After Earth

Question: The alien predators are blind and hunt by pheromones. Why don't humans just wear hermetically sealed suits to block the pheromones, or use false pheromones as decoys?

Answer: Probably because it wouldn't work. On "Mythbusters," Adam and Jamie tested whether a tracking dog could still trace a human clad in a hermetically-sealed suit to contain the scent. The dog easily tracked Jamie.

Other mistake: When the ship begins to crash, Cypher Raige tries to calm Kitai down and is violently pushed to the far left by the force of the ship accelerating. However, less than a few seconds later, the camera shows that to Kitai's right, the force is now tearing the back end of the ship apart and sucking people outside. This is contradictory because the massive air current resulting from the ship's acceleration would have either sucked everyone, including Cypher Raige, outside, or it would have pushed them inward, which we see with Cypher Raige. There is no way for the force to suddenly change directions within the same area of the ship.
