All aboard the Flat Earth cruise – just don’t tell them about nautical navigation

Sounds like it ight be a fun cruise. A few eccentrics are much more interesting than normal people.

Forget about GPS. Just try sailing across any ocean with a compass, a chart, and a chronometer (technical name for a marine clock), the way everybody did it before GPS was invented. The whole thing was, and is, based on spherical trigonometry and wouldn’t work if the earth wasn’t an oblate spheroid.

I believe they sent out a flyer stating people from AROUND THE GLOBE will be attending.

The course of ships and airplanes on long voyages is never straight because there are no straight lines on the surface of a sphere. The shortest distance route they follow to their destination is described as the Great Circle Route. Except for a limited and specific set of circumstances (such as sailing a route coincident to the equator), the Great Circle Route will appear to curve when plotted on a flat map.

The great-circle distance or orthodromic distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior). The distance between two points in Euclidean space is the length of a straight line between them, but on the sphere there are no straight lines. In spaces with curvature, straight lines are replaced by geodesics. Geodesics on the sphere are circles on the sphere whose centers coincide with the center of the sphere, and are called great circles.

All of which pretty much puts the lie to the Flat Earth nonsense.

Dismissed out of hand as part of the Great Conspiracy. :-)

Probably more than half really don’t believe it. It’s just a mental exercise.

*did you see this one, ping ?*

Imho they must have some good drugs.

Thanks Simon Green.

Ah, there are a few still around, but I haven’t seen them on this type of posts since the zot.

Lol!

Out of all the logos they could have picked
the United Nations chose this...a flat Earth image.
(made famous by Gleason in 1892)

Also known as an azimuthal equidistant projection map.
Curious, wouldn't you say.
Nothing pleases power mongers more
than rubbing the truth in your face
without you even knowing that it's being done.

[philman_36]

Perhaps an Antarctic cruise could be done. They could keep the land to port and see if they
have to steer to starboard to avoid running aground or into the 100-150 foot tall ice walls there
or to port to keep abreast of them.

The Earth is Flat!
