A comment about time|
Google "Dark Flow" sometime.
Basically, some distant galaxies are screaming off in a direction different than all the other galaxies we see. They are close to the edge of the known universe, and that is making scientists wonder if there is some incredible mass just outside of it, pulling the most distant reaches of the universe towards the edge of the universe.
What happens when something reaches the edge? What could possibly be outside the universe but still able to affect it via gravity? Good questions all.
