Alien (franchise) "everything wrong" with his script. On its way back to Earth, the U.S. commercial spaceship "Nostromo" is diverted to a desolate planetoid by a cryptic signal from a derelict alien spacecraft. While exploring the alien ship, one of the "Nostromo"s crewmen discovers the remains of the ship's pilot and also a large chamber that contains thousands of egg-like objects. One of the eggs releases a creature that attaches itself to his face and renders him unconscious. The others break quarantine to bring him back aboard the ship. The parasite dies and the crewman wakes up, seemingly fine. Soon afterwards, an
Bell's spaceship paradox proper time in the momentary frame, and the momentary velocity is given by The mathematical treatment of this paradox is similar to the treatment of Born rigid motion. However, rather than ask about the separation of spaceships with the same acceleration in an inertial frame, the problem of Born rigid motion asks, "What acceleration profile is required by the second spaceship so that the distance between the spaceships remains constant in their proper frame?" In order for the two spaceships, initially at rest in an inertial frame, to maintain a constant proper distance, the lead spaceship must have a lower
