[Lord Azagthoth]

Your scientist might discover lignan ore and has some reports that in the past, an accident with lignan ore transported a ship 5,000 years to the future. Or he has the reports and went searching for the ore.

He is no Force user so he puts his scientific knowledge at work but he'll need the support of a Force Sensitive guinee pig (sapient, sentient or even a plant). Maybe he tries to use the ore to make a time jump backwards (which of course doesn't work because its impossible).

Research for communicators that will work while in hyperspace (in the old movies this wasn't possible, in the Disney canon it is and maybe your scientist is the one respobnsible for it). But when he succeeds, your ship might be the only one having it (if you also have an engineer who can build it) for a while.
