english: But if we were freely falling through the space, even without this helpful grid, we might be able to paint it ourselves, because we would notice that we traveled along straight lines, undeflected straight paths through the universe.
non_english: Keby sme však vesmírom voľne padali, dokonca aj bez tejto pomocnej mriežky, možno by sme ju mohli nakresliť sami, lebo by sme si všimli, že sme išli po rovných čiarach, ničím nevychýlenými priamymi cestami vesmírom.
