Eli5: How is the size of the universe 95 billion lightyears if it’s only 13.7 billion years old?

552 views

My partner asked me this but I’m hardly smart enough to understand the question. If the Big Bang was ~13.7 billion years ago and nothing can be faster than the speed of light then how is the size of the universe 95 billion light years across?

Please explain this to my like I’m 5. Thank you!

I’m going for even simpler…

Imagine you live in London and a friend sends you a postcard from Paris telling you he is just getting on the train to Istanbul … when you receive the postcard how far away is he?

Does that work , or over simplify … I’m not sure.
