It has became apparent to me that whenever a video surfaces showing the curvature or something happens that proves that the earth isn't flat it is IMMEDIATELY considered fake by the flat earth community.
I myself haven't seen the curvature, but I do know many people who HAVE on an airplane. (No curved windows, no excuses, it was the curvature). They're my loved ones, and I can trust them. I know with no doubt that the earth is a sphere.
Flat earthers don't seem to want to accept reality... they just want to believe what they want.
I disagree that anyone has seen the true curvature first hand.When looking at a very large ball or sphere, you will always be able to see a circular portion of it. The actual curvature will always be from the point from the surface of the ball in a direct line from your observation point to the centre of the ball, to the circular horizon visible. Do an experiment using a reasonably sized ball and a camera with a macro lens. You will only see a fraction of the surface from a mm away, and now calculate how high that mm would be above the earth. As an example, with a ball with a diameter of half a meter, one mm above the surface would equate to 25.5 km (83607 feet) above the earth's surface, and the distance to the horizon on the earth of 570 km (354 miles), could be compared to a circle of vision on the ball just 2.2 cm in radius.You are not seeing the curved edge of the ball from that height, just a perfectly round ring 2.2 cm away. It is the ring that portrays curvature, but all of that curvature is at he same altitude, , i.e. at sea level, if the viewing point is over an ocean.
Even the ISS, at 250 miles high, the horizon is just 1429 miles away, so you are seeing the horizon as a circle 2858 miles in diameter. The earth's diameter is 7964 miles, so you are only seeing less than a fifth of the size of the earth's surface from one side!
Even at about one million miles away, the distance the DSCOVR satellite is, you still do not see one complete hemisphere of the earth, as about 25 miles will be cut off by the ring that is the horizon. So if you were at a point above the equator, you would not see the poles, but only up to a point 25 miles before both poles.If you want my maths calculations for this, please ask.
You can test some of this if you have a pretty large ball. Draw different colored rings in very small bands on the surface that will be facing you, and place the ball at eye level. From close by, many of the larger bands will be hidden from view, but us you move further away, they will slowly come into view. If you could scale the final band to be the equivalence of about 25 miles wide on the earth (or about 0.4 of a degree or 1/900th of the circumference), and move back the equivalence of one million miles from the ball (or about 125 times the diameter of the ball), you should not be able to see this ring, only all the ones inside it. So the basic point is, if you are looking at a plain ball, do you see the curvature of the ball, or do you see what looks like a two dimensional circle, no matter which direction you look at the ball from?
