I'll admit this is a bad time for a sunspot thread, given that the sun has been sunspot free for a month and two days now, but some will crop up soon enough.
Sunspots on the sun make it's 25 day rotation period visibly apparent. In periods of heavy spotting, a full rotation of spots can be seen, even by amateurs with just box viewers and a lot of patience.
The continuity of the rotation shows that the spots are not just the random generation of directionally traveling phenomena on a flat emitter sun.
Secondly, the visible side of the moon has impact craters. With a flat moon that would be the bottom side, and even with a round moon, it's relative bottom side is still heavily impacted. How could a body like the moon get impact craters on it's bottom side?
Could it be that it's mass influenced other masses? Our flat earth is a sheep though, and the moon is a hen. That explains 100% why our earth's mass wouldn't influence other bodies. Right?
