In your reality, your space moves through time. But in the realms of the Spime, it's the opposite ways around. That's why Doom-Stone has saloons and Stassius has hyper-crafts.
And while your realm may have frontiers that are left to explore (oceans, stars, first dates, etc), this guide hopes to prepare you should you find yourself underneath a reality you don't recognize. Which, to be honest... once that happens, it starts to happen a lot.
And the next thing you know, you're jaunting, finding there are lots of ways to traverse realms, but how about we save all of those details for the "SPIME" entry of this guide.
See, length and width aren't 2 dimensions, they're only 1! You can't measure one without the other, and that's the flaw in the physics of your rendering, er, I mean reality*.
See in the SPIME, X AND Y are one dimension, Z is the second dimension, and time is the third! Doy!
So dimensions can mean spacial dimensions (of the body), time dimensions (of the mind), or energy dimensions.
Yett everything, and we mean everything, is fractals. A gorilla in the Easton zoo exists in a different reality from the caterpillar it's watching. Maybe there's something to that. We'll get back to you.
