Also explains those whit outs as you call them go look at deep impacts website they have a moving animation as they go over the horizon you see its escaping gas. For some reason your either unaware of a decade of science or choose to be not sure which.

Sorry buddy, that's not how the standard theory of comets says erosion works on comets. However, if you want to throw the standard theory under the bus, be my guest.
The standard theory says the surface of comets is solid rock, with huge pockets of ice being trapped beneath the surface. Ice sublimates out of vents at great pressure, causing the observed discharges. Therefore, any surface erosion that occurs must be related to a vent that is discharging.
Do you see any vents discharging a fountain of gas under high pressure in those images? Go ahead and point them out to me, because NASA didn't find any. Only 0.5% of the surface was found to be ice. The whiteout areas are not discharging gas vents, that much is obvious, and I can cite NASA's own papers proving as much.
www.astro.umd.edu...
"Each of the jets appears to emanate from a dark spot (designated by letters a–d in the
third panel) adjacent to brighter material. In the fourth panel, regions where exposed
water ice was detected are overlaid in blue for comparison"
NASA thinks the jets come from dark spots. Obviously they are wrong, because the jets they are observing are actually coming from the adjacent white spots, which are plasma discharges. NASA correlates them with ice in the spectra due to the elctro-chemistry taking place between silicates and the electric discharge machining.
Remember, a vent must come from a hole in the rock. Therefore, it is impossible that a bright surface feature could be the source of a jet - at least according to the standard theory.

Given that the spectrometer has a two dimensional detector, it is possible to make a map of Tempel 1 at the wavelength of the ice absorption bands. That map shows that the bright regions in the UV are correlated with dark regions in the near-IR where water ice absorbs light. Since the visible images have a higher spatial resolution, we use those images to calculate the extent of ice on Tempel 1's surface. That turns out to be a small fraction of the surface, only 0.5%....What is significant is that the extent of this ice on Tempel 1's surface is not sufficient to produce the observed abundance of water and its by-products in the comet's coma.
Comet Borrelly has plenty of ice beneath its tar-black surface, but any exposed to sunlight has vaporized away, say scientists analyzing data from Deep Space 1, managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif.
"The spectrum suggests that the surface is hot and dry. It is surprising that we saw no traces of water ice," said Dr. Laurence Soderblom of the U.S. Geological Survey's Flagstaff, Ariz., station, lead author of a report on the Borrelly flyby results appearing in the online edition of the journal Science.
Scientists thought most comets were "fluffy" snowballs -- piles of icy rubble that were loosely bound together. But Wild-2 has a solid, cohesive surface carved into lofty pinnacles, deep canyons and broad mesas.
"It's completely unexpected. We were expecting the surface to look more like it was covered with pulverized charcoal," says Donald Brownlee, a University of Washington astronomy professor and Stardust's principal investigator.

On the other hand, could a dry rock that contains no volatiles create such huge comas and tails seen in comets? I'd like to see a lab experiment where a rock is placed in vacuum and made to create a coma and a tail.

That's funny, because I'd like to see an experiment that shows photodisassociation can occur at the rates assumed by the standard cometary models.
The same mechanism that the EU proposes creates comet tails is what standard theorists say creates OH and H2O2 in the martian atmosphere.
"We investigate a new mechanism for producing oxidants, especially hydrogen peroxide
(H2O2), on Mars. Large-scale electrostatic fields generated by charged sand and dust in the
martian dust devils and storms, as well as during normal saltation, can induce chemical
changes near and above the surface of Mars. The most dramatic effect is found in the production of H2O2 whose atmospheric abundance in the “vapor” phase can exceed 200 times
that produced by photochemistry alone. With large electric fields, H2O2 abundance gets large
enough for condensation to occur, followed by precipitation out of the atmosphere."
Electrochemistry is a well developed field of study. We know with total certainty that it is possible for solid rock to discharge OH, and the other organic compounds seen in comets, through electrochemistry.
It's nice to see the standard theorists taking a page from the EU theory's playbook with that paper on martian electrochemistry. Indeed, EU theory says the martian "dust devils" are actually electrical discharge events. The EU theory's explanation for OH, H2O2 and other organics in the martian soil, is virtually identical to that paper. The only difference being the driver of what causes the electrical discharge in the dust storms.

Originally posted by dragonridrWrong this has nothing to do with EU it has to do with static electricity caused when martian sand is blown into the air. Just like rubbing your feet on the carpet if the atmosphere is dry it creates static electricity which according to physics can be used to create ionized particles.Its called electrostatic modeling and mind you just a theory this actually occurs. Please tell me what this has to do with a comet???

