Answer 1

A Black Hole is a area of such immense gravity that nothing-not even light can't escape from it . black holes form at the end of some stars'.the energy that held the stars together disappears and it collapses in on itself producing a magnificent explosion. black holes can form in many ways though and large black holes can have tens to millions of times the mass our sun  trapped in a point smaller then the tip of a pin! some black holes trap materials more and more as their mass increases . the point where all these mass is trapped is called singularity it may be infinitely small but its influence is enormous
