Also notice how Fuckstar claims he's trying to avoid the "obvious error of scaling off of the glow" as the torp comes out even though this particular kind of error would actually increase the perceived size of the torp, thus bringing it closer to his own exaggerated figure (and thus showing that the real figure is even farther away from his bullshit number).

We're merely establishing a lower limit of the torpedo's yield in this specific instance. I've seen no evidence that the Captain ordered a maximum yield torpedo to destroy this asteroid. After all, if a group of heavily equipped people want to level a building, and their portable rocket launchers(ie: lower yield weaponry) aren't doing the job, it's highly unlikely they'll immediately switch to their portable nuclear warhead launcher.

What I think alot of people are forgetting is that the Federation is dedicated to exploration and peaceful contact. They are so passive in fact, they will pass up an "apparent" option to wipe out their greatest foe, the Borg (ref: STTNG "Hugh"). Mike Wong actually makes an excellent point regarding how stupidly passive this action is.
I agree on all points here. I don't think that those were maximum yield torpedoes, nor do I believe that the Federation exists primarily as a military body. It is more of an exploration party. I have no problems in assuming that other, more powerful examples of torpedo use can be found, but I also see no evidence that the torpedo fired in "Rise" was anything to boast about in terms of firepower. It seemed pretty laughable. More like a kiloton than one hundred fifty megatons.

Their onhand supply of torpedo fuel could be extremely limited for exploration ships, especially if you're cut off from proper resupply facilities, like Voyager.
I have to disagree, here. Voyager was going on a combat mission against the Maquis when it left. If SF was able to modify any ships to make them ready for combat, then they should have upgraded Voyager's weapons and shields, too. While I don't think that the torpedo used in this incidents was the most powerful weapon available to SF, I do think that Voyager was one of their more combat-capable ships. If it were not, it would be an example of stupidity on the part of the Federation command. In one episode it is stated that the number of torpedoes they have is limited (curiously, they fire many more torpedoes than that during the series). If fuel was the limiting factor, then we should have heard them talking about fuel. Their limiting factors were probably the number of torpedoes, and the amount of AntiMatter they could produce.

[sarcasm] But guys, don't you see that you're making Trek more powerful. Now you're saying that an even smaller torpedo can do 100+MT of damage [end sarcasm]

DarkStar this is one of the stupidest things I've ever heard from you. Essentially you're saying that you took a frame with a torpedo a significant distance from Voyager (thus making your scaling subject), and now you defend your scaling as a lower limit? WTF? Even with DasBastard's estimates (measuring seven pixels when I got three), your figures are still exaggerated. Now, when he correct the asteroid size for your erroneous figures we find that the firepower required to force it to crack is laughable. Voyager should have been able to do a hell of a lot more damage than that to an asteroid that size and made of such fragile materials.

Idiot. The torpedo glow increases dramatically after it exits the tube . . . Voyager is only 344 meters long, so we're talking less than 150 meters travelled after it leaves the tube until it leaves the frame including Voyager. Your argument is that I should ignore this brightening, even though it's been seen since "Encounter at Farpoint" as a common quality of torpedoes of the TNG era, and even occurs in the TOS-era movies.

This is just an idle theory but couldnt the tech in the asteriod be a SIF field as well as nav or whatever else it was.

This would explain why they thought the torp would destroy the asteriod (we have no evidence it was hollow) but also why it didmnt break the brittle asteriod it actually was.

This way we keep but pieces of evidence intact instead of setting up what was supposed to happen aganist what did in effect having the torp stated at one level yet demonstrated at another.

I do assume that we agree that Voy's crew should know about their weapons yield.

Thus going off the crew estimation we get a yield and then explain why that yeild isnt shown (SIF field, Gamma radiation (do trek torps release gamma radiation and not one of those trek radiations which we dont nkow the properties of), DS brittle materials etc).

Anyway just a guess

Interpreting the events is quite simple:

1) the crew of Voyager did not expect the torpedo to completely vapourize the asteroid (and it didn't)

2) based on proper scaling and tons of canon evidence for the true size of photorps (i.e. ~2 m on its longst axis),we know that the asteroid measures at most 75m on its longest axis by ~ 40m - giving a total volume on the order of 100,000 m^3.

