What observations? The paper is titled Runaway Subduction as Driving Mechanism for the Genesis Flood. What are the observations it purports to explain?
It is an attempt at formulating a rather fundamental alternative hypothesis of large scale geodynamics so that observations in geology and geophysics can be explained.
Here is a quote from Baumgardner
"A critical issue in any model for earth history that accepts the Bible as accurate and true is what was the mechanism for this catastrophe "
If you are going to keep insisting, and properly so, that science is not about beliefs then you should acknowledge that by this statement Baugardner disqualifies himself.
I don't think disqualifies is the word. If this were so, then it would be unfortunate if Wegener's primary reason for proposing continental drift was because the scriptural story of "Peleg's day" because according to you, continental drift would therefore be a pseudoscience. My point is that motivation has no bearing on truth or falsity. I think I have referred to the difference between epistemic reasons for belief (or of acceptance) and practical reasons. Baumgardner along with many other creationists (albeit, to a more ridiculous extent with many of these other creationists) have made the mistake of allowing practical reasons to bare on the truth or falsity of their hypotheses, but only epistemic reasons have such bearing. So then, a reason for motivation does not bear on the truth or falsity of the hypothesis being researched.
Ok, what observations would falsify CPT, How about the observation that oceans haven't boiled away and that there is life on earth?
I am getting tired of referring you to post 842, I've even memorized the exact post number. You've made the mistake of presuming that an instance of disconfirmation having numerous speculative auxiliary assumptions is actually an instance of falsification. It looks to me like you are not very good at hypothesis testing. I would expect more from a scientist.
I had presented an instance of considerably sure potential falsification earlier in regards to the yellowstone fossil forests. Indeed the auxiliary assumptions required to be true for my hypothesis test to be good may be flawed, but they are so much less speculative than those required to be true for your test of "if CPT" then "a sterilized earth".. and my test can be executed by rather routine experimentation. If I can convince my geochemistry professor to take us to Yellowstone, perhaps I will have to seek to perform this test.
Perhaps he has changed his mind. The link to the ICR page that had the main papers doesn't seem to work. I recall pretty clearly that he invoked accelerated decay to get around the 20 million years it takes the instability to develop.
I don't recall this and I had read the paper many times when I had a copy. I recall the assertion being essentially that the runaway instability can unfold on itself under present conditions on timescales of 10^7 years.
Yes and YEC generally invoke miracles such as accelerated decay to get around this problem for their "models".
Thats because many of them don't do science very well. The problem is that you think that this bears on the truth or falsity of the hypothesis.
Do you have any evidence for this occuring at all?
Well there is a thermal lithosphere
It's going to take a lot of recrystallization to get all the volcanic glass you must generate while blowing the oceans into space to shed nearly all the heat from the new crust and lithosphere.
There still is a lot of heat in the lithosphere and even crust. I would expect the crust to have been even warmer as well post-CPT. Do you know how gabbros behaves at 300-800[sup]o[/sup]C on timescales of millenia? I have not seen any such studies but I would predict that if CPT occurred in the way I have described, recrystallization would be an observed phenomenon.
Right and it will move into the oceans and atmosphere, which do not have the heat capacity to absord it without getting far too hot to sustain life.
I was talking about heat transfer beneath the lithosphere... you are just all over the place aren't you? Nevertheless, you have not and cannot answer the question of how much heat would be absorbed by oceans and atmosphere and so you continue making fallaceous statements.
It doesn't matter. The water gets hot and then heats the rest of the oceans and the atmosphere to the point that life can't be sustained.
Well it matters to someone who is actually trying to think about these things. Your reason appears to be very limited, however. I've explained your fallacy.
They will bouy to the ocean surface. They will be slowed down greatly by the ocean water an they will heat that water. They will emerge from the oceans and spread at high velocity radiating heat in all directions. A signficant fraction will condense to water, at least at first, transferring its latent heat of vaporization to the air. A tiny fraction of 1% of the total heat will be required to heat the air past the point life can survive and eventually the atmosphere will be converted to steam.
LOL. Just your guess which you have claimed is an instance of falsification. You haven't even determined the dynamics of these jets. lol, your quite the scientist...
Unless it escapes the earth's gravitational field entirely it will fall back returning its initial kinetic energy as it falls.
Not nearly as much energy that is required to eject it from a vent at hypersonic velocities. You seem to think that if you elevated the ocean to a few hundred km and dropped it to the surface of the earth the ocean would vaporize to steam as it was in freefall.
Heat will be radiated back to the earth and into space during the entire process. I have done these calculations before based on black body radiation but don't have time to repeat them right now.
