Starship Asterisk*

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...

So, they should be some kind of tachyons, right?

1.Why the particle, which falls in to a black hole might have negative (dark) enegry and repulsive gravitational force?
Why not quite the contrary?

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

Can a graviton (which is still not prooved to exist) have a negative mass?
Theoretically, of course.
