** Warp factor ** (abbreviated wf) is a unitary quantity that expresses the speed of a starship, or a signal using warp speed, that is, a speed that is greater than the speed of light. The warp factor is a non-linear measure of speed. Warp factors are relative to their superluminal equivalents and depend on the local characteristics of space and subspace, so the data are only approximate. Warp velocity values ??are derived from ambient conditions (gas density, gravity, electric and magnetic fields, and fluctuations in subspace).

** Light year ** is a unit of distance defined by the IAU as the path that light travels in a vacuum in 1 Julian year. Corresponds to a length of 9,460,730,472,580,800 m. This value is accurate because the meter is actually defined in terms of the speed of light.

** Parsek ** (abbreviated pc) is a unit of length used in astronomy. It means the parallax of one angular second.

It is based on the trigonometric parallax method, the oldest and most common method of measuring the distances of stars. The angle opposite to that of a star star with the mean radius of the Earths orbit around the Sun is called parallax. Parsec is defined as the distance from Earth to a star that has a paralysis of 1 second (arcsecond). Otherwise, a parsec is the distance from which two objects, spaced 1 astronomical unit apart, appear to be separated by an angle of 1 second.
