IMDB rating: 8.10 Plot: A flying saucer orbits the 1950s Earth. It lands in Washington, DC, on the Mall. The lone occupant steps out and is shot by a jumpy soldier. Gort, a large and very powerful robot appears to save him and is able to melt tanks with the slightest bit of his power. The wounded alien orders Gort to stop his rampage and is taken to a hospital from which he escapes in order to learn more about this planet, even moving in as a boarder with an Earth family. When they begin to suspect him, he reveals himself, along with the news that Gort is a member of a race of super-robot enforcers invented to keep the peace of the galaxy that will destroy the Earth if provoked. |

Question about relativity.?
I’m not a theoretical physicist, I’m a graphic artist who is forced to work in the accounting department of a car dealership.
My mind starts to wander at times and I had this question. And feel free to correct me on my facts, because, as I said… i’m not a doctor of theoretical physics.
Relativity states (in part) that an object’s perception of time is warped by it’s relative speed to another object. i.e. as an object approaches the speed of light (which seems to vary based on the speed of it’s source) time slows down for the observer.
We’ve studied this by sending highly accurate clocks in to space at high speeds and noted their difference upon return.
Now, here is where my question lays. If we pick a currently unknown point as our "center" of the universe; where the Big Bang took place, and from which everything is moving away, that would be our reference point as a non-moving place where time goes at a certain rate. Now, since the earth is moving very quickly away from this point, time would go much slower on earth than it would for you standing at the center of the universe.
So, suppose someone left earth and headed toward me. They would age slower than someone standing on earth to their prospective, but faster than someone standing on earth to my perspective.
Using this theory, wouldn’t that astronaut be aging at an infinate number of rates relative to every perspective in the universe? How is that possible? How could, to the same person, 1 day be 28 hours relative to earth, AND 20 hours relative to earth at the same time just because you have 2 different viewers.
The post made about the twin paradox assumes 2 referrence points… one on earth, and one traveling… my question involves 3 points of referrence… one on earth, one in space, and one truely stationary in the center of the universe. when comparing how one item ages to another, the twin paradox answers my question, but when you have 2 observers, both of them moving at different speeds, the "traveling twin" would age both slower and faster then the twin who stayed on earth depending on if you asked the person on earth, or the person at the center of the universe… or perhaps im missing something…
Or let me phrase it this way:
To the person standing on earth, the spaceship would be the moving the fastest.
To the person standing at the center of the universe, the earth would be moving the fastest.
So, based on those reference points, the person in the space ship would age both faster AND slower than the person on earth.
I think you have formulated the twin paradox. It is explained why on wikipedia in a way better than I can ever explain. I think acceleration plays a key roleand lenght contraction (if you are going near the speed of light, the distance you have to travel appears shorter)

that’s why theory of special relativity says that……time is not constant …….it is also relative..it also changes ….as the observer , velocity etc. changes…………….

, spend sometime with friends. keep busy!, and then you won’t be worrying about it much. Don’t let it bother you either if he’s not spending time with you, most likely he is busy, and if he is, then agree on thursday. but make sure you make him feel special whenever you see him, because that will draw him closer
