• All comet nuclei that have been directly observed have proven to be rocky with no visible water present on the surface.[51][52][53][54][55] The so-called "jets" of comets are observed to be highly collimated.[55] The dust of comets is observed to be extremely fine.[52] Samples of comet dust show particles that have undergone intense heating.[56] The impact excavation of Tempel 1 show no water ice beneath the surface.[52] These observations refute the standard theory of comets being a dirty snowball ejecting sub-surface water ice and dust via sublimation.
Further, direct observation of water in space show it to undergo instantaneous boiling followed by instantaneous freezing into micron sized ice particulates (desublimation). If water vapor itself was being sublimated on comets we should expect to see actual ice crystals in cometary comas, not ionized water and organics. No in situ experiment has ever demonstrated how or why sublimated water ice in space should undergo instantaneous ionization. Desublimation is what occurs to water vapor in space, not sublimation.[57] The end result of ice "melting" from a comet should be extremely fine solid ice crystal particulates - this is not observed in comets. Waste water ejected from spacecraft instantaneously desublimates, it does not magically ionize into a glowing plasma coma.
Comets are also observed to emit x-rays and have filamentary tails. This is unexplained by the standard model, yet these observations were predicted by cosmologists that took electric forces into account. Supporting articles from a wide range of sources can be found here.[58][59][60][61][62][63][64][65][66]
• All comets observed falling into the Sun or passing very near the Sun have subsequently been followed by coronal mass ejections, some of which actually "disconnected" the tails of comets from the nucleus. This is not explained at all by the idea a comet is a dirty snowball, yet this is well explained by electric cosmology’s view of comets. Also, comets have observed to brighten at distances too far from the Sun to possibly be attributed to sublimating ice. This too is explained well by electric cosmology’s view of comets.[67][68]
Further, magnetic reconnection is invoked to explain tail "disconnection" events and other obvious electrical phenomena observed in comets. As was demonstrated in a previous point, magnetic reconnection violates conservation laws in physics and is nothing more than a blatant reification of MHD simulations.

what do yo mean they are obviously electrical in nature? they have electricity inside them?
or that them passing though radiation/other light at speed. creates or collects electricity/megnetic feild.
or something else.
i understood most of the article but this.

I went to Physics college, didn't get the degree because I had some issues by the end of the last year, but I got the gist. Went through all the basics of Physics Mathematics, up to general relativity....
Now, I am halfway through the video Thunderbolts of the Gods, which explains [most?] of the "electric universe theory", and man: it's really mind bending.

The combined observations show a complex mix of silicates, water and organic compounds beneath the surface of the comet. These materials are similar to what is seen in another class of comets thought to reside in a distant swarm of pristine bodies called the Oort Cloud. Oort Cloud comets are well preserved fossils in the frozen suburbs of the solar system that have changed little over the billions of years since their formation. When they are occasionally nudged gravitationally toward the Sun they warm up and release a profuse amount of gas and dust on a one-time visit to the inner solar system.
“These observations give us the best glimpse yet at what’s under the dusty skin of a comet,” said David Harker of the University of California, San Diego who led the Gemini team. “Within an hour of impact, the comet’s glow was transformed and we were able to detect a whole host of fine dusty silicates propelled by a sustained gas geyser from under the comet’s protective crust.
If warmed sufficiently, their surface ices sublimate and escaping gases can entrain small dust particles, together forming the often spectacular tails of dust and ionized gas seen from Earth
you are telling me these comets have been around melting for millions of years throwing out ice an dust for millions of years

Water and other volatiles were ejected from the impact site for a long while after the impact.

Here is a detailed report on the results.

It's pretty clear that this event did not produce a gusher," said SWAS principal investigator Gary Melnick of the Harvard-Smithsonian Center for Astrophysics (CfA). "The more optimistic predictions for water output from the impact haven't materialized, at least not yet.
SMA measurements corroborate the SWAS findings. Although the SMA wasn't tuned to frequencies of water emission, which are difficult to observe from the ground due to atmospheric water vapor, it watched for other chemicals such as hydrogen cyanide. SMA astronomers saw little increase in production of gases following the impact. Gas production rates remained so low that they could set only an upper limit on the total.
"All we needed was a factor of three boost from the impact to get a definite detection," said Qi. "We didn't see that."
Keck got that factor of three immediately after the impact.
"The big picture will emerge once astronomers meld data from different observatories at different wavelengths," said Melnick.
"SWAS operators were puzzled by the lack of increased water vapor from Tempel 1. Post-impact measurements showed the comet was releasing only about 550 pounds of water per second-an emission rate very similar to pre-impact values, and less than seen by SWAS during natural outbursts in the weeks before the impact."
"The water column numbers extracted
from these postimpact mean spectra are in
agreement (within their confidence limits), and
they are larger than the preimpact column
number for H2O by about a factor of 2"
