  • And why did generous general Stalin agree to that whole spheres of influence thing in the first place? If he wanted to protect poor Poland from the evil Germanz, surely telling the world about Hitler’s evil plans would have been even better? Or at least warning Poland.

    But hm, strange, nothing of the sort was done. One could get the impression generous general Stalin didn’t care for the plight of the common polish citizen that was just to be unleashed on them.



  • Nearly correct, but it’s not about negative mass, because that doesn’t exist as far as I know. Rather it is about matter and antimatter which have other opposite properties, the mass is the same for both. That’s why it doesn’t matter which particle goes back into the hole, because the creation of the particle pair used up some of the energy (and therefore mass) of the black hole and if both fall back, nothing changes. But if one escapes, a minuscule amount of the mass of the black hole left its event horizon and thereby decreased its mass.
