Tragedy: Russia’s orbiting zero-g sex geckos have all died

These aren't our illustrious orbiting sex geckos, but they are the experiment's ground-based control sex geckos, and that's almost as good! — These aren’t our illustrious orbiting sex geckos, but they are the experiment’s ground-based control sex geckos. (credit: imbp.ru)

Geometric meaning of the black hole horizon (PDF)

The event horizon is the boundary between a black hole and the rest of the universe. Any matter that spirals in toward the black hole and crosses the event horizon disappears. Ann Feild, Space Telescope Science Institute — Recent proposals postulate the existence of a “firewall” at the event horizon that may incinerate an infalling observer. These proposals face an apparent paradox if a freely falling observer detects nothing special in the vicinity of the horizon. (Credit: Moffat, Toth, Feild)
