The best you can do, I think, is to get a lot of detail about what he believes and try to find a contradiction in it. I'm not sure a setting sun will convince him the earth isn't flat as they do seem to come up with some odd excuses to combat it.Īnd they'll keep coming up with odder and odder excuses, even ones that are patently ridiculous, rather than give up this idea that makes them feel like they're special because they know "the truth." If the gas was equalizing on the earth, then this would not be possible.įeel free to ask me anything else you are confused about, and I will be happy to help explain it to you. The atmospheric pressure is objectively less due to the pressure gradient. If you took the same box in an airplane and accelerated downwards proportionally to the acceleration of gravity, then you could simulate zero g, and you would notice their is no longer a pressure gradient.Īnother incredibly simple experiment is to travel to a higher elevation. This would not be possible without a downwards acceleration. They will separate based on their density. Another way we know how pressure gradients exist is that you could put two gasses in a box. Notice how the gas is then forced to the rear facing side of the box. Because of how small this change would be due to the difference in your r value between the bottom and top of the container, it would be impossible to notice without sophisticated measuring tools.Ī better experiment would be to put gas in a box in a car and accelerate. If you were to put gas in a physically solid container on the surface of the earth, it would actually be slightly more dense at the bottom. You are clearly not understanding gas dynamics.
