SRT: maybe a philosophical thought
===
"If a tree falls in a forest and no one is around to hear it,
does it make a sound?" --
-- is a philosophical thought experiment that raises
questions regarding observation and perception.
Albert Einstein is reported to have asked his fellow physicist
and friend Niels Bohr, one of the founding fathers of quantum
mechanics, whether he realistically believed that
'the moon does not exist if nobody is looking at it.'
To this Bohr replied that however hard he (Einstein) may try,
he would not be able to prove that it does, thus giving the entire
riddle the status of a kind of an infallible conjecture — one that
cannot be either proved or disproved.

In another word: Einstein's SRT proves:
without an observer or a fixed point
we don't know if there is a movement.

I would reply but the post probably disappears when I'm not looking at it. Now if that could be applied to the loco collective . . . .