3) the energy required to vape 100,000 m^3 of nickel-iron is ~1.5MT

Therefore, even accounting for 50% losses to omnidirectional energy release, the torpedo fired could not possibly have yielded more than 3 megatons.

Given that the fragmentation energy for a rock of that size is ~1kT, we can state with that the events of 'Rise' indicate that the yield of the torpedo is between 1kT and 3MT.

It also doesn't make sense to argue too heavily for this instance, I believe it is commonly accepted that photon torpedoes have variable yields. So Voyager simple fired a torpedo they felt was the right yield to destroy the asteroid with minimum fuel for the torpedo(hence theri confusion). They are stranded, so they're not going to use fuel like there's no tomorrow.
I have to disagree, here. Voyager was going on a combat mission against the Maquis when it left.
Point taken. I'm suprised I actually didn't mention this myself, since it's a good reason why Voyager would have a fancy weapon like a "tri-cobalt" device they used to destroy the CareTaker array.
If SF was able to modify any ships to make them ready for combat, then they should have upgraded Voyager's weapons and shields, too.
Well, perhaps upgraded is not the word I'd chose, but for sure that all their weaponry is setup for combat mode and shields are at peak efficency, etc.

If we were to conclude that Voyager was upgraded to a small warship status, that might change some of my perceptions regarding it's actions and defenive capabilities in the Voyager series. Though it was still subject to proper resupply problems, etc.
While I don't think that the torpedo used in this incidents was the most powerful weapon available to SF, I do think that Voyager was one of their more combat-capable ships.
Undoubtably, hence one of the reasons they didn't do too bad against the Borg. I actually find it quite amusing that Voyager, orginally equipped as a combat vessel, and with it's shield strength multiplied by a factor of ten(STVOY "The Q and the Grey") still got swatted easily by the first cube it truely encountered (STVOY "Scorpion", a cube locks on a tractor beam, completely disabling Voyager's shields, and beams Janeway off the bridge).
If it were not, it would be an example of stupidity on the part of the Federation command.
However, I don't think it would either the first of last example of it...:)
In one episode it is stated that the number of torpedoes they have is limited (curiously, they fire many more torpedoes than that during the series).
I would guess that if Voyager was equipped as a combat role vessel, it's equipment could included small facilities to build more torpedoes on hand.
If fuel was the limiting factor, then we should have heard them talking about fuel. Their limiting factors were probably the number of torpedoes, and the amount of AntiMatter they could produce.
Actually, the anti-matter was the "fuel" I was referring to, my mistake for bad clarification.

If it qwas setup in "combat mode" as you call it then why did it have less than a fifth of the torps the Ent-D carries around which wasnt setup for anything for than being a cruise ship.

They were only going after the Maquis remember not exactly a big threat (and one particular maquis vessel at that).

Because the E-D is much much bigger? Maybe because Voyager has a crew of 143, while the E-D has over a thousand? Size obviously. I think scaling would show the E-D as quite a big factor larger than Voyager.

Perhaps it's near the Cardassian border, and the Maquis isn't composed of just one ship? What if the Maquis went and got reinforcements? What if they encountered hostile Cardassian forces?

I should note the Intrepid class is a fraction of the size of a Galaxy class. It's combat load would therefore be lower.

40 or so Phton torps isnt enough for extended combat - it obviously wasnt going on an extended mission - the Maquis werent considered a threat at the point Voyager left on its mission (witness the shock duting For the Uniform (season 5 DS9 Voyager Season 3) that the they actually took on and defeated a Federation Starship.

Theres no evidence that Voyager was in combat loadout (the Ent-D doesnt have a crew of 1000 by the way alot of those are family members etc).

40 Photon torps may be ok for standard non extended missions for Voyager but I wuold imagine a combat loadout would be far higher.

The Cadassians werent deploying ships against the Maquis remember (not into the DMZ but they were into the badlands - also remember it was a search and rescue mission (the cardies said the ship was destroyed but SF thought it was in the badlands somewhere)) and the Federation had a peace treaty with them - there was no reason for a combat loadout.

