Cosmologists may never calculate the exact size of the Universe. It could be infinite. Alternatively it might have finite volume, but even a finite Universe would have no centre or boundaries and would curve in on itself.

What is certain is that the universe is expanding and has being doing so since it’s origins in the big bang, 13.7 billion years ago. We know this by studying the patterns of radiation left from the big bang, cosmologists can estimate the minimum size of the Universe should it turn out to be finite.

Some parts must be seperated by at least 10 billion light years, as a light year is the distance light travels in a year, (9,340 billion km)

The Universe is magnificently huge.
