I'll try to explain this one more time. Lorentz's theory is SR. LET is
not Lorentz's theory, it is simply a theory that takes a single
assumption of his literally, and then applies it to Galilean
spacetime. The transform for LET is not the lorentz transform. It
falls into the category of transforms that Roberts calls Edwards
frames. It is actually the same as Seto's theory.


Dear RP,

Surely the two of you are discussing what Roberts called "LET". That "LET"
happens to be Lorentz's theory incl. his interpretation, and Lorentz' theory
is indeed SRT (and he also promoted GRT).
In your argumentation of your LET paradox here below, you forgot the most
likely possibility which is that you made a calculation error.
But of course, you obviously did *not* really try to calculate it - for me
this is another "David Seppala". Show your detailed calculation and people
will certainly do an effort to show you where you went wrong.

Good luck!

Here's a simple thought experiment for you. If you claim that
spacetime is Galilean and that the differences in measured speeds are
due to physical changes that clocks and measuring sticks undergo, then
you haven't thought it through. Suppose clock A accellerates away from
Earth to some arbitrarily far point at c, where it again comes to rest
wrt Earth's frame. It will not have ticked at all during the trip. Now
another clock (B) is sent to the same point at the same speed wrt
Earth, and it leaves exactly one second (Earth time) after clock A
comes to rest. We'll assume constant velocity (c) during the entire
trip and instantaneous accelleration, in order to simplify the thought
experiment. When B comes to rest next to A, then clock B will lead
clock A by one second. This is all assuming that Earth is at rest wrt
the Galilean aether.

But suppose that the moving frame of the clocks is actually the rest
frame and that Earth is moving at c wrt the aether. Now when clock A
leaves Earth its ticking rate increases instead of decreases, since it
has slowed to a stop, i.e. decelerated. Now it advances concurrently
to aether frame time during the entire trip. The one second delay in
launch times has now become infinite time because the entire Earth and
all of its clocks aren't ticking at all wrt our new aether frame. When
clock B arrives it will lag clock A by all of eternity.

If you want to do some actual math, then let the relative speed be
less than c. You will not get consistent results, but you will at
least get the clocks to leave Earth. For this reason LET does predict
that the aether frame can be detected, whereas use of the lorentz
transform does not allow this. If the acronym "LET" is to represent
the above theory, then LET isn't equivalent to SR, and nor can it be
lorentzs theory, even though the above might have been his initial
premise. Lorentz theory is equivalent to SR, and thus can't be the
above theory. I can only assume that his initial premise was buried
by the math that he finally developed, a fact that he failed to
notice. And this is essentially what Einstein concluded, i.e. that the
lorentz transform does not admit to an aether, Lorentz's verbal
arguments weren't logically sound, nor consistent with the math.
