OK, this has nothing to do with space, we are on earth. According to the ball earth, North pole is north, south pole is south, northern hemisphere, southern hemisphere. From the equator the North pole is up, the South pole is down. Therefore, if someone is standing on the north pole upright, the person on the south pole would be standing upside down, even if you turn it around, south on top, north on bottom, on the ball you will still have one person upright, the other person upside down. Get a basket ball, hold a chess piece or whatever, place it on top of the ball (North Pole), then get another piece similar (say 2 kings) Hold the other king at the bottom (South Pole) you will see one of them is upside down just like on the globe! Gravity they say holds you down, but one person will still be upside down! But here's the thing, The earth ain't a globe like we've been thought, it's a flat plain, that's why nobody is upside down. Why would they lie, I know the answer but it's beyond the scope of this. Gravity doesn't exist, it's about weight and density of objects against the air around us. For example, if an apple falls from a tree you think gravity pulled it down yes? OK, So how is it that anything heavier than air will fall to the ground, but balloon filled with helium will rise up, what's the force pulling it up? Anti-Gravity? I don't think so. Helium is lighter than air so it rises, so does smoke, anything heavier or denser than air will fall, anything less dense or lighter than will rise. If gravity existed and was so strong to hold upside down buildings on earth and people, how come it can't pull down a tiny butterfly? Gravity is so strong it can pull the worlds heaviest objects the ground, but yet can't pull down a hot air balloon, or a tiny fly or a tiny bird, how do they fly, their wing pressure force is greater than gravity? LMFAO! It's weight and density, not gravity, the earth is not a ball it's flat! No globe means no gravity, means no space travel, means no satellites, means no ISS. It's all a hoax and it has been proven. Find me a real picture of a satellite in space, not a CGI one. A REAL ONE! Do the research, Earth is flat, loads of evidence, you-tube is your friend!
