Hyperspace Is a Scary Place: It’s not so much hyperspace in the SFnal sense as the Void Between the Worlds, but the primordial chaos/cacoastrum of the bulk/plenum is, by and large, not a very scary place, because it invariably kills you before you have the opportunity to be scared. Its adjacentia, however, if anyone ever should manage to punch a hole in the universe, would almost certainly be utterly terrifying – the more so the more you understand about them.

(Well, okay, technically it doesn’t, but that’s because there’s no time outside the universe for there to be any instants of. But the effects of cacoastric exposure – to wit,   dissolution/transformation into slightly less primordial chaos, with cake – amount to much the same thing, even if they happen at sausage squared over blue hadron teapot.)
