Water Planet- How'd they know that the sea was shallow enough to land in? The ship's engines apparently can't run if wet. So landing here was pretty risky. Would you land a plane in a foot of water not knowing if it was 1000' of water? You can't take off if the engines are wet!
When a big wave hits, (on earth) one of the signs is that the water in a bay will recede. Why didnt this happen when the big waves hit in the film?
Ice Planet- 80% of earth's gravity (IIRC) Yet a "frozen cloud" can hold up it's own weight. Fun world, very sculptural. Is there any way these shapes can hold themselves up? Might be more believable if planet had 10% of earth gravity. Those jump jets also more plausible in low G.

Appearance- At first, this seemed pretty artsy- bizzare. But i'd read that lots of research + computer modelling went into it. So here's my assumtion explaining the visual: The black hole has a simple ring of hot debris orbiting it like the rings of saturn. This stuff isn't close enough to have it's light sucked in. Looking above, or below the "hole", Light from the backside of the ring is bent around to our "eyes" by gravity. This causes the illusion of a second ring perpendicular to the first one. If we coud "look" with some means unaffected by gravity, we would "see" a single ring.

IIRC, the crop blight is "using up" the N2 in the atmosphere?? um...
Overall, a really good flick, addressing big human questions. Of course the human story is the most important, tough decisions face these characters.... but chat on sci should be fun, too.
