A Brief History of Our Universe


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.

Stephen Hawking’s book, “A Brief History of Time” talks about the history of time until the Big Bang. And that is one reason why it is “A Brief history”.

The actual history of time goes way more beyond The Big Bang!

  1. So what do you think about the big bounce or the big collapse theory?Our Universe could be one in an infinite loop of successive big bangs and big bounces if not for the multiverse theory.

      • That’s true but there’s no observational or experimental proof of the multiverse theory too so the Big Crunch can be an another alternative to the multiverse theory

      • But multiverse is still far more feasible than the Big Crunch provided the rate of acceleration at which Universe is extending every second.
        And the rate of acceleration alone can be used to, both explain the existence of multiverse and completely deny that there will be a Big Crunch anytime soon.

      • The Big Crunch scenario hypothesized that the density of matter throughout the universe is sufficiently high that gravitational attraction will overcome the expansion which began with the Big Bang. The FLRW cosmology can predict whether the expansion will eventually stop based on the average energy density, Hubble parameter, and cosmological constant. If the metric expansion stopped, then contraction will inevitably follow, accelerating as time passes and finishing the universe in a kind of gravitational collapse.I too am a believer of the existence of a multiverse and a strong one too rather the Big Crunch which has been proven wrong to an extent,but it too has some validity so we cannot deny both of them until experimental data says otherwise.

      • We can deny Big Crunch for the moment.
        It won’t happen for a few billion years at least.
        Multiverse on the other hand. Well, it is just one theory away to be mathematically proven.

    • Well, that was what I wrote.
      Time is beyond our comprehension for now.
      Someday, we might be able to know for sure.
      Till then, it will remain an ever so exciting endeavour.
