If there is no black hole, then no Universe, we will not be exist. That's why there is a Big Bang. The Universe started off with a Big Bang from a black hole. Though if you want to know what happens before our Universe, then you need to study 'String Theory' and the 'M theory'.
well, we simply die.
As far as we know, the mass of the black-hole and it's energy would increase.
You cannot see a Blackhole with the naked eye and they're hard to detect anyway. No one would see a Blackhole pull anything into its center.
It sucks all matter within the event horizon. If one was created on Earth, the entire planet would be crushed to a singularity.
Simple. We die a brutal and painful death.
there is two syllables in thw word blackhole
If blackholes reach the earth the earth will destroy. Blackhole are to large it can eat star easily.
The Milky Way contains a supergiant blackhole at its center.
no
if two black holes collide, they swallow eachother making one giant blackhole
As you will not see blackholes on Earth, they may be in space. It depends on the blackhole, I am not an astronaut but I'm sure that all blackholes come in different shapes and sizes. But I do know that you would not like to get in one! cause of meep meep
no
