I *don't* claim to disagree with mainstream physics, and btw my
gender is male. Furthermore (in case by "she" you mean this
hypothetical Aunt Sally) I believe I have not mischaracterized Sue's
position on this matter. She is free to correct me if she wishes;
and even *you* are welcome to present evidence that I have done
her any injustice.

Einstein correctly predicts what is measured by the observers'
local clocks, and you are correct in saying that these measurements
differ. There is nothing obvious about any of this -- you have to *do*
the measurements. Of course you can argue over whether such
measurements are really "time" but the measurements themselves
are not in question (certain crackpots excepted).

FWIW, I don't claim to be one.

However, if we are to believe what Sue is saying about the twin
paradox, 100% of mainstream physicists since, oh, approximately
1905, have been idiots. You have to be an idiot to claim that the
moons of Jupiter orbit a different number of times for one twin than
for the other twin. That's what Sue is telling us that physicists are
claiming. (Which in fact they do not.) IOW, Sue is saying that
physicists are idiots.

This makes it a little hard to see why she is recommending that
we read websites put up by *physicists* at MIT and UT, but I'm
willing to accept that there are aspects of Sue's use of logic that
will remain forever beyond my grasp.
