Correcting my lies
In a previous blog post I may have said nothing ever ever ever can leave a black hole. I actually said exactly this, but this guy named Stephen Hawking has been telling me different. Particle production is to blame for this dilemma.
You see quantum physics describes in very fancy terms how particles are created for micro-seconds all over the universe all the time. So say one of these particles and its anti-particle is created just on the event horizon of a black hole and one of the pieces falls into the black hole, well we have a problem now.
Conservation of energy says we must keep everything in balance the taking of one of those particles creates an inbalance in the universe, to account for this the black hole must pop something else out! Usually it is just energy or radiation which gives this phenomena its name, "Hawking Radiation".
This principal idea has been used to explain the destruction of black holes as over time more and more mass is stolen from them until not enough is left and the black hole disappears. The black hole would be vaporized and in theory the black hole would heat up as it expels all this radiation and this is currently what scientists are looking for to prove the idea true. Of course though it can be difficult endeavor to try to find a black hole slightly hotter than other black holes since we have never even seen a black hole before.
So it seems if you did happen to drop your dog into a black hole you may be able to get him back! Just in the form of energy or radiation which sounds better than nothing.
I knew there was a bright side to black holes!
