...now he comparing astromechanics with B3D...so B3D is plain proove for you and tons of sattelites who use to take images of planet at same time from different positions (so its obvious its sphere) as well as astronauts is not good enough?? Well boy..far as I know math, sphere is most energy efficient shape as well as shape what has maximum volumen with minimum taken surface...so its not coincidence that all things in nature (read universe) is well optimized on most efficient way, obviously its not coincidence that atoms spinning, planets spinning, your car wheels spining, DNA spiral spinning , etc...same unique signature, so if you are smart enough , you dont have to center of eartj to see is it huge iron superheated core spinning or not..learn from given examples...and i would like to see soap bubble you making by pushing air from your mouth, in shape of cylinder or flat surface...but I'll tell ya..it will be sphere, no matter how much you wanted it to be your flat surface or box...
