Red Nemesis
The Blind Critic
Nai, I'm going to have to disagree with the direction you've taken with your analysis.
As Faunus noted, the strength of the various Dovin Basals' singularities varies greatly. In fact, if they did not then the basals themselves would be largely unusable as transportation mechanisms. The force of gravity varies with the inverse of the square of the distance, meaning that each singularity would have to be placed with much, much more accuracy than they appear to be. The basals would also have to have a much longer "casting range" under this system.
Nai takes two things as given:
a)
The dovin basal "black holes" have been shown to "absorb" enemy weapon fire. And it has been explained, that this happens via a gravitational field similar to a black hole.b)
Luke did manage to manipulate the force to counter and even overpower that gravitational pull.
The second is dubious, even if we allow for the fact that it is a vaguely remembered detail from a poorly written book. Gideon pulled the Wookiee's description, so we'll use that:
"During the Battle of Dantooine of the Yuuzhan Vong War, Luke tricked a vehicle's dovin basals into colliding its own black hole against itself by using the Force to hold the void against the pull of the dovin basals; then reversing the direction of his own pull, adding it to the pull of the dovin basals, so that the void would collide against the spine of the vehicle" (per Wookieepedia)
This indicates that Luke wasn't overcoming the (yet undefined) mass of a black hole alone. Rather, Luke was overcoming the manipulation of a Dovin Basal
on a black hole. The difference here is staggering. Luke would, in the first case, have to overcome the inertia of a (presumably) very massive object. That assumption is, I believe, behind the awe given to this particular feat. However, the actual mechanism may have been very different. I am aware that this isn't the source material, but I have no reason to believe it is inaccurate.
The description given indicates that Luke simply canceled out (or even just muted) the controlling basal had over the black hole in question. Unless you want to argue that each ship-sized Basal is capable of putting out energy on the scale of a star it is incredibly likely that some specialized mechanism is behind the manipulation of singularities for maneuvering. This force is all that Luke would have to match. This scenario allows us to avoid a Stellar-Luke (which is not likely in given his other showings) and remain in canon. Luke would only have to match the applied force enough to get the Basal to overcompensate. Then his job is done for him, and down it goes.
In this way it becomes clear that Luke does not necessarily exceed the Sun in energy output (which is an idea I simply refuse to consider). This conclusion is upheld when we consider the variation between the singularities we've seen generated. Some Dovin Basal black holes are capable of absorbing various blaster shots, while other propel Vong ships through space. The two systems operate largely independently of each other, as seen by CoralSkippers maneuvering and using this active defense simultaneously. If the 'shields' cast a gravitational field strong enough to affect the course of a ship then locomotion would quickly become impossible, as ships get pulled towards blasts that they are being shielded from.
(Credit to Faunus for a much more concise version of this argument that I hadn't realized was there until after I'd already typed it up.)
From all this we can see that Luke's divinity is far from established. But what about the feat itself?
Nai, you say that the black holes would evaporate almost instantly. Isn't that what we see in the books? The Basals create the singularity, use it for whatever they need, and then move on. When their attention is divided (or their will broken) does the singularity remain? I can't remember, but I don't believe so. Moreover, the regions of space where battles take place are not left riddled with black holes. It seems entirely likely that the black holes are not self-sustaining (or, at least, radiate themselves away extremely quickly). After the missile/blast is absorbed, the black hole does disappear. This lends credence to the idea that the singularities are actually smaller than the [lower limit of size].
On top of this we have the fantasy elements of the black holes. When they are activated as a method of propulsion, the effects are limited to a single coralskipper. In Star Wars dogfights the fighters tend to become mixed up in a sort of scrum. Would a propulsion system that interferes with the trajectory of your allies be carried into battle? It seems unlikely. Also, I would be hard pressed to find an example of an Alliance ship being pulled by the singularity. A black hole (without any fantasy overlay) would pull all ships around it, not just the one that generated it.
It seems likely that the actual system includes some sort of directionality; when moving, all of the gravitons are pointed in a certain direction, so the effects of a smaller mass are multiplied and can be controlled. Under this system the mass of the black hole that Luke moved might be much smaller indeed-- one third or less (depending on the spread of gravitational pull) of any equivalent body. So from your 3.8E28 J we can deduct two thirds, and then lower that even more if the dovin basals only use as much pull as is necessary for the situation.
I'm not convinced the feat means much at all right now.
