There are many types of spacetime within physics, the same way there are infinite dimensions in math. Some spacetimes are ...

Raising the energy state of an atom's nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, ...

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, ...

In a new development that could help redefine the future of technology, a team of physicists has uncovered a fundamental insight into the upper limit of superconducting temperature. This research, ...

Through a variety of tests on Earth and throughout the universe, physicists have measured no changes in time or space for any of the fundamental constants of nature. When you purchase through links on ...
