The Big Bang What Caused ?
The Big Bang What Caused ? : For almost one hundred years, we have known that the universe is expanding. We have traced this expansion back in time, through to the very beginning when the universe occupied an infinitesimal point in space. This was the state of the universe at time t=0, over 13 billion years ago.
It is from this starting point that everything we are familiar with came into existence: protons, neutrons, stars, galaxies – even space and time itself are here. At time t=0, this point began an unprecedented inflation, in this instant time and space were born. This event has become known as the Big Bang.
