When the Challenger disaster happened, teachers rolled TVs into the classroom to further indoctrinate the kids.  Do you know that most of the "astronauts" that were "killed" in that disaster are still alive.  Amazingly, 3-4 of them had "identical twins" and the others either slightly changed their names (started using their middle names) and went about their lives (after undoubtedly taking a huge payoff).

It was on YT but I’m not sure where.  A few years ago.

n reply #159 I asked an honest and simple question regarding why the “edge” of a flat has not been discovered, described, nor pictured, given the amount of exploration that has occurred.

I cited explorers such as Leif Erikson from the 11^h century and Columbus, da Gama, Magellan and Elcano from the 16^th century.  To this list can be added James Cook (1773).  Within a year's time in 1820 the Russians Fabian von Bellingshausen and Mikhail Lazarev, the British explorer Edward Bransfield, and the Americans Nathaniel Palmer and John Davis all saw or set foot on Antarctica.  The Norwegian Roald Amundsen reached the South Pole in 1911.  U.S. Admiral Richard Byrd (1888-1957) is another noted Antarctic explorer.

The only answer my honest, sincere, and simple question received was that because of “the treaty”, and no one could be bothered to even cite its actual name, nor when it was signed, nor by how many countries.

The Antarctic Treaty was signed on December 1, 1959 by 12 countries, but did not enter into force until June 23, 1961.  There are now 50 nations that have signed or accept the treaty.  This treaty that supposedly prevents us from finding the “edge of the earth meeting the dome of the firmament” did not come into existence until years, decades, or even centuries after the explorers I cited.  This pretty much tells any thinking and rational person all they need to know about the credibility of the “flat earth fantasy”.  “If” the earth were flat someone would have been to the edge by now.

Here is the actual text of the Antarctic treaty https://www.nsf.gov/geo/opp/antarct/anttrty.jsp

If the earth is round, nothing would be needed to adjust rails for the earth's curvature.

This does not require you to believe the earth actually is round. It's really basic physics.

Draw a circle on a piece of paper. Are all points on the circle the same distance from the center of the circle? Yes. Is the circle curved? Yes.

But I'm trying to explain to you why this is not a problem. They may be other problems with a globe earth, but this isn't one.

A railroad rail on a globe earth lies on a circle on that globe. It is like the points on a circle. Just like all the points on a circle are the same distance from the center, every point on the rail is the same distance from the center of the earth. It is therefore at the same "grade".

Gravity always points to the center of the earth. Thus it is always perpendicular to any tangent to the circle of the earth. Each segment of rail is a short tangent on the circle. Thus a rail along the earth's curve is always perpendicular to gravity. Any movement on the rail is perpendicular to gravity, thus at the same grade.

This silly meme is one of those things that actually kind of makes me lean more in the FE camp:
