in the movie “Interstellar” time goes by much faster for the main character on the ship than it does for the people back on Earth. How does this happen?
In: Physics
Wormholes are basically what happens when you fold a piece of paper and pierce it with a pencil. No one really knows what happens inside a wormhole, but you can imagine that to move between two very distant points in a very short time you need to go very very fast. Einstein’s relativity describes what happens to things that move to a velocity close to the highest possible one (light speed). To understand it, you need to understand what relativity means: imagine three people, one on the platform of a train station, one on a train going in one direction, and one on a train going in the opposite direction: the guy on the second train will move much more faster relative to the guy on the first train than relative to the one on the platform. This happens with time too: the daughter on earth is moving very very slow relative to the speed of light, so time will flow much slower than for the guy who’s moving at near light speed.
