When Cooper crosses Gargantua's event horizon (after detaching from Endurance), everything goes pitch black. But why? Cooper should still have been able to see the portion of light from the accretion disk that also crosses the event horizon. Crossing the event horizon simply means that light can't ever get back out, not that it disappears straight away. This is the same reasoning that says that a meteorite that crosses the Earth's event horizon (i.e., the point where the escape velocity of the Earth's gravity well exceeds the velocity of the meteorite) can't get out to space again, but it doesn't disappear or immediately plonk straight down to the ground.

    This question should be here: Space Exploration Exchange. – Daft Feb 16 '15 at 13:05

    @Daft If this gets migrated, I think Physics is a better home than Space Exploration. – alexwlchan Feb 16 '15 at 13:23
  • @alexwlchan ah I knew there was a more suitable one than space exploration!! Cheers – Daft Feb 16 '15 at 13:25

    @phantom42 Tha clause "unless they relate directly to a cited work of fiction" seems kind of silly. I guess science questions are off topic regardless of whether they pertain to a cited work? – user14111 Feb 16 '15 at 15:13
