"Because you make this assertion, you also implicitly assert that you know it to be true, i.e. you can tell [that something isn't moving]." - Oberon
No, by making that assertation, I am pointing out that Reality doesn't care whether we can "tell" or not.
Thus asserting that you've got the goods on "Reality." That's why I referred to praying to you, because if you've really got a lock on Reality, theyn you're God.
Look, I've said some foolish things in the past and later failed to back down from them. In this case, you've done likewise, and no amount of hedging or obfuscatory argument will erase it. I'm going to drop it and go on, because I've got better things to do.
Meanwhile, according to the best theory we have to date:
All motion is relative.
Accept it now; understand it later, if necessary.
