Researchers find evidence for metallic hydrogen

Researchers long ago theorized that if hydrogen gas were exposed to enough pressure, it would transition into a metal. Recent results indicate that hydrogen does become a solid at 425 gigapascals.

It's real: Metallic hydrogen has been created for the first time

More than 80 years after it was first predicted, physicists have created metallic hydrogen - a mysterious form of hydrogen that could be capable of superconducting electricity without resistance at room temperature.
