BLACK HOLE

BLACK HOLE is formed after the death of big stars. Basically, black hole are the things which have very strong gravitational force. It can also absorb the light. when a star get into its last few days then the fusion become less stronger than gravitation force in the star. Due to this in the core of star a black hole is produce in the core of star which absorb the energy of star or tar due to which star die before its death day. After then star goes through a blast and two most brighter rays called gamma rays travels in opposite direction which is the indication of bith of new black hole. There are billion of black hole in our universe which roam in whole universe.

ASSUMPTION- 1. black hole are the worm hole i.e. they are the door to travel in time.
                            2. Every galaxy has a super massive black hole in the centre. This assumption comes from that fact that only super massive black hole can drive thousand of star with the speed of thousand km per seecond to revolve in their orbit. And we have pics of centre of  our galaxy in which we can see thousands of stars revolving with great speed.
3. Black hole can be the door to the  new big bang.
4. We might be in a black hole . if it is so, then might be many universe.

Things we don't know-
                                    1. what is inside black hole ?
                                    2. how black hole work ?

CONFUSION- if there is a super massive black hole in the centre of every galaxy then it should suck the whole galaxy..........
