How our universe took birth?

How our universe took birth?

Man has always wondered how the universe originated. a number of duties have been put forward to explain its origin.

According to the Big Bang Theory, the universe is the result of an explosion call Big Bang. This explosion occurred about 14 billion years ago. When the Big Bang happened it let loose a huge amount of energy.This energy keep the universe expanding this expansion is likely to continue for another 50 Billion years .Some other scientist who propagate the steady state theory, believe that the universe has no beginning or no end.

Big Bang Theory.

The Big Bang Theory state that, the universe was once a smaller than atom. This  tightly particle exploded, and from it came over the material of which the universe is made.

Once  the big bang occurred, the universe start stretching like the rubber skin of a huge balloon. space and time begin to expand at an incredible rate. this phenomenon is called space inflation .At the end of the Rapid inflation the universe became cooler, the   particles that make up matter begin to fall out of some energy.

The gas and dust formed after the explosion contest in the galaxies that a speeding away from each other.

Actually before the Big Bang there was nothing, no time, no space ,only a tightly packed particle which we can call a singularity  , it had all the Mass that nowadays Universe has, we do not know anything about that singularity the only thing that we know is nothing.

The Steady State Theory

Although most scientist agree that universe begin with the big bang, there was some who disagreed. the British scientist fred hoyle, Harmann bondi and Thomas gold, in 1948, put forward the steady state theory.

According to  the steady state theory, the universe is  uniform throughout both time and space, and had no beginning. Since this theory had no answer to many phenomena found in the universe, it  gradually lost its spotters and remained just theory.

In brief,

 In the steady state model, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle, a principle that asserts that the observable universe is basically the same at any time as well as at any place.
