Pretty sure they are not protons anymore once something is inside it.

The positive charge would remain though

[โ€“] MrFunnyMoustache@lemmy.ml 2 points 1 year ago (1 children)

Is that so? I assumed that a small black hole would rip apart a proton through spaghettification, therefore it won't have two up quarks and one down quark. But even if the charge remains, such information can't escape therefore its electric charge won't influence the universe.

I might need to read up more on this.

[โ€“] davidgro@lemmy.world 3 points 1 year ago (1 children)

Yup, there's a theorem ("no-hair theorem") that the only information about a black hole which does influence the universe is its mass, spin, and electric charge.

Oh, I stand corrected.

[โ€“] luthis@lemmy.nz 2 points 1 year ago

You may be right, but I have yet to have evidence to the contrary.
