I'll bet if you showed this picture to most people and asked them to comment on it, they would refer to the galaxies as “out of focus stars”. Most people don't have any concept of what a galaxy is or its size. Show them a picture of a spiral galaxy and tell them that one of those little pin points of light is like our entire solar system with the sun and its planets and it just blows them away. I still can't wrap my mind around the concept of infinite space. The universe is still expanding...but expanding into what? Aw man...there goes another night of sleep...

The universe is still expanding...but expanding into what?

That area where the Universe does not yet exist. Of course.
