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, ...

Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for suitable atomic nucleus states had been ongoing worldwide. In 2024, ...

In sports and in cosmology, the rules of the game aren't supposed to change as you go along. Athletes call this playing fair. Cosmologists call it the cosmological principle, and it means that the ...

In physics, the Fine Structure Constant is one the strangest numbers. The Fine Structure Constant is one the strangest numbers in all of physics. It’s the job of physicists to worry about numbers, but ...

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 ...
