Thanks for the explanation, but since you, along with mathematics, agree that there’s a surface, there should be a normal/perpendicular, and you can get more or less close to that surface, i guess i just can’t wrap my head around it, it’d mean that the hypersphere is on both sides of its surface ?
I’ve read elsewhere that the universe would be this (hyper)surface, i wonder what the surface of a 5d-sphere would look like then.
