Mandy correctly points out that traveling faster than the speed of light is impossible per Einstein physics, when mocking Wendy and Hodges' love of the show. But Star Trek - Galaxy Quest's "real life" inspiration, generally follows the same laws of physics.
Ships in Star Trek do not, in fact, go faster than the speed of light - their "warp engines" effectively warp space, effectively shortening the distance the ship has to travel, at sub-light speeds. Not only does it fit within said laws of physics, it's one of the main scientific theories as to a method of humans eventually achieving interstellar travel.
