SR fundamental contradiction
------------------------------------------

Luttgens:

Let x = ct.
Then x' = g(x - vt), where gamma = 1/sqrt(1-v^2/c^2), becomes
x' = g(c-v)t
What represents the length (c-v)t?
Is that length "dilated" by g?
SNIP

Luttgens:

Any object (stick) measures shorter in terms of a frame relative to
which it is moving with velocity v that it does as measured in a frame
relative to which it is at rest, the ratio of shortening being
sqrt(1-v^2/c^2).
This is a relation between measurements referred to different frames.

If a stick of length x' = g(c-v)t is at rest in the S' frame,

Aargh!

Usually sticks are supposed to have a constant length.

Doesn't matter.
Pick some fixed t, say 0.0001 and work from there.
My words were:
"Consider the event E on the light signal with x = c t for some
chosen value of t."
