Mass lightening is a technology used by many races in Star Trek. The effect of this technology is to reduce the effective mass and inertia of a large object like a starship so it can be accelerated quickly with a relatively small amount of thrust.
How it Works
Mass lightening technology is fictional, and its fictional principles have never been clearly explained in any Star Trek series or movie.
The technology is known to involve subspace field effects, so a common hypothesis is that the technology somehow shifts the ship's mass from normal space to subspace, where it has no inertia. A rather small amount of thrust is sufficient to rapidly accelerate the mass that remains in normal space.
A consequence of using mass lightening technology is that Star Trek ships are highly susceptible to subspace phenomena, like the subspace shockwave from the Praxis explosion[1].
Mass Reduction
How much the mass lightening system normally reduces the starship's mass isn't known, but the subspace fields have been used to reduce the mass of other objects on at least two occasions.
- In TNG "Deja Q", the Enterprise-D used its warp nacelles to generate a subspace field that reduced the mass of a moon from an estimated 6.5E13 kg to just 2.5E9 kg, reducing its mass by a factor of about 26,000.[2]
- In DS9 "Emissary", the station generated a subspace field from its deflector shield emitters that reduced its mass enough that it could complete a 160 million km trip that would normally take approximately two months in less than a day. This would require reducing the station's mass by a factor of at least 4,000.
