Anyone care to take on these challenges? 1 - No motion of the Earth is felt - when a helicopter hovers why doesn't the earth move or a plane flying straight never corrects for the curve? They will answer "gravity" and yet teach the coriolis effect with a bullet being shot....again I say No motion of the Earth is felt, for you will feel the earth move when it does it's called an earthquake! 2 - No measurable curvature anywhere - get a camera with a good zoom and everything comes back into view...You can see with your own eyes things over 60 miles away...Do the math, 8" per mile squared. (GoPro [fisheye] lenses used to fake the curve of the Earth. No one has ever circumnavigated the Earth from north to south –check out the Bolivian salt flats missing curvature.) 3 - Horizon always rises to eye level (Water always seeks its level and it makes up 71% of our Earth.) 4 - Gravity is nothing but electricity (Density, buoyancy, and electromagnetism are better explanat...
