If the Milky Way were a CD, then the edge of the *known* universe is 10 miles away, or 134,112 CDs

Imagine that our entire Milky Way galaxy were the size of a CD. On this scale, the nearest spiral galaxy, Andromeda, would be another CD about eight feet away.

 

The furthest galaxies we have ever seen, pictured in the Hubble Deep Field above, would be CDs about nine miles away. The edge of the observable Universe, the furthest we can possibly see, is only another mile beyond that.



How big is our universe?
