Gravitational Wave Detector
This type of detector, I believe, can be constructed in a relatively economical manner. The fiber optic links could be obtained from a local phone company. Stable frequency lasers would be placed at the ends of each fiber link. An Optical Spectrum Analyzer placed in the middle would detect the frequency variations of the lasers, and record them for later analysis. These recorded results could be analyzed by the same processes used in other gravitational wave detectors, such as LIGO.
You may also view the patent application for this gravitational wave detector (#2586101) at the Canadian Intellectual Property Office.
To thoroughly verify the inflow predicted by ether theory, however, would require that at least two detectors be built on opposite sides of our planet. The signals from these two detectors could be recorded locally, and later brought together for processing. If a gravitational wave is detected, a comparison of the signals from these detectors should show an inversion that is similar to the one illustrated in Figures 36 and 37.
