A researcher has re-done the Michelson Morley experiment. In the plane of the Earth he got the same null result. However his apparatus was able to rotate not just in the Earth plane, but orthogonal to it.

Here is the experiment

As far as I can tell he has worked out a method of observing, and also quantifying, the effect of Earth gravity on light.

I would be interested in your comments

How about this then?.
I say there is an aether.Its nature is that it is frictionless (does not resist movement) but does resist CHANGE in movement.A sort of all pervading differential fluid.

The Michelson Morley experiment was doomed to find nothing from the start.
The apparatus detects only acceleration not velocity.

Mean anything to you?.

One hour later.I think I am mixed up about who said what but this post stands as is.

GR says (correctly) that gravity is equivalent to acceleration.
No wonder the interference pattern changes with one light path vertical.

In Earth gravity light falls at the same rate ,accelerates downwards,as everything else whatever the mass or lack of mass.
Over a distance of 300 meters light falls (is deflected if you prefer) down by the same amount (distance ) as any mass does in 1 millionth of a second.
(Speed of light 300,000,000 meters per second.)
Mass has no effect on acceleration in a gravitational field.
Field?.
What am I saying?.
Gravity is not a force.
It is the equivalent of the upward acceleration of the Earth surface.
I am not saying the surface IS accelerating upwards just the the effect
is equivalent.
That is GR.

And this is news, why? The Pound-Rebka (http://en.wikipedia.org/wiki/Pound-Rebka_experiment) in 1959 measured the same thing fifty years ago.

Here is another similar experiment to your link

http://blog.hasslberger.com/2009/09/extended_michelsonmorley_inter.html

My own design of this experiment can be seen here (http://www.bautforum.com/against-mainstream/83686-forrest-nobles-pushing-gravity.html), first posting third paragraph.

For these experiments to provide the evidence for the existence of the aether they have to do more than show the gravity causes a redshift and fringe interference between separated beams. Such experiments must have unquestionable methods, design, and have verifiable results which cannot be interpreted in a different way, as indicated by Tensor's link.

http://en.wikipedia.org/wiki/Pound-Rebka_experiment

For such an experiment to work it seemingly would have to show that the speed of light varies up vs. down in a gravitational field or some other direction/ scenario, be source additive, or in some way differ from the predictions of SR or GR. As you suggest, unambiguous, quantifiable, verifiable differences in the speed of light or effect(s) of some kind, will be the key for such experiments to be considered by mainstream physicists.

Undidly This looks like an ATM claim.
Please keep it out of the Q&A Forum

Good morning from the shire

The person who produced the video of his demonstration in the OP made no claims for the effect. It seems to me that what he is observing is gravitational redshift. I was wondering if the effect measured this way validates General Relativity? Seems to me such a device could produce a very precise measurement of the effect of gravity on light. Also a similar experiment could be conducted in a geosynchronous orbit to measure the rate at which Gravitational Redshift falls off with distance (currently thought to be inverse square I believe).

Lastly it would be interesting to measure this effect at the Earth poles and equator

Thanks

Thank you for bringing this article to my attention.

Interesting thread.
