HOLY FUCKING SHIT! DarkStar decided to defend himself on his website against my attack! I will send my response to him via e-mail, so he has a chance to respond by either messaging me back, or by putting it on his website (so everything is more sporting).
Objections
1. If Chakotay was able to tap a piece of the asteroid open with a little pick-axe, the asteroid must have been brittle. If it was made of such brittle materials, Voyager's torpedo should have done more damage.
There's a profound difference between taking a sharp pick against a solid rock and vaporizing it with a photon torpedo explosion. First, a rock has characteristics such as cleavage and fracture. That is, in fact, one of the ways rocks are identified.
Torres identifies olivine as one of the substances in the rock. You'll note that olivine has a brittle, conchoidal (shell-like) fracture. In other words, it breaks easily into curved fragments, not unlike glass does. Also pay attention to the fact that it is rather hard, but with a low density. Something hard, low density, and brittle is going to be easy to crack
Compare this with iron, which they thought the asteroid was made of. It's softer, and thus more malleable. It has a higher density, and a jagged, torn fracture. Now, let's say you fire a bullet at a wall made of olivine. You'll probably end up with a hunk of broken fragments flying away, and might even get cracks running from the point of impact. Do the same to an iron wall, and if the bullet penetrates more than a dent's worth, you'll get torn metal.
There is a difference, however your statements are still incorrect. The energy requirements to fracture something are almost always VASTLY lower than the energy required to vaporize it, and they can never be higher. The reason is really common sense. When you fracture something, you are evidently only breaking the molecular/atomic bonds (depending on the material) along one plane or rough plane of the object. When you vaporize something, you are breaking ALL the atomic or molecular bonds within that object. Of course it takes more energy to vaporize something than it does to fracture it, and the energy requirements to fracture even pure olivine are much lower than the requirements to vaporize pure iron.
Detonate a thermonuclear weapon next to that wall, and the olivine wall will probably shatter. The more resilient iron wall may either tear wide open, or just sit there and melt, et cetera, depending on various factors.
The point is that if your claims were true, and they were attempting to vaporize that asteroid, then the energy requirements to fracture it would have been so much lower than the energy requirements to vaporize the asteroid as to make any comparison silly. Your analogy is totally irrelevent.
This would assume, of course, that the entire asteroid was olivine, and not nickel-iron with a couple of oddball chunks of olivine. Given the fact that it fragmented in the way it did without vaporizing as expected, that isn't a bad hypothesis. But, then, the Nisu astrophysicist dude mentioned in his transmission that the asteroids were composed of artificial materials . . . whether he had simply found evidence that triatium alloy was part of the asteroid, or had found that sensor signals were being distorted, or found that the majority of the asteroids were literally artificial is not clear.
But in the asteroid that we see fractured, we do not see results typical for olivine. We see NO evidence of a conchoidal fracture. Instead, we see all the patterns of an uneven fracture. You can see a VERY brief summary of the difference at:

The asteroid fragment Chakotay cracks open is clearly not made of substantial amounts of olivine. Its properties were clearly not those of olivine. Your rebuttal is irrelevent. So here's the question, are you claiming that the asteroid fragment was made primarily of olivine or artificial materials? Your assumption about how brittle the material was is flawed, because we can easily see that the asteroid did not demonstrate the properties of olivine.
In any event, the brittleness of a material is no indication that it will be easier to vaporize . . . indeed, it is far more likely to fracture uncontrollably, and in this case unexpectedly.
You are correct insofar as that the brittleness of the material is no indication of how difficult it will be to vaporize, however this does not explain that lack of fracturing we see in the asteroid that Voyager fired upon. Had the weapon had anywhere near the yield that you are claiming, the asteroid would have fractured far more completely. I stated this, earlier. Try to pay attention.
In the video clip, we see very little uncontrolled fracturing of the asteroid. We also see almost no unexpected fracturing of the asteroid. We see no conchoidal fracturing of the asteroid. Try to pay attention.
2. Voyager didn't actually destroy the asteroid, therefore you can't claim firepower off of this episode.
Why not? The crew fully believed that they had an iron-nickel asteroid before them, and that it could be vaporized by photon torpedo. The fact that it wasn't vaporized does not negate their belief that they could have done so. Further, a 100m chunk and a smaller, perhaps 50 meter chunk flew toward the planet. Another chunk of about 40 meters flew off to the left. There was also a bunch of other crap flying around, but it's too small (and the vidcap is too low-res) for me to get much more out of it. Let's say, for the sake of argument, that an extra 50m asteroid's worth of material made it out of the torpedo blast.
If all that is correct, then it means 688,410 m3 of debris was left over by the torpedo blast. For an asteroid that started out at 13,500,000 m3, that ain't half bad.
DarkStar, DasBastard demonstrated clearly that your scaling was incorrect. You grossly inflate the size of the asteroid being fired upon. This also, by extension, means that your scaling of the fragments is incorrect, and your scaling of the amount of truly vaporized material is also highly suspect. Please revise.
Now, your premise is correct, however your analysis of the incident is fairly inaccurate, from what I can see.
