Continuation The Electric Comet Theory Boogaloo (Part 2)

[jonesdave116]

Static electricity may transport dust across airless planetary bodies



So this is all new to the mainstream then????

No wonder the mainstream are surprised

but how does that relate to 67P you ask...

Sorry RC, JD116 but your "dust" entrained in "sublimating subsurface "ices"" may NOT be the only mechanism at work here.

Strewth, Sol, don't you ever give up with this nonsense? Can you please tell us what Wal predicted for the Halley encounter? Or was he still involved in some activity which didn't involve science at that time? Perhaps you could tell us when he, or any other con artist from EU, has ever been involved in science? At any time?
Is not what they say purely post-dictions? We told you this would happen (no you didn't); EDM explains that (no it doesn't).
Maybe you could give us a list of EU advocates who actually understand cometary science, and lay out their qualifications, previous publications, missions etc.
And you wonder why nobody takes this nonsense seriously? Apart from a total lack of evidence. And a shed load of evidence that says Wal and Dave are talking rubbish (i.e. lying)?
Other than that, I mean.
Anything?

Phaethon confirmed as rock comet by STEREO vision

The Sun-grazing asteroid, Phaethon, has betrayed its true nature by showing a comet-like tail of dust particles blown backwards by radiation pressure from the Sun. Unlike a comet, however, Phaethon's tail doesn't arise through the vaporization of an icy nucleus.

The team believes that thermal fracture and desiccation fracture (formed like mud cracks in a dry lake bed) may be launching small dust particles that are then picked up by sunlight and pushed into the tail. While this is the first time that thermal disintegration has been found to play an important role in the Solar System, astronomers have already detected unexpected amounts of hot dust around some nearby stars that might have been similarly-produced.

So, is Phaethon an asteroid or a comet? Asteroids and comets derive from entirely different regions of the solar system; asteroids from between Mars and Jupiter (roughly 2 to 3.5 AU) and comets from the frigid trans-Neptunian realms (30 AU and beyond).

"By the shape of its orbit, Phaethon is definitely an asteroid. But by ejecting dust it behaves like a 'rock comet'," said Jewitt.

An' wot is you say'n?

 

[Andy_Ross]

He's saying scientists can tell the difference between an asteroid and a comet but he can't.

 

[Reality Check]

Just say'n

Just saying that you still ignore the real world for the delusions of the Thunderbolt cult, e.g. that comets are rocks or the liar Wal Thornhill's denial of gravitational waves, Sol88?

Phaethon confirmed as rock comet by STEREO vision is not an ignorant delusion that that asteroid Phaethon is a comet or that Phaethon's dust tail is the gas from sublimating ices + dust forming a comet tail.

The parroting of the Thunderbolt cult ignorance, delusions and lies in this thread alone (continuation of a thread that is now 7 years of delusions from Sol88 and Haig!).

An' wot is you say'n?

In addition to single particles, clusters of dust were lofted, which showed that electrostatic processes may be responsible for the Rosetta detection of fluffy dust particles released from the surface of Comet 67P.

These laboratory observations reveal that dusty surfaces can become smooth due to dust mobilization and could help explain the formation of the "dust ponds" like those seen on asteroid Eros and comet 67P, and the unexpectedly smooth surface on Saturn's icy satellite Atlas.

Sublimation not needed, nor collisions but you do need a plasma with charge separation...

and it took the mainstream 50 years to a least entertain the idea!! talk about slower than a wet weekend

 

[Reality Check]

If you are ignorant enough to think that the asteroid Phaethon is a comet then you are free to make up as many delusions you like. Just do not expect rational, knowledgeable people to believe you.

Multiple lies about Static electricity may transport dust across airless planetary bodies

1. Not about "a plasma with charge separation".
2. Not about the formation of comet tails (your last delusion).
3. The mainstream have been looking at the transport of dust across airless planetary bodies in general since at least 2001.
   Particle Levitation in a Plasma Sheath Above a Surface
   

   Dust grains suspended above the lunar surface have been observed on multiple occasions. Virtually all small, airless bodies in the solar system are coated with a dusty regolith; therefore, charged dust particle levitation and transport may also occur in planetary ring systems, on Mars, Mercury, planetary satellites, asteroids, and comets. The interaction between charged dust particles and a photoelectron layer or plasma sheath above the surface is the most likely explanation for these dust dynamics.

