It’s the holy grail of space travel: artificial gravity, so we don’t all float around and have our muscles atrophy while we’re exploring the stars. Well, it’s actually attainable right now — just insanely, astronomically expensive.

Real Engineering decided to tackle the issue with a new video clip, breaking down what it would take to create a space station with artificial gravity. The pitch focuses on the only viable concept we have right now for artificial gravity, centrifugal force, made famous in films like 2001: A Space Odyssey and Elysium.

It’d just cost about five trillion dollars to build a viable station, and take 10 years' worth of the Earth’s aluminum availability to create. So yeah, we have a long way to go until we’re kicking around in artificial gravity, but it’s nice to know the tech is (conceivably) sound. Admittedly, it's not as easy as Star Trek makes it look, but it's a start.
