The connecting tube between the two rotating sections of Pangea is unaffected by the rotational effects built to generate centrifugal force simulating gravity. The occupants should be floating freely through these areas.

Based on NASA findings in a late 1960s toroidal space colony concept, the rotational speed of Pangea's rings is much too high, essentially a third faster than it should be. The coriolis effect would make living inside a nightmare of fighting off constant motion sickness.

The plot hole in this film is so massive it prevents any entertainment from escaping. The expository premise is that in the late 22nd Century, there is only one space colony in the entire solar system, and it's on the Jovian moon of Europa. Predicting the future is tricky, but if you're going to cancel the likelihood that humans will live in colonies on the Moon, Mars and maybe in Venusian orbit by then, you need to justify it. Just making up a severely limited expansion into space so that you can tell a simpler story is lazy writing. Even worse, there's absolutely NO NEED for a refueling station between Earth and Jupiter. It would take about the same amount of fuel to stop midway as it would to just keep coasting and stop at Jupiter. If you stopped anywhere, you'd have to use fuel to accelerate back to trans-orbital speed. Totally stupid. In fact, it would most likely take LESS fuel to stop at Jupiter because there are multiple moons and a large planet available for gravity braking. Finally, the logistics of keeping a refueling station in an optimal flight path between Earth and Jupiter (which orbit at very different rates) is mindlessly ridiculous.

The correct term for a lack of proper nutrition is "malnutrition," not "malnourishment." Also, the doctor meant "manifesting" when he said "manifestating."
