Very good. They only call c the speed of light, but I guess light can't move at c. Ok, anyhow, I've just figured a weapon that could easily decimate the Death Star in one shot, thus one siding the battle. Don't worry though, you still have your fighters that possess the firepower of a small Federation fleet... without quantum torpedoes.
Quantum torpedoes use a subtle, little known energy known by many names. "Quintessence", "Zero-point energy" or "ZPE", and lastly, the common name is simply vacuum energy. It exists where nothing else does, in a non-particulate form. It is instead of attracted to, repelled by gravity (justifying why is exists in vacuums). It houses 2/3 of the universe's energy, and has been nearly proven with instances of the Casmir Effect. It is such a dense energy, that if its negating counterpart were not present, the universe would expand so fast that all particle electrostatic and nuclear bonds would be broken. Now, Quantum torpedoes can't trigger a universal release of this energy, but they can trigger a local release of the energy (by negating the counterpart force). It doesn't matter how strong you boast your shields to be. It doesn't matter what armor you have. And starfighters, as said earlier, are little more than cannon fodder. If that controlling energy is released locally, even for a billionth of a second, the damage would be catastrophic. Even to the Enterprise. But, nevertheless the Federation has utilized them, on Starfleet vessels.
If you don't believe me, look at this. The Star Trek Encyclopedia simply states that quantum torpedoes trigger a localized release. Now, the Encyclopedia has been used ONLY to identify the principle behind the Quantum Torpedoes.
PhysicsWeb.org -- "Today's cosmologists find Lambda to be just as objectionable, but for a different reason. All quantum fields possess a finite amount of "zero-point" vacuum energy as a result of the uncertainty principle. A naive estimate of the zero-point energy predicts a vacuum energy density that is 120 orders of magnitude greater than the energy density of all the other matter in the universe. If the vacuum energy density really is so enormous, it would cause an exponentially rapid expansion of the universe that would rip apart all the electrostatic and nuclear bonds that hold atoms and molecules together. There would be no galaxies, stars or energy as we know it."
www.grc.nasa.gov/WWW/PAO/html/warp/possible.htm#vac -- "In simplistic terms it has been said that there is enough energy in the volume the size of a coffee cup to boil away Earth’s oceans." (Popular Science, May 2001, mentioned the 1 cc of space could tackle the whole boil the oceans thing)
There ya go.
Beware the "L" hat...
