I take the figures for the Imperial Star Destroyer from StarDestroyer.net, which I think is being unreasonably kind to them, as the author uses the methodology of accepting only lore that points towards a higher power level, and ignores evidence for under powered Star Wars weapons. For example, in the battle over Coruscant in Revenge of the Sith, taking a turbolaser hit in a gun bay produces a relatively mild explosion, and leaves several clone troopers alive. Similarly, in Return of the Jedi, an A-Wing hitting the Executor at a relatively slow speed (certainly nothing like relativistic) does far more damage than a turbolaser bolt. Or when, in The Phantom Menace, Anakin uses a fighter to kill droids in the hanger, they are merely dismember, not vaporized as one would expect from the calculations at SSDnet.
Nonetheless, taking them, a Star Destroyer with 60 turbolaser batteries will put out around 1900 megatons every second. That's pretty impressive. Of course, my Hawk frigate, fit with light missiles, puts out around 880,000 megatons every second. Of course, a Hawk frigate is something around the size of a C-141 Starlifter (
http://en.wikipedia.org/wiki/Lockheed_C-141_Starlifter), but still. Or, in other words, a Star Destroyer, if I have my math right, does around .5 dps.
If you want something like a Star Destroyer in the EvE universe, though, to be fair, you need to compare it to something like a Raven battleship. Let's say that the Empire attacks the State. A Raven Navy Issue, with CN Ballistic Control Systems, CN ammo, and CN launchers, but no drones, does 1,100 DPS with level V skills. Lesser skills will take it down a bit, but not much. It has a volley damage of 7,868. Or, to put it another way, a Caldari Navy Raven will output 4,400,000 megatons per second, with each volley delivering 31,472,000 megatons. The .5 DPS per second of the Star Destroyer will probably not overcome natural shield regeneration under any circumstance.
With this sort of disparity, the alleged vast numbers of the Empire are entirely moot. In fact, if an EvE dreadnought managed to get into the SW-verse, it would be a super-weapon.
Sorry, my post got cut off somehow. Anyway, what I was going to say is that a war between any of the major EvE entities and the entire Star Wars universe would end very quickly, and very badly for the Star Wars side. That's even if the EvE entity is one of the pirate factions. If it was, say, the State, which is, as of EvE:Source, the strongest non-Jovian entity in the cluster in military terms...well, you get the idea. Even EvE travel is faster and more efficient than Star Wars travel, if somewhat less flexible. Still, the empires have jump drives that don't need cynos.
