Again, this post is as good as any to introduce my comments
What are you talking about? Yet another quote from a press release, aimed at the layman? Picked up that trick from Thornhill have we? Try reading the science, just for a change:
[...]
BRIGHT ICE SPOTS ON THE NUCLEUS OF COMET 67PCHURYUMOVGERASIMENKO AS OBSERVED BY ROSETTA OSIRIS AND VIRTIS INSTRUMENTS
Barucci, M. A. et al

Not to mention (which Thornhill didn't!) the ejection of ice grains at Tempel 1 and Hartley 2.
So, I repeat; what are you on about?
While it may take some time to find them, it's not all that hard to cite published papers whose contents are clearly and obviously inconsistent with the "Electric Comet" ideas as published by T&T, Sol, MM, etc. Despite the fact that such "Electric Universe"-based ideas are almost wholly devoid of quantification, numbers etc.
However, I think there's a fundamental flaw in all the commentary on Rosetta mission results
1 from EU zealots, one that points directly at the anti-science nature of "the EU". A flaw which is rarely pointed out, and EU zealots rarely challenged on.
OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) produces (produced) images, which are calibrated data often displayed as a 2D array of pixels. To be of use in science, one must have confidence in data such as this; how can you be certain that it includes "photos of 67P/Churyumov-Gerasimenko", for example?
Specifically, given EU zealots' intense skepticism (or hostility towards, or hatred of, or ...) of "mainstream science" (particularly as it relates to comets), you'd expect they'd subject such data to "extreme vetting", wouldn't you? Starting perhaps with "how do we know that Rosetta was anywhere near 67P/Churyumov-Gerasimenko?"
AFAICS, no EU zealot has ever addressed this question, publicly anyway (maybe one did, in a post in the Rosetta blog?). And that, in and of itself, points to "the EU" being something other than science. You see, in "the EU", G is extremely variable (see
this ISF thread for details), and Rosetta ended up near 67/P after three Earth "gravity assists" and one Mars one, as well as two asteroid flybys. The relevant navigation, and burning of rocket fuel, relied not on "Thornhill's theory of gravity" but on Newton's. How is it possible - assuming "the EU" is fundamentally scientific - to accept that Rosetta "arrived at" 67/P, given that an incorrect theory of gravity was used to get it there?
This is just one of possibly thousands of questions I'd expect EU zealots to have asked about data from OSIRIS, to confirm to their skeptical minds that that data is what the Rosetta team says it is. How could radio communications between ground stations and spacecraft work, given that the IPM is permeated by intense "Birkeland currents" in "dark mode" (these power the Sun)? Why did none of the rocket motors on Rosetta fire unexpectedly, given the intense electrical fields it must have passed through? (that's just two of such questions).
"
OSIRIS comprises two cameras: a high resolution Narrow Angle Camera (NAC) and a Wide Angle Camera (WAC). Both are unobstructed off-axis mirror systems, equipped with two filter wheels containing 8 positions each, and with backside illuminated CCD detectors comprising 2048 x 2048 pixels with a pixel size of 13.5 µm." (
source) Per T&T (and Sol, and MM, and ...), 67/P is (mostly) rock, with a density waaay higher than that of ice, and that the apparent observed density (ice-like) is due to intense electric fields. Likewise, the streams in OSIRIS images are electric discharges (I think I got that right), which produce intense x-ray emissions far beyond what mainstream scientists expect. Etc. Given this incredible electric/electromagnetic environment, how is it that the OSIRIS CCDs weren't frequently overloaded? that the electronics were not fried? that the data not riddled with artifacts caused by stray electrons or x-rays?
And so on.
As I said, I don't recall reading anything by an EU zealot explaining how Rosetta's OSIRIS images are consistent with "the EU", in terms of how Rosetta got to 67/P, how OSIRIS obtained its data, and how that data was received here on Earth (do you, dear reader?). To not do a detailed analysis to address these fundamental questions, and yet accept OSIRIS' data at face value, is surely hypocritical in the extreme, isn't it?
No, it's not.
Because whatever the EU is, it isn't science; EU zealots merely pretend to care about objectivity, consistency, independent verifiability, ...
1 Not only Rosetta of course; almost all remote sensing space probes
