Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

A striking reality faces modern cosmology: two of the most advanced telescopes ever built now agree on a result that the standard cosmological model cannot explain. Webb’s confirmation of the Hubble ...

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do.

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

ABSTRACT: A specific structure of Standard Model (SM) particles is proposed and investigated. According to this proposal, the precursor of an elementary particle is a de Sitter space tangent to ...

Physical artificial intelligence enables intelligent action in the physical world. This step towards making science fiction a reality requires a change in design engineering, says Thomas Andersen.

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...
