i would like for once to find a non-analogous, qualitative description of spacetime...i can readily picture the 2-dimensional analogies of curved space but i want to be able to, not picture, but comprehend using something like my normal ideas - or even protracted but logical ideas - about space and time...(adsbygoogle = window.adsbygoogle || []).push({});

start with a 4-dimensional sphere ('hypersphere')...what are the time dimensions of a hypersphere that differentiate it from a 3-dimensional sphere? can we describe such a sphere using 3-dimensions and adding on, qualitatively, the variables of its dimensions in time in order to gain a qualitative comprehension?

i understand this is a very difficult thing to ask, a qualitative, non-mathematical description of 4-dimensions without using 2-dimensional analogies, but i'm wondering if there is still a way to do it?
