Red giant star is implodes in itself...Thats the mainly thing whats happening before but there is other else can come with this situation...
Whatever was in the spot in the sky that the black hole now occupies would no longer be there.
No one has been inside a black hole before and even if someone did they would probably die. So, no one knows what happens to the light going into a black hole.
That's not exactly what happens. What really happens is that they just absorb each other and become a bigger black hole.
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
It evaporates.

Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
They will merge to form a single black hole with the combined mass of the town that merged.
It gets bent toward the black hole's singularity.
Objects which approach a black hole will get sucked into it.
You die.
