      Space is big. Really big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. 😀

      Given that light (and therefore information) travel at the speed of light, and the age of the universe is 13.7 Billion years, and we cannot see an “edge” to the universe, the universe has a radius of at least 13.7 billion light years – which is 80,000,000,000,000,000,000,000 ( or 80 sextillion) miles.

      So it’s big.

      Unimaginably massive.

      It’s expanding all the time as well, as a continuation of the big bang.

      It’s really, really, really, really, really really, really, really big.

      Have a look at this fantastic link to get an idea of the scale of the universe.
