>>511323386 (OP)You need to physically measure the surface of water, that's how you can establish whether there is a curve or not. This is the one thing nobody in the "scientific community" will ever do, because it would prove that water is indeed a straight level surface and people just don't comprehend how 3 dimensional perspective works.
You just need a mile or two and build a construction on a beach. Then people can go along that perfectly straight level structure and see that there is no such curve. No curve, no ball. It must curve 8 inch x squaremile, quite a significant curve which doesn't exist in reality. People just cope to not admit that we have been lied to, and that we lived in a universe of human-made lies.
You can also just use your common sense and re-think the globe universe, why do you believe that it is in any way logical or physically possible to be on a spinning ball? spinning around an axis in various different latitudes which must have different intensity of spin, strongest on the equator all the way to zero on the north pole. You would have different weight, less on the equator and more towards the north pole. Nonexistent.
Then we also simultaneously revolve around the sun on an elipse and corkscrew with the solar system disk in another direction around some supposed galaxy. All simultaneous constantly changing physical circular motions. Nonexistent.
Air-pressure wrapped around that ball next to a vacuum. Moon "pulls" some water, but not everything, not humans or any other watery life. The whole concept of this globe universe is just imagination lala land, nothing substantial, nothing physically real. It's Star Wars and Star Trek, cartoons and CGI, and people want to believe in it, like a religion.
Here is where it started
