THEORIES OF UNIVERSE

There are many theories on the existence of universe and how the universe will end and some of them are-

1. Big bang theory- This theory propose that universe had created by a single hot dense point called singularity that blast and from there time come in his existence. It had happened 13.8 billion year ago and after that element of hydrogen from helium. 



Today our universe is expanding much faster it is above our expectations. Scientists believe that the universe 

Started by big bang. Now scientists are trying to predict how the universe will end. 

Many scientists believe that our universe will end after 22billion year ago from now so now some of the scientists aren giving their theories that how the universe will be end. 

After the theory of relativity proved that our time is relative and it is not same in whole universe.. Many scientists proved the big bang theory they also proved that our universe will come to end.

Now we look on our some of the theories. 

1.Big freeze-It states that the universe will end due to frezze. It conversely know as heat deadth. This theory is mostly accquire during this freeze the universe in theory become so vast that gas would be spread and no new star will from and the universe will end. 

2.Big rip-The existence of universe is 13.8 billion year ago and that time expanding of the universe is very slow because their is strong gravitational pull but now there is low gravitational pull and more dark energy that helps in expanding universe. After some time the universe will expand to infinite and then the universe will ram up. This help to the ending of the universe. 

3.Big crunch-This theory propose that the universe is expanding but there is a point when the universe start to deform because gravity become dominat force.
