The Paradox of Artificial Gravity: Einstein Showed Us How to Make It, But Engineering Says It’s Almost Impossible

Artificial gravity is physically possible in theory, but current engineering makes it hard to use on spacecraft.

Long-duration missions and lunar or Martian settlements will need ways to reduce the health harms of microgravity.

Proposed solutions include rotating habitats or dedicated facilities that use centripetal acceleration.

Concepts such as the University of Kyoto’s ‘The Glass’ point to possible future space habitats.
