How It Works

Could transport through wormholes be possible?


While wormholes are theoretically feasible according to the laws of physics, there’s no evidence that they exist. Tubes that provide shortcuts between different parts of the universe are a nice idea, but the concept presents a number of problems in practice. Even if they did exist they’d probably be very tiny, threadlike connections so in order to pass through you’d find yourself stretched out, or ‘spaghettified’, into a narrow stream of atoms. Keeping a wormhole open for practical travel would need some kind of antigravity force – and while that’s also a theoretical possibility, it might be easier to find another form of high-speed travel, or indeed just to take the scenic route.
