For decades, it was assumed that the expansion of the universe was accelerating—a theory that won the Nobel Prize. Now, ...

From Fundamental Concepts to Dynamical Mechanisms, by Wolfgang Bietenholz and Uwe-Jens Wiese, Cambridge University Press.

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

Could reality be made of more dimensions than those we perceive? The question has consumed some of the most brilliant physics ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Ian G. McCarthy receives funding from UKRI's Science and Technology Facilities Council (STFC). He works for Liverpool John Moores University. Given how unfathomably large the universe is, it is ...
