Our universe, which consists of stars, planets and galaxies, did not once exist. Then a mysterious event gave birth to everything, the Big Bang, but what was there before that? This question has remained a challenge for scientists for centuries. Did the universe begin from a singularity, or did it exist somewhere before? Some theories even suggest the possibility of a multiverse. Today we will understand in simple language what the Big Bang was, what was before it, and how it became the beginning of the entire cosmic journey.

What is Big Bang?

The question of the origin of our universe has always fascinated the human mind. About 13.8 billion years ago, an event occurred which we call the Big Bang. It started from an extremely small, hot and extremely dense point, which scientists call a singularity. From this point time, space and matter were born.

The Big Bang was like an explosion, which started the universe expanding. In the early moments, only tiny particles, such as quarks and gluons, existed. As the universe expanded, these particles started turning into atoms and eventually stars, planets and galaxies came into existence.

What was there before the Big Bang?

Now the question arises that what was there before the Big Bang? Many theories have emerged on this.

singular state theory

Scientists believe that before the Big Bang, the universe was in a singular state. This was the state where all physical laws fail. There was no time, no space, only a point of extreme density.

Cyclic Universe Theory

Another idea is that the universe has been expanding and contracting cyclically. It can be thought of like a balloon, which is inflated and released again and again. After the previous universe contracted, a new Big Bang began.

multiverse theory

This theory tells us that our universe is not alone. Countless universes may exist, each with their own rules and time. Our Big Bang may just be an event that happened somewhere else.

Why did the Big Bang happen?

The answer to this question still remains a challenge for science. Some scientists believe that quantum fluctuations started this process. Small changes of energy took place in empty space, due to which particles and anti-particles were born.

What is cosmic inflation?

Immediately after the Big Bang, the universe expanded extremely rapidly. This is called cosmic inflation. This made the universe uniform and smooth. However, why and how this expansion started remains a mystery even today.
