In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Thorium atomic ...

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, ...

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 ...

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 ...

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, ...
