.You can see that film here: youtube.com/watch?v=jJ-fj3lqJ6M&t=1462sa reply to this argument can be found here:youtube.com/watch?v=QJYWkqOzUQ0&t=4036sand our counter reply here:youtube.com/watch?v=zNH-ZgSpBuQWith thanks to Chris (morn1415) for the fabulous images.
Did the Universe Begin? Rethinking the Penrose Hawking & BGV theorems Phil Halper (aka Skydivephil) 2023-07-28 | The Big Bang happened but was it really the beginning of time? Two theorems are often used to suggest it was: The Penrose Hawking Theorem and the BGV Theorem . But new papers out in 2023 have re examined the issue of the beginning and come to a surprising conclusion. We talk to Roger Penrose, Alan Guth, Alex Vilenkin, Ghazal Geshnizjani, Robert Brandenberger, Damien Easson and Niayesh Afshordi to discuss the ultimate question of whether or not the universe had a beginning.

The Fine Tuning Argument debunked by a Jar of Beans Phil Halper (aka Skydivephil) 2023-06-30 | The fine tuning argument for God claims that a fine tuned universe for life is far more likely given God than without God. It's based on the notion that it is extremely unlikely that we could get life permitting values for the constants of nature without a designer. In this short film, Chris Hitchcock, Professor of Philosophy at Caltech and an expert in probability theory and the philosophy of science offers a critique. This clip was taken form a longer film on the subject, you can see here:youtube.com/watch?v=jJ-fj3lqJ6M&t=1221s for a reply from the proponents of the argument see here:youtube.com/watch?v=QJYWkqOzUQ0&t=4036sand for our counter reply see here:youtube.com/watch?v=zNH-ZgSpBuQ&t=2319s
The S8 Tension & the Euclid Satellite : A New Crisis in Cosmology? Phil Halper (aka Skydivephil) 2023-06-02 | In a previous film we covered the Hubble Tension, the fact that measuring the expansion rate of the universe with supernova data yields a significantly different value than with the cosmic microwave background. In the film we report on a new tension called the S8 tension. This has the potential to be even more significant than the Hubble tension. Solutions to it may even change the origin and fate of the universe, describing a time before the Big Bang and dark energy that is not a cosmological constant which may lead to very different fate to the universe. It may also enable us to find signs of quantum gravity theories like String theory or casual sets in the sky. Finally we'll see how ESAs Euclid mission may confirm if the tension is real or just a measurement error. 0:00 Introduction 0:58 Structures in the universe 5:04 what is S8?6:07 measuring S87:08 It doesnt match 10:11 comparison with the Hubble tension12:12 Cosmological constant 13:30 early dark energy15:04 causal set quantum gravity 17:02 string theory to the rescue?20:16 The Euclid Satellite
Before the Big Bang 11: Did the Universe Create itself ? The PTC model Phil Halper (aka Skydivephil) 2023-04-28 | What happened before the Big Bang? In two of our previous films we examined cyclic cosmologies and time travel universe models. Specially, the Gott and Li Model youtube.com/watch?v=79LciHWV4Qs) and Penrose's Conformal Cyclic Cosmology youtube.com/watch?v=FVDJJVoTx7s) . Recently Beth Gould and Niayesh Afshordi of the Perimeter Institute for Theoretical Physics have fused these two models together to create a startling new vision of the universe.

The reason for this is that, unlike bounce models with a net expansion each cycle, our model has an effective contraction during the conformal phases. Periodic time, therefore, has a unique character in which it reuses the power spectrum from the previous cycles, which is confined to a given form due to the constraints of the system, rather than removing the old power spectrum and needing to produce a new one."
The Fine Tuning Argument: the critics strike back Phil Halper (aka Skydivephil) 2023-03-17 | At the end of of 2022, we released a film offering a reply to the fine tuning argument for God from leading physicists and philosophers of physics. This included both those that doubt there is any fine tuning and those that think there is but it can be solved by naturalistic means. Subsequently astrophysicist Luke Barnes and philosopher Philip Goff offered their criticism of our criticism. Here we have assembled some of our original talking heads to review their criticism and offer a reply, defending the original position that fine tuning argument for God does not work. Our original film can be found here: youtube.com/watch?v=jJ-fj3lqJ6MLuke Barnes and Philip Goff’s reply is here: youtube.com/watch?v=QJYWkqOzUQ0&t=4036sand we also recommend this video on Bayes theorem on the Majesty of Reason Channel: youtube.com/watch?v=o1MdtyLL3Uw&t=4423sOur panel consists of Graham Priest , Distinguished Professor of Philosophy at The Graduate Center, City University of New York, well known for his work in logic especially non classical logic, the philosophy of mathematics and science and Buddhist philosophy. Barry Loewer, who is the distinguished professor of philosophy at Rutgers University and director of the Rutgers Center for Philosophy and the Sciences. Barry specialises in philosophy of science and philosophical logic and the foundations of quantum mechanics, statical mechanics and probability .Dan Linford who is one of the rising stars in the intersection of the philosophy of physics and philosophy of religion. He did his Phd in philosophy, under Paul Draper and had well known atheist cosmologist Sean Carroll and theistic fine tuning advocate Rob Collins on his thesis committee. He’s now doing a postdoc at the University of Nebraska and recently authored the book Existential Inertia and Classical Theistic Proofs with Joe Schmidt. Niayesh Afshordi who is an astrophysicist and cosmologist , he’s Professor at the University fo Waterloo and faculty at the Permitter Institute for Theoretical physics.