Well then either stop making speculative presumptions as if they were instances of falsification or do the calculations. I have little interest in performing these calculations at the moment and for good reason (one which you clearly do not acknowledge). In order to calculate the amount of heat energy that will be removed from the lithosphere and be radiated to space (let alone where all of the heat will naturally be redistributed as a result of these process) you must first understand the dynamics of the subseafloor hydrothermal systems and mechanisms for crack propagation in the lithosphere and of recharge hydrothermal processes feeding the jets, the morphology of gas phase seafloor jets, turbulence mixing and conductive heat transfer in the jet walls during both a stage of gas-liquid contact (as the jets penetrate the ocean) and a stage of gas-gas contact in the atmosphere, jet velocity, elevation potential, layered atmospheric convection (especially in the upper atmosphere) as a result of these jets in the atmosphere, etc. Of course you don't even think you need to do basic napkin work to consider your speculations falsifications.
I find this ridiculous.
What "jets" are those? You have done nothing to show that such "jets" are anything more than a figment of Baugardner's imagination.
What else do you think would happen if enormous amounts of ~1700 K mantle rock directly contacted water at the bottom of a conduit submerged in ocean water?
This is quite ironic considering that Runaway Subduction was only developed to support a specific religious belief in a global flood.
No. Runaway subduction is a known theoretical phenomena in geophysics. I think you are trying to refer to Catastrophic plate tectonics by means of runaway subduction. Nevertheless, the point of my assertion, "
Perhaps if you began to understand that belief is not the business of scientists as scientist I would be a little more silent" is that beliefs like these have no bearing on the truth or falsity of the hypothesis.
It makes novel predictions. No life on earth is one of them. Evidence of boiled oceans is another.
nope.
What statements? The statements that a single continent broke up and the pieces raced to their current positions setting off the Biblical Global flood? If not that then what?
To phrase it like that would just be dumb. CPT is plate tectonics behaving catastrophically. CPT and PT share common statements, however CPT differs by proposing that plate tectonic processes
have not always occurred essentially the way the do now--it rejects many of the uniformitarian statements which have been retained in modern geology. It is a highly general hypothesis and clearly has implications for all aspects of geology, geodynamics, and geophysics.
It appears to me that catastrophic plate tectonics may have occurred on Venus, perhaps via a slightly different mechanism (eg. delamination or perhaps a surface process) and clearly had different surface consequences.
You propose a process that generates enough heat under the oceans to boil all the water in the oceans more than 10 times over
10 times over? no. I calculate 3-4 oceans max.
...and heat the atmosphere beyond the point life could survive thousands of times over and you say the it is only speculation that this would end life. Amazing?
Yes it is speculation. You sound a lot like the critics of Wegener when he was first proposing continental drift.
We are talking about organisms fastened to the bottom of the ocean and rapid subduction of that floor. Exactly when and how do you think the fossil record of sessile benthic organisms formed?
I think that the ocean was probably filled with such organisms in all places. I have no problem envisioning some of them being burried in oceanic sediments and many of those sediments being accreted to the sides of continents. Sessil organisms move around, they just move passively.
How did it get ordered in your model?
I don't know, it isn't really in my interest list at the moment.
How did all those layers of burrows form in your model?
It is difficult to formulate a good hypothesis with such sparse data and such a poor geologic and biogeographic explanation as had been presented by Morton. However I presume that it can be easily explained merely with a population of organisms just doing what they do.
How did the fossil record of land animals including trace fossils get formed in the CPT model.
Similarily. Organisms die and when doing what they do, they can leave traces to be preserved.
You don't embrace the heat problem because it can't be delt with in CPT.
I embrace the heat problem to a greater extent of respectability than you ever have. Your critique of the heat problem is more superficial than even many creationists have considered.
Your model needs to explain geology better than or at least as well as current models. One of the facts it must explain is the fossil record. You can't really get around this as much as you might like to try.
That isn't the problem. The problem is that you whine at the first site of seeming inconsistence. You seem to think that problem solving is inconsequential.
The heat I am referring to comes from the cooling of the new ocean crust and lithosphere.
No this is not what you were referring to. In this instance you were referring to the release of gravitational potential energy. Read back.
The idea that all this heat could be carried away by organized hypersonic jets without transferring even a tiny fraction to the atmosphere is abusrd and it doesn't begin to solve any of the other multitude of problems with the model.
It solves
numerous problems. Also I don't doubt that some of it was absorbed by the atmosphere. But HOW MUCH. I consider it very poor value judgement to cease considering CPT on this basis without relevant research, especially since, if true, this process could solve so many problems.
If it had happened none of us would be around to argue about it.
Don't you think this sounds a lot like the anthropic principle and tine tuning arguments doesn't it?
BTW, how do think any life did survive the catastrophy you propose? Was it in a big wooden boat captained by a 600 year old man by any chance? Is that your "scientific" explanation for the survive of life during a CPT induced global flood?
no. I am not arrogant enough to presume that I know. In the face of the fact that CPT is an underdeveloped hypothesis and thus is not even very well understood. Nevertheless, my current posture follows from my doubt that CPT resulted in the entire earth being simultaneously covered. I therefore do not think that 'global extermination' is an (especially scientific) vice of expectation for catastrophic plate tectonics by means of runaway subduction.
