Where is the flat-earth evidence for “water seeks its flatnessâ€? Oh that’s right — a “youtube scientistâ€, did an amateur experiment with a laser and a boat.
Taking accurate measures, enough to show 8in of difference over 1 mile, of the surface of water is a challenge. Amateur laser experiments on boats are not accurate enough, as they fail to estimate the curvature of the laser light due to atmospheric refraction. As anyone who has ever observed heat haze on hot asphalt, or the air behind an airplane engine, has seen evidence that temperature differences can distort light. Temperature changes, like warm air over cooler water, on a clear summer day, can bend light — even laser light.
I’m stupid enough to “debate†a flat-earther. I found it funny that, while you seek flatness, I have shaped water into the same shape as the earth many times as a kid.
Google “water in the space station†for some photo and video evidence of water very much not seeking flatness but taking a very convex shape.
Water does not take a flat shape. Show me an experiment or evidence that indicates that. You have nothing.
