Since its formation in 1956, the Big Bang Theory has acquired a lot of support from cosmologists. Even today, it continues to explain most of the known facts about the origin and evolution of the universe. But, it still faces certain behavioral problems. The theory is based on two main premises – the first being that of cosmic inflation and the second being that once there was a singularity which broke down into subatomic particles and finally stars, galaxies and all other kinds of celestial bodies. If this theory is correct, then there should definitely be tell-tale signs like radiation pockets that confirm it.
Big Bang Theory has been receiving a lot of attention from all quarters.
Big Bang Theory has been receiving a lot of attention from all quarters. Theorists have been trying to resolve the issues with Big Bang Theory and as a result, a number of new theories have cropped up. The most notable among them is Steady State Theory.
The main difference between Big Bang Theory and Steady State Theory is that the former theory states that the universe was created at one point in time, while the latter states that the universe has no beginning or end.
The Big Bang Theory suggests that when an object travels faster than the speed of light, it shrinks in length and increases in mass. This is called length contraction (similar to Lorentz-Fitzgerald contraction). So, if it were to travel at speeds approaching infinity, it would shrink to a single point. All matter was concentrated at this single point which exploded with immense force creating the universe that we live in today.
There are two major problems with this theory:
The first problem is with how matter was concentrated at a single point. It is impossible for any amount of matter to be concentrated at such a small space as there would be immense gravitational pull which would prevent any matter from being added into this space. Even if matter did manage to get there, scientists have determined
It is the main theory to explain how the universe came into being.
It offers an explanation for the origin of the galaxies, stars and other heavenly bodies. It explains that the universe started as a singularity that exploded and resulted in everything else including time and space.
There are two points of view in relation to Big Bang Theory – those that think it is a valid scientific theory and those that do not think so.
Merits And Demerits As A Scientific Theory
The Big Bang theory is an attempt to explain the existence of our universe. According to the theory, what we see today as the universe was initially a single point that exploded, releasing all of the energy and matter that exists today.
If you are looking for a scientific perspective on the big bang theory, then this article is for you. We have highlighted the merits and demerits associated with this hypothesis.
Merits:
It was one of its kind. It was the first ever theory that explained how our universe came into existence.
The Hubble law, the cosmic background radiation at 2.7 degree Kelvin and other evidences give light to this theory.
The idea that all matter originated from extremely hot, dense conditions fits in well with many observations about black holes and other phenomena at the center of galaxies.
Demerits:
This theory does not explain how did that singularity come into existence?
The singularity was an infinitesimally small point in space-time, where all laws of science were broken. So it is not possible for us to apply any physical principle because when such a thing happened there were no physical laws yet!
The merits and demerits of big bang theory may always be debated but fact remains that it gives us an insight on what might have happened when the universe came into existence.
There are many merits and demerits of the Big Bang theory. Big bang undoubted gives an account of the beginning of universe and event after an initial explosion of singularity. It is considered as one of best theory compared to any other theory in this respect. The Big Bang theory is the one which provides a picture of natural world and which allows scientist to predict many phenomenon. Therefore it can be seen as one of the most successful scientific theories till date despite its demerits because due to its success it has been able to survive all criticisms, this highlights how strong the support for it is.
