So unless you were lying, we agree that

And it is because you realized this, that you now are
claiming that an interferometer works in an entirely
different way than physicists think, so there still
will be fringe shifts despite the fact that the ballistic
theory predicts no difference in the light paths.

Indeed it is, Henri.
That was what I told you.
The interference pattern is formed because the path
length difference from a point on the screen to
the two sources is different at different points
on the screen.

But to make that pattern _change_, one or both
of the two path lengths must change.
No angles are changing when the interferometer
is rotated. So when the fringes shift, it must
be because the path length - measured in wavelengths -
of one or both beam changes.

The ballistic theory predicts no changes in the path
lengths, and thus no fringe shifts.

I think you better read my posting again.
Please THINK while doing so this time.

To get an interference pattern with fringes,
the beams must be diverging and overlapping.

Consider this simple figure:

1 2
* * Two correlated (in phase) point sources
emitting monochromatic, coherent light.
(Laser and a beam splitter)



--|--|--|---- screen
A B C

The point B is equidistant to source 1 and 2.
We get a bright fringe through B. The fringe
will be a straight line.
The distance from the point A to point 2 is
half a wavelength longer than the distance
to point 1. We get a dark fringe through A.
This fringe will be a bit curved.
Likewise for point C, a dark fringe.

Note that the reason why there are fringes
at all is that the beams are diverging, so
the distance from the source to the screen
is different on different parts of the screen.

The angle of the beams when they unite
has obviously nothing whatsoever with
the matter to do. The only thing that matters
is the difference in the light path lengths
to the two sources measured in wavelengths.

The only way to make the fringes move,
is to change the distance to one of the sources.
If we move source 1 a bit upwards, the fringes
will move to the left, and vice versa.

So when fringes move, the difference between
the two path lengths measured in wavelengths
changes.

Now let this "interferometer" rotate.
Observed in the interferometer frame,
the light paths will be slightly curved,
so the angle with which the light hits
the screen is slightly altered.
But the fringes will not move, because
the slightly curved light paths from
point 1 to B and point 2 to B will still
be equally long. The angle at which the beams
hit the screen is utterly irrelevant.

And please don't say something like
"the beam will no longer hit point B,
because it is deflected."
That is irrelevant. The beams are diverging
and overlapping, and what happens in point B
depend only on the lengths of the paths of
the light that hit point B, obviously.

The same applies for the four mirror set up.
It is stupid to say something like "the two
contra going beams will no longer combine
at the same point on the mirror."

Some light will always hit at "the midpoint"
of the combining mirror, and what happens in
that point is only determined by the phase
difference of the two light paths that
actually hit that point. If the fringes shifts,
it means that the phase difference changes,
which only can mean that the length difference
of the light paths have changed.

The ballistic theory predicts no length difference
of the light paths (measured in wavelengths)
and thus no fringe shifts when the Sagnac ring rotates.

But the fringes do shift when the Sagnac ring rotates.

Sagnac falsifies the ballistic theory.

No other conclusion is possible.

This whole posting would be funny if it wasn't so pathetic.
You are making it all up just to suit your own theory.

The truth is, the sagnac principle relies on the fact that light has its own
built-in 'gyro' in the form of an 'axis'.
It is not directly related to changes in light speed. Rather, the rotation of
the axes at each reflection gives rise to fringes when the
beams reunite (at different angles).

Was this the best you can do?
Since you cannot refute my arguments,
you flee the discussion.

This is very funny even if it is pathetic, :-)
You are making it all up just to suit your own theory.

So the Sagnac interferometer works in an entirely different
way than other interferometers?
The interference pattern is formed by different laws of nature?
The interference pattern is moving, not because the path length
difference between the two beams is changing, but because
the photons are rotated? :-)

There is no limit to the stupidities you can invent
to explain why the ballistic theory doesn't predict
what it predicts, is it?

> PS: You wont find this in any book.

I wonder why. :-)

Seriously, Henri.
If you really believe your fantasies yourself,
you have a serious sanity problem.

But you do not really believe it, of course.
