I was just wondering, if the Universe were a 3-sphere, could you define points in 4dimensions, by using two points in our space?
Is this done?
maybe this is trite, but I thought I would post anyway.

Hi Frog, just my point on a 3D gravity well of a black hole, and no,
you cannot. 4 dimensions ( excluding time, that is) are beyond our
current brain power to understand, let alone define.
Perhaps that is why we struggle so much with the dimensions in
string theory. Aw, we think we know it all, the compexities of
the universe are beyond our current comprehension, but, perhaps
grasping that, we may eventualy understand.
