Continuation The Electric Comet Theory Boogaloo (Part 2)

[Sol88]

my co-authors seem to like it, just got some solar wind data helping me resolve two things
all info at the rpc team meeting next week (if i can get to budapest)
and of course at the agu fall meeting (but by then it should long be submitted)

Cool, Thank you.

71 days and counting being afraid of doing simple physics: 25 June 2015 Sol88: Use a impact calculator to calculate the size of the crater on a comet made of rock by the Deep Impact impactor.

@Reality Check

Was the crater, in the eyes of the mainstream and by extension you, of the expected size for a comet at say an average 80% porosity, and 0.6 g/cm3?

I heard somewhere the crater was smaller than expected. Is that your take on it Reality Check?

Because you quoted the below

According to the Thunderbolts cult, Deep Impact (a "rock") hit a rock. The size of the impact crater will be smaller than the measured size of the crater for a body made of ices and dust.

@Reality Check

@Sol88: Who cares about what looks like yet another delusions about comets? My guess is that this is a lie from the deluded Thunderbolts cult since that is where you get your "science" from.
The point is that you have the delusion that comets are rocks. So Deep Impact would have produced a crater the size of a rock hitting rock.
Thus 71 days and counting being afraid of doing simple physics: 25 June 2015 Sol88: Use a impact calculator to calculate the size of the crater on a comet made of rock by the Deep Impact impactor.

As anyone who is willing to think about the physics knows:
According to the Thunderbolts cult, Deep Impact (a "rock") hit a rock. The size of the impact crater will be smaller than the measured size of the crater for a body made of ices and dust. Rock is denser and harder than ices and dust!

Some science about comet 67P: How the duck got its neck: Rapid temperature changes from self-shadowing may explain 67P's unusual activity and shape

When Rosetta approached comet Churyumov-Gerasimenko last summer, both its shape and its activity were surprising. It looked like two comets welded together at a skinny neck. But just as surprising, to comet researchers, was the fact that the cometary activity appeared to originate within the neck.

Here's the reason that's such a surprise. The animation below was produced for Philae landing site selection, and it shows how much of the comet's surface was in sunlight at the time. Red areas are continuously illuminated, so are hottest. Cometary activity has to do with volatile materials (especially ices like water and carbon monoxide) being heated and sublimating. And yet the hottest regions on the comet -- its twin poles, one broad area on each lobe -- aren't making jets like the neck areas are. What gives?

A new paper published in the Astrophysical Journal by Victor Alí-Lagoa, Marco Delbo', and Guy Libourel presents a possible explanation. The three scientists do work in thermophysical modeling -- they use physics to examine how changes in temperature propagate through solar system materials, and investigate what happens to those materials as their temperature changes.

They asked whether the comet's unusual shape might have any effects on the temperatures experienced from place to place on its surface. They took a model of the rotating comet and looked at how its surface temperatures change as parts of its surface cast shadows on other parts, or reflect sunlight into shadowed regions, for four different dates. In their model, they found that while the neck area of the comet doesn't experience the most extreme temperatures, it does experience the most extreme temperature changes, where baking-hot sunlit surfaces are suddenly sunk into very deep shadows, and just as suddenly lit up again. ...

Basically: Rapid temperature changes = formation of cracks = exposure of volatile materials = comet jets.
This also gives a mechanism for the formation of a double-lobed structure. Initial shock cracking from a irregularity such as an impact crater should spread into a neck and sublimation would produce the lobes.

More news from 67P.
"Comet surface changes before Rosetta’s eyes"

"In the months leading to the perihelion of Comet 67P/Churyumov-Gerasimenko, Rosetta scientists have been witnessing dramatic and rapid surface changes on the Imhotep region, as reported in a paper to be published in Astronomy & Astrophysics."

Hopefully we can get some temperature data for this region for the relevant time period, and then we can safely put this electric nonsense to bed.

Keep on dreaming, jonesdave116!

Keep on dreaming, jonesdave116!

About putting it to bed? Yes, you're probably right. There'll suddenly be a new publication by Thornhill about "cold" electricity, or something equally silly!

Hopefully not dreaming that they might have done some temperature measurements in this region though. Difficult to make measurements on sudden phenomona, such as the outbursts a month or so back, but this has been ongoing for a while, so hopefully they trained a fair few instruments on the region.

Over a year at 67P teams of scientists working on the data and the best we can do is

The sublimation of volatile species is clearly an important factor, as colour images of this region reveal the signature of exposed ice on some of the rims of the newly-formed surface features. The rapid rate of expansion is unexpected, however: models of sunlight-driven sublimation would predict erosion rates of just a few centimetres per hour, and thus the scientists believe that additional mechanisms are required to explain the observations.

Just more look at bunnies! (Pictures)!!!



Still...

"scientists believe that additional mechanisms are required to explain the observations

" @2:22 is my bet on the "additional mechanisms"

Bwahahahaha! What exactly do you think your youtube link does? Exactly the sort of "look at bunnies!" thing you claim (incorrectly) that the 67P team is doing. Your attack is hypocritical as well as wrong.

And Thornhill is a fruitcake.

 

[jonesdave116]

my bet on the "additional mechanisms"

Which are? I'm not looking at youtube b*llocks. What are the predictions for temperature data in the region? What is the EU prediction for temperature data (if they got it) for the regions at the time of the active jets?
1000k? 5000k? 10 000K? That's what you're going to need. I'll predict now that the next set of temp data won't see anything much in excess of ~350K.
Time for the EU delusionists to put up or shut up. What will the temperature data show? No cheating by looking at the data for Hartley 2 when it was outgassing like mad.
Will Rosetta's upcoming foray out to 1500km find your non-existent double layer? Again, I'll predict that it won't. How about you?
Will they find any evidence of electrical activity on the surface between now and the end of the mission? I'll go with no. Care to actually make some predictions based on this idiotic nonsense, given that you're so sure of it?

So most of that page is the standard, run-of-the-mill scientific illiteracy and stupidity we've come to know and love from the EU crowd. But I want to bring your attention to a lovely and unusual bit of nuttery:

"the name Rosetta was evidently chosen because of its likeness to Rosetta Stone, an international language-based software company."

Looks like the illiteracy and stupidity is more than merely scientific.

My grandmother's name was Rosetta. It was likely named after her

Over a year at 67P teams of scientists working on the data and the best we can do is

This is actually the best that you, Solo88, can do: Write fairy stories about the science produced from the Rosetta mission and cite yet another deluded video from the Thunderbolts cult.

Comet surface changes before Rosetta’s eyes is oddly enough about changing images of 67P's surface !
You lie about this article by cutting scientific explanations:

The sublimation of volatile species is clearly an important factor, as colour images of this region reveal the signature of exposed ice on some of the rims of the newly-formed surface features. The rapid rate of expansion is unexpected, however: models of sunlight-driven sublimation would predict erosion rates of just a few centimetres per hour, and thus the scientists believe that additional mechanisms are required to explain the observations.

A simple possibility is that the surface material is very weak, allowing for more rapid erosion, but it is also possible that the crystallisation of amorphous ice or the destabilisation of so-called ‘clathrates’ (a lattice of one kind of molecule containing other molecules) could liberate energy and thus drive the expansion of the features at faster speeds.

That is 6 years (over 6 months of deluded videos) of relying on 10th April 2015: The ignorance, delusions and lies in the Thunderbolts web site, videos, etc. , Sol88.
