What is the event horizon?
Since no light can escape from a Black Hole beyond the Schwarchild radius, the Schwarzchild radius represents the limit up to which we can observe the events happening inside a Black Hole. Any event occurring within the Schwarzchild radius cannot be seen by an observer situated outside the Black Hole. Hence the boundary of the Black Hole denoted by the Schwarzchild radius is also called the event horizon of the Black Hole.
What is a mini Black Hole?
A mini Black Hole is one that has Shrink to a small size. The matter in it continues to be intensity dense as in normal black Hole.
What would happen if a mini Black Hole hits the Earth?
A mini Black Hole hitting the Earth would instantaneously punch a hole through the Earth and continue on its journey through space. The hole punched in the Earth by the mini Black Hole would close up immediately and any affected areas on the surface would be limited to the points of entry and exit of the mini black Hole. However, the mini Black Hole would pick up some matter from the Earth.
What would happen if a slowly moving mini Black Hole enters a very large body?
There is a possibility that a slowly moving mini Black Hole further slow down and even get trapped while passing through a very large body. In such a case, the mini Black Hole will continue to consume matter from its host body and grow, completely consuming the host body eventually.
Do Black Holes rotate on their axis like other heavenly bodies?
Yes.
