One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...

A fundamental constant of the universe may not be so constant after all, according to a new study. Recent observations of distant galaxies suggest that the strength of the electromagnetic force the so ...
