The Limits of Our Knowledge in General Relativity and Quantum Theory

When you fall inside the event horizon of a black hole, there's no escaping, no matter what you do or how you accelerate. Even if you travel at the Universe's speed limit, the speed of light, there's simply no way to get any closer to the exit. Instead, scientists say, you have no choice but to fall inevitably towards the singularity at the center. But why must you arrive at a singularity? Couldn't you wind up at some degenerate object instead? We don't think so, and here's the science behind why. Find out what's at the center of a black hole today!
