Cometary Asteroids
*
May 18, 2011*
*In an Electric Universe, comets are thought to be rocks moving rapidly
through the Solar System's force fields.*
Comets are often called "dirty snowballs" by astronomers. However,
various investigative missions, such as Giotto and Deep Impact, revealed
them to be blackened, cratered, and fractured. No ice fields, reflective
crust, or watery clouds were observed. The Giotto spacecraft's _close
approach_ <http://neo.jpl.nasa.gov/images/halley2.jpg> to Halley's comet
discovered the blackest object ever seen. The comet's energetic plumes
blasted out from a dense nucleus.
Comet Tempel 1 resembled an asteroid more than a chunk of muddy slush.
Craters, boulders, and cliffs were observed—nothing like a snowball
venting. Water vapor was discovered near the comet, but there was too
little ice on the surface to account for it.
Other comets defy convention: Shoemaker-Levy 9 exploded when it
encountered Jupiter's magnetosphere, and the pieces did not expel the
volatile compounds astronomers expected to see. Deep Space 1 flew by
comet Borrelly in 2001, finding it hot and dry instead of cold and wet.
The Stardust mission to comet Wild 2 found a great deal of dust, but no
trace of water could be found on its surface.
Comets travel through a differential electric potential as they move
toward the Sun. The variable electric fields cause visible glow
discharges. Rather than "dirty snowballs" or even "snowy dirtballs,"
comets are electrically active, solid bodies.
Comets form plasma sheaths that can become comas, often more than a
million kilometers in diameter. Plasma filaments connect comets with the
Sun's electric field, generating "hot spots" on their surfaces. So hot
that extreme ultraviolet light and X-rays were detected radiating from
_comet Hyakutake_
<http://www.thunderbolts.info/tpod/2004/arch/040824comet-xrays.htm>.
According to a recent _press release_
<http://www.astronomynow.com/news/n1105/02asteroid/>, on December 11,
2010 asteroid 596 Scheila became much brighter than previously observed,
forming a large C-shaped coma. The _Swift_
<http://swift.gsfc.nasa.gov/docs/swift/swiftsc.html> space-based
observatory did not find water vapor thought to be "normally" associated
with comets. Instead, two dusty plume-like tails trailed behind the
asteroid, subsequently fading over the next several months.
A Hubble Space Telescope image of 596 Scheila reveals a broad coma,
along with a dust tail. As team leader David Jewett said: “The Hubble
data are most simply explained by the impact, at 11,000mph [17,700 km/h]
of a previously unknown asteroid about 100 feet [30 metres] in diameter.”
The primary reason for thinking that 596 Scheila is an asteroid and not
a comet is because there is no water vapor in its vicinity. The team
investigating the Deep Impact mission to comet Tempel 1 claimed that
there was "lots of ice" ejected when the copper projectile hit the
comet's surface, so it was expected that 596 Scheila would also have
lots of ice if it was a comet. However, Electric Universe advocate _Wal
Thornhil_ <http://www.holoscience.com/news.php?article=nm613913>l took
issue with that presumption just after Deep Impact:
"The flaw in the conventional approach is that only gas-phase chemical
reactions and reactions induced by solar radiation (photolysis) are
considered. The far more energetic molecular and atomic reactions due to
plasma discharge sputtering of an electrically charged comet nucleus are
not even contemplated...The hydroxyl radical, OH, is the most abundant
cometary radical...It is chiefly the presence of this radical that leads
to estimates of the amount of water ice sublimating from the comet nucleus.
"The electric field near the comet nucleus is expected if a comet is a
highly negatively charged body, relative to the solar wind...So the
presence of negative oxygen and other ions close to the comet nucleus is
to be expected. Negative oxygen ions will be accelerated away from the
comet in the cathode jets and combine with protons from the solar wind
to form the observed OH radical at some distance from the nucleus. The
important point is that the OH does not need to come from water ice on,
or in, the comet."
As mentioned in a _previous_
<http://www.thunderbolts.info/tpod/2009/arch09/091006centaurs.htm>
Picture of the Day, there are several "Centaur objects" orbiting near
the asteroid belt that demonstrate that indeterminate state between
comet and asteroid. 2060 Chiron is classified as both comet and
asteroid. Chiron manifests a coma whenever it reaches its closest
approach to the Sun, although it does not grow a tail. _174P Echeclus _
<http://observatory.ou.edu/>displayed a coma in 2005, so it too is now
classified as a cometary asteroid. At least ten Centaurs are known to
have cometary activity at great heliocentric distance.
Proponents of mainstream viewpoints are slowly beginning to realize that
asteroids and comets exist in a continuum: neither are strictly
identical nor completely different from the other. When the Stardust
mission returned to Earth with samples from the coma of comet Wild 2,
scientists found that the material looked more like meteoric dust than
what was expected from a dirty snowball.
Stardust also found that the coma of Wild 2 contained the "signature" of
water vapor, although the farther from the surface of the comet it was,
the greater the amount of vapor it saw. Whatever water or hydroxyl
compounds found in cometary comas are probably created there, as Wal
Thornhill has explained: ionized oxygen from the comet reacts with
hydrogen ions streaming out from the Sun. No "jets" of water vapor spew
from comets, and no icy plains have ever been observed. It is electric
effects that are seen. Discharges and arcs form the comet phenomena.
Exposing an asteroid to an intense electric field over time will most
likely create a comet.

* New DVD*
The Lightning-Scarred Planet Mars
A video documentary that could change everything you thought you knew
about ancient times and symbols. In this second episode of Symbols of an
Alien Sky, David Talbott takes the viewer on an odyssey across the
surface of Mars. Exploring feature after feature of the planet, he finds
that only electric arcs could produce the observed patterns. The high
resolution images reveal massive channels and gouges, great mounds, and
crater chains, none finding an explanation in traditional geology, but
all matching the scars from electric discharge experiments in the
laboratory. (Approximately 85 minutes)

Authors David Talbott and Wallace Thornhill introduce the reader to an
age of planetary instability and earthshaking electrical events in
ancient times. If their hypothesis is correct, it could not fail to
alter many paths of scientific investigation.
More info <http://www.mikamar.biz/book-info/tog-a.htm> Professor of
engineering Donald Scott systematically unravels the myths of the "Big
Bang" cosmology, and he does so without resorting to black holes, dark
matter, dark energy, neutron stars, magnetic "reconnection", or any
other fictions needed to prop up a failed theory.
More info <http://www.mikamar.biz/book-info/tes-a.htm> In language
designed for scientists and non-scientists alike, authors Wallace
Thornhill and David Talbott show that even the greatest surprises of the
space age are predictable patterns in an electric universe.
