well i rediscovered this method to measure earth radius after being banned from the flat earth society for talking nonsenses
i know by personal experience the earth is rounded, most people just know it by blind faith, i meausred it myself
also when you leave the flat stage of the channel the system becomes unstable and freezes
edit:
i wonder how many people on this planet have measured earth radius themselves
with the brainwashing educative system i bet quite few
the oddest thing is i obtained a radius of 600 km
