It's not like we don't want to help, but you are not asking for help, you are asking for ANSWERS, and we cannot know what is in your head, we just can't.
Chaka said magnets, but in a broader sense, that's gravity. Perhaps your scientist can be working on the effects of creating artificial gravity wells and it's effects on hyperspace lanes and finds that by using interdictors, it alters the lanes themselves?
What if one gravity well reduces speed, but he discovers by applying four or five, it actually increases speed by narrowing the hyperspace lane?
It's relatively boring, but potentially a game changer.
What you call that, that MUST be up to you.
