Modern science

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 fre

Today we are going to discuss about bootstrap paradox. This paradox shows that the flow of the time is linear and we can't change the things happen in the past. If we can then we will trap at an endless loop form that paradox we can coclude that we can only travel in future not in  past with the help of time machine.  lets understand this with the help of example that will clear  your concept. For eg-Tom is a scientist and with his hardwork he make a time machine. He is big fan of Stephen Hawking. And he also want to do some argument on black hole with Stephen Hawking. so he want to go in in past  with the help of his time machine.With the reference he takes Stephen Hawking book about black hole. Then with the help of  time he goes in  1965  when Stephen Hawking was studying about something else. When he met Stephen Hawking and tell him about black hole. Stephen Hawking refused to believe in black hole existence. Then  tom became angry  and  come to present.
