Thread: The relationship between anti-matter and Black holes

Is anti-matter were to collide with a black hole (Super massive of star scale) what would happen to the black hole. Will it compromise the structure of the black hole or its gravitational field? What would happen if an ball of Anti-matter the same size, density and mass as a black hole where to collide with a black hole? I understand it would produce massive amounts of energy, but what would happen to the black hole?

From what little I know of the subject, the black hole would grow just the same as if it had consumed the same amount of matter. The matter and antimatter may annihilate (or may not; it's debatable whether a black hole is made of matter in the same sense), but the energy would remain trapped. Due to mass-energy equivalence, the result would be the same.

Of course, that's assuming that the antimatter actually got past the event horizon. There's usually a lot of matter caught in orbits in that area.

I think that the black hole would simply become larger, but Im not sure. If there were any matter nearby, or if the black hole was partially composed of some type of matter, then the hole would go "KABOOM!" or in other words simple annihilate itself. I would also assume that the magnetic field surrounding it would be affected because the magnetic lines of force would be cutting through the anti-matter. Im not sure, but wouldnt this create some form of an electrical current? It is anti-matter, and has different qualifications than matter, but it still is a subject that contains particles of some sort. Perhaps scientists will even discover that black holes contain elements of a permanet magnet-due to its constant motion, and find that the anti-matter has similar components of a iron core with turns around it. Perhaps you have discovered the cause of a giant Electro-magnet! But- its just a theory, and highly unlikely.

Nothing would happen. It would just become more dense, and to prove this, look up Hawking Radiation. Antipartners are always falling into black holes but the positive matter escapes. This is the Hawking Radiation.

Hawking Radiation is merely a theory, that is why he never got the Nobel Prize.

Quite right, but i would rather see it as a hypothesis, since we have never directly observed a black hole.

Yes, Manynames, but the point of the matter is that antipartners in Hawking radiation are virtual. We're talking about real antiparticles here.

Doesn't change my opinion. I feel nothing would happen.

The particles and anti-particles inside may very well annihilate, but since photons cannot escape a black hole's gravitational pull, the energy does not escape.

My thought is that matter and andimatter are constantly being produced and annihilated inside a black hole, as the energy is unable to escape.

I doubt that would happen, but only ''now and again''. The reason why is because as soon as something enters a black hole, it continues to move into it's well (as in a water well) just as much as their paths are now moving as fast as the speed of light towards the singular point located in its center. Before they even get a chance to communicate they would almost certainly either ''tunnel'' or ''wormhole'' out of the black hole, or they are just the same products that are bound to be dreaded to be blown out of proportion in the infinite integrals of the singularity.

I don't buy into theories about tunneling, or wormholes, but OK.

It would need to happen however, or we are left with what is called;

The Information Paradox

I believe there are other resolutions to the information paradox besides wormholes. The one I've heard of most often has the information from anything falling into the black hole smeared across the event horizon.

This assumes time exists in some measurable form, and that this branch of quantum mechanics is correct. Which I am not convinced it is.
