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, ...
As fundamental constants go, the speed of light, c, enjoys all the fame. Yet c’s numerical value says nothing about nature; it differs depending on whether it’s measured in meters per second or miles ...
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 ...
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, ...
