The Physicist Who Says Time Doesn’t Exist

In today’s episode of Theories of Everything, Curt Jaimungal and Julian Barbour challenge conventional physics by exploring Barbour’s revolutionary ideas on time as an emergent property of change, the universe’s increasing order contrary to entropy, and the foundational nature of shape dynamics.

Scientific literature is growing rapidly, meaning scientists are increasingly unable to keep up with all of the latest developments in research. AI large language models, though, can read and “digest” information much more quickly than their human counterparts, making them the perfect tools to conduct massive literature reviews. Recent research shows they’re also very accurate at predicting the results of studies that they’ve never read before. Let’s take a look.

This Theory of Everything Actually Makes a Prediction: New Physics in Black Holes

Learn science, computer science, and mathematics in the easiest and most engaging way possible with Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.

Mathematician Stephen Wolfram has attempted to develop a theory of everything using hypergraphs, which are essentially sets of graphs that can describe space-time. Recently, another mathematician named Jonathan Gorard has used hypergraphs to describe what happens if a black hole accretes matter. He claims that evidence for hypergraphs should be observable in the energy that is emitted during the accretion. Big if true, as they say. Let’s take a look.

Huge Physics Anomaly Finally Put to Test, But That Just Makes it More Confusing

Check out courses in science, computer science, or mathematics on Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.

Ten years ago, physicists discovered an anomaly that was dubbed the “ATOMKI anomaly”. The decays of certain atomic nuclei disagreed with our current understanding of physics. Particle physicists assigned the anomaly to a new particle, X17, often described as a fifth force. The anomaly was now tested by a follow-up experiment, but this is only the latest twist in a rather confusing story.

New Theory of Consciousness Explains Why Zombies Don’t Exist

🌏 Get NordVPN 2Y plan + 4 months extra here ➼ https://NordVPN.com/sabine It’s risk-free with Nord’s 30-day money-back guarantee! ✌

A collaboration of a neurologist, a computer scientist, and a philosopher has just put forward a new theory of consciousness. It is based on the idea of causal models. The authors claim boldly that their idea solves the hard problem of consciousness and explains why zombies don’t exist in nature. Really? I’ve had a look.

These physicists say they know what’s inside a black hole

I have my own introduction quantum mechanics course that you can check out on Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.

Physicists are obsessed with black holes, but we still don’t know what’s going on inside of them. One idea is that black holes do not truly exist, but instead they are big quantum objects that have been called fuzzballs or frozen stars. This idea has a big problem. Let’s take a look.

I got a bunch of requests to comment on a new attempt at a theory of everything that supposedly combines quantum physics with general relativity. I had a look, and this is a quick comment. First reaction, basically. Didn’t get far in the paper, as you will see. I am sorry in case I appear unkind, but this kind of stuff really pisses me off.

Can Quantum Physics Explain Consciousness After All?

Check out my own course on Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.

Nobel Prize winner Roger Penrose famously believes that the collapse of the wave-function in quantum mechanics causes consciousness. A group of physicists now tries to improve on Penroses idea in a new paper. I have some comments…

Fermi Paradox Explained by Quantum Communication

Check out my quantum physics course on Brilliant! First 30 days are free and 20% off the annual premium subscription when you use our link ➜ https://brilliant.org/sabine.

The Fermi Paradox is an estimate that says: Given all we currently know about the universe, we should have found extraterrestrial life already. So why haven’t we? In a paper that just appeared two weeks ago, a physicist has now put forward the idea that aliens use quantum communication. How does that solve the Fermi Paradox? I’ve had a look.
