>>12023372“solid” is correct here. Since you are arguing about the sun (I am assuming its core) consisting of metallic hydrogen, the differences between plasma and gas are secondary. I’m not that anon btw.
>how so?surface temp and neutrino emissions alone give a reasonable estimate about fusion processes. The measured values suggest fusion frequencies in the order of magnitude of plasmas present in densities of the sun’s core.
Reasonable explanations as to why plasma fits are high energies resulting from fusion. Lots of (kinetic) energy increases the chance of a fusion event and more importantly, strips electrons from molecules. The lower electrostatic repulsion of ions greatly increase the cross section as well.
It is valid to assume the high pressure would force Hydrogen into a metallic state. But the energies are just too high to allow that. It’s a feedback loop in a way.
On the other hand, if the core was metallic, there wouldn’t be a runaway fusion process, because the nuclear energy would be too low.
You could however argue for white and brown dwarfs to consist of a fraction of metallic hydrogen.
