Here's the only way to destroy a black hole

I've suggested a bunch of crazy ideas, like blasting it with rockets, shooting lasers at it, smashing planets into it. Nothing would work, everything would just make it bigger and angrier.<p>Turns out the only way to defeat a black hole is to sit on your hands and wait for it to evaporate. That's not …

Physicists 'Squeeze' the Uncertainty Out of the Uncertainty Principle

Thank absolute zero temperatures and something called 'quantum squirting.'<p>Life in the quantum realm means never sitting still. A photon doesn't rest (or "stop") because it turns out that achieving zero energy and, thus, complete predictability requires a bit more effort than it does to just buzz …
