Einstein defined truly or absolutely synchronous clocks as follows:(adsbygoogle = window.adsbygoogle || []).push({});

"The simultaneity of two definite events with reference to one inertial system involves

the simultaneity of these events in reference to all inertial systems. This is what is meant

when we say that the time of classical mechanics is absolute. According to the special

theory of relativity it is otherwise."

Suppose we have a double-armed baseball tossing machine that can toss two baseballs

equally forcefully in opposite directions. If this machine is placed midway between two

unstarted-but-set-to-start-on-zero clocks, it seems to me that a couple of machine-tossed

baseballs would start the clocks at absolutely the same time, thereby absolutely synching them.

Is there any physical reason why this won't happen? Just wonderingâ€¦.
