[Physics] Quarks falling in a black hole

black-holesquarks

All I know about quarks is that they make up protons and neutrons and you can't really pull a quark pair apart, you just end up with 2 quark pairs because of all the energy you added becomes 2 new quarks.

All I know about black holes is objects falling into them are pulled apart by tidal forces as the gravity at the close end is stronger than at the far end of the object. Eventually matter is pulled into individual atoms.

So I was thinking about what happens when a quark pair falls into a black hole. Quarks have mass, so they should be affected by gravity and get pulled in. If quark pairs can be spaghettified, at some point they will pull apart generating two quark pairs instead of one. If this process were allowed to continue you'd have infinite quarks.

This is where I think I've made an error. If black holes could make infinite quarks, their mass should increase over time as gravitational energy is converted into new quarks. This extra mass should increase the black hole's gravitational force, increasing its ability to pull new matter in and to split quark pairs. If this were true black holes could gain mass even without absorbing new matter. These seem like blatant violations of conservation of mass and energy, but I don't know enough about advanced physics to figure out where I went wrong. I was hoping someone here could tell me.

Best Answer

I would imagine that, the energy that pulls the quark pair into the black hole is intrinsic energy (ie it comes from the black hole), and the quarks created through 'spaghettification' would only be proportional to that energy pulling on them. Therefore, seeing as energy is equal to mass and vice versa this new mass would not be created, rather transformed from the energy of the black hole. The black hole never gains more mass/energy than the original quark pair because it already contained the mass/energy in its system that would be then created into more quark pairs. I hope that makes sense
