c
Speed of Light ( ~= 3 * 10^8 m/s )
FQSD
Forced Quantum Singularity Drive. A miniature black hole used
on Romulan Warbirds as a power source for their warp drives and
other shipboard systems.
FTL
Faster Than Light (usually communication or travel)
IPS
Impulse Power System. The Newtonian STL drive used on board
Federation starships.
M/AMR
Matter/Antimatter Reactor (also called the warp core). Power
source used on Federation and Klingon starships. Romulans use a
FQSD.
Newtonian
Term referring to action-reaction systems. For example,
propulsion by means of pushing accelerated gas out the back of
a ship, where the reaction causes the ship to move forward. The
IPS is an example of this. Warp drive has no normal
action/reaction component associated with it, and is called
non-Newtonian.
STL
Slower Than Light (as opposed to FTL).
tetryon
Subspace particle unstable in normal space. Appears to be the
primary particle associated with subspace fields and subspace
interactions.
verteron
Particle associated with subspace interactions. Appears to
inhibit the formation of subspace fields, damaging or rendering
devices which use subspace useless.
warp
One method of FTL travel used in Star Trek, in which nested
subspace fields create a propulsive effect.
Warp
"Unit" for warp factor, as opposed to the technology.
warp coil
One of many units in a warp drive; shaped like squashed
horseshoes, and paired together to form rings, plasma is pumped
into them and the exotic materials forming them create the warp
effect.
warp core
See M/AMR.
