Carl, the MMX did not prove that there is no ether. The MMX was fatally flawed, in that it was done in our atmosphere, where the speed of light is c/n = 299,709,438 m/s. That speed is relative to the atmosphere, so a null result should have been expected. This simple statement is perhaps made with the benefit of hindsight, but surely any physicist worth his salt would have known that fact even then. As far as I am aware, the MMX has never been repeated in a vacuum, but would, in my opinion, give the same null result.<div><br></div><div>Tom Hollings<br>

<div><span style="font-family: Arial; font-size: 10pt;">I suppose that I am the only Theoretical Physicist
available to respond. No. Your idea is intriguing, but not
valid. Yes, if there were aether in space, different considerations might
apply, but unless you can do Tensor Calculus in Riemannian Geometry, you would
not be able to try to quantify such an effect.</span></div>

<div><span style="font-family: Arial; font-size: 10pt;">You are basically trying to do what Michelson and
Morley did, for about ten years of math, regarding their experiment. They
also had to use that same exotic math to do the required calculations. And
even though their MM experiment was INTENDED to CONFIRM that the aether existed,
their years of math and multiple failed experiments SURPRISED them
(especially Michelson) to eventually concede that they had (unintentionally)
proved that the aether did not exist. The geometry regarding a Double Slit
is a lot more complicated than their MM experiment, mostly because the space
angles involved for every path in the Double Slit involves different angles in
space (where MM was a far simpler apparatus, where space angles were
consistent). If you have ever done any Double Slit experiments, you know
that there are a LOT of stripes involved. I still remember the FIRST
time I was required to do a Double Slit (50 years ago), I had to find really
precise Trig tables for the required accuracy of the different path lengths from
each slit to a black line (computers and their precise Trig did not then yet
exist). </span></div>
<div><span style="font-family: Arial; font-size: 10pt;"></span> </div>
<div><span style="font-family: Arial; font-size: 10pt;">I credit you with the IDEA of wanting to use
the geometry and trigonometry of a Double Slit for your intention, but if you
actually ever try it, you will see that you will NOT be able to measure
all the dimensions accurately enough (likely by a factor of a thousand to
one). It is a popular experiment in conversation, but a nightmare in
actually trying to measure everything well enough in actual
experiments.</span></div>
