Starfield is going full Star Trek to travel to the stars, letting you "fold space" to reach distant planets and systems. For anyone not up on their impossible transport technobabble, that's basically the warp drive from Star Trek and just about every faster than light fiction - warping or folding space to put you in a new location.
The recent Starfield Direct has finally clarified it's in-game transport system, explaining how the previously revealed Grav Drive will let you travel between all the Starfield star systems in the universe. The idea behind folding space in Starfield, which is basically how Star Trek's warp drive works, is that you don't technically move - instead space is deformed around you put you in a new position.
