WebMost physicists believe the universe was born in a big bang 13.8 billion years ago. In it, the energy making up everything in the cosmos we see today was squeezed inside an inconceivably small space – far tinier than a grain of sand, or even an atom. Then, this unimaginably hot and dense cauldron – for whatever reason – ballooned at a ... WebFirst; There is no such moment as 'before' the big bang. This is the moment when space-time was created. For us space-time is perceived as space and time but they are components of the same thing. So prior to inflation (expansion of space) there would have been no time! This makes it nonsensical to refer to a time before time began.
