A question regarding this.....
If solid-metallic hydrogen IS constructed...is it then stable under various
conditions? That is....could it exist at "room temp/pressure"....or would
it require the horrendous pressures of a gas giant ?
Regarding planetary energy production. Let's see if i got this right.
Earth has a liquid core....the REASON it does is that it has a large
moon....the moon acts as a brake on earths rotation which causes
heat....(that plus radioactive decay)...this heats up the core and provides
for all kindsa cool things like continental plates and probably life...
Is that right?
