hey flat earthers, how do you explain that a model based on sphere earth, gravity, and heliocentric perfectly predicts all eclipses : https://en.wikipedia.org/wiki/Jet_Propulsion_Laboratory_Development_Ephemeris

@Derek Nelson why can't it be proven

@Gray. i liked your performance on 24/7 the other day

did they ban you?

they didn't ban you?

i thought i saw them ban you

@Derek Nelson the gravitational force has been direclty measured

@Gray. how the helld you know

seriously

'obvious' but how?

@Gray. how do you know mine

@Gray. lol who the eff are you

i don't troll i have the vectors of attack that put them in a corner , by their own words

@Gray. gsus, you call me a troll and say you have logical arguments, and you come up with that?

@Derek Nelson so the ISS is in orbit, just in orbit of the flat earth, and is using a fisheye lense making the flat appeared curved

@California Nightmare no it hasn't where

@California Nightmare there has been no such measurement

show me

@California Nightmare that assumes the laser travels in a straight line through the thick atmosphere, how was thsi verified

show me the 9 mi long straight edge reference that was used for this

until then it's no different than eratosthenes assuming parallel sun rays

@California Nightmare lol i stumped you

@Gray. damn good move

@California Nightmare all making the same assumption

many have done the eratosthenes, does that mean the assumption of parallel light rays is accurate?

@California Nightmare only with your glaring assumptions of a laser travelling straight

@California Nightmare oh lol i love this one

in taht last image, are the angles the same, a1

crickets, as expected

b/c those angles ARENT the same

@Gray. See how this works

Take these skills and use them elsewhere

@California Nightmare pffffft

except those angles aren't the same

want me to prove it?

@California Nightmare i can prove you're wrong about those angles being the same

and thus when we measure these shadows we can see which of those cases it agrees with

@California Nightmare no they don't wanna see how

take a1 and move it up the globe until it's at the pole

the angle will be 90 deg

but on the flat plane you could never get that

thus the two angles must be different in teh two cases

saying "nuh uh" doesn't debunk me

@Derek Nelson yes but measurements of shadows at various latitudes eliminates any possibility of a flat plane local sun

@California Nightmare interesting

maybe flat earthers should do this themselves

@California Nightmare can i get a PDF about spaceflight too, and show you taht?

@California Nightmare your claim that the shadows dont' tell us anything is wrong

and all you have now is a repetition of "you can't tell anythign from shadows"

@California Nightmare how do ppl do the vendee globe race if there is an ice wall
