"You make claims about how aether behaves that seem to answer many questions about our world. Now is the time to test these ideas."
Go ahead. you have access to the same resources as me.
Think about this for a moment though: if I came in one day, and said I'd performed the experiment, and that the results were exactly in line with DET... Even if I provided a few photos of a gravimeter and balloon, and even if I gave altitudes at which jumps occurred, what would that achieve?
Would you actually believe it, or would you just conclude I was lying to promote my model? Would that convince you, or would you remain a staunch round earther and ignore it?
I don't have unlimited funds, and it's quite an investment for me to perform the easier experiment, for zero actual gain.
