you obviously have a bias and didnt even watch the experiment posted . Basically you can model the same experiment on a flat surface and map it to a sphere, therefore it isnt a proof of the round earth. I can just as easily say the earth CANT be round, obviously that isnt a answer or proof .I supposed real scientifically minded folk will look into these experiments , you are not one of those people . Your comment makes no sense, if something is disproven it is disproven , doesnt matter if its a video or not, the math can be applied to 2 different situations. if you cant see the flaw in that then youre just being dishonest
