Thork is correct that people would never believe any experiment we did. The best we could hope for is that people replicate it. Thork is also right that the experiment needs to be as simple as possible, within the reach of a person, which is why I suggested observational tests of EA which look for curving phenomena.
There are ways to inspire confidence with any test. The best way to do that would be to:
- Do it ourselves first
- Find a public figure such as a physics teacher interested in performing the experiment to "double check"
- Maybe send the devices to different RE/FE people who hopefully would not steal or damage the equipment (under escrow if we don't know them?)
Anyway, not that it would prove anything since all of those people could still be planted FE shills, but it would at least encourage a science group or classroom somewhere to do it, which would in turn possibly encourage a real scientific investigation of the effect. I have my doubts that science will ever actually go near anything FE since they are not performing more comprehensive versions of the water convexity tests, which now number into the hundreds in the wider FE YouTube community, and which can show that one can see further than should be possible. I think they just accepted that this effect exists and have opted to call it an illusion rather than to perform more controlled versions.
Repeated tests are generally enough to convince people that the effect exists. A result encourages others to also investigate the event, so nothing would be a waste.
edby's idea of a journal is interesting and deserves some thought.
On the UA Experiment to edby:
Universal Acceleration suggests that the gravitational variations by latitude would not exist, correct. It also suggests that variations by height would not exist (if we ignore the Celestial Gravitation hypothesis that is sometimes invoked that gives the celestial plane a gravitational field)
There are doubts that the existing gravity by latitude experiments with precision scales are valid since they were not done in a vaccum chamber. It is possible that an environmental property gradient at different latitudes is affecting the device (as discussed on
https://wiki.tfes.org/Weight_Variation_by_Latitude ). At the bottom of that page there is also a link to Time Dilation by Latitude, which uses precision atomic clocks, and shows that time does not dilate by latitude according to the latitudinal variations of the Earth. It is explained away with the Equivalence Principle. That is reason enough for me that the latitudinal variations are questionable.
The scale experiment in a vaccum chamber is one that is simple enough that a community project could be centered around it. Vaccum chambers and scales accurate enough to test this are not expensive. But we would need to figure out how to put a scale into a vaccum chamber and get accurate results, which I suspect will be the actual challenge (and may doom it). Taking it to a different height is something that can be done by a single person. Taking it to a different latitude could be timed to coincide with someone's vacation, or sent to other people who live at different latitudes like the Kern the Gnome experiment.
As far as I can tell from numerous searches, a vaccum experiment with a scale at different latitudes and heights has never been performed. I am sure that you have also searched for these kinds of experiments in your efforts to debunk UA. 300 years ago scientists did the scale experiment exposed to atmosphere and decided that the fraction of a one percent difference they were seeing was due to gravity. That same experiment was then repeated over the years.
I think you already know about what the Wiki has to say about gravimeters and what it is actually testing. It would be nice to have reference of a simple experiment that doesn't depend on assumptions about a complex product full of algorithms and inputs, and which may be only indirectly testing gravity based on some of the statements given.
To Thork on his simple experiments list:
If you can think of anything, sure. RE has spent 3000 years making explanations for any simple experiment that someone can perform. If you change the nature of space and time you can explain why a shoe drops at the same rate as a penny, despite the illogical nature of that since it takes more force to physically move a more massive body through space (ie horizontally, pushing a bowling ball and a marble yourself). My opinion is that they are very adept at excuse making.
The experiments would need to test those excuses, or catch the celestial bodies doing something that should not be possible under straight line geometry and force them into their "lines curve because they are projected/wrapped on the celestial sphere" explanation that is eventually trotted out.
