Question

How can the observable universe be over 90 billion light-years across when the universe is only 14 billion years old?

In: Physics

Answer 1

A light year is a measure of distance, the amount of distance it takes one photon of light to travel in one year. Light travels at 3.00×10 to the 8th m per second. 14 billion years old is a measure of time, not distance.

Edit: Misunderstood the question, sorry
