nothing
If you jumped into a black hole, you would be stretched into human spaghetti.
The black hole's mass would increase by an insignificant amount.
You would die
Should Earth ever collide with a black hole, it would get destroyed.
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
You would have a black hole the size of the combined mass of the two black holes.
You would die.
One does not simply "pass through" a black hole.
Gone.
Nothing, not even light, can escape a black hole. So Earth would get caught into the black hole's path and we would be sucked up and crushed to oblivion
No - should you fall into a black hole (which is very unlikely to happen), you would get ripped apart.
It would be torn apart by tidal forces as it approached the black hole. Once it crosses the event horizon id disappears into the black hole forever.
