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, ...

Cells have always hummed with activity. They make their own energy, package it into molecules like ATP, and spend it ...

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, ...

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 ...

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 ...

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 ...

Learn how tension and friction interact when an object moves at constant velocity. This video breaks down the force balance, explains why acceleration is zero, and shows how physics principles apply ...

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 ...
