>>50896358To continue from this, because I forgot about it yesterday, the real fun stuff starts when you apply time to this model.
Basically, light always takes the shortest path possible from A to B.
And light also always travels at a constant speed, 299 792 458m/s, no matter what.
So how would this then work if one light particle travels on straight spacetime and one goes through one of these bends, both traveling from the same point A and arriving to the same point B?
Well, since both particles are traveling at the same speed, but the one going through a bend is seemingly taking a longer route, you would think it would arrive to point B slower than the other particle, right? Wrong!
See, they are both taking the shortest path possible through space, ignoring whether that space is bent or not due to the mass of a nearby object, and their speeds are the same, they will always arrive to point B at the same time. But how?
Time.
Basically, because their speed is constant and they are going along the same, shortest path, the passage of time for the one going through the bend in spacetime will slow down to where the particle will always be on the exactly same point in the route as the other one.
And this is observable in nature in fact, the clocks on ISS(international space station) are slightly faster than those on earth, and the clocks in all GPS satellites also accommodate that slight shift in time. And theoretically, if you were to fall into a black hole, from an outside perspective, you would seem to slow down drastically, before of course, blinking out of existence as you pass the event horizon.
