I truly like most of it what he his explaining, however when come about flat earth he just got to be out of his mind. The way I see our human kind doesn't have even basic foundation to understand the world they are living in. The way this guy question things it's just shocking over and over asking for curvature, does he really understand larger are the planets less likely would be to notice the curvature, plus if the planets surface is not proportional from the center to the surface than you have another issue there. Wow I'm fucking truly shocked, Well I will say one thing if US government they don't hit the brake from their global ambition, human kind never will leave from this planet to another solar system, before Nazis took over this country, US was peaceful nation, not today. today US uses sneaky tactics name of democracy take over other nations the way they did in eastern European countries, just like anaconda swallowing the whole nation in one shot, creating chaos any part of the world desires to them. I will explain my position very clearly I'm standing for whole entire human kind, if people truly they want to understand how our universe works and how people can travel out of our solar system I want to see peaceful earth that is my bottom line. This earth will support life forms another 300 more years after earth loses magnetic flux things will change completely here on earth, even though earth will lose magnetic flux before that, we know already earth is losing flux rapidly.
