I’ve seen people explain it before but I have absolutely no idea what they are talking about. An example of what I’m saying would be the movie interstellar or the old planet of the apes movie. It makes absolutely no sense.
In: Physics
Like someone else mentioned already, every object’s speed through space-time = the speed of light (299,792,458 m / s). So, that means:
Speed through space + speed through time = speed of light. Given the speed of which the earth hurtles through space, you and I experience the same speed through time, which we have come to know as the normal passage of time.
Now if you increase the speed at which you travel through space, the speed that you travel through time decreases because the sum of those two still equals the speed of light. In Interstellar, when they visit Miller’s planet, it is so close to Gargantua, that it is moving extremely fast, much faster (relatively) than earth, such that their speed through time is drastically reduced. When they spend what feels like only 3.5 hours to them on that planet, it turns out to be almost 27 years for people on earth. The astronauts bodies only experienced 3.5 hours of time while the people on earth experienced 27 years in the same time frame, meaning the astronauts were moving much slower through time.
