      Time is a 4th dimension when talking about spacetime, which assumes three dimensions of space and one dimension of progressing time.

      In geometry, a 4-dimensional object can be projected as a 3-dimensional shadow.

        Yeah, that’s basically what I was referring to. Everything I know about dimensions, I learned from Doctor Who, Hitchhiker’s Guide to the Galaxy and Donnie Darko!

      I like to work from the assumption that there’s nothing magic about the three dimensions we live in aside from the fact that it’s how it is, so any higher dimensions would work just like the three we already have, which are identical to each other just in different directions.
