Universe 0019-"Hypothetical"

This is purely for my own weird sort of enjoyment. If you find anything that seems similar or taken from an IP assume that it is. Actually, DM me or something about them; might actually not have seen or heard about it and I would maybe actually like the original stuff behind it. I try to keep up with relevant science and keep things as realistic and consistent in-universe as I can, so if you spot any weird inconsistencies with either the fictional physical laws or the IRL scientific laws and theories, please DM me on that. End result may get at least a little strange, with tech levels maybe going everywhere on the spectrum with "magic" or whatever I decide to call it sitting along with similarly weird future-tech and stuff. Expect a lot of spacetime control in the higher tiers, maybe delving into the weirder, more esoteric theoretical physics hypotheses, or at least as much as I can understand of them.
