The Expansion and Contraction of Universe

Ever since the modern times from 18th century till now we have known that the earth is a planet and the sun is a star and the earth revolves around the sun. The fate of the earth is that it will be destroyed some day in the future by the sun and that will be the end of everything. But the biggest question arises is that what after that? what about the next life? Einstein has said that energy can neither be created nor destroyed then what will happen to all the energy presently available on the earth?

I have tried to find out the answer to these questions by myself. These questions makes me restless so I have tried my best to get the answer. The fact is that our sun is half its age at present. so exactly after another half of its age it will start loosing its energy (hydrogen) and will continue to grow in size because the energy which is keeping its particles bound together will all be used up. Then it will start absorbing all its planet one by one and our earth is one among them. That time we call it as apocalypse or end of the world. The earth will be crushed into ashes and all its particles withered away inside the huge sun. slowly our solar system will just be a ball of fire .

After that the ball of fire will continue to burn until all its remaining energy is used up and finally destroying itself. Now the contraction process of our solar system will start . It will happen just like a balloon when the air inside it is released. At the same time all other stars and planets in the universe will undergo same fate one by one. Finally they all will merge and Continue to shrink until they become Singularity !! Now what is this singularity?? This  is nothing but a Black hole as coined by Sir Stephen Hawking. The black hole has infinite gravity and nothing can escape out of it. So This will be the end of contraction process with everything around us converting into nothing but a particle called black hole.

Still this is not the end of everything !! when I was a child I learned this quote in school that "End is the new Beginning". The same proverb applies here. Now lets go back to the beginning of the universe. The first thing which comes to our mind is "BIG BANG". How did the big bang start?? From a particle ! Right! This theory has even been proved in Hadron collider in 2012. So Now since our universe will get shrinked to a particle or singularity, again a Big Bang will take place and once again there will be a formation of a totally new universe with new features may be. we have no Idea what this universe will be like but one thing is sure that the universe will be reborn , with or without humans.

Whatever is present now is bound to get destroyed some day and reborn some day.civilizations will take place and withered away by the waves of time. Life is a circle of events. Nature will continue to do its part according to the law prescribed by the almighty.  It is simply beyond human control.
