Re: Black Hole Evaporation

1. As I understood from the lecture, the whole principle of evaporation is: near an event horizon a particle with a positive energy flees away and it's "negative partner" falls down. Don't they? Quote: : "Falls in: dark energy, Bumped out: "normal" energy". end quote. 2...

Why not quite the contrary?

2. How big is a black hole radius for a proton? quark?
