Where had the Big Bang happened? Where is the center of the universe?

One of the most talked-about theories of physics is the Big Bang Theory. It is said to have happened

about 1400 years ago, and advocates of the theory present arguments that, initially, the universe was no
more than a tiny dot. The birth of the world, as we see it now, is what is termed as The Big Bang – the
great explosion that gifted us this world.

Now, as every story has two sides, this theory also has numerous explanations and misconceptions.
Firstly, not all the proponents of Big Bang Theory suggest that the Big Bang was an explosion per se.
They ascertain that Big Bang was the nature expanding in every possible way.

Notice how it is the word expanding that is used to explain and not to explode? Yes, that’s the catch. For
the people claiming that the Big Bang was an explosion, it gets super difficult to explain the next
question about the center of the universe.

The other side of the story holds the fort of Big Bang not happening at all. This is where further
explanation comes in. There is no center of the universe because the universe did not originate from a
“bang.” The ones not believing in the Big Bang argue that since instead of exploding like a bomb, the
universe expanded like a balloon, the Big Bang cannot be termed as the birth of the Earth.
Explosion and expansion are two different cases. In an explosion, the particles burst outward from
where its center is, and a person standing in the way would see them coming toward him. But it is not so
in case of expansion.

If you want to get it clear in your head, then consider typical examples of pure natural and experimental
explosions. The supernova is an explosion, a bomb going off is an explosion, the gamma-ray burst is an
explosion, but the Big Bang is not. In an explosion, a center is clearly visible, and it remains visible even
after the explosion. So, there is no plausible explanation that could call Big Bang an explosion that
resulted in the might Earth.

One of the widely used analogies to help explain how the world cannot have a specific center from
where it started is the balloon analogy.

If we take an example of a dotted balloon in the context of the universe, then as the balloon expands
gradually, no dot nears the other one. Implying that they are not coming together; rather, all the dots
are moving away from one another. The balloon is expanding, and hence, it cannot have a focal point or
a center where all the dots originated from. Rather, the dots were smaller in size and present at their
designated places.

Looking at the universe as such a balloon, it can be said that the Big Bang did not happen at some
certain place, but everywhere. Hence, when seen from the Earth, as it is, the Earth seems to be the
center of the all expanding universe.

Moreover, if the Big Bang had happened in one place, then the world would not be divided into regions
with balance. In an explosion, the things with high velocity and speed end up getting dropped the

farthest, while the lighter things tend to get dropped off nearby. However, this is not the case with our

This analogy further emphasizes that the Big Bang did not happen at one specific place, especially at the
center of the Earth. The birth of our Earth is rather better explained by the theory that the Big Bang
happened everywhere – all the things expanded and grew into their larger versions we see now.
Therefore, the Big Bang did happen but not in one place or a specific region – it happened
simultaneously throughout the lands.
