Oh goody, I just feel like smacking this fool who dares question my calcs with such stupidity.
Some foolish Disciple of Darkstar wrote:Do you realize how inherently self-contradictory your position is? You admit that lowering the pressure level lowers the temperature needed to boil, yet claim the same amount of energy is needed? How is that possible? Less heat = less energy. Even preschoolers are able to handle such a concept.
The temperature at which an object boils is not the ONLY factor in the energy required to vaporize an object. Here is the key concept you seem to be missing: HEAT AND TEMPERATURE ARE DIFFERENT. Temperature merely indicates the direction in which heat will flow (i.e. heat is always flows from higher temperature objects to lower temperature ones until they reach thermal equilibrium). Heat itself is a measure of thermal energy.
Now back to your ignorance of why these high energies are required. In order to vaporize a molecule must pay the latenet heat of evaporation. Temeprature and pressure variables merely determine WHEN (not how much) a molecule pays this price. The calcs available both at Mike's site and my own do not pay attention to the energy neccessarry to raise the object to the boiling point in 1atm. Rather they merely pay the latent heat of fusion and the latent heat of evaporation (note again to become liquid the object must pay a price as well).
Some foolish Disciple of Darkstar wrote:If your engineer friend told you such a contradictory thing, he is either lying about being an engineer, or simply lying about the facts.
At vacuum, water boils at it?s melting point. Take a cup of water at room temperature and lower the pressure on it enough, and it will boil from the heat your forehead gives off. Your forehead is not producing heat of fusion. At below the Triple Point of pressure (which varies from substance to substance) anything will sublimate directly from solid to gas, and at a lower temperature than
Yup it boils but do you know why it doesn't instantly boil? That's because you have to continue to apply heat until the latent heat of evaporation is paid. Let me make an example that you can actually test.
Take a cup of water and put it in a pan
Place the pan on a stove
Begin heating the water
Stick a thermometer in there
You'll notice that as the temperature approaches 100 C / 212 F the water will begin to boil. (funny it happens even before the average temperature reaches the boiling point)
You will ALSO notice that when the water reaches 100 C (well actually a little above thanks to mineral content) it doesn't all boil at once. You have to continue to add heat to the system in order to boil all that water. Now you aren't changing the temperature any (check your thermometer it won't do much more than budge aboce boiling) but you are still heating the system. THAT is the latent heat of evaporation: the energy you must pay in order to cross state boundaries. The energy is the same regardless of temperature and pressure requirements.
What's really funy is I did this shit in feyarking High School physics so I must guess your ignorance of such principles means either:
a) You are some little middle schooler who barely understands math let alone physics OR
b) You only passed physics by copying notes of the kids who aced the AP Physics test.
Some foolish Disciple of Darkstar wrote:Sure, and your scaling is done by who? The engineer who claims heat of fusion is needed in space?
Actually I've done scaling on my own and a 40m spherical asteroid is actually small for some of the asteroids we see vaped. Several others have performed similair scaling and the results fall within a consistent range.
Some foolish Disciple of Darkstar wrote:And that means what? Idiot, you tried to claim that somehow the luminosity of the asteroids somehow contradicts them having a vacuous internal structure. Now you try to weasel out of it?
I won't pretend to understand this whole debate but I'll make the point of albedo very clear:
It tells us what kind of asteroids we are dealing with.
Now from our own studies of asteroids (and by our I mean the Earth's scientific community) we have managed to garner evidence on everything from composition relative to color spectrum to density estimates and the like. Now in the case of the asteroid in question we have the additional benifit that there is an observer in this asteroid field (Dengar in Tales of The Bounty Hunters). he specifically states that the asteroids are, largely at least, nickel-iron. This generally classification limits us to certain composition and density constraints. If you have ever researched the subject you'll note that asteroids such as these (formed in high energy planetary collisions) are the cooling results of the liquid elements sitting around after such a collision. Such asteroids tend towards greater density as well as significantly higher heavy metal composition (which are themselves very dense).
This combined evidence has led to the clear idea that these asteroids are likely very dense (Nickel-Iron asteroids are made of one of two mineral compositions both of which are roughly 7900kg/m^3). Basically if you want to say these asteroids are lower in composition you better study the asteroids in question (not the super continent sized chunk the Falcon flew into as the two are dissimilair in too many ways to count).
