So I was listening to this catchy has hell song the other day: Willow Smith - Wait a Minute (the 6th dimension song) - https://www.youtube.com/watch?v=pC4RRPY32RY
And I said to myself, "Just what is the 6th dimension?"
If you've ever wondered what is past the 4th dimension (time) - in short, it's alternate realities.
a) DI implies "two"... https://www.etymonline.com/word/di- so it doesn't matter what number is suggested beforehand.
b) Dimension implies mind (mens) divided (di) within action (ion)
There can be only one reality (all perceivable) for each alternation (ones perception) within...unless ignored for suggested amounts, which imply fiction.
10-6=4
