On reflection, I think what gets me about the science is that it wasn't technobabbly enough. "Red matter" sounds like they weren't even trying, and supernovas and black holes, being real things we know about, were distracting because they don't behave that way. If the black holes had been, I dunno, subspace gravitational anomalies or something, then I could write them off more easily.

If that makes any sense at all.
