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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

One of the most dissatisfying aspects of modern physics is the fundamental constants. It’s not that they are constant that bothers anyone, it is their very existence that is offensive to ...
