This is a computer image with the black holes that riddle the universe highlighted.

At the center of most galaxies lie black holes. While the universe is expanding and forming new things, the black hole is compressing and making things one again, as they were at the Big Bang. 

Black holes are like little round rear view mirrors, so while we’re flying down the highway to nowhere, we can see where we’ve come from, oblivion, and whether it’s catching up to us.
