The very word 'relativity' requires mutually symmetric perspectives.

This goes like this:

you stand there, I stand here and I see you.

Now the opposite should also be possible, but from your perspective.

This means: you see me, while you would call yourself 'I', your own 
location 'here' and mine 'there'.

This would give:

you stand there, I stand here and I see you (but said by you and from 
your point of view).


Since both perspectives are of equal rights, we need to accept both 
views as valid, hence need mutually symmetric perspectives.

Negative statements are difficult to prove.

But I can ask you, to prove the opposite and prove, that you failed.

So: where exactly did Einstein take delay into consideration in his 1905 
paper??
