No, Sol88, I an stating that you are totally deluded about comets and are making up fairy stories about "caverns".
So much ignorance and craziness in one small post, Sol88!
It would be extremely stupid to think that the results showing that comets including 67P are made of ices and dust ("dirtysnowball" for the simple minded) shows that comets are not made of ices and dust.
- Philae bounced a few times because of the low gravity and a hard subsurface.
- Philae ended up at a fairy random location and measured a minimum tensile strength of the ice there using the MUPUS hammer.
That means that it is likely that all of the ice below the surface dust is around that tensile strength.- There is no need of delusional "large voids" to account for the porosity of 67P.
All you need is the fluffy grains that have been detected or space between grains.
[*]We have measured that one node of 67P is a more or less homogeneous mix of ices and dust (without any crazy quotes).- The measurement of the porosity of that node has nothing to do with the surface structure which has been known for months before the CONSORT results.
- First detection of molecular oxygen at a comet
The presence of O2 is not accounted for in your delusions.
Just so I understand where you are coming from, Soll88, are you going to persist in the delusions that comets are rocks, etc. even when you know about the real world of comets. My guess is the answer is yes:
The parroting of the Thunderbolt cult ignorance, delusions and lies in this thread alone (continuation of a thread that is now 6 years of delusions from Sol88 and Haig!).
10th April 2015: The ignorance, delusions and lies in the Thunderbolts web site, videos, etc. mostly cited by Haig.
236 days and counting of fear of doing basic 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.
You do not make sense, RC.[*]We have measured that one node of 67P is a more or less homogeneous mix of ices and dust (without any crazy quotes)....It would be extremely stupid to think that the results showing that comets including 67P are made of ices and dust ("dirtysnowball" for the simple minded) shows that comets are not made of ices and dust.
Comets are known to be a mixture of dust and ice, and if fully compact, they would be heavier than water. However, previous measurements have shown that some of them have extremely low densities, much lower than that of water ice. The low density implies that comets must be highly porous.
Oh dear, Sol. Density is LOWER than ice? That must make it rock then, surely? Shall I link to Wallace & Gromit's definition of what a comet is? Nah......think it's already dead on its arse by now. Got anything scientific that we ought to be looking at?
I make more sense that a follower of the deluded Thunderbolts cult who has the insane idea that he can look at an image of a comet and tell what it is made of, Sol88.You do not make sense, RC.
!There are no large caverns inside Comet 67P/Churyumov-Gerasimenko. ESA’s Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery.
Comets are the icy remnants left over from the formation of the planets 4.6 billion years ago. A total of eight comets have now been visited by spacecraft and, thanks to these missions, we have built up a picture of the basic properties of these cosmic time capsules. While some questions have been answered, others have been raised.

But is the porosity because of huge empty caves in the comet’s interior or it is a more homogeneous low-density structure?
In a new study, published in this week’s issue of the journal Nature, a team led by Martin Pätzold, from Rheinische Institut für Umweltforschung an der Universität zu Köln, Germany, have shown that Comet 67P/Churyumov-Gerasimenko is also a low-density object, but they have also been able to rule out a cavernous interior.
jonesdave116 - let us not fall for Sol88's instance about being ignorant about comets as shown by the fact that he is admitting to have being ignorant about comet jets for over 6 years now.Let's take the "jets" again. You start.
No, Sol88, I an stating that you are totally deluded about comets and are making up fairy stories about "caverns".

The discovery of carbonates “creates problems one way or another,” he says. But if the mixing theory is true, “it would rewrite how we think about the solar nebula”.
The find came as a "big surprise", and challenges mainstream theories on the formation of our Solar System, said scientist Andre Bieler of the University of Michigan.

That is a lie, Sol88, since I have known for years that the dust contains clays, olivine, forsterite, carbonates, silicates, etc. as not expected from rock excavated from a planetary surface.You do know, don't you RC, that the dust you talk about contains clays, olivine, forsterite, carbonates and silicates

No granite.
No limestone.
No fossils.
The irrelevant topic of the detection of O2 has already been explained several times (even in your citation!) so I have reported your post as "An off topic question that is explained by what he cites so an attempt to waste peoples time.".

The crystals are in the form of forsterite. They belong to the olivine family of silicate minerals...
The findings might also explain why comets, which form in the frigid outskirts of our solar system contain the same type of crystals.
Sure thing, JD116
Let's take the "jets" again. You start.
Show me the peer reviewed paper/s on the mechanism on how the "jets" are produced and sustained on a comet.
This is will be a hoot!![]()
That is wrong, Sol88, the repeat of lies, ignorance and delusions over the last 6 years means that you are a permanently in my bad bookWhoo boy, in RC's bad books again!![]()
!
.The lie Sol88 is spouting again is that clays, olivine, forsterite, carbonates and silicates can only come from planets and so supports his delusion that comets are rocks blasted from planets in recent times. There is little point in trying to address such a persistent lie (a year old?).No excavation from a planet needed for olivine
It seems more that Sol88 does not care that we know that he is lying or at least blindly parroting lies from the Thunderbolts cult.I know but the lie has to be addressed every time he tries ti bring it back up.
He seems to think we won't remember.

Which jets are you talking about? Type 1; general jetting from flattish areas (i.e. fan shaped); type 2; more collimated, generally coming from rougher terrain; or type 3; highly collimated jets as seen around perihelion at 67P?
First off, explain what it is that you don't understand about the mechanism. Secondly, explain what you think it is that you are actually seeing (is it gas, or is it dust?). Thirdly, explain, preferably with the use of an equation, what you think the expansion velocity of H2O gas should be into vacuum.
Comets are known to be a mixture of dust and ice, and if fully compact, they would be heavier than water. However, previous measurements have shown that some of them have extremely low densities, much lower than that of water ice. The low density implies that comets must be highly porous.

The point is that you are still lying.
Your "clays, olivine, forsterite, carbonates, silicates, etc." are expected in comets. Comets are made of ices and dust. The dust comes from the formation of the Solar System. So the dust has the same composition as other remains of the solar system, i.e. asteroids.
The usual point about how deluded the insanity that comets are rocks blasted from planets in recent times is:
The parroting of the Thunderbolt cult ignorance, delusions and lies in this thread alone (continuation of a thread that is now 6 years of delusions from Sol88 and Haig!).

Oh, and just because it gets up everyone's nose, the implication they are highly porous must include clays, olivine, forsterite, carbonates, silicates, all the volatiles, etc
