To me, jump holes are utter, pardon the word phrase; utter bollocks.
How can a tiny hole handle a massive tube shaped ship? No innuendo intended, but it is something that has really bugged me.
Now, let us replace most if not all jump holes with 'navigation beacons' which stores the necessary data in order for a ship to jump to the next system. Main reason why they wouldn't be stored on the ship? The amount of calculations needed to successfully jump with great precision takes time and large amount of processing power. Therefore, an organization placed beacons near jump holes in order to maintain safer travel without relying on unstable jump holes.
In 'lore' they're arguably unstable, though that is only from Ageira was it?
So, replace jump holes with navigation beacons, thoughts?
