The reference points are divided into reference frames (space) and reference values (time). Reference frames are subdivided into inertial (if the observer is at rest or moves with constant velocity) and non-inertial (if the observer moves with variable speed or acceleration).
Reference values can be:
- Standard: those we see commonly in clocks.
- Relative: those obtained at high speeds including c.
- Regressive: travels to the past.
- Progressive: travels to the future.
Although I believe that time travels aren't feasible, I've included them because some think so.
