Metallic hydrogen created for the first time

It's a result that was predicted over 80 years ago by Eugene Wigner and Hillard Bell Huntington, two scientists who determined that at sufficient enough pressures it was possible to turn hydrogen in to a metal - something that was impossible to prove at the time."If this experiment is reproducible, it solves experimentally one of the major outstanding problems in all of physics," said Jeffrey McMahon from Washington State University.

The scientists behind the achievement now predict that metallic hydrogen, once created, may actually remain in either a solid or liquid state even at normal temperatures and pressures.

It is so dense in fact that it could even prove to be an effective replacement for rocket fuel.
