The Michealson-Morley Experiment
« on: October 11, 2008, 04:32:38 AM »
Hey guys,
I was wondering if anyone has performed a recent attempt at the suposed 'null' resulted experiment of Michealson and Morley and if so would I be able to look at the results? I would love to try it but I don't have the correct tools to set the experiment up.

Why? Are you not believe in the experiment?

What did they assume in the first place?
That the earth is dragged through an aether, so the light should bend, lag, whatever, which it didn't, so no aether.
But the nay-sayes tell that the aether is dragged along with the earth, so you get the results M&M got.

It is much more complicated than that. Faraday and Tesla both imply an aether exists, because of the paradox and longitudinal waves, so we could figure it out by investigating those.

Actually, the Michaelson-Morley experiment was *NOT* a failure-- it only failed to produce the results anticipated by the experimenters.  The results were actually slightly positive-- (if it were just "noise" you would expect a Gaussian distribution of positive and negative numbers that averaged to zero).  This caused many scientists to speculate that the Aether was being "dragged around" by the Earth.

Later on, Dayton Miller performed the same experiment with a much more sensitive instrument.  Instead of deep underground in a basement, he was on top of a mountain, inside of a tent.  (This was a test of the "dragged Aether" theory).  This experiment produced positive results, but by that time no one wanted to hear about it (as Einstein's relativity theories had become all the rage in scientific circles, and any data that refuted Einstein's theories was not welcome).  After Dayton Miller died, another professor did his very best to destroy all of the experimental data, discredit Mr. Miller's work, and to bury the results.  Enough data survived though that we now know what professor Miller did, and that he was was successful.

Later on, another scientist found that the speed of light is not constant.  (Sorry I can't remember the name of the scientist, but you can Google it).  What he did was shine laser beams through moving water.  In the experiment, the speed of light was increased or decreased by the velocity of the moving water (depending on if the light was traveling upstream or downstream).  This is in direct conflict with relativity theory-- which relies on the postulate that the speed of light is constant (no matter the velocity of the source or the medium that the light is traveling in).  This scientist's paper passed muster in peer-review, and his results were repeated by others.  The ring-laser gyro (used in classified inertial navigation systems by our military) works on this principal.

So, it would appear that the Earth does indeed "drag the aether around" with it as it spins and revolves.  (So does a spinning magnet-- Google the "Aspden Effect" for an explanation).  This would also create a local "spin field" close to the Earth-- so other bodies getting close to the Earth would exhibit a slight tendency to start spinning in the same direction as the Earth.

I would add a different effect called "Sagnac" which shows that all
these experiments are reinterpreted right now after a century  ;D
