And here we go for the a better chemical rocketttt.
Really though, amazing find there.

But it needs to be either very cold or under high pressure, so not very practical.

I'm a little skeptical of it being metastable. Even if it is, I'd be worried about exactly how stable it could actually be. A room-temperature superconductor that explodes if you sneeze on it is not exactly useful.
Nonetheless, this is incredibly exciting. Not in the least because pellet-fed metallic hydrogen rockets would combine a remarkably energy-dense fuel with an outlandishly light and high-velocity exhaust.

May = they have yet to disprove it. Going to let the researchers do a bit more before I will remotely take this seriously. |

Besides propellant, metastable (at STP) metallic hydrogen would have a huge impact as a room temperature superconductor.
Also, might it enable pure fusion bombs? Miniature ICBMs with much smaller, pure fusion warheads? That would be pretty interesting...

Going to let the researchers do a bit more before I will remotely take this seriously. It isn't just the one article on a popsci website, metastable metallic hydrogen has been predicted for a while. But yeah, I'll eat my hat if it turns out to be true just because it would be so amazingly useful in so many ways. The universe is too cruel for that  I guess time will tell! |

Considering the sheer dearth of references to meta-stable metallic hydrogen in scientific literature, I'm pretty sure it's not a thing.

Miniature ICBMs with much smaller, pure fusion warheads? That would be pretty interesting... It would enable a lot of things... If it did. We aren't even sure we've managed to make the stuff. From what I hear metallic hydrogen will also pay all your loans and make your wife love you again. |
