Plot hole: In the scene where the crew's vessel gets stuck in the giant geode and the crystal jams the 'impeller', the magma begins to fill the chamber. They see it melting the crystals, yet they frantically continue working to free the crystal from the impeller and lose a crewman...and yet when they get back in the vessel, the magma indeed melts out the crystal that jammed the impeller. With 2 geologists onboard you would think they'd know that.

Other: In the melting bridge scene, the space microwave was powerful enough to melt the bridge's thick metal but how come it could not melt the roof of the cars on the bridge?

Factual error: In the scene where they realize they need to make the last nuclear explosion 30% bigger, they simply pull the fuel rods from the reactor and set them next to the bomb. This is ludicrous, a nuclear bomb is a carefully engineered piece of equipment, with carefully shaped charges imploding the radioactive material. Setting some fuel rods next to the bomb will accomplish nothing.

Factual error: In the scene where 'Rat' is trying to hack into Project Destiny control, he gets several '404' errors, but '404' is page missing, not access denied. It should say '401- Access Denied'.

Continuity: At the end of the movie when they are looking for the survivors they have no signals and decide to give up. Rat is upset, we see a close up of him and his hair is long in the back. The next scene he is walking on the deck of the ship, he figures out the signal and calls to the general waving his arms and screaming. We see him in close up again and his hair is very short in back. Did he get a haircut on the way to the deck?

Continuity: In the scene near the end where they are shooting across the F-115 carrier, you can clearly see about 15 to 20 jets parked on the carrier, the camera goes in the carrier for 50 seconds to a minute, then the camera shoots outside of the carrier and you can see that there are only 5 to 7 jets parked.

Continuity: In the scene where Beck is in the command section of the ship with Zimsky and the rest of them in the weapons center, we can see that the screen she is looking at shows a shot of the black stuff coming towards them. The shot changes but then when it comes back to the screen, you can see the exact same footage used a moment ago.
