: I think we have reached a miscommunication between our answers and responses.

: I completely understand special relativity, I know that the rate at which time elapses for an object is dependent on its relative velocity.

: When I asked the question "Do two objects, between which is a given distance, exist in the same moment of time." I did not mean "Do two objects, between which is a given distance, experience the elapsation of time at the same rate."

ZC: I am not talking about time dilation at all. I'm referring to relativity of simulteneity.

: If you would like another stab at answering what I'm trying to express, I'll try to rephrase it one more time.

: "Do two objects, separated by a distance, "ever" exist simultaneously?"

: If you can, please provide proof in your answer.

ZC: I am saying if two objects exist at the same time according to one observers coordinate frame, they don't necessarily exist at the same time according to every other observer's coordinate frame. I've been trying to say that there is some truth to your point. There is no absolute simultaneity.
