The Black Hole Bomb and Black Hole Civilizations

Black holes are pretty cool to study, not cool to get close to, but did you know that black holes spin? You never thought about it before, but since everything else in space spins, it makes sense. What's really cool is that we could theoretically harness this energy. In reality, we are nowhere near having the capability of approaching a black hole, much less surviving such an adventure. From that point, this video from Kurzgesagt takes the theoretical possibilities to the next level by explaining how to make the biggest bomb in the universe. We know the science, but we are far from being able to do it ...at the present time. (via reddit)
