1) If you could hover over a black hole's event horizon (let's say it was a BIG hole with lower tidal forces and you could hover 1 mile out), and stuck a 1mi long pole over the event horizon such that 1mm of the tip of the 1mi pole were over the horizon, would the entire pole be ripped out of your hands? Could you pull the 1mm tip back out? I assume you couldn't.
2) I'm still slightly confused by Hawking Radiation. Almost all examples I've read give an example of two virtual particles developing OUTSIDE of the event horizon, and one particle being pulled into the event horizon while the other is escaping. I'm unclear as to how the black hole loses mass when it is adding particles from outside. One example I read said that the particle that gets pulled into the horizon gains gravitational energy from the black hole and turns into a real particle, hence the hole loses mass. However, even if the black hole lost gravitational energy to the particle that got sucked in, isn't the energy sucked back into the black hole? How is energy lost. I'm hoping one of you can give a hobbyist physics enthusiast a non-mathematical explanation of the whole phenomena.
