Actually, this is new! This particular breakthrough has a different molecular structure than what was found back in October, and the way it's been configured is different.
Scientists first need to see if it's stable at room temp, and that should take a few months. After that, it'll be up to how quickly it can be reproduced.
For 80 years, scientists have been trying to figure out how to produce metallic hydrogen. The search is finally over, and this breakthrough is going to transform everything from space travel to how we turn lights on and off.
