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

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, ...

A researcher at the Department of Physics at Tohoku University has uncovered a surprising quantum phenomenon hidden inside ordinary crystals: the strength of interactions between electrons and lattice ...

Even on a black hole’s turf, an essential constant of nature holds steady. According to standard physics, the fine-structure constant, which governs interactions of electrically charged particles, is ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

In 1999, a paper in the prestigious scientific journal Physical Review Letters indicated that one of nature's fundamental constants -- a number that, in effect, reflects how tightly atomic particles ...

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