Discussion Overview

The discussion revolves around the feasibility and implications of conducting vertical interferometer experiments, particularly in the context of historical experiments like Michelson-Morley and Miller. Participants explore the challenges of constructing such experiments and the relevance of gravitational influences on light speed measurements.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that original interferometer experiments were conducted parallel to the Earth's surface and question whether vertical experiments have been performed.
  • It is mentioned that constructing a vertical interferometer poses significant challenges due to structural distortions under its own weight.
  • Participants discuss alternative methods to investigate the constancy of light speed in relation to gravitational fields, including the changing orientation of horizontal devices relative to the sun and moon's gravitational influence.
  • One participant expresses interest in the concept of gravity as an aether inflow and seeks evidence to support or refute this idea.
  • A reference is provided to a paper discussing the aether inflow concept, but another participant dismisses it as coming from a non-credible source.

Areas of Agreement / Disagreement

There is no consensus on the validity of the aether inflow concept, and the discussion reflects differing views on the credibility of sources and the feasibility of vertical interferometer experiments.

Contextual Notes

Participants express uncertainty regarding the construction challenges of vertical interferometers and the implications of gravitational fields on light speed measurements. The discussion also touches on the credibility of certain references and ideas presented.

The original interferometer experiments -- Michelson-Morley, Miller, etc. -- were all done parallel to the Earth's surface. Have any been done vertically?

Yes, although some of these experiments have found only that it is difficult to build a structure that can be rotated from vertical to horizontal and back again without it distorting by even a few nanometers under its own weight.

If you're looking for evidence that the speed of light doesn't change when moving parallel to or perpendicular to the local gravitational field there are other ways of doing that. Consider that a M-M device that is horizontal on the surface of the Earth is still changing its orientation relative to the gravitational fields of the sun and moon; although small these fields are detectable. And of course these days every GPS receiver on the surface of the Earth is validating the light-speed assumption vertically as well as horizontally every moment it's operating.

Thanks. I appreciate the problem. The original interferometers were floated in tanks of mercury, which can hardly be upended! I am interested in the idea of gravity as an aether inflow, and am looking for something to demonstrate or refute this in the case of the Earth's gravity. Cheers.

Do you have a reference for this idea?
