Some stars, comets, stardust, moons, planets, have been "eaten" by a black hole. None know for sure how many of each.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
It is possible but extremely unlikely.
Its mass. All the stuff it has swallowed.
Well we'd all die
There already are black holes.
If the Earth magically became a black hole, the moon and other satellites in orbit around Earth, would be literally ripped apart into tiny bits and swallowed by the black hole.
The Black Hole will explode because the gravity of a Black Hole is formed by the matter that is in the process of going intothe Black Hole, and not that matter that has already gone inside.
There are already black holes within the universe
i believe the black hole crushes the object into another small black hole which just ads to the already infinate space within
...no if there was we would all be died already
No one has "seen a black hole" but evidence of where a black hole must be has been observed.
No. Tomorrow has been and gone and no black hole has appeared.
