Why big bang is the most relevant theory of formation of universe ?

By Umang Rajpurohit

There are some unanswered mysteries which everyone is excited about like the black matter, black hole and the dark things. But one such mystery which is almost every person is very keen to know is how our universe formed ? what was before the formation of universe ? who created the universe ? is the universe created by the so called god ? what was there before anything ? and many questions.

It is not such that nobody has tried to solve this mystery or nobody has attempted this question. But even after so much attempts and so much research we are not sure about those theories given by the scientists or mathematicians. But let's first talk about the theories and hypothesis given by some well known scientists and mathematicians.

The very first and one of the most well known is the redshift theory or doppler redshift theory, which talks about the wavelength(which eventually solves the universe formation mystery, not really). 

Other is the steady state theory which is based on the idea that the universe is expanding but it is also maintaining constant average density. There is also a theory which is accepted by religious people which is the creationism, which supports the idea that the god created the universe(although this theory didn't give evidence as how god created the universe and hence therefore this theory is negated because the very step by which science find the answer is evidence and creationism is unsuccesful in giving the evidence).

But the most relevant and acceptable is one and only big bang theory(most reasearched about and approved by most profound astrophysicists). It gives a accurate timeline like when the first atom formation to the time when our solar system formed.

 

So, according to big bang around 13.8 billion years ago, our universe was just a size of a tiny ball and as the pressure increased, the ball exploded at a enormous boom and all the material the tiny ball got scattered and resulted in the formation of our universe.

Sounds simple! But the big bang is not that easy to understand as it may sound and it's pretty complex. As you know the universe is not a tiny ball but it is large(as large as anything). To put it in simple words it is the basis of the universe, with a very less error, still many physicists doesn't believe in the idea of big bang. According to them, the big bang is a lame idea because it does not include the very first law of thermodynamics which say that the energy can neither be created nor it can be destroyed. 

But now you will say then how we can say that it is the most relevant one. If we look at all the other claims of the formation, big bang stands apart because it provides answer to most questions related to the formation of universe. As the big bang suggests that there is beginning to the universe.

I hope that was useful, this was the research from my side, there are chances you will find some mistakes or you may disagree with some ideas and that is completely ok!
