Corrected entry: In the beginning, we are shown a sort of picture of the alien ship and all the coral that covers it, that's how they know how old it is, but when we see the ship for real, there's hardly any coral on it. Yes, the coral was supposed to have been blown away, so they can get in and out, but they wouldn't have blown all the other coral away - they could have damaged the ship. And yet, there is the enormous ship, clean of coral.kh1616
Corrected entry: The spaceship was sealed. Since they did not know the pressure of the air within the spacecraft, it can not be assumed it's the same as the ambient pressure, to which they were adjusted. Any change would have effected their bodies. Just as they had to adapt to the base station pressure when they first arrived.
Corrected entry: When hallucinations start; trained scientists not realizing mind affecting circumstances that are OUT of the ordinary, AND suspicious even AFTER seeing clues. Science brains tend to make LOTS of associations and would be detected and at least try to disbelieve any Fantastical experiences.
Corrected entry: When the Navy officer tells Norman to pull the switch that will cover the giant squid with a electrical surge, Beth starts panicking and yells, "You're going to cause a fire." over and over again. After Norman pulls it, a fire starts. This is an obvious manifestation of "the power," but since the only one who would be in the right state of mind for it is Beth, and in that point of the movie she hasn't been inside the sphere yet (only Norman and Harry have, Harry's asleep, and Norman was always the most psychologically stable of the main cast and wouldn't give into panic like that) who caused the fire?
Corrected entry: The crew is being told that, because their bodies are pressurized for the depth, they are able to swim in the water (although it's not recommended because of the temperature of the water). Being at that 1000 feet depth it is impossible to go outside and take a swim (whether you're wearing a diving outfit or not). The pressure is so great that your body would be crushed immediately. If you're 1000 feet deep it means that there's 1000 feet of water pushing on you. Only subs are able to resist such a weight.
Corrected entry: The space ship is lying at the bottom of the ocean, 1000 feet under the water and has a stack of coral growing on it. Coral does not grow at 1000 feet. Coral needs ample oxygen and light to grow. This does not exist at that depth.
