I do get irritated by your ill-mannered, mid-conversation exits, Roberts,

This is not "ill-mannered" on the scale of this newsgroup. I am merely following
Tom Lehrer's dictum: "People who have nothing to say should at least SHUT UP."

Gee! Tom, so you do take your time to respond to posts that address
your professional integrity. You just choose to respond to the ones
you know that you can manage. The ones not manageable by you are
conveniently kept silent as per Tom Lehrer. shrug

I abandon a thread when I have already said everything I have to say.

Or when it is Koobee Wublee which you know you will be checkmated.

This is
the only sensible response to fools and idiots who repeat, and repeat, and
repeat the same words and mistakes.

Ahahaha... In case if Tom has not realized, the self-styled
physicists have repeated the same pieces of bull**** for over 100
years. shrug

There is a long list of participants around
here who ALWAYS get the last word,

Yes, Andro the psycho, PD the imposter, Eric Gisse the college
dropout, Paul Andersen the very small professor, etc. shrug

because they are persistent and apparently
have nothing better to do;

Paul Andersen likes to chase after chickens close to the Arctic
Circle. Does that mean anything to you? shrug Oh, the late
Bielowski liked to swim and bragged about swimming naked in public
lakes. shrug

I merely give them that boon as soon as it is obvious.

Or burying your head into the ground like an ostrich. shrug

modeled).

Right, so Tom and self-styled physicists have claimed the existence of
this mythic proper time. The Lorentz transform only indicates what
the observer’s time flow and what the remote local time flow of the
observed are. As you know very well, the Lorentz transform works as
it is without the introduction of this mythic proper time. So, where
is the rational basis of predicting the existence of this proper time
thing? And how do you suppose to measure the proper time as an
experimental physicist? These are very fair questions. Why are you
always avoiding answering them? shrug

Recall the Beach Boy song?

“She had the fun, fun, fun, until daddy takes the T-bird away.”

Koobee Wublee’s version:

“Tom has had the myth, myth, myth, until Koobee Wublee takes the
proper time away.”
