Antimatter Blackhole: What Would Happen?

In summary, the conversation discusses the possibility of creating a large amount of antimatter and using it to create an antimatter black hole. The question is raised of what would happen if this antimatter black hole merged with a regular black hole, and it is suggested that the result would depend on whether energy density is equivalent to mass in a volume. The concept of singularities and the potential for annihilation is also mentioned.

I know that we can only create small amounts of antimatter. But, suppose that we could create lots and lots of antimatter and we kept sending it into space to some empty place far away from our solar system. We keep sending antimatter to the same spot until the mass is enough for it to collapse into a black hole. So now we have an antimatter black hole. What would happen if this antimatter black hole merged with a regular black hole? Would they just merge or would they annihilate each other?

And when? Assuming you chuck two black holes together, on chocolate and one vanilla, remember they are just points in space. It is not inconcievable that if they came together on an intercept, but not head on collision where the distance between central points was less than the Schwartzchild radius of their combined masses they could co-rotate inside the larger black hole in some cosmic death spiral for some time before actually making contact. Perhaps millenia. We are talking about intersecting two theoretical points in space here.

So assume they meet at some point. (Not something I'm convinced can happen in any other than a theoretical sense) As they eat each other they release energy, most of which is retained inside the field but some of which leaks out.

The question I can't answer is "Is energy density in a volume equivalent to mass in the same volume?" If it is, then your matter/antimatter hole just converts to an energy black hole. If the answer is no, then as the energy goes up and the mass comes down the size of the hole dwindles and the energy escaping goes up to the point where as Hawking pointed out, small black holes explode releasing all their pent up mass as energy.

Anihilation takes time (not much time, but lore than zero). If singularities exist at all, they can't anihilate with one another. But if they could, none of the energy produced could escape, so mass inside the Event Horizon would remain unchanged. So the situation would be the same as two BH's made of ordinary matter merged.
 

1. What is antimatter and how is it different from regular matter?

Antimatter is a type of matter that is composed of antiparticles, which have the same mass as regular particles but opposite charges. When matter and antimatter come into contact, they annihilate each other, releasing a large amount of energy in the form of gamma rays.

2. How is an antimatter blackhole different from a regular blackhole?

An antimatter blackhole is a theoretical type of blackhole that would be composed of antimatter instead of regular matter. This would result in a reversal of the usual dynamics of a blackhole, with antimatter being pulled in by regular matter instead of the other way around.

3. What would happen if an antimatter blackhole came into contact with a regular blackhole?

If an antimatter blackhole and a regular blackhole were to collide, they would annihilate each other, releasing a tremendous amount of energy in the form of gamma rays. This would likely result in the formation of a larger blackhole, composed of both regular and antimatter.

4. Can antimatter blackholes actually exist?

While there is currently no evidence for the existence of antimatter blackholes, they are a possibility according to some theories. However, they would be incredibly rare and difficult to detect, as they would be indistinguishable from regular blackholes.

5. Could an antimatter blackhole be used as a source of energy?

While the annihilation of matter and antimatter does release a large amount of energy, it would not be a practical source of energy as it would require an equal amount of matter and antimatter to be created, which is currently not feasible with our technology. Additionally, containing and harnessing the energy of an antimatter blackhole would be extremely challenging and dangerous.
