The Electric Comet theory

Not open for further replies.
One thing that occurs to me, and I'm posting this thought here rather than the Rosetta thread as it contains random thoughts of a carpenter rather than actual science:

A comet flies way the heck out away from the sun and dumps heat against the immense heatsink of the universe then comes back in toward the sun. That means the comet would be very cold in relation to the solar wind and various sparse gasses so would function as a condensation surface for those relatively warmer substances. So that would cause some amount of redeposit of material on the surface of a comet on the way back in.

As I say, just random thoughts of a carpenter.
 
Mainstream text book science that i read as a kid and young adult said comets were made of dust and ice formed from the leftovers from the formation of the solar system!!
...snipped incoherent rant...
Ditto, Sol88, and add in some astronomy courses that I took at university :jaw-dropp!
The text book science has not changed. Comets were made of dust and ice formed from the leftovers from the formation of the solar system!
 
So Electric Comet theory is nonsense but mainstream Magnetic Comet theory is good !!!
Wrong, Haig - the application of physics that actually works to comets is good.

The Electric Comet theory is nonsense because it is a set of delusions from the Thunderbolts cranks who cannot even understand basic stuff like the measured density of comets is less than that of rock.
 
Hi Reality Check
...
Some of the websites and webpages Haig has posted links to seem to be pretty slick, and the videos can't have been cheap to produce. Do you know where these three guys get the money they need to produce and maintain all this?
I can only guess, JeanTate - maybe from their book sales and revenue from web site and YouTube advertisements? There are the three main electric universe/electric sun books. Talbot has another book called The Saturn Myth.
And of course if you have a bit of a cult like Thunderbolts there is the possibility of member donations.

the Electric Universe view ...
is to replace science with ignorance and delusions, Haig :p.

Astronomy: Planets in chaos
The discovery of thousands of star systems wildly different from our own has demolished ideas about how planets form. Astronomers are searching for a whole new theory
...
A planet is born
In the search for an overarching theory, astronomers do agree that core accretion has some things right: planets are leftovers from the birth of stars, a process in which interstellar clouds of hydrogen and helium gas contract until their cores grow dense and hot enough to ignite (see 'Planetary standard model').

So it looks like Haig is trying to spam this thread with many posts containing material irrelevant to electric comets in order to avoid answering:

And more from the late 1970-1980 timeframe:--I did the modal analysis and testing for this spacecraft which investigated that very thing:
electrical charging of spacecraft – an effect caused by repeated passage through the magnetosphere and known to have contributed to several on-orbit satellite failures.

Concerning Rosetta, I’ve wondered about the startling rubble field on the surface of 67P, since it doesn’t appear that any comet investigator anticipated such a thing. What is the significance of this debris for our understanding of comets? And is anyone speculating on a connection to the formative process?
No significance, David Talbott.
We know that comets formed with the rest of the solar system. The "rubble field" is probably blocks of ice and dust. That sounds like common knowledge that would not be commented on.
ETA: calling the rubble "debris" may be wrong. That suggests something like a landslide. The rubble may formed in place. There is at least one crater that seems to have a rubble-filled floor though.

However the actual scientific data (not just images) will have scientists speculating on the formative process of comets and 67P in particular.

W.T. "Tom" Bridgman is an astronomer who has also written on the electric comet idea:

Electric Comets II. Of Water & Ice in November 23, 2014.
The second blog post has the comment
I've also heard some claims that the low density (0.4 gm/cm^3, less than water) of the comet nucleus inferred from the spacecraft motion could be the result of electrostatic repulsion between the spacecraft and nucleus.
If this is an actual electric comet claim then it reveals the proponents ignorance of their own claims :eek:!
To have a repulsion you need like charges. But their claim is that there should be electrical discharges between the spacecraft and comet - that needs separation of opposite charges.

Alternately: the electric comet theory predicts that the measured 0.4 gm/cm^3 is too large!
 
There is a good chance that it will be discussed next week in ESOC Darmstadt, where the SWT (Science Working Team) of Rosetta takes place, which I unfortunately cannot attend due to other duties.

I think I have seen a post on the Rosetta blog positing a very close pass by Jupiter in order to explain the sulfur. I have not seen it discussed any further, but then it is also not my specialization field.

I guess there can be all kinds of explanations for a rubble field, pick rubble up from somewhere, or outgassing breaking "rocks" off the surrounding surface, but that is just my speculation.

This week we have a 8 km flyby (give or take a km) who knows what we will see.

WOW! this IS a highly embarrassing image of 67P for the mainstream "Dirty Snowball / Magnetic Comet" model ...

Re: What is 67P made of?

The best indication yet of what 67P is made of is the famous CIVA image take by Philae of its final resting place, and in particular this extraordinary reprocessed version by Mattias Malmer which clearly shows the jumble of rocks and boulders which Plilae finally tumbled down into: http://mattias.malmer.nu/2014/11/civa-d ... epth_cues/. It is almost a 3D image, so good is the resolution of the in-depth perspective. Truly amazing, and no doubt highly embarrassing for the "dirty snowballers"! This is brilliant citizen science.

Wow, Haig, it is highly embarrassing for you that you still cannot recognize ignorance and delusions when you see them written down at the Thunderbolts forum :p!
You cite some idiot who is so ignorant that they do not know the measured density of comets and 67P in particular thinking that an image processed to emphasize depth cues somehow invalidates the mainstream model :jaw-dropp!
It is even more embarrassing that you remain ignorant about what the mainstream model is - it is not the "Dirty Snowball / Magnetic Comet" model. It is the "use all valid physics" model!

Comet_depth_cues is a beautiful processed picture of a comet made of ices and dust.

Thanks Tusenfem. Presumably comet specialists are considering a cloud of debris originally moving with the comet. That would circumvent the astronomical improbabilities of the 67P nucleus running into sufficient numbers of “rocks” in interplanetary space to create the debris field (the answer offered by LSSBB). Given the comet's low escape velocity (about half a meter per second), impacts at several km per second would presumably remove a good deal more surface material than they would leave behind. But material settling to the surface from a surrounding cloud of debris would not present the huge improbabilities of collisional scenarios.
 

"In 2000, he turned his attention to thermodynamics and astrophysics, demonstrating that the universality advanced in Kirchhoff's Law of Thermal Emission is invalid."

I suspect you have no idea what this really means, Haig, but I'll clue you in on the punchline: a violation of Kirchhoff's law of thermal radiation is equivalent to a violation of the 2nd rule of thermodynamics. In other words, Robitaille believes in perpetual motion machines.
