Re: Anyone here know about physics? III
Well black holes are basically the be all and end all of gravity wells. Once something reaches a certain mass, it's gravity starts compressing it into an infinitely small space (take a moment to consider the word "infinite". This is crazy **** we're talking about). There is basically a zone around that area (particle? point? I dont know what to call it. But it's small as ****) where nothing can get out. The edge of this zone, where it meets normal space, is called an event horizon. Once something passes it, that something would require infinite acceleration to escape (again, consider the word "infinite").
Quantum physics stipulates (apparantly. This **** is really confusing) that all over the universe, pairs of particles (positive mass. Not charge) and antiparticles (negative mass) are spontaneously appearing, and subsequently annhialating themselves on each other (+1 + -1 = 0).
We always thought that black holes suck everything in, and don't let anything out. We were technically right, but also wrong at the same time. Just outside the event horizon of the black hole, the gravity is so strong that the particle pairs I mentioned earlier don't have time to annhialate themselves on each other. For some reason, the particle with negative mass get's sucked into the black hole (which reduces the mass of the black hole, no?), and the positive particle escapes. This makes it appear as though the black hole is emitting radiation (though this isn't quite correct. It is merely attracting particles with negative mass). Nevertheless, the effect is the same. The black hole evaporates over time (at an accelerating rate), and once a critical mass is reached, the black hole explodes with a bunch of random energy (random in the type, not the amount).
