Physicists have a lot of questions about our universe. Here’s one more to add to the list: Why is it so asymmetrical? New research has confirmed an anomaly named the Hemispherical Power Asymmetry, which states that the cosmic microwave background has more fluctuations in one side of the universe than the other. The weirdest part about this is that no one even has a theory for why this might be the case.

Up until last week, physicists believed that matter is made up of only two types of particles: those whose spin has full-integer values (bosons) and those whose spin comes has half-integer values (fermions). But in a new paper, a group of researchers turned the world of physics upside down by mathematically proving that a third type of particles – the “paraparticles” are possible.

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.

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.

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.

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.

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.
