A fictional jump drive and its navigation constraints

How does the requested Merchant setting handle space travel?

The participants tentatively identify a jump or hyperspace system, with a bubble around the ship and massive objects disturbing the transit space.

The setting's name is unclear in the spoken question, and the participants qualify their answer by saying they may have found the intended one. Their description involves traveling to a jump point, entering a parallel space, and emerging elsewhere. An Einstein-Rosen bridge is offered as a comparison. A bubble around the ship assists passage, while stars and other sufficiently massive objects disturb hyperspace. The available description supports those broad rules without establishing more detailed performance.
