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.

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 ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...

Recent findings suggest that the fundamental constants may not be as stable as we assumed. The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, ...

Essential for life: this illustration shows how fundamental constants of nature set the fundamental lower limit for liquid viscosity. (Courtesy: thehackneycollective.com) The values of the fundamental ...

Flash Physics is our daily pick of the latest need-to-know developments from the global physics community selected by Physics World‘s team of editors and reporters In the balance: the kilogram can be ...

The fundamental constants that govern the laws of nature are being determined with increasing accuracy. A new paper outlines the proceedings from this year's Workshop on the Determination of the ...

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 ...
