Whatever was in the spot in the sky that the black hole now occupies would no longer be there.
Red giant star is implodes in itself...Thats the mainly thing whats happening before but there is other else can come with this situation...
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
That's not exactly what happens. What really happens is that they just absorb each other and become a bigger black hole.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
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.
Light that enters a black hole cannot escape due to the immense gravitational pull, resulting in the light being trapped within the event horizon and unable to be observed from the outside. It is thought to contribute to increasing the black hole's mass.
Objects which approach a black hole will get sucked into it.
It gets bent toward the black hole's singularity.
