Where does the theory of special relativity "predict" that light
cannot be "constant" in a non-inertial frame? Indeed, it is a
postulate of SR that the speed of light *is* constant, the same
constant c, in all inertial frames.

SR doesn't make any predictions about non-inertial frames. On the
other hand, a frame co-rotating with an earth laboratory is nearly
inertial at any one instant in time.

Its a vert close approximation to one .. dummy. The results of MM is
completely compatible with, and supports, SR

Very close has another meaning .. its called fudging it or fiddling
the data. You wouldnt accept an alternative theory if it said its
predictions werent exactly but pretty close to correct would you?

I never said SR didnt predict it to be c in all inertial frames.
I said `non inertial frames`.
And regarding "where" I get this prediction.. Go to neds or wiki
pages with their SR simulations of sagnac. Here they say that
light travels at variable speeds in the rotating source frame.
If you dont believe me LOOK AT their simulations.
Its done with the source rotating in the so called `inertial` frame
(therefore the source is a non inertial rotating frame like MMx)
and the light speed at c in the inertial frame.
If you thought about it you would realise that Ned and wiki
are saying SR predicts that light must travel at variable
speeds in non inertial frames. Its there in their simulations.

Id like to also point out that in fact Ned and wiki are so
ignorant of the facts that even their so called `inertial` lab
frame isnt inertial. Because in fact the lab itself is rotating
around the earths axis. We know this, not least because we
can measure this rotation .

It isnt inertial though . Nearly isnt good enough. Especially when
ring gyros can detect this rotation. If we can detect the rotation
of MMx then its a big enough rotation to mean that the frame isnt
inertial. It would only be inertial if we couldnt detect rotation.
So MMx isnt inertial and it cannot be used as proof of SR. In
fact if SR predicts that light always travels at c in all inertial
frames then MMx conflicts with this prediction. Because if light
were at c in a frame other than the MMx source then a translation
of that light speed to the non inertial rotating MMx frame would mean
that light would have to be travelling at variable speeds in all
directions in the MMx frame, (according to SR)
But this isnt observed in MMx .Its observed to travel at constant
speeds an at c in all directions in the non inertial frame, not
any inertial frame that SR predicts should be the case.
Therefore MMx observations are not consistent with SR predictions.

Physics is a QUANTITATIVE science, and the effects of the rotation of
the earth, its orbital rotation, etc. can all be COMPUTED. When one does
so, one finds the effect is much smaller than the resolution of the
apparatus (reminder: this is the MMX, not a ring gyro).


> Especially when

They are a DIFFERENT physical system, and they react to rotation MUCH
differently.

The MMX interferometer is topologically equivalent to a ring gyro, with
an enclosed area of zero. As the Sagnac effect is proportional to the
enclosed area, the MMX apparatus is not sensitive to rotation.


> So MMx isnt inertial and it cannot be used as proof of SR.

Nobody expects it to be "proof", except people who don't understand what
science actually is. The MMX is inertial enough (see above) to be a
valid test of SR.

Not SIGNIFICANTLY. Physics is a QUANTITATIVE science, and one must
always understand the resolution of the experiment.


You seem to be trying to do physics via sound bites. That is hopeless,
you must STUDY, and use REAL physics books, not youtube. The real ting
is VASTLY more interesting than what the idiots around here try to discuss.
