Hello, I've noticed the flat earth issue/debate is often discussed here on CI. I know nothing about it, so I'd appreciate some guidance. Can someone point me to specific, detailed resources covering the basics of how spherical earthists have deceived the entire human species for hundreds of years? I'm more interested in the how and the why than mathematical equations. Is there concrete evidence? What is the foundation for the thesis?
I can only guess that the diabolical is at work in the deception, as with Darwin & the death cult of evolution.
I'm sincerely curious. This is not a troll.

Here are some resources, mostly easy to verify visual evidence, to get you started:

Thanks, Dankward. Much appreciated.

These are by far the weakest and most pathetic globe earth arguments out there, and yet you keep posting garbage like this ... even after it's been pointed out to you.  You are completely dishonest.

Did you watch that group from South America that did real experiments?  They had a top surveying firm use precision GPS equipment (accurate to within centimeters) to measure whether buildings about 1800 miles away from each other actually lean away from each other as they should on a globe.  Buildings were at the same elevation and similar heights.  They used directional radio waves that are not subject to refraction that could not work through earth curvature.  They also built their own specialized laser.  They also used precision GPS and geodetic surveying equipment to prove that a large body of water was in fact flat.  They had engineers and professional cartographers accompany some of these experiments, men who were skeptical of flat earth at the outset but then had to concede based on the experiments.  They also measured sun paths and sun angles by setting up cameras around the world, and they found that these were not consistent with a spherical earth.

Yet you pull out these dumb populast globe "proofs" that are the weakest out there.  That picture of the cards disappearing on a curved surface is stupid.  Nobody doubts that they would disappear like that on a curved surface.  So what does that prove?  In fact, however, Flat Earthers have demonstrated that the same thing happens on a FLAT surface due to perspective.

You keep posting these absurd pictures of one or two things that appear to be cut off, but it's been proven by Flat Earthers that this CAN be due to atmospheric conditions as well as the limits of whatever optics are being used.  Flat Earthers take measurements, explain which optics are being used, etc.  But the Globe Earthers simply dismiss them as refraction.  But then you post random pictures and pretend that refraction doesn't exist.  It only exists for you when pictures indicate flat earth.  Black Swan has never been debunked, simply because you CAN take a picture of the platform under certain atmospheric conditions where it does appear to be cut off.  Black Swan picture not only showed both platforms but you can also clearly see the horizon line behind the second platform.

Flat Earthers have demonstrated that sometimes you can see the whole thing and sometimes you can't ... from the same location on a different day.  There are only two possibilities:  there's atmospheric conditions and refraction on the "globe earth" days or else it happens on the "flat earth" days.  Globe Earthers simply assume, but never prove, that the refraction only magically happens when there's a picture that proves flat earth, but couldn't possibly be there on the "globe earth" days.  It's completely dishonest, and you discredit yourselves this way.  Meanwhile, the FEs try to be honest, taking all the measurements, etc.  There's no intellectual honesty among the globe earthers, just a bunch of lies and fake videos from the space agencies.

Another place where the Globe Earthers shoot themselves in the foot.  They claim that due to the earth's rotation, the earth actually turned into an oblate spheroid due to the centrifugal forces involved, and yet these same forces have zero effect in terms of displacing the water on the earth.  Due to these forces, you wouldn't have a consistent sea level around the "globe" but would have the oceans bulge at the lower latitudes.  Oops.  Centripetal forces should be higher at the equator, and so the same mass at the equator should weight a bit less than at the poles, but experiments have actually shown the opposite, that they weigh a tiny bit less closer to the north pole.

This confirms that this type of equipment is accurate to within centimeters.

Looks similar to what they were using.



If I ever hit the big-time, I'll get some of these and conduct my own tests.

These devices don't work without satellites.

Hard to say what these "satellites" are.  FE theories include a combination of land-based towers, and there are in fact many satellites that hang from helium balloons, etc.  These devices are known to work though, with HOW they work being a separate consideration.  US military, long before the age of satellites, had a system known as LORAN that used towers.  Two towers could provide very accurate positioning to sea vessels a thousand miles away.  That's actually another pro-FE argument.  These things required line of sight and could not have worked over curvature at the distances it did work.  Some FE proponents do believe that satellites can rotate around on their own, but dismiss the explanation of how they stay in "orbit".  That's actually the belief of the group that produced the video above.

Always the argument shifts from ground-based, very clear experiments to postulations about the sky, moon, satellites and "space".

Is Prof. (((Dave))) a CI poster now?

I am just wondering why Lad would rely on U.S. military data and satellite technology to prove flat earth.

Is Prof. (((Dave))) a CI poster now?

Speaking of "Dave," he's been shredded by scientists regarding a number of non-FE-related subjects where he showed himself to be ignorant ... and yet was extremely arrogant about his comments anyway.

This gentleman here very politely makes Dave look like an idiot:
