I'm not going lie I don't know too much about relativity, though I do understand it. I haven't even gone to college yet and from what I've read so far I'm assuming there's much more to know. Anyway, in most of Einsteins thought experiments he speaks about observations in terms of 1 frame of reference. They lead to paradoxes such as time dilation and the increasing/decreasing 'rate' of time. This leads to the conclusion that since each perception is different in its respective frame of reference, all frames of reference are valid. But why is human perception taken into account in the first place? I mean our perception distorts everything. We cant even be sure if everything we are thinking is 100% wrong. Wouldn't it be more accurate to look at events in terms of how the events are happening rather than how the events are happening with respect to something else? What i mean is wouldn't using only one frame of reference be invalid, there by invalidating all frames of reference, and instead using two equal frames of reference simultaneously under similar conditions? This would create a frame of reference that that uses two different FoR's at the same time to cancel out individual perception and prove that is it possible to do something such as (like Einstein said) synchronize all clocks in a town equally. Damn I think I just confused myself stating all that. I should probably read more on relativity. Also sometime I find it hard to put my thoughts into words, its a type of 3 dimensional thinking I believe, or so I was told.
