Question

What is Black Whole and where is available and how can we make it? Can we travel to future by revolving around it? How can it destroy us if we come near it?

Answer 1

Very little information is known about black holes and most information and ideas on them are theories. It is theorized that black holes form upon the collapse of an exceptionally large star at the end of its life, and it continues to grow by engulfing other bodies of mass.  It is impossible as of this point in time at least to artificially create a black hole.
