Star Trek Stays Local: The Milky Way, Barriers, and Budget Constraints
The article argues Star Trek mainly stays inside the Milky Way because a fictional galactic barrier at the galaxy’s edge, plus warp-drive limits and narrative economies, make intergalactic travel impractical and expensive to portray. Keeping to one galaxy provides clearer storytelling, humanoid aliens, and production feasibility, with rare out-of-galaxy forays like TNG’s M33 moment explained as exceptions. It also notes real-world distances to nearby galaxies (Canis Major Dwarf, Sag DEG, LMC/SMC, Andromeda) and uses warp-speed math to show how long intergalactic journeys would take, reinforcing that the show’s choice is as much about narrative clarity and budget as it is about in-universe physics.
