The beginning of Time

One of the most confusing yet everlasting things in the universe is time. Time always moves in a straight line in the fabric of space-time as hypothesised and proved by Einstein. Time unifies all the fundamental quantities of the universe and is an essential part in inventing the theory of everything.

"Time is what prevents everything from happening at once"-- Albert Einstein

But the main question is, at what point on the past, did time begin?. Did it begin before the big bang or after the big bang.

If the one dimensional quantity that is time kept on unweaving after the big bang, what happened before it?. After the observations from Hubble space telescope we came to a conclusion that the universe is expanding. According to Einstein's theory of relativity, we can  understand that space and time are not seperate but are woven into each other. Space-time( 4 dimensional representation) is explained in the theory of relativity. As space is expanding time is also relative to it, so it time keeps on moving forward rather than backward(this is explained by our current physical laws, we don't know what would happen in the future yet!). From the observations of Hubble telescope universe is expanding, that implies that universe at some point,was all together held by strong gravitational forces which was infestimally small in size but possess infinite gravity. Then this mass collapsed leading to a huge explosion called Big bang which resulted in the birth of our universe.

But note that The Big bang is just a hypothesis by the scientists.

Enough of all these, but The origins of Time is still unknown to the current understanding of the knowledge in physics and mathematics. But one thing we know for sure is that, time will continue to exist forever. We cannot feel it nor touch it or measure it, but it exists with us and continues to change forever and ever. Time is the fundamental quantity in the whole universe but is not constant everywhere. It is Relative to the observer. Understanding the concept of time brings us closer to unifying all the partial theories and creating The theory of everything  just as dreamt by our brilliant human sir Stephen Hawking.
