@KumelMeelis Yeah, right, because eyes are perfect and have never deceived us...
The curvature is barely noticeable from a person's height (you would have to be able to notice a rat on the horizon).
@ThisIllusion7@Luna76909186@DSL1912 The Moon does indeed orbit the Sun. However, since it's relatively close to the Earth its orbit is wavy.
By the way, have you heard of the Cavendish or the Shiehallion experiments?
@666BenHur@Its_Stationary Do you know how simple seismografs work? (it's in the wikipedia page, go check it out) How could they detect Earth's rotation?
