Zero spatial or temporal dimensions?
Unpredictable!

Do you still have less than four dimensions?
Too simple! Try to make a more complicated universe, next time.

More than four of either spatial or temporal dimensions?
UNSTABLE! That shit would fall apart.

Unless, do you have two or more of both temporal and spatial dimensions?
That's not only UNPREDICTABLE, that's also ULTRAhyperbolic. The universe wouldn't work, it'd just be way too hyperbolic for anything to get done.

Three temporal dimensions and only one spatial dimension?
That's for tachyons only, motherfucker. Boom doom! Get the fuck out, 'less you a tachyon.

One temporal dimension and three spatial dimensions?
DING DING DING, Goldilocks, you've just described the known universe.
