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.jeremyfiennes said:The original interferometer experiments -- Michelson-Morley, Miller, etc. -- were all done parallel to the Earth's surface.

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.

A vertical interferometer experiment is a scientific experiment that measures the speed of light through the use of a device called an interferometer. This device splits a beam of light into two beams, which then travel different paths and are recombined to create an interference pattern. By measuring this pattern, scientists can determine the speed of light and test theories about the nature of light and the properties of space.
The Michelson-Morley experiment was a famous experiment conducted in 1887 by Albert Michelson and Edward Morley. It was designed to measure the speed of light in different directions in order to detect the existence of aether, a hypothetical medium through which light was thought to travel. The experiment failed to detect any differences in the speed of light, which challenged the prevailing theory of aether and paved the way for Albert Einstein's theory of relativity.
The Miller interferometer, also known as the ether-drift experiment, was a series of experiments conducted by Dayton Miller in the early 20th century. It was similar to the Michelson-Morley experiment in that it aimed to detect the existence of aether by measuring the speed of light in different directions. However, Miller's experiments used a rotating interferometer, which he believed would be more sensitive to the motion of the Earth through the aether. The results of Miller's experiments were inconclusive and have been heavily debated by scientists.
In addition to the Michelson-Morley and Miller experiments, several other experiments have been conducted using vertical interferometers. These include the Sagnac effect, which measures the rotation of the Earth using an interferometer, and the Kennedy-Thorndike experiment, which aimed to detect changes in the speed of light due to the Earth's motion through the aether. These experiments have all contributed to our understanding of the properties of light and space.
Vertical interferometer experiments have been instrumental in shaping our understanding of the properties of light and space. They have played a crucial role in debunking the theory of aether and have provided evidence for Einstein's theory of relativity. These experiments continue to be conducted and refined, providing valuable insights into the fundamental nature of our universe.
