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, ...

By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have ...

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 ...

An analysis of the jumps of a hydrogen atom’s electron has yielded a new, precise value for the Rydberg constant, a fundamental quantity in physics 1. The Rydberg constant is related to hydrogen’s ...

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 ...

Do scientists need to re-examine the basic model of the universe? Using new measurements of cosmic distances, astronomers have refined their calculation of the Hubble Constant, a number that describes ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...