Some foolish Disciple of Darkstar wrote:Ah, your memory is so fleeting, and your brain so ineffective. I did mention that, although most of the planet is molten and the majority of it would have such a foamy internal structure, major chunks of the crust would not be molten at the time of impact and thus would retain the solid nature.
Some foolish Disciple of Darkstar wrote:What does that have to do with what I just said you idiot? Notice my quote, I?m talking about real-live volcanic rocks and how a pressure change causes gas to bubble. Then you mumble something about iron mixing in as if that?s relevant. Idiot, the iron is already mixed in with it, and even if it was how does this affect the basic argument?
1) I don't understand why you are trying to explain a cosmic collision with allusion to minor geological events on our little planet. If two planets were to collide the energies would be immense and a huge amount of material (and not just the molten core of many terrestrial worlds) would be heated into vapor or liquid form. The further evidence provided by official observation (TOTBH) and examination of the available evidence (TESB and TESB:SE) indicate compositionand density figures, see above.
2) I really hope your first quote wasn't as ignorant as it looked.
Some foolish Disciple of Darkstar wrote:In vacuum, water flash-boils at it?s melting point, not it?s boiling point. Idiot, of course you have to pay energy for every gram vaporized. The thing is, the lower the pressure, the less energy you have to actually pay. Even you?ve managed to agree that less heat is needed in lower pressure, how you can possibly say that and then claim that the same amount of energy is needed is beyond me.
Your ignorance is available in bounds. See above but I'll repeat for sheer fun:
1) Energy need to reach boiling/melting point is near zero
2) energy needed to pay latent heat of fusion / latenet heat of evaporation DOES NOT CHANGE.
Some foolish Disciple of Darkstar wrote:Oh, and you claim that stone requires more energy to vaporize than iron. Most interesting, obviously whoever this Mike Wong is disagrees, I notice he has an asteroid calculator on his site designed to show how much energy is required to destroy them. Let?s see, 40 meter asteroid:
Granite:
Melt: 49.3 kilotons
Vaporize: 245.9 kilotons
Iron:
Melt: 80.4 kilotons
Vaporize: 479.1 kilotons
At this point the level of dishonesty you?ve displayed is nothing short of amazing. You lie about everything in order to get your way, don?t you?
He's most likely refering to some of the likely rocky compositions of the asteroid which will include amouns of silicon. Now lets see how silicon staks up against Iron for thermal data:
Silicon: Si
Weight: 28.08 g/mol
Melting Point: 1687 K
Specific Heat: 18.81 J/K*mol
Latent Heat of Fusion: 50200 J/mol
Latenet Heat of Evaporation: 359000 J/mol
Iron: Fe
Weight: 55.84 g/mol
Melting Point: 1811 K
Specific Heat: 25.1 J/K*mol
Latent Heat of Fusion : 13800 J/mol
Latent Heat of Evaporation : 347000 J/mol
Some foolish Disciple of Darkstar wrote:Let's take a good look here. Do you see any liquid phase past the triple point? Of course not, because as I've said over and over, as pressure lowers the boiling and melting points become the same and matter goes directly from solid to gas. I don?t know how many times I?ve had to point this out now, obviously your stupidity extends well beyond your lack of science, or else you?re just using a wall of ignorance. At the Heat of Fusion Temperature (Actually well below that in vacuum) the material directly sublimates from solid to gas. As I?ve said over and over, stupid. And although you would want to put more than heat-of-fusion energies into something to make sure it doesn't recool into a largely solid mass, you also don't even need heat of fusion to actually melt it in low pressure, making even heat-of-fusion a generous estimate.
You really don't understand latent heat of fusion and latent heat of evaporation do you? See the kitchen stove example again.
Some foolish Disciple of Darkstar wrote:1: Asteroid Density:
We already know, thanks to Righteous Fist of Heaven, that the asteroid field was made up of two colliding planets.
What do we know about planets? They tend to have a solid crust with a molten interior. The interior is under vast pressure from the surface pushing down on it.