   And across the Moon's surface since at least 1962.
   Electrostatic Dust Transport on the Lunar Surface by Singer, S. F.; Walker, E. H.; Icarus, Volume 1, Issue 1, p. 112-120
   

   Abstract
   Rapid erosion processes have sometimes been postulated to exist on the lunar surface. We show that the most favored process, electrostatic erosion, is not valid. Meteor impact produces a much smaller erosion due to mechanical crushing; its effectiveness is calculated. We also calculate the velocity distribution of the dust particles ejected from the impact. By considering in detail the charging of these dust particles we can show that a fraction of them will be reflected elastically by the strong electric field in the lunar electronosphere. This process leads to a limited amount of fluidity of the dust. We conclude that the mass of dust which is "floated" and eventually redistributed forms between 1% and 10% of the incident meteoric mass. Over 5 billion years the total amount transported is of the order of 0.4 to 2.0 gm/cm 2 and produces an average layer thickness of 20 to 100 cm in shadow areas. The surface density of hopping dust particles is between 10-100/meter 2 on the sunlit hemisphere. Dust is deposited preferentially in shadow areas such as crevaces.

Good on ya RC!

The interaction between charged dust particles and a photoelectron layer or plasma sheath above the surface is the most likely explanation for these dust dynamics.

now you're getting it!

 

[Reality Check]

now you're getting it!

The insult that I am as ignorant or deluded as you, Sol88 !
I have known about dust transport on the Moon, etc. for several years now.
I know how to learn about science rather then relying on the deluded Thunderbolts cult like you, Sol88.

You did not apologize for the multiple lies about Static electricity may transport dust across airless planetary bodies.

The parroting of the Thunderbolt cult ignorance, delusions and lies in this thread alone (continuation of a thread that is now 7 years of delusions from Sol88 and Haig!).

A new paper out regarding the observation of an outburst at the comet. As luck would have it, most of the relevant instruments were looking at the area in question at the time:

The 19 Feb. 2016 Outburst of Comet 67P/CG: An ESA Rosetta Multi-Instrument Study

http://mnras.oxfordjournals.org/content/early/2016/08/24/mnras.stw2088.full.pdf+html (free access)

From the abstract:
"On 19 Feb. 2016 nine Rosetta instruments serendipitously observed an outburst of gas and dust from the nucleus of comet 67P/Churyumov-Gerasimenko. Among these instruments were cameras and spectrometers ranging from UV over visible to microwave wavelengths, in-situ gas, dust and plasma instruments, and one dust collector."

Goes without saying that nothing electrical happened.

It's obviously as the the PR states

In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.

Sublimating dirtysnowball model still intact!

but...

Sublimation model got some splan'n to do, ay!

In addition, MIRO recorded a 30ºC rise in temperature of the surrounding gas.

lINK along with all the other data screaming an electrical discharge...

Telling it was along a cliff line with a distinct terminator in the area of the outburst... just like on other airless bodies immersed in the solar plasma (solar wind)

Telling JD116, very telling

 

[Sol88]

Well done the the ESA team for letting the cat out!

Should raise, at least, the question on whether the sublimation model is the correct one!

 

[Sol88]

None of which is getting within cooey of the frigging comet. So your point IS?

So what is this plasma supposed to be doing, Einstein? Why are we not seeing it? What does it need to do, that sunlight heating already observed surface and subsurface ice can't do? What exactly is it, and where is the EVIDENCE??????

Ummmm... The 19 Feb. 2016 Outburst of Comet 67P/CG

Well, that's for us to know and for you to ...

What evidence are you talking about? Neutrals outnumbering electrons (and therefore ions) by 5 orders of magnitude? Gas temperatures of -220 C? Perhaps you could point out where this evidence actually is. I've read the paper and I saw nothing, and I doubt anybody else can see any either.
Please explain.
