take for instance the fact that we don't actually know what space, time, matter or energy ARE. we know how the formulas that describe them will hold up in certain contexts, but when removed from that context they contradict each other and give us different 'understandings' of the thing they're dealing with. there's a hope that eventually science will resolve its internal contradictions, but that's really all that keeps it going. it can never tell us what is, only what appears.
