Four dimensions (split from The meter-second)

Recommended Posts

I was wondering what the fourth dimension might be, if a point is 0, a line 1, a square 2, a cube 3 dimensional. What would a 4 dimensional "cube" look like? My thinking went that if a metre cube sat in the same position this could be it. But would that be a cubic metre x second? So I googled metre second and found this link.. so if you know what a four dimensional cube looks like, let me know.

This appears to be completely off-topic. Anyway, replace each of the faces of a cube with cubes (I know, not possible in three dimensions): https://en.m.wikipedia.org/wiki/Tesseract

Are you looking for a physics definition, such as time in the theory of relativity, or a mathematics definition, such as defining points by number quadruples?

It is exactly as you think.

A little deeper into this rabbit hole of "higher dimensions"
