How can you see the big bang and explosion around that location? We ‘Earth’ come from that place at a much slower speed. That big bang light passed us by! MrcWGroenlo

Answer

We’re not running away from the Big Bang at all, we’re standing where the Big Bang happened. Like everyone else. As has often been answered on this site, the big bang is an expansion of space itself. In the past, the space that now forms the visible universe was very small, so today it is so much bigger. Everyone stands still in relation to that space.

Where can we see the big bang? Certainly not here, because it happened 13.7 billion years ago, and the light from then is long gone, we now see the light from when the universe is 13.7 billion years old. We get closer and closer to the Big Bang the further we look. We don’t get there completely, because the earliest phases are blurred by the ionization of the matter, which then caused the radiation to constantly change direction. Due to the expansion of the universe, that older radiation also disappears to longer and longer wavelengths, and the big bang is the limit of infinite redshift, so the limit where we no longer get any energy. Due to the same expansion, the current distance of that information from 13.7 billion years ago is already about 40 billion light years away from us.

Now you naturally wonder how a universe of 13.7 billion years old can already be at least 40 billion light years in size. The answer is that the expansion of space is not subject to the condition that the speed of light is the greatest possible speed; that condition only applies to objects within that universe. It is widely believed that in the very early phases, expansion accelerated exponentially, so that the universe became very large quite early on.
