The World of Weird Things blog has a pretty cool look at the part played by big black holes in the origins of the universe:
So this nearly 3,000 kilometer wide brute would be one of the last things to exist in the known universe and in its long life, we should probably expect it to merge with other black holes and gulp down plenty of gas to grow even bigger, maybe even to supermassive proportions, and extending its lifespan to obscenely long stretches of time. Considering that it was far from the only one, one might ask whether we should just look for the center of the universe by the biggest concentration of black holes we can find and finally establish a firm grip on our location in the cosmos. But that’s not how things work.
