>>17667427We observe globe Earth, and only globe Earth is consistent with all related observations such as two celestial poles, northern and southern stars, southern hemisphere distances, sun/moon rise/set, visual and radio line of sight limitations, day/night in Antarctica, etc, etc. We can detect Earth's rotation with ring laser gyroscopes, and we proved Earth's motion through space with the COBE satellite.
GPS alone proves almost every aspect of globe Earth including shape, size, rotation, gravity, space, satellites and orbits, and time dilation. And there is FOSS GPS software which runs on SDRs so that anyone can prove it all any time they wish. The only thing GPS doesn't prove...absolute and not just relative motion through space...was proven by COBE.
Nothing we observe is consistent with flat Earth except the immediate, unexamined observation of the land around us, which appears flat due to scale. The moment you actually think about sun/moon rise/set/transit, or the stars, you realize Earth has to be a sphere. Which is why even the ancients understood this.
All flat Earthers can do is lie, manipulate, and twist observations to try and make them fit with flat Earth. They create copes for different observations that are incompatible with each other. When you call them out on it, they run away crying 'we have no model!' And there are plenty of observations for which they have no cope. They will either ignore it (Polaris) or outright lie about it (claim a proven rectilinear lens is a fish eye).
Flat Earth is pushed by talmud jews, glowies, and con artists. The end result...which is the goal of glowies...is to discredit unrelated conspiracy theories and forums which may have some truth and which threaten the narrative.
