That is beyond me. But you left out a lot, too.

Of course he left a lot out. He isn't trying to explain the whole theory of

are zillions of simple examples - for example the surface of a sphere is
finite but has no edge.

Still beyond me.

Buy a book. Or google "Moebius strip", "klein bottle", "projective plane"

Two dimensional, three dimentional, one dimentional?/?????

One dimensional.

Lost me back in the beginning.

Yeah, sounds like a fudge. Yeah, I read George Gamow's "1-2-3 infinity"
and he talked about some of this, and, frankly, he did a better job, too.

____________________________________________
Of course he would have done a better job. He was writing for large audience
who were willing to buy his book, not trying to explain some concepts on a
newsgroup for free.

Experimental findings can be misinterpretations and experiment design can
have flaws.

Yes, so? Are you claiming that the thousands of experiments that confirm SR
all have flaws? How do you explain how particle accelerators that are built
using SR work if SR is false?

I am aware of only one "school of thought".

I have heard zero - lets repeat that, zero - alternative theories to SR.
What exist by the crank-case full are theories which claim to be different
to SR, but are in fact mathematically identical in their predictions and so
are the same theory dressed up in different verbiage.

For you to demonstrate a second "school of thought", you have to produce an
alternative theory which has more than one or two nutcases proposing it - a
"school" as it were, and it has to be different to SR in that it makes
testably different predictions, and it has to explain the huge body of
experimental evidence.

This does not exist.

There is no "second school of thought" with respect to the predictions of
Special Relativity, and there is no point on hedging yourself against SR
being wrong.

Cognitive dissonance sets in with the anti-semitic pro-Einstein crowd.
Or Jewish Einstein-deniers.

Did they produce the same mathematical results as SR? Did they propose
testable experiments which would differentiate their theory from SR?

These are the basic tests that you use to see if they really are a different
theory. Did you apply them?

No, this is not two dozen nutcases who belong to some "school of thought".
These are two dozen different theories, with the only thing in common is
they believe they are right and everybody else is wrong.

So yes, there are two dozen nutcases and others (if you say so) published on
Amazon, compared to ummm how many for 9/11 are there?

Well, I am unaware of that happening, but I will take your word for it.

What I can't understand is how this relates to what we are discussing. If
you have a point to make, just say it, and don't resort to some abstrous and
unclear metaphor.
