Well, at such extremes as the fundement of reality things get a little silly. The reasons it gets a little unclear are...well probably unfathomable in number and scope, but the following will possibly give a little sense of some of them. Currently, its uncertain what the absolute most basic building blocks and units of existance are and whether all of them actually are entirely consistant. Moreover, currently there is reason to believe that information itself is actually somehow a more basic building block than the simplest units of space, energy, and matter and also actually less capable of being created or destroyed in its most basal form. Great, so what's the issue? Well, this actually means its hard to sort out if these most fundemental pieces are fundementally and primarily math first and physics second or vice vs. The "mathiness" of this info may only be an emergent thing. Basic logic works kinda weird all the way down there. Or is it up...there? Point is its a weird time in math and physics and basically the line between the two is getting very blurry.
