I will start collecting the evidence against the electric comet idea in one post. This will be updated as we discuss the many problems with the EC idea.
EC universe: Ignore the physical evidence such as the measured density of comets.
Real universe: Use the physical evidence such as the measured density of comets to construct theories.
EC universe: Comets are rocks.
Real universe:
- Comets have meaured densities that are much less than that of rocks (asteroids).
- Comets may not have the composition of asteriods
- Deep Impact confirmed that comet nuclei are made of dust and ice not rock. There were a couple of surprises in that the dust was talcum powder rather than sand and the amount of ice was smaller than expected.
"Analysis of data from the Swift X-ray telescope showed that the comet continued outgassing from the impact for 13 days, with a peak five days after impact. A total of 5 million kilograms (11 million pounds) of water[35] and between 10 and 25 million kilograms (22 and 55 million pounds) of dust were lost from the impact."WP
EC universe: Comet coma and tails are created from material that that is created from rock by
electrical discharge machining.
Real universe:
Start with Tim Thompson's posts about this
EC universe: Rocky bodies that have an orbit with an eccentricity above a minimum value will be comets.
N.B. Solar activity may cut tails in two but there have been no observations of comets turning off during low solar activity.
(Sol88: I may be wrong - if so please provide the citations to these marvelous events.)
However this assertion has the fatal flaw of EC predictions - no mathematics or numbers.
But we can do their work for them can't we Sol88?
There are 4 observed
main-belt comets with a minimum eccentricity of 0.1644 (
133P/Elst-Pizarro). So the EC minimim must be this (or lower!).
Real universe: There are rocky bodies that have an orbit with an eccentricity above a minimum value that are
not comets.
In fact there are asteroids in orbits that are get close to cometary orbits, e.g.
2005 VX3 with an eccentricity of 0.9955142)
The
JPL Small-Body Database Browser has a
search engine. This shows that there are 173,583 cataloged asteroids with an eccentricity > 0.17.
EC universe: Only give qualitative predictions.
Sol88 posted a
list of EC "predictions" for Tempel 1 and Deep Impact. The closes it gets to an actual quantitative predictions is "The most obvious would be a flash (lightning-like discharge) shortly
before impact." (emphasis added).
What actually happened was a flash
on or after impact followed by a bigger one from deeper in the nucleus.
Real universe: Scientific theories model the data mathematically and produce both qualitative and quantitative predictions.
Someone could start with the papers of Whipple
- Whipple, Fred L. (1950). "A Comet Model. I. The acceleration of Comet Encke". Astrophys. J. 111: 375–394. doi:10.1086/145272. http://adsabs.harvard.edu//full/seri/ApJ../0111//0000375.000.html.
- Whipple, Fred L. (1951). "A Comet Model. II. Physical Relations for Comets and Meteors". Astrophys. J. 113: 464. doi:10.1086/145416. http://adsabs.harvard.edu//full/seri/ApJ../0113//0000464.000.html.
- Whipple, Fred L. (1955). "A Comet Model. III. The Zodiacal Light". Astrophys. J. 121: 750. doi:10.1086/146040. http://adsabs.harvard.edu//full/seri/ApJ../0121//0000750.000.html.
and then go ointo the 1000's of scientific papers and many textbooks about comets. Tim Thompson recommened
Introduction to Comets by Brandt & Chapman (Cambridge University Press, 2004, 2nd edition).
EC universe: Turn yourself into a crackpot idea by not publishing papers in peer reviewed journals.
Real universe: Take the risk being wrong and become part of the scientific process by publishing papers in peer reviewed journals, e.g. Fred L. Whipple.
