      We can only really talk about the ‘observable’ universe, or the part of the Universe that we can actually observe from the Earth. This is about 93,000,000,000 light years (the distance something going a the speed of light can go in a year) across. That’s about 900,000,000,000,000,000,000,000,000 metres
