The point at issue was whether Copernicus had simply put forward a mathematical theory which enabled the calculation of the positions of the heavenly bodies to be made more simply or whether he was proposing a physical reality.
Ang punto sa isyu ay kung Copernicus had lamang ilagay sa harap ng isang matematiko theory na-enable ang pagkalkula ng mga posisyon ng langit katawan na ginawa mas lamang o kung siya ay minumungkahi ng isang pisikal na katotohanan.
