Worm Holes Known as a 'bridges' through space and time. Using the theory of general relativity to expand this idea. Worm holes create a shortcut that could reduce travel time and distance. The image above shows the normal route ( curved area of 25ly) and the Alternative Route (worm hole). Interstellar mission is for the astronauts to find a suitable planet for life, using wormholes to decrease the time. In the scene below, they are traveling through the solar system, which would normally take many years, however only takes seconds/minutes in the movie. Overall I would rate this movie s PGP because most of the physics were correct; however I am biased on whether or not wormholes exist and are real.
What is a Twin Paradox? According to Einsteins postulates of special relativity, time dilation occurs if the observer is not in the frame of a moving clock. Or in other words in relation to the movie time runs more slowly on a space craft than it does on earth. In the movie contact Ellie did not remain in the inertial reference frame while Palmer did. The movie in accurately portrays the twin paradox. Ellie feels a force or experiences an acceleration, therefore leaves the inertial reference frame. From Ellies point of view it lasted 18 hours, however to earth-bound Palmer it only lasted about 1 to 2 seconds. What should of happened, was Palmer should of experienced more time passed than Ellie. The interval of time should of been longer for Palmer. In order to fix the scene the recorder should of recorded less time on the ship than on earth, and Palmer and the workers should of passed 18 hours of time and Ellie should have only experienced 2 seconds of time passed.
