your not even making sense at this point , we can see ships go over the curve , but we cant see the curve , good point, very scientific. your a mad man if you claim to see a curve with your own eyes lmao
on a ball earth , wouldnt the curve affect the angle of the structure thus making it lean if its 20miles away? , maybe a 1% tilt? , which would scale the higher it goes from ground level? and light travels in a straight direction , MEANING , the lights would be traveling upwards,at that distance , wouldnt u think this abnormally would be visable? no? on a ball earth that lighthouse would be under the horizon , the same horizons that makes ships disappear....unless you have a curved line of sight , your theory is garbage
gravity is a theory , density is reality.
Its a shame , if you put that same amount of energy you got there attacking flat earthers on steemit , you could apply some geniuine research into the subject and wise up a little. I am not taking billions of dollars to shoot up parabolic rockets and make computer generated imagery in the name of science bro. But your seeing curves where there is none , unless your eyes are go pro lenses....
