"[Science fiction] is the one literary medium left in which we have a free hand. We can do any damn thing we please."
- Alfred Bester

| Pseudogravity | ||
| Gravity produced by artifice, rather than by a suitably large mass. |
This term was typically used to describe the "gravity" created in a spinning orbital habitat; later, it was extended to other types of artificial gravity.
| Bobo trotted away in the long loping strides permitted by the low pseudogravity near the axis of rotation of the Ship. |
| From Common Sense,

Heinlein uses this idea again in his description of Wheelchair, the orbital home of Waldo F. Jones in the 1942 novella Waldo:
Waldo F. Jones seemed to be floating in thin air at the center of a spherical room. The appearance was caused by the fact that he was indeed floating in air. His house lay in a free orbit, with a period of just over twenty-four hours. No spin had been impressed on his home; the pseudo gravity of centrifugal force was the thing he wanted least. He had left Earth to get away from its gravitational field; he had not been down to the surface once in the seventeen years since his house was built and towed into her orbit; he never intended to do so for any purpose whatsoever.
