##### Flat Earth Debate / Earth's Curvature on a Smaller Scale
« on: February 20, 2021, 03:00:39 PM »
Some people of the F.E.S ask, "Why can't I look across an Olympic-sized swimming pool and see curvature?". Here's why: there is curvature, but very small, small enough to not be seen with human eyes.

Earth curves at around 8 inches per mile, which means that for every mile, the Earth curves around 8 inches. Dividing 8 by 63,360 (number of inches in a mile), we get 0.000126 inches per inch (rounded). 0.000126 inches is 3.2 micrometers, or 3.2 millionths of a meter. So for every inch, Earth curves 0.0000032 meters or 0.000126 inches. This means for every foot, the Earth curves by 0.001512 inches (0.000126 multiplied by 12), or 38.4 micrometers (0.0000384 meters). An Olympic-sized swimming pool (my example for this) is 164 feet in length (long-course). Multiply 0.001512 by 164 and you get 0.247968 inches, or 6,297.6 micrometers (6.2976 millimeters, or 0.0062976 meters). That's very small. For comparison, a US dime is 0.705 inches in diameter (17.91 millimeters, 0.01791 meters). So no, you wouldn't really be able to see a curvature in an Olympic-sized swimming pool.

Too long, didn't read: An Olympic-sized swimming pool will curve at less than half of the diameter of a US dime, not really visible.

##### Flat Earth Debate / Lunar Eclipses?
« on: February 18, 2021, 03:45:49 PM »
Attached is a timelapsed video of a lunar eclipse. You can see Earth's shape on the moon as the moon passes behind the Earth. Tell me, how does that work if Earth is a flat disk? On Flat Earth day-night models, the sun and moon are always shown opposite of each other, which can't be true because you can see the moon in the daytime sometimes. So tell me, what's going on? When does the Earth get between the sun and the moon on those models?
And don't tell me that this video is CGI-animated, because you can tell by the jittery camera that it was filmed with a real camera and that it is not CGI.
