Researchers built a laser that can supposedly run forever

June 23rd, 2022

Researchers have managed to create a never-ending laser they say can run forever. Unlike normal light-powered lasers, this laser draws its power from a special phase of matter. The researchers published their findings on the laser in the journal Nature earlier this month. We’ve seen a number of breakthroughs in lasers in recent years, including …

Mind-blowing physics experiment can turn matter invisible

November 24th, 2021

We finally have a demonstration of a quantum effect that was predicted years ago, which is capable of making invisible matter. Scientists at MIT have used lasers to squeeze lithium gas together after cooling it to very low temperatures. The result, though, is an invisible gas that can block the scattering of light. Scientists believe …
