People often misunderstand The Big Bang. People think that Big Bang was the beginning of everything. No! It wasn’t.
Big Bang was merely the beginning of our Universe. It was an event in our history that laid the foundation of the Universe we live in today. But it doesn’t mean that there was nothing before the Big Bang happened.
Assuming there are millions and billions of Universes just like ours, some young and some old, it means that many of them have been present much before ours came into existence. And some came into existence much later after the Big Bang that burst this Universe into form.
Big Bang is where our Universe began. Not where Time began. Time goes much more beyond what we can even imagine.
Theoretically, there might have been millions and billions of Big Bangs just like ours leading to the birth of countless number of Universes all across the Multi-verse.
Theoretically, time has existed for a period beyond our imagination.
Not beyond what we can think but beyond what we can accept. We have developed, evolved and have learnt a lot about the Universe and its workings, but we are still limited. There still comes a point where we stop ourselves from accepting what we are able to imagine.
The actual history of time goes way more beyond The Big Bang!
