Question: Since the Moon is not gone, just broken into pieces, wouldn't this still provide the same mass, and hence the same gravitational attraction? Hard to see how the tidal effect would destroy the Earth without physically removing the Moon's mass. Makes a nice visual, but seems to fall flat on the science.
Question: Maybe this was explained in the film and I missed it, but it has been bugging me for a while. What happened to all the rest of the clones of Jack and Victoria after the Tet was destroyed? Presumably their daily instructions in the form of Sally would cease. Wouldn't they get suspicious? Some reasonable explanation would be nice.
Question: I am curious why there is no lag whatsoever in communications between the Odyssey and Ground Control. We are told that the Tet is initially pretty far out in space, and even fairly close in to Earth there would still be noticeable delays. This instantaneous communication would seem to require some sort of faster-than-light system, which physics says is impossible. So, is there an explanation or is this a mistake? Seems odd to me given the care taken to design the drones and bubble craft.
