If simulation is possible, we could upgrade reality to 4D
(sh.itjust.works)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
What exactly are you defining the 4th dimension as...?
Another space dimension, which has same relation to our three X Y Z dimensions, as third dimension Z relation to X Y.
For clarity the word is perpendicularity. A 4th spatial dimension would have to be perpendicular to all 3 other spatial dimensions.
Ah I understand you now, I was confused about you not specifying space when referring to 4D, mb.
