Concave earth?
If we can sail across the concave surface then we know how big the sphere actually is, we could confirm this concave ball size with a laser beam shot across the universe that lands on the other side of this concave planet, that is a far simpler experiment. Seems like a terrible theory that will fail with two seconds of logic.

The biggest deception is light itself. Namely the properties of light. Here's a kicker: in vacuum light does not travel in straight lines. Instead, light bends along the concave curvature of the Earth itself, making it seem as if the horizon was flat while it really is not. That's why we must discard all experiments utilizing light --- because we cannot trust light. There is plenty of evidence for the bending light theory, there's even science grade proof that is carefully kept away from the public education.
As mr. reptile said above "satan is deception". since satan = lucifer = bringer of light, light cannot be trusted. Light can be used for deception. This is why all the new age religion bullshit is utter and total bullshit --- it always speaks of light as something good while in reality light is all about deception.
Well a laser pointed straight up will be bent equally in all directions by the concave earth, therefore traveling straight to Japan.... So ignoring light experiments because light bends is just selective reasoning.
The concave earth would also be teeny, tiny in comparison to even the ability of a spacecraft to travel in a single day. The orbit of the moon itself will not fit in the space offset by the size of Earth's concave inner hole. I am sure you know all of this, so the only way a concave earth would ever work is that everything we know about space and time is completely wrong. The moon really is a tiny little ball in the air, and every foot away from concave planet earth surface shrinks you in size dramatically. Usually when you have to dismiss every known aspect of physics, space and time, you can bet you are on the wrong side of logic.
