In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

As given by Britain’s brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are: e, the charge of an electron; m, the mass of an electron (at rest); M, the ...

An ultraprecise new measurement has given some weird particle physics theories a black eye. By measuring one of nature’s most fundamental constants more precisely than before, scientists have tested ...

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, ...

The world’s measurement system will be based on updated values for four fundamental constants of nature. A revised SI ( the International System of Units ) based fully on accurate values of these ...

Some things never change. physicists call them the constants of nature. Such quantities as the velocity of light, c, Newton’s constant of gravitation, G, and the mass of the electron, m e, are assumed ...

If you’re confused by modern cosmology, you’re not alone. Cosmologists themselves are confused, and two new results, using very different methods, add to their collective bewilderment. The results are ...

Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years. Using known distances of 50 galaxies ...

In physics, there are a host of standard constants: the speed of light, the charge-to-mass ratio of the proton, and Planck's constant, to name just a few. Repeated measurements going back a few ...
