The Sagnac Experiment was designed by Sagnac in 1913 for the specific purpose of detecting the aether and was successful in doing so. The result being the Sagnac Effect and empirical proof of the aether.
I know you won't read it notnatman, but for the sake of others who might be slipping into a like mindset, here's some interesting reading:
https://briankoberlein.com/2015/08/11/does-the-aether-exist-hint-no/This article states that the Sagnac experiment proves the aether "A shift in the interference pattern is exactly what the aether model predicts." A direct quote that contradicts the title of the article proves it's misleading and intellectually dishonest.
It then tries to whitewash the result by claiming it didn't disprove relativity because it (relativity) doesn't apply to rotating systems. Dufour and Prunier totally blow this argument out of the water by proving the result are in fact not consistent with relativity:

It's no wonder you believe in a flat Earth, your reading comprehension is abysmal at best or blinded by your one-eyed subjectiveness at worst.
Here's a key point taken straight from the article that you conveniently ignore constantly when the Sagnac experiment is discussed:
"...the Sagnac experiment is
inconclusive, since it agrees with both the aether and relativity models."
