Vertical Michelson Morley Interferometer Experiment 11 12 2010

Your mirror, as you demonstrated, is a lot less robust compared to Martin Grusenick's so I would expect your fringe patterns to be more extreme if gravity is causing strain. Do you have any explanation of how his equipment could be showing regular fringe movements even during 24hour static tests ( no rotation) in a temperature controlled box?

It is gravity pulling on your splitter as you rotate.

Congratulations, great job. I wanna now what kind of lens are you using? Thank you for the answer.

hi's fringe paterns are horrizontal while going vert .... kool post anyhow !

Congratulations on your experiment. I'd like to point though that the rotation on Martin's experiment was offset and more "planetary", thus creating a bigger circumference (so the rotation axis of the apparatus has to be to exact configuration, maybe even more shifts in fringes can be noticed). Also, using the word "gravitational field" do not explain anything, your just describing something and giving it a name.I tells what it does, but not what it is. A medium is a medium. Hence the Aether.

Great job, Frank. Thanks for taking time to clarify the effect. I wish you the best in future experiments.

Note: In the horizontal rotation, the corner of the granite plate was used to rotate the interferometer, causing a slight fringe shift. This was repeated using the handle and the video was re-edited. This can be found at:

The Grusenick experiment can be found at youtube.com/watch?v=7T0d7o8X2-­E

(When URL pasted, it shows "- - -E". Need to remove all "-" and add a new "-".
