Well, not in a way that you don't already accept for general relativity and quantum mechanics, and not for any metaphysical reasons. But did you know that GR predicts we can build a sub light star drive that shields passengers from acceleration, just by using laser beams to hold together a Jupiter sized shell of matter. The matter shell could be accelerated at 100 Gs by massive star scaled lasers. But so long as it respects certain warp equations and energy conditions, the passengers would feel no acceleration. That's possible with just physical matter, but GR also predicts negative energy. That allows us to theoretically build things like portals to far away portions of space, just by spinning a ring of matter and zapping it with negative energy. The weird possibilities only seem to multiply if you add quantum states to the mix, and the potential for a larger quantum universe. Think of that a giving us many extra toe holds into the kind of spacetime fuckery that GM enables. Plus new kinds, like the idea that different realities or nonlocal regions of space could share quantum variables and allow universal travel and communication that way. Which is just amazing , and also terrifying because of the possibility of encountering very strange and dangerous places! The strange part is not that there is some outer spacetime view where things are static and crystalline. It's that the bulk crystalline structure seems weirdly malleable and reconfigurable by subjective agents, and likely inhabited by other minds that live in portions of that crystal that are alien, and maybe even fundamentally dangerous to us. That makes these hyper determinist models a real mind trip! Okay, the structure is determined. But why is it determined in such a way that it causes such weird and disruptive potential experiences for subjective beings? And how would we cope if the structure let us build hyper technologies to, eg, contact aliens, travel to other universes, or change the laws of space and time?
