So even though you admit to incomplete knowledge regarding the subject, you insist that your point of view is correct? Just what sort of logic are you trying to foist off on us here?
If you had read my analisis in detail you would know what I was talking about. Maby. I may not have explained it at a level you can understand.
Oh, so even though you admit your commenting on something that you admit you don't know about, you insist that we somehow must be too stupid to understand your logic. Which is funny, because I never have this problem with Mike or Curtis Saxton when they explain stuff to me, and neither is exactly a sub-par intellect. Which means you are admitting to being technically complicated on purpose to confuse those debating with you, rather than attempting to explain to them. Typical tactic of a dishonest debator.
It does not mater what type of mass we are "vaporising" here only the quantity and the energy involved.
Type is important for determining mass (its only unimporttant if we know the mass independently - nice attempt to backpedal on asteroid composition, incidentally. For that matter, knowing the kind of matter we are affecting is also relevant in terms of melting points, specific heats and latent heats, since they differ frrom material to material.)
Moreoever, you ignore (as Mike pointed out) how temperature matters (since temperature, as well as latent and specific heats, are relevant to calculating the energy input.), and how this impacts what we observe. The temperature of a vaporized 20 meter asteroid will differ from the temperature of the vaporized casing of a far less massive nucler bomb for the same results and level of energy (if both the bomb and the asteroid involve X joules, and both result in vaporization, but since the bomb is much less massive than the asteroid, the bomb casing will be heated to a much higher temperature since the energy input is the same.)
Since the explosion did not exibit any of the various signatures of high energy detonations, then we must assume, (I hate that word.) that something else must have happened.
You continually insist the visuals do not match what we should see, yet you've provided no concrete proof of this or a satisfactory explanation why. In fact, anything you've proven the point that a high-energy vaporization occured (remember the bit about conventional explosives?)
The signatures that we should see from such a shot are;
1. Bright Light. Millions of times brighter that that seen in the films.
2. Fire Ball. A rapidly expanding sphere of incandesant gas.
3. Halo Effect. As the cloud of gas expands, it forms a halo or ring like object that we see.
As the mass gets larger, the effects mentioned above last longer. If the mass stays the same but the energy content gets larger the effects last longer. If the mass gets larger at the same time as the energy goes up then the effects last very much longer. Since we see a puff of smoke followed by some debreis scatering that only lasts .25-.3 seconds any normal person who had seen film of any similar shot ( explosive test) would conclude that the total energy reliesed was realitively small. Not in the kilotons or even tons of TNT that are being bandied about.
The asteroids are only heated to thousands of degrees, not millions, and the mass of the asteroid is far greater than the mass of a nuclear bomb of comparable yield. Your comparison is meaningless and your logic dishonest.
In the Turbo-Laser Canon analisis that I read on this site, and I am sorry if I did not give credit to it's author, who's name I can not remember, It mentioned that time was a critical component of the equasion. He was right, but not for the reason that he thaught. The time that the event takes to evolve and dissipate is much to short to account for the energies claimed. None of the mechanisms cited mater. They could all be correct. What is important is the time required to disperce the mass quoted. It simply could not have happened in .3 seconds, 30 seconds maby even 300 seconds.
Let's go over this again, shall we?
To calculate the energy required to vaporize a certain kind of mass:
a.) The temperatures involved (startting temp, melting point, etc.)
b.) Specific heat and latent heats (of fusion and vaporization - which is dependent upon the materials involved.)
c.) The mass involved.
Now, A.) and C.) are the only variables involved in the calcluations (latent and specific heats are dependent upon the material only, and will change based only on the materials involved.) when the energy involved is constant. This means that if the temperature increases, the mass must decrease by a corresponding amount (if the mass did not change but the temperature increased, the energy yield would increase.)
In the case of the asteroid, because the mass is substantially greater, the temperature will be much lower than with a less massive object (IE a nuke) vaporized by the same amount of energy.
Some have said that no nuclear tests were ever conducted in space. One other poster cited several at various altitudes and said that at least one in his/her oppinion was in space. The air is so thin at 40 Km altitude that for all intents and perposes it might as well be space as we know it. Heavy dence satilites can make more than a few orbits at this or lower altitudes while their orbits decay. By the time you get to 80 Km, satilites can last for years. One of those tests cited was at 400 Km. This is space for any purpose but arguing minutia. I have said go rent the vidio and see for your self if the effects shown in the movie resemble the nuclear shot in that vidio. I claim and will continue to do so that they do not. Therefore, there must be some other expliation, cannon or not.
ROFLMAO, so you expect people to go find the evidence to support your theory yourself?? Why the hell should you be exempted from providing the evidence yourself, as you were the one making the claim?
As a neutral observer, My interest in this debate is purely one of professional pride. I am a fan of both series and do not have my personal fantasy wrapped up in either one. My fantasies involve fast cars, skis, Ladies and big guns.
That merely makes you an unbiased idiot. It doesn't excuse the fact your claims amount to a pile of speculative bullshit.
P.S. for the uninformed out there, the Bright Light and rapidly expanding sphere of incandesant gas should be self explanitory, but the halo effect might be unknown to some of you. As a sphere of incandessant gas expands in space, there is nothing to push some of the atoms back into the center of the sphere. It therefore soon gets to be a near vacuum again. Since every atom gives off light in every direction, as you look at the center of the ball it is effectivly only two units of thickness, one on each side, and thus seems quite dull. However as the line of sight gets closer to the tangent of the surface you must look threw more and more layers of gas, each radiating it's tiny quotient of light, untill it apears very bright. Thus it looks like a halo or smoke ring. The size of this sphere will be dependant on the origional mass of the gas involved, but will be independant of the energy involved. It will be visible untill the density and energy are low enough that your eye can no longer percieve it. As more energy is added, the rate of groth increases but so does the luminosity thus making it apier to get much bigger.
And as already pointed out, the luminosity is going to depend heavily on the temperature (which for a given amount of energy will depend on the materials involved as well as the mass.) Adding the same amount of energy to two substantially different masses will result in substantially different temperatures, and hence the luminosity will *ALSO* differ highly.
