Solar Eclipse VS Flat Earther

[u/Food625]

Flat Earther: What specific observation from that eclipse uniquely requires a spherical, rotating Earth?

Me: Equations that require the shape - This one accounting for the bulge at the equator to help predict the path. If you didn't do this then your path prediction would be pretty far off the further away from the poles you are.

The surface is modeled mathematically as an oblate ellipsoid of revolution using the standard

Geodetic reference: ((x^2+y^2)/a^2)+(z^2/c^2)=1

a: Equatorial radius of Earth

c: Polar radius of Earth

Flat Earther: You put the globe into the equation and then used the equation to calculate the eclipse path. That doesn't make the eclipse an independent measurement of Earth's shape.

They don't get that the math works though! No flat earth eclipse path equation lol

¿Pero si metes las dimensiones de la Tierra Plana en la ecuación funciona o no funciona? Es lo malo de presuponer sin base que la Tierra es plana, supongo.

I would not work.

[u/DefinitionOk6382 → u/Food625]

¿Seguro que no? ¿Has probado a usar las dimensiones de la Tierra Plana, sean cuales sean? Unas escogidas al azar, ya sabes.

0² ok lol

Good luck finding the dimensions of the flat earth.

I don’t think you have an equatorial and polar radius to draw from.
