I was reading some posts on one of my previous threads (great discussion there btw) and I red something that I really didn't understand. So the basic premise was that if we have 2 clocks that undergo acceleration on the same level, to that they are mutually at rest, that they will see their time rates differently. Can somebody explain this? I've always thought that an observer that is accelarating with an object will see the time pass on that object by the same rate as in his own frame. What are the rules here? How will the time flow relative to each other's frame (both frames are mutually at rest and accelerating at the sam rate)?
