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."
You are arguing facts with a lying troll. :/
We proved the earth was a globe
hundreds of years ago. There is no debate anymore.
These type of threads just serve to feed attention to a very lonely man.
