[Star Trek/Star Wars] What are the differences between Subspace and Hyperspace?
gpt
Subspace consists of many different layers that are still vaguely connected to normal space. Subspace is also the only place where tetryon particles naturally occur.

Hyperspace is a different dimension that can only be traveled on certain routes, due to the danger of mass shadows.
