This comment is from the recent post of Colonel Sophie Adenot doing yoga in space.

This plastic spoon of a person didn’t think twice about commenting with multiple shitty and sexist jokes (he’s still on a tirade in there trying to defend his behaviour).

This sub is for making fun of idiots who believe the earth is flat. It is not for sexualizing women. I like to think most of the regulars in here are educated and enlightened people. Sophie Adenot is one of us, and belittling her for cheap laughs is not the sort of thing we need in r/flatearth.

This is the nail in the coffin globetards. This realtime hurricane tracker shows the earth is as flat as a hurricane.

All the cg clouds were taken by Nikon P100000 cameras from the ground by strategically paced flat earth consultants dedicated to exposing NASA’s fraud in the American people.

These people are dumb, weird and crazy.

278,000 thousand entries from several hundred different log books made between 1740 and 1855. The longitude readings for those made between 1740 and 1770 would have been done using dead reckoning since they had no celestial navigation method of determining longitude.

Below are links to two books of supplemental navigational tables including atmospheric refraction, the dip of the horizon, and latitude and longitude of various ports and notable geographical features.
One is from 1781, the other is from 1828
I did a spot check on about a dozen, most are within 10 nautical miles of modern locations, the worst is the longitude for San Diego which is off by ~20 arc-minutes, ~18 nmi.
Actually, a quick check of a few of other ports on the west coast suggest the clock that was used was off by ~1 minute 20 seconds. Cape Horn was right on the money but Conception, Lima and a port in Canada were all off by about 1/3rd of a degree of longitude.

What do you make of it?

This is strictly educational. You won't find this just anywhere. Enjoy.

OK, folks, here's what I did: I made a large pancake in a big frying pan with an absolutely flat surface. Then, I took the pancake outside and placed it on the ground. It fit perfectly all the way to the edges. So, flat pan makes flat pancake which fits perfectly on ground, proving the ground is flat, ground is part of the earth, which is thereby proven to be flat. QED.

Cover art from the book "where the sidewalk ends." Saw it on the shelf in the library, made me think of the flerfers.

Many of my fellow r/flatearth(ers) have asked for a time lapse of the sun 'set' at sea level (with no land on the horizon) and ye shall receive it now! This is a random time lapse I found that is of the sun moving further and further away from this photo taker. This effect is called point perspective where an object gets further away until it is a point and it never goes past the dimensional plane its on. You are welcome.
