List of common misconceptions about relativity?

[zonde]

For a myth, how about "SR has proven the aether does not exist." I'm not advocating for aether, but there's a big difference between proving that something cannot exist in a theory versus merely acknowledging that it isn't necessary in that theory.

As I see this is rather complicated question. Obviously it's a myth. But at the time people where probably hung on the idea of finding preferred frame. So such a myth would ban useless discussions.
But nowadays I would say that such a myth promotes kind of magical thinking. That's because dimensional modelling is very powerful tool for consistency checking but that myth kind of prevents using it. But that's my viewpoint.

And another thing that I considered quite interesting (somewhat related to relativistic interpretation of aberration). This is actually a paradox kind of thing but it of course is related to some misconception (if you have it).

Let's say we have situation like this:

Observers "1" and "2" are observing box with an "A" printed on it's side. We view this situation in rest frame of the box and first observer. Second observer is in motion in that frame. Neither observer can see the "A" on the side of the box when both observers are side by side.

Now let's change to rest frame of second observer:

The box and first observer is in motion in that frame. Because the box is in motion and light doesn't get to observer instantly second observer see the box in it's past position. So should the "A" be visible for him?
