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

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

Billions of years ago the strength of the electromagnetic interaction was different at opposite ends of universe. That’s the surprising conclusion of a group of physicists in Australia, who have ...

For nearly half a century, theoretical physicists have made a series of discoveries that certain constants in fundamental physics seem extraordinarily fine-tuned to allow for the emergence of a ...

The idea that fundamental constants do not actually stay constant over space and time has long played on the mind of physicists. But by looking at how a distant galaxy has absorbed the light from a ...

One of physics’ most fundamental constants just got a little more constant. Physicists have placed the strictest limit yet on how much the fine structure constant — which determines how strongly ...
