This is going to sound absurd, because it probably is, but what would happen if someone shot antimatter into the core of a black hole or some other gravitational singularity? Since antimatter is the polar opposite of matter, I wonder how much different the result would be from matter coming into contact with that same black hole? I know this is entering the realm of the theoretical, but none the less, I’d like to hear your thoughts on the subject
The black hole would absorb the antimatter like it would anything else.
Matter and antimatter are annihilated and converted to pure energy when equal masses of each are slammed into each other. This energy release cannot escape the event horizon of the black hole so the result of someone shooting antimatter into a black hole would be entirely unremarkable.
There is only one result for throwing anything into a black hole's event horizon: the black hole absorbs it and becomes bigger.
