So, everyone knows the very supposed theory of BIG BANG after which universe has been expanding till date . But the question that arises is :
How the universe was before BIG BANG ? How vast is universe ?
How the universe was before BIG BANG ? How vast is universe ?
it was a tiny ball of energy and matter, all together, and the universe is still expanding
Yes, at the moment all the energy in the universe is spreading out forever but at one point it was all contained inside a small dot. At some point the edges of the universe will collapse and the implosion will collapse into a small highly dense ball again. The cycles involved take billions or trillions of years to happen. This is one theory, there may be many others.