What happens to a liquid under pressure when the pressure is suddenly released? Dissolved gasses in the liquid bubble out violently. This holds true for everything from a suddenly-opened champagne bottle to a diver who gets the bends when he rised from the depths too quickly (Dissolved gas in his blood bubbles) to hot lava, which bubbles and usually winds up freezing as foamy rock like scoria or pumice which actually floats on water. Certain volcanic stones, notably Obsidian and Basalt, have few bubbles, but they typically are from long-standing flows in which the gas has had time to escape before the lava cooled.
We know from volcanoes alone that underground magma has loads of such dissolved gas in it, typically sulphurous fumes. Upon shattering in the impact, the core and the mantle of the planet would go from unholy amounts of pressure to almost none, while simultaneously being exposed to such low pressure that they would exceed their boiling point. As the gasses turn the liquids into froth, they boil with their own vapors and freeze at the same time from evaporative cooling. The net result is quite likely to be asteroids that are almost entirely vacuum or diffuse gas with little solid material, asteroids, in short, with density lower than water. The crust would, of course, be mainly solid fragments so you'd wind up with a few of those mixed in the batch.
I won't pretend I'm not laughing at this. You actually believe that when two FUCKING PLANETS collide that they will not release ungodly amounts of energy? With the energies involved you are going to get huge volumes of liquified planet that will bear little if any semblence to their former state of affairs. The resultant asteroids, as they cool, will still form mineral formations jsut as they did to form our world in the first place. What does this mean?
1) If you are foolish enough to believe that the low energy events (relatively) like lava boiling out of the ground at all resembles the collision of two planets well then...shite I can't even find words to describe how stupid you would be for still thinking that.
2) Until you learn a little about asteroid formation, identification, and composition I'd ask you to refrain from pretending you understand what is going on.
3) Your continued ignorance of basic thermodynamic principles, laws, and terminology is so laughable I question how you can oeprate a computer safely with that little brain power.
Some foolish Disciple of Darkstar wrote:The result for our debate? The TESB Asteroid shot could easily have been against a very lightweight asteroid with a density lower than styrofoam. This fits:
A: Scientific and observed facts (Real-life examples pointed out above).
Before you say real-life examples please chose some that actually apply to asteroids formed by the collision of two planets as oppossed to volcanic rocks.
Some foolish Disciple of Darkstar wrote:B: All canon and official information (Doesn't contradict Darksaber, doesn't contradict ANH, doesn't contradict TESB, fits with "Asteroids were planets" theory, Doesn't contradict numerous "Terajoules of Firepower" quotes.) The only real sticking point against this is the "Megaton Compression Bomb" bit, but we have no idea what a compression bomb is or why an asteroid would mysteriously explode, which suggests some sort of shield interaction.
I hope you aren't daft enough to think you have miraculously overrulled ANH's half a starfleet quote. I will further hope you just ignored ROTJ's "thermonuclear explosions" quote. After that I hope you just forgot about the amount of energy neccessary to move the Falcon off axis in TESB (which suggest anti-fighter firepower in excess of the numbers suggested here).
Beyond all this I'm sure that you realize a low-density asteroid by itself SPECIFICALLY and DIRECTLY contradicts Dengar's statement from Tales of The Bounty Hunters.
Some foolish Disciple of Darkstar wrote:As we've pointed out repeatedly, using all the canon is superior to ignoring some and picking and choosing. This explanation fits all the canon and known science. It is the superior theory, since yours does not fit all the facts, contradicting Darksaber.
Huh? See above you crack smoking donkey fucker.
Some foolish Disciple of Darkstar wrote:1: ICS Hulls vs. Asteroids: We see quite clearly an asteroid wiping out a Star Destroyer.
Wrong, the outline of the bridge tower is CLEARLY visible, in other words the asteroid hit the bridge (which was unshielded) as didn't manage to do anything other than damage the communications and make an officer cower in fear.
Some foolish Disciple of Darkstar wrote: The ICS, however, describes hulls with immense strength alloyed with neutronium. Even with the shields down, such armor should laugh at asteroids. Yet it clearly does not. This is conclusive proof that either: The ICS is contradicted and should be ignored (I dislike this option on principle, I like using all the canon) or else the ICS refers to ships far more powerful than the Empire's best weapons (The most reasonable explanation that doesn't contradict any canon.)
Alternatively you just didn't look at the evidence properly and assumed. Thus making an ass out of you (but not me I know better). Damn you really deserve the title you now have you crack smoking donkey fucker (TM)
