THE BLACK HOLE

HUMAN BRAIN HAS ALWAYS ASSUMED OR PREDICTED ANYTHING FIRST, AND THEN PROVED ITS EXISTENCE. BLACK HOLE WAS ONE OF THESE BUT NOW IT IS A REALITY. ITS PREDICTION WAS DONE BY THE GREATEST OF ALL TIME ' SIR. ALBERT EINSTEIN ' IN 1916 BY HIS THEORIES OF RELATIVITY ( WHICH I WILL WRITE IN MY NEXT BLOG ). 

INTRODUCTION:-

                                   As I have told you earlier that black holes were first predicted by SIR ALBERT EINSTEIN, but he did not found it and neither he coined the term 'black hole'. Black hole was founded by SIR KARL SCHWARZSCHILD in 1916 and the term was coined by SIR JOHN WHEELER in 1967.

   THE FOLLOWING ARE THE IMAGES OF THESE GREAT PERSONALITIES

SIR KARL SCHWARZSCHILD

SIR JOHN A. WHEELER

' A black hole is a region in spacetime where the gravitational pull is so strong that even light cannot escape it.' The general theory of relativity explains it existence. 

                                                        

FORMATION OF A BLACK HOLE:-

                                                              Now here I would like to draw your attention to my previous blog on ' SUPERNOVA ' , where I had mentioned that a supernova explosion might create a black hole and it is the only theory till now which explains the formation of a black hole.

OTHER THEORIES RELATED TO BLACK HOLE:-

1. SAVIOUR OF PLANETS:-                                                                                                                                                                                                 As we all know that stellar objects do not remain stationary, they move around in the universe, even the solar system moves at an speed of 200 kms/sec. So how can a potential supernova remain stationary and hence it also moves around in the universe. Now these supernovas might blast anywhere in the universe, but here comes the black hole. Many of the supernovas actually encounter the black holes and they are pulled in by the gravity.                                     
2. TIME TRAVEL:-                                                                                                                                                                                                       Time travel is the most curious topic and everyone is waiting for answers of their queries. Now there is a theory in this world which states that black holes might act as time travel vehicles.                                                                                                                                                                       
3.  SPACE TRAVEL THEORY:-                                                                                                                                                                                                              Travelling in space is not easy, since the universe is very big. Its enormity can easily be understood by knowing that distance, in universe, is measured in light years just like we treat kilometers and miles on Earth.                                                                                                                                                                                                       Now we know that everything in this universe has an ending so a general question arises where would black holes end or where will its second opening be ?? And here we have two theories or assumptions. First one says that black holes might connect two very different parts of the universe and it might help us in rapid travel around the universe.                                                                                                                                                                                                    Second one says that black holes might act as worm holes i.e. they might act as connectors between two different parallel universes.
