Look,
You still don't get it and you are behaving in a manner that is unfitting for a moderator. Let me try to explain one more time (not for your benefit, since you won't admit to error).
In the twins paradox (which was the context of the discussion) , with the help of an accelerometer, the twins can tell the accelerating twin from the inertial one.
Nice try but this was not the context being discussed. Bill and Bob are the twins, one is accelerating away, the other one is not. There is no "gravitational field". If the twins are stationary, then there is no separation and there is no paradox.
I understand that you do not understand, yet you are acting in a manner that is unbecoming for a moderator. Especially since you are wrong. One more thing: don't talk down to me and don't threaten.
