Kinda like the guild navigators in Dune?

Well yeah I forgot about wormholes/black holes kek. I should've been more clear I was talking about just light speed travel as is. But you're absolutely right. You just bend space time around yourself. I can't remember where I saw it, but you draw two dots on opposite sides of a piece of paper, one line between each is the most efficient path. But if you fold the paper up to make the dots touch, that's basically what you do by manipulating space with like a wormhole or whatever.
