What we know is a drop.what we want to find is an ocean.this is the universe.
What is universe? What all it consist of?
Scientist are trying to enter the dark mystries of our universe still standing with some theories without proofs about it formation.
The earth the moon the sun and stars everything are part the universe and there are a lot of things which are still unknown to us. The universe is a complete mystery spreaded to unimaginable extent like we humans are unsignificant in the universe.
There are many theories regarding the formation of universe. But there are main three theories which explains the process.
1)The Big Bang Theory
Russian-american theoratical physict George Gamow and american cosmologist Ralph Asher Alpher were the founders of this theory. This theory states that Billions of years ago all particles in this universe like stars,sun consist a big sphere.As a result of a big bang this sphere was changed into stars
Planets and all other particles and all the elements are formed. This also states that nothing was created new and Universe always expand and it won’t come back into it’s original state
2)Super Steady Theory
This theory was developed by Austrian Astrophysist Thomas gold and Austrian-British mathamatician Herman Bondi.The Universe has no starting and there won’t be an ending.Universe is same as now Billion years ago and will be same after a Billion years ago though the asterism or group of stars separates from each other but it wont affect between them as new particles are formed constantly and new new starclusters are formed and matter is formed accordingly.
3)Pulsating Theory
This theory is developed by American astronomer Allen Sandage.This theory states that The universe expands and shrink. When shrinking the density increases and explodes and the particles move far away and when it reaches a certain point it is drawn back and rejoin due to gravitational force. Again they shrink and explodes. New particles aren’t formed. It only transform the particles. Due to the explotion billions of years ago the particles are moving far away and it will for many years.After that they will rejoin due to gravitational force
There a many more theories like
Eternal infalmmation theory and ossilating Universe which are the extenction or combing part of these theories.
These all just theories there are no sufficient proof for all these although we can’t look into the universe and see what’s happening.These theories are based on many known theories, concepts and mathamatical formula and some scientific based imagination.
But if look on all theories we can understand they all says directly or indirectly that the universe is expanding.