Hmmm.... I can definitely see what Darkling is saying. 40 torpedoes is too low for an extended combat mission. It would more adequately serve in an exploration role. On the other hand, Voyager should have gotten more torpedoes anyway. The Enterprise D was an explorer, and it had a thousand torpedoes according to most accounts. I can also, of course, see that Voyager is smaller and less powerful than the Enterprise D, and so it could just be a difference in classes. I don't really know. I would have thought, though, that any ships on the border of Federation territory would have been outfitted at least partially for combat, at least on a small scale.

Torpedoes are variable yield.

Actually, no. As I make reference to on the site, I have used something lower than the median value for the asteroid's width . . . it's depth is similar. Therefore, I have arrived at a figure which should approximate the true value, even including the slight rounding at the bottom, and more substantial rounding at the top.
No you haven't because you have no evidence to demonstrate what the depth is. the object, to all appearences is viewed in the same plane every single time. You cannot accurately measure all three dimensiosn without views from some other plane to give us a clue as to depth. You are baselessly assumign that depth and width are equal without showing why. Now if you CAN show why you made this assumption then feel free to tell me why because otherwise you just pulled a number out of your ass and stuck it in there, for all the proof you've shown the depth of that asteroid could be 10m.


Note: I do not even think the real number is close to that but I'd like to see where you get off syaing that width is approximately equal to depth without explaining how you arrived at this conclusion.

I think that every third party has been convinced of my victory on this thread. If you are a third party who does not think so, PM me and Darth Wong, and E-Mail DarkStar telling us that you don't believe he's wrong on this issue. If you have your own theory, you need only PM me, or post.

It is September 12, today. If, on Friday the 20th, no one has posted anything else of significance here (I'll post here in response to any PM's I get during that time), can I get a mod to close this? It's really not very sporting to attack DumbShit's site without giving him a chance to evade/ignore arguments against it.

This quote is from memory (so the number might be wrong, but it's not too far off) but when confronted by the need to do combat - I think this is an ep when they find a living nebula, it was like a 2nd or 3rd episode of the series:

SOMEBODY: We have a standard compliment of (12-24?) torpedoes.
JANEWAY: Which we can't replace.

Obviously Janeway was stating that they would need Starfleet facilities to replace them, she didn't mean that they couldn't replace them RIGHT NOW during the combat... there was no mention of an amount of antimatter in grams or kg.

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:
http://mineral.galleries.com/minerals/p ... acture.htm
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.

Master,

I still have a hard time accepting that the entire rock could be
easily shattered with a pick-axe. As I mentioned earlier, since that asteroids' fragments were considered a danger to the people below,
they'd have to, and did, survive atmospheric entry. Just off-the-cuff
(no numbers to support this assertion), I'd have to say that indicates
the rocks are fairly tough. Then again, I don't remember the size
of the fragments as they entered the atmosphere.

Also, though I agree the scaling needs a closer look, I don't think
one should dismiss the idea that a nickel-iron asteroid of that size
was expected to be largely vaporized. That is, at least,
the only explanation I can come up with to explain why "we shouldn't
be seeing debris greater than a centimeter in diameter," though
I could be wrong. I'll always take empirical evidence over someone's
word, but the asteroid was at least in part an artificial construct.
To completely dismiss those expectations would be short-sighted, IMO.
(I'm not saying you're doing that, though :) .)

Rocks don't really have to be tough in order to survive re-entry. There really is not enough atmosphere to vaporize any asteroids larger than a few meters across on Earth (assuming a favorable entry-vector, which is reasonable due to the asteroid's guidance system), but since asteroids larger than that in Earth-crossing orbits are so rare, and since so many asteroids instead hit the moon or Jupiter, or skip off the atmosphere, it would also be reasonable to assume that the asteroids were not be nearly as large or strong as DarkStar needs to prove his case based on this particular incident.

I think it would still be a danger though becuase it's vapourized material would stilll fall to the planet, get stuck in the atmosphere, and cause a nuclear winter.

If I'm wrong on that please correct me.