That's not a readable paper, its just a bunch of slides. Further, I don't want theoretical math, I want to see a paper showing photodisassociation rates that match comets produced in a laboratory.

Apparently you're not capable of understanding the paper I just showed you. I'm wasting my time arguing with you. You ignore the data provided by Franklin Anariba in the OP video, and you can't seem to grasp that the electrochemical processes that the EU theory says produces comet tails are the exact same processes put forth to explain the martian surface findings. They differ in location, but not in function.

You asked how it was possible for a solid piece of rock to emit the coma of a comet.
I just showed you how it was possible through electrochemical interactions.
If you can't put two and two together, it's not worth continuing this conversation with you.
Obviously comets do not have atmospheres, but if EU theory is correct, then obviously electrochemical interactions with the rock can produce the coma, which is what this entire thread is all about. You don't need an atmosphere to have electrochemical interactions. They can happen in a complete vacuum.

So you concede you put information out there that has nothing to do with comets since you admit they dont have an atmosphere. And then you go further and say that charged protons is going to cause a chemical reaction in a rock?? Ok please provide some research that shows rock turning into a gas. You realize the paper you showed was discussing plasma so please tell me how these plasmas form on a comet ? Please show me an experiment in a lab that confirms your theory unlike the last one which quite frankly you were being disingenuous.
OK please show some research of a rock ionizing into a gas

Well, the Curiosity Rover carries a laser that ionizes rock for analysis....
No real need for any research here:
"For hundreds of years people have known about the therapeutic properties of salt crystal and have used it for healing and air purification, according to the Poland Chamber of Commerce. Salt crystal is a natural ionizer, producing negative ions that bind to particles in the air and cause them to fall to the ground, creating purer air quality. Various experiments, such as studies performed by Dr. Albert P. Krueger and Dr. Richard F. Smith at the University of California on allergens and cancer research, show that the process of ionization can benefit health and well-being." ( Disclaimer: If you read that last line carefully, you will notice that they do not say that experiments show rock salt candles ionizing, simply the ions themselves have a beneficial effect)
Now, you can go online and find claims from various researchers claiming that there is no way that these things are producing ions or they would be leaking chlorine gas, but those same claimants have done no research into it at all that I can tell. They simply redirect you to issue after issue of semi related got ya's and never really say anything of their own.....
Misdirecting to technicality after technicality is how you deal with small minded people in politics or in a court room and has no place here. If you were truly interested in sharing information and trying to discover the truth of something, one would not rely on technicalities to vindicate themselves.
Additionally, I find the idea of "rubble due to impacts" on a comet or asteroid mostly a joke. It is really painful to here people make this claim. We have many videos of small objects being impacted in space from, satellite collisions, small asteroid collisions.... NOT ONCE does the debris magically settle back onto the object....
It's beyond ridiculous, we have rocks from mars blown out to space here on earth, there is substantial gravity on mars especially when compared to a small asteroid, you're going to tell me that the debris settled right back down into the impact crater or onto the object anywhere at all? Leaving no ambient debris? Seriously?
You can't possibly have even stopped to think about that claim, so all the features we see on a comet are due to impact....sure that's why they stay on predictable orbits, after they make some unseen collision in the very dense region of space known as the outer solar system (man you can hardly even move out there without running into a rock), the space squirrels inside the comets use their supply or frozen water asteroid jet fuel to get the rocks back on track so they can visit earth to steal more nuts...
You going to try to tell me that these small objects would be unaffected in their orbitals from not only randomly gassing vents, but also impacts with other bodies? Get real.edit on 8-7-2013 by vind21 because: (no reason given)

Hi,
I'm new, but if I try to have an objective look at the whole thing, it is IMHO clear that both theories could be right.
And it is very hard to determine the truth, due to obvious reasons.
But as has been said before, and I'm also a proponent of this:
* Occam's razor is usually right
* Always chose the model with the best predictability, for this is very probably the right one.
In the light, that NASA was baffled upon the deep impact results and the fact that the PC proponents exactly predicted them, gets at least me to the conclusion, that it is much more likely that the Plasma Cosmology is right on this case than the standard model.
In the end a theory is only as good as it's capability for future predictions, and as it seems exactly there the standard model is lacking.edit on 16-7-2013 by hulli because: (no reason given)
