>>14942424What you see there is just slight distortion due to the camera and perspective and light difference etc. it's not the curve of a ball earth, and the horizon is still at eye level.
You have to know how much curve there should be first, but you guys don't study this.
Look up how distant the "curve" really is. At the beach the horizon should be physically at about 3 and a half miles. Yet we can see way further, and people are doing tests with lasers over 30 miles away, directly over the water, and they can see the laser 30 miles away.
