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, ...

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 ...

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 ...

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 ...

Images made with the W.M. Keck Observatory in Hawaii show how light from two distant galaxies is distorted into multiple images. UC Davis astronomers have made a new estimate of the Hubble Constant, ...

Through a variety of tests on Earth and throughout the universe, physicists have measured no changes in time or space for any of the fundamental constants of nature. When you purchase through links on ...

On human timescales, the universe may as well be eternal. It’ll be here long after our species and our planet are gone, but ...

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 ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. One promising avenue for this sort of study is a search for changes in ...
