Comet origins

Assertion 1 - A broad section of "science" needs a complete overhaul due to unecessary assumptions. These assumptions poison entire scientific narratives and lines of research.

The main crux of this assertion is that certain scientific narratives (eg.evolution) implicitly rely on assumptions (eg. about mutations) which rely on Occam's razor to *shift the burden of proof*. Alternative non-scientific narratives (eg. creation) more explicitly rely on assumptions (about God) in a way doubly damaging to science, because it affirms the faulty method (to use Occam's razor) while dismissing rock solid observations (the transformation over time of species from simpler species)

Thus the overhaul of science that I'm proposing involves accross the board  reversal of incorrect usage of Occam's razor and a distancing of science from the narratives that rely on this incorrect usage. They can be kept on as disposable narratives, no more special than alternative narratives that match observations and experiments.


  From wikepedia Occam's razor In practice, the application of the principle often shifts the burden of proof in a discussion.[a] The razor states that one should proceed to simpler theories until simplicity can be traded for greater explanatory power. The simplest available theory need not be most accurate. Philosophers point out also that the exact meaning of simplest may be nuanced.

Assertion 2 - The usage of Occam's razor in science is pernicious - ie. Scientists who propogate a narrative or engage in research will deny that it relies on a shifting of the burden of proof. They will deny that science is biased against narratives and research that takes opposing razors. They will, however imply that opposing razors require proof, which they will freely accept if presented, while ignoring the unprovability of the razors, and ignoring the possibility that the consensus razor may have been simplified to something that is in fact impossible.

Occam's razor is involved in the following assertions being protected from the burden of proof:

1) Random mutations and natural selection is necessary and sufficient to explain the origin of species from other species.

2) Abiogenesis occurred on Earth, or an earth like planet.

3) Abiogenesis was the origin of life on Earth, rather than biotic life being designed by a completely different life form, which could have formed through abiogenesis, in a more provable way , and with intermediate forms.

4) Comets are pristine and relatively unchanged from when they were formed in a molecular cloud.

5) Comets originate from the Oort Cloud.

6) Randomly occurring non-gravitational forces and close planetary fly-bies account for the evolution of cometary orbits from semi-stable orbit eg. Kepler, eventually to other semi-stable orbits, eg. Sun grazer.

7) Natural non living processes account for the observed features of comets, even though, in the main, the observed features were substantially different to that predicted before observation.

Though the presence of a sentient cloud of gas may seem unlikely, the story is grounded in hard science

http://en.wikipedia.org/wiki/The_Black_Cloud

My assertion is that there is sentient life in forms completely different to life on Earth, in a similar way to the black cloud, that had a hand in the design of life as we know it. The only reason scientists stick to the assertion that life started from non-life with random natural processes is purely because of Occam's razor. Asserting forms of life we have not seen, nor have any direct evidence for, is generating more entities that need explanation, and also plays into the hands of Intelligent Design. However, what is wrong in believing in intelligent design where the designer evolved through natural processes not involving magic? It seems to me to expain why there is so little evidence of abiogenesis, better than the explanation starting from Darwin, that life is so superior to its predecessors that all evidence has been absorbed into life. Abiogenesis appears to be a singularity in the fossil record. Generally, that should always imply that life transferred from somewhere else, rather than evolving here to that stage, much like when a species is found in a particular geographic location without obvious precedents in that location.

In a letter to Joseph Dalton Hooker on February 1, 1871,[9] Charles Darwin addressed the question, suggesting that the original spark of life may have begun in a "warm little pond, with all sorts of ammonia and phosphoric salts, lights, heat, electricity, etc. present, so that a protein compound was chemically formed ready to undergo still more complex changes". He went on to explain that "at the present day such matter would be instantly devoured or absorbed, which would not have been the case before living creatures were formed."[10] In other words, the presence of life itself makes the search for the origin of life dependent on the sterile conditions of the laboratory.

From this, it appears prebiotic evolution has been imbued with particular properties that do not exist with postbiotic evolution. ie. that intermediate forms are destroyed. I find that intermediate forms being hypothesised without any evidence of them existing, with a "just so" story, such as Darwin's as being completely unscientific.

A hypothesis with no evidence has a vanishingly small probability of being correct.

If we were looking for life on other bodies, one of the techniques suggested is to look at the night side and see if there is light.

This has mainly been put forward looking at planets. However, I don't see why we shouldn't apply the same argument to asteroids and comets. The only comet that has been photographed up close while in its active state, appears to have emissions emanating from both the sun side and the other side.

Not much has been mentioned about discrete jets, but although ostensibly powered by direct solar radiation, the jets on comets are not a predictable function of solar radiation. There appears to be jets emanating light as well as matter, from looking at the night side of the comet. This could be the reflective emissions when they get past the shadow, but it is plausible that radiation is also emanating.

Non-gravitational forces on comets are quite substantial, and the biggest in magnitude are due to rotation of the comet and are heavily dependent on the shape of the comet. In turn the rotation of the comet is influenced by the jets. Thus a fairly small amount of energy from the jets, can give a non-gravitational force many orders of magnitude greater than what a jet could. Also, the topography of comets, unlike asteroids, are not determined by impact craters, but are also apparently determined by internal forces, probably jets. Thus both the rotation and shape, thus total thrust is potentially determined by jet emissions.

NASA mission OSIRIS-REX - Mission to go to an "asteroid". This is classed as a caronaceous and has very low Albedo. It may have a lot of properties similar to comets, and thus possibly jets, outgassing, etc. Dependig on the results in 2014 of ROSETTA, it may add some information about whether there is life on comets.

Conclusion: biotic life was designed in comets' image, by comets.
