Hyperspace for dummies

[Malenfant]

The only way that the jump bubble concept makes any kind of sense to me is if the jump grid on the ship's hull is pumping out hydrogen continually for the week that the ship is in jump to make the "bubble" (actually a very thin hydrogen atmosphere around the ship that needs to be continuously replenished because jumpspace is destroying the hydrogen).

Of course that also means that if the hull is damaged, then so too is the jump grid, and that means the ship shouldn't be able to jump without being destroyed in jumpspace because there will be patches on the hull that aren't covered by the jump grid.
