Where did the Big Bang happen

The universe originated almost 14 billion years ago during what we call the “Big Bang”. But where exactly did the Big Bang happen?

No space or time

It’s a normal question to ask. Many people imagine that the universe was an empty space until, somewhere within it, something exploded: the Big Bang.

This suggests that there was an empty universe before the Big Bang. But that’s not the case. Most cosmologists accept that there was nothing before the Big Bang. No universe, no space, no time. They all originated as a result of the Big Bang.

A hot, thick soup

And that formation was happening everywhere. At the time of the Big Bang, the entire universe was a hot, thick soup. It then gradually cooled and thinned out. As a result, we can’t know exactly where the Big Bang occurred.
