FTL

FTL, an abbreviation of faster-than-light, is a method of travelling faster than the normal speed of light which does not involve the use of mass relays. Once a vessel makes a jump via a mass relay, conventional FTL can be used to move around the space surrounding it at reasonable speed.

Physics
FTL drives work by exposing element zero to electric currents, creating mass effect fields to alter the space of a spaceccraft. It reduces the mass of an object to a point where accelerations faster than the speed of light are possible.

The precise maximum speed and the time it can be maintained varies depending on the exact type of FTL drive being used.
