(my emphasis added)
Is this the ATM idea you intend to present?
In any case, would you mind presenting the logic in a little more detail?
Specifically, how were you able to rule out every other possible explanation (than "electrical discharge phenomena")? Including all the possible explanations that have not yet been invented? |
One very ATM idea, as something
yet to be invented, is that comets ala asteroids (with very eccentric orbits) are ‘dust collectors’ in the outer regions of our solar system, Kuiper Belt to Oort Cloud regions, which gather up material thrown off from the Sun’s solar wind. This could explain, with or without ‘electrical phenomena’, why the material thrown off by comet comas is
not predominantly water trails but show evidence of materials formed inside the Sun. However, and this would be truly ATM, it would necessitate a mechanism why such materials compact onto a comet very far from the Sun, while releasing or decompacting such material closer into the Sun. Solar heating may not be enough, especially since such comet tails show up already as far as Jupiter, which is far out there at 5 AU in a still cold region of space. Now the really really ATM explanation, as a hypothesis unsupported by any presently acceptable mainstream cosmology, would be if gravity (ala
Toivo Jaakkola,
Brans-Dicke,
Pioneer Anomaly gang, et al, even Milgrom's
MOND) is NOT a universal constant as now believed, but for reasons we do not yet understand it grows in its Newton G
density with greater distance from the Sun.
This strange hypothesis would handily explain why comets gather up dust far out there, but release it as they ‘decompact’ closer into the Sun where this G is much lower. If this were so, the explanation (perhaps in addition to the ‘electrical discharge’ idea), might handily put to bed why comets can be just like asteroids in composition but act so differently in their highly eccentric orbits (though not always) by casting off coma tails. However, before you lay into me to prove this theory and defend it energetically, I only post this here as a possible “let’s suppose” idea without further support or argument, though in the past I had devoted quite a bit of effort into explaining this (without any success whatsoever!
) on these ATM boards. So I leave it here as a “let’s suppose” idea only, without prejudice. So comets do not have to by “icy” at all, if this were found to be true, and could be entirely made up of ‘space dirt’ only.
[BTW, I did present a mini version of this idea in the “Discussion” section of Wiki page on Pioneer, as aka Ivan D. Alexander:
“ANOMALOUS ACCELERATION OF PIONEERS 10 AND 11 may be modeled on a gravitational delta effect, per the Equivalence Principle” – FYI]