Physicists & Philosophers debunk The Fine Tuning Argument Phil Halper (aka Skydivephil) 2022-11-17 | The Fine-Tuning Argument is often seen as the best argument for the existence of God . Here we have assembled some of the world's top physicists and philosophers to offer a reply. Not every critic of the argument comes from the same perspective. Some doubt there is a problem to be solved whilst others agree it is a genuine problem but think there are better solutions than the God hypothesis. Some like the multiverse and anthropics other don’t. We have tried to represent these different approaches and so it should be taken as given, that not all of the talking heads agree with each other. Nevertheless, they all share the view that the fine-tuning argument for God does not work. Nor are all the objectors atheist, Hans Halvorson offers what we think is a strong theological objection to the argument. This film does not try to argue that God doesn’t exist only that the fine-tuning argument is not a good reason to believe in God. Most of the footage was filmed exclusively for this film with some clips being re-used from our Before the Big Bang series, which can be viewed here: youtube.com/watch?v=Ry_pILPr7B8&list=PLJ4zAUPI-qqqj2D8eSk7yoa4hnojoCR4m All of the critics of the fine tuning argument that appear were sent a draft of the film more than a month before release and asked for any objections either to their appearance, the narration or any other aspect of the film. No objections were raised, and many replies were extremely positive and encouraging. A timeline of the subjects covered is below: (We define God as a perfect Omni immaterial mind as for example modern Christians and Muslims advocate, there are other conceptions of God which our video does not address).

Kalam Cosmological Argument 2.Physicists and Philosophers strike back Phil Halper (aka Skydivephil) 2022-07-15 | This is the second film we have made, critiquing the Kalam Cosmological Argument. Our first assembled many leading physicists and philosophers to offer what they think is wrong with the argument. It clearly got the attention of William Lane Craig as he made a four part series responding. In this film we reply to his reply. There are yet agin many leading experts here including Sean Carroll, Carlo Rovelli, Niayesh Afshordi, Adrain Moore, Alex Malpass and others. We also made a 6 hour long response video with Dan Linford ( who also appears in this film ), James Fodor and Digital Gnosis . Find that here: youtube.com/watch?v=txG_iVmtgpo&t=4480sAll opinions expressed are those of the person expressing them and should be taken as a collective opinion.

Physicists & Philosophers debunk the Kalam Cosmological Argument featuring Penrose, Hawking, Guth Phil Halper (aka Skydivephil) 2022-01-14 | We have assembled some of the world’s leading physicists and philosophers to reply to the Kalam Cosmological Argument for God (as presented in popular debates by the Christian Philosopher William Lane Craig). The argument says that everything that begins to exist has a cause, the universe began to exist, therefore the universe has a cause, which must be God. We show the flaws in this argument, featuring interviews we conducted with physicists Roger Penrose, Stephen Hawking, Alan Guth, Carlo Rovelli, Alex Vilenkin, Niayesh Afshordi and many others as well as philosophers such as AW Moore (co-editor of the world's leading philosophy journal Mind), Oxford logician Daniel Isaacson, Cambridge philosopher Arif Ahmed, philosopher of science specialising in foundations of quantum mechanics Alastair Wilson, and Alex Malpass and Daniel Linford who have both published multiple articles on the Kalam in leading journals. Most of the footage was shot especially for this film and all of those participants reviewed it carefully before release. All of the other living participants, where we reused interview footage from previous films, were sent a draft of this one in advance and asked if they objected to appearing or wanted changes. None objected and all changes are in the final film you see. Most participants gave extremely positive feedback and we hope you will too.Timecodes0:00 Introduction 1:38 Actual versus Potential Infinity 2:40 Cantor's Infinity 3:06 The Infinite Property 5:42 Hilbert’s Hotel 11:16 Contradiction & not a Contradiction 13:38 Jupiter and Saturn 14:52 Physicists on Infinity 16:38 Counting to Infinity 18:36 The Infinite Future 22:35 Spacetime Singularity 24:50 Carlo Rovelli on Neo Lorentzian Relativity and Cosmic Time 28:29 Hawking, Penrose, Vilenkin, Efstathiou on The Big Bang & Quantum Gravity 29:37 Strings, Loops and the Big Bounce 31:16 Guth and Vilenkin on the BGV 34:00 Is a Collapsing Universe Unstable? 35:31 Wall Theorem, Ashtekar and Afshordi 36:36 Anthony Aguirre on Past Eternal Universe 37:47 Singularities, Magueijo and Vidotto 38:24 Second Law, Guth and Ashtekar40:43 A Universe From Nothing?
