It just shows how indoctrinated you are. You will never go to "outer space", will never walk on the moon, will never feel the so called spin of the earth and will never witness any curve. Your believe system is more religious than you assume. Stick to stacking sats. Peace.

What indoctrination are you talking about? I'm talking about simple and elementary concrete things that any man with basic mathematics and a stick stuck in the ground can calculate its circumference, and with a telescope worth a few tens, hundreds of dollars you can see a lot of constellations, planets in our solar system where you can see their spherical shape; what you see through the telescope has nothing to do with indoctrination, what you can calculate has nothing to do with indoctrination.
Extraordinary claims requires extraordinary evidence which you will never be able to produce yourself. It needs you to trust a 3rd party "agency" that is deeply involved with governments, the precious fiat system and is basically a sex cult, shooting and exploding dildo's into the air. You may want to digg a little deeper into the history of your favorite space agency.
Regarding math, you can describe pretty much anything you want but doesn't mean it's reality.
but how do you know what reality is without mathematics/physics and simple or experimental observations?
