Ask Ethan: Where did the Big Bang happen?
Ethan Siegel

A 12-year old girl asked this question in the UK but, unfortunately, she called it the centre of the universe and Prof. Brian Cox explained that everywhere in the universe is the centre of the universe and didn't answer the question posed by this article nor the girl’s question.

This has profound implications for the age of the universe which is given as 13.8 billion years because the light from the most distant galaxy took 13.8 billion years to reach earth. But how far is earth away from the location of the Big Bang? Surely, it’s further away making the universe much older.

The sun is around 9 billion years old. Shouldn't we at least add that to the 13.8 billion?
