Technically, those are physics holes. Metaphysics is something else entirely.

And the first one might actually qualify as a genuine plot hole, given the importance of the Conduit (unless there was an explanation for this somewhere). It does seem like sometimes the writers forgot that mass relays aren't the same thing as your standard ftl-gate.
