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 ...

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 ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

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 ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.
