Science admit they don't actually know what gravity is. Still they could prove how it works. Whether it is working perpendicular to a flat earth or perpendicular to a imaginary "center of gravity" in the globe. I realized it would be very simple to prove how it works. Which gave me this conundrum: "If it is very simple to prove that gravity, whatever gravity may be, is pulling objects towards Earth, in a direction perpendicular to a point in the center of a globular earth, towards the center of Gravity, how come no-one has done so yet?"
Space is distorted near objects and that's what's pulling you or anything else (gravity) ta daaaaa
That it basically like saying that Unicorns do exist because nobody ever provided evidence they don't.
