"space is just an empty void until you fill it with your own imagination"

                                 -Dhruv Sachdeva

let's start with some fundamental questions like what is the universe?  How it was created? and how old is it?

The universe is a collection of stars, galaxies, planets, clusters, and other astronomical objects. with no particular starting or ending point.

The idea that the universe was suddenly born and is not infinite was quite famous Up to the middle of the 20th century, most scientists thought of the universe as infinite and ageless.

Until Einstein’s theory of relativity gave us a better understanding of gravity,

and Edwin Hubble discovered that galaxies are moving apart from one another

in a way that fits previous predictions.

 

In 1964, by accident, cosmic background radiation was discovered, a relic of the early universe, 

which, together with other observational evidence, made the Big Bang

Since then, improved technology like the Hubble telescope

has given us a pretty good picture of the Big Bang and the structure of the cosmos.

Recent observations even seem to suggest that the expansion of the universe

is accelerating.

But how did this Big Bang work?

How can something come from nothing?

Let’s explore what we know.

We can ignore the beginning part for now.

First of all, the Big Bang was not an explosion.

It was the beginning of everything.
