The
jet structure on comet Wild 2 is radically different
from what orthodox comet models anticipated. Such jets
pose no problem for the electrical model.
NASA's Stardust
spacecraft snapped these photos of Comet Wild 2 on
January 2, 2004. On the left is the comet nucleus and on
the right a composite of the nucleus and a longer
exposure highlighting the comet's jets. According to a
recent press release, project scientists expected "a
dirty, black, fluffy snowball" with a couple of jets
that would be "dispersed into a halo". Instead they
found more than two dozen jets that "remained
intact"-they did not disperse in the fashion of a gas in
a vacuum. Some of the jets emanated from the dark
unheated side of the comet-an anomaly no one had
expected. Chunks of the comet, some as big as bullets,
blasted the spacecraft as it crossed three jets. Wild
2's surface was covered with "spires, pits and craters"
that could only be supported by rock, not by
sublimating ice or snow. The discovery was more than
surprising, "it was mind-boggling".
When a theory's
predictions are constantly discredited by new
discoveries, it is "falsified". The unexpected blast of
particles hitting Stardust is one small ding for the
spacecraft's shield, but the Wild 2 anomalies are one
giant fender-bender for the dirty snowball theory.
For many years
now, the theory itself has obstructed the view of
evidence, including close-up photographs of comets and
asteroids. The NASA press release claims the comet "is
unlike any other type of solar system body". Unlike
Comet Borrelly, which sported unexpected "mountains,
faults and grooves"? Unlike comet Halley, with its hot
jets and diverse landscape? Unlike the steep-edged and
flat-bottomed craters on asteroids Eros and Mathilda and
Ida? Unlike the scarred surface of the Martian moon
Phobos, virtually all the Jovian moons (especially the
little ones), and now Saturn's little moon Phoebe? Every
small solid body we've approached has surprised
scientists with such sharply-defined surface relief.
The cascade of
discovery has not surprised scientists investigating
electrified plasma in space. But astronomers and
astrophysicists are unaware of this century-old field of
study. The structural details of the craters, grooves,
cliffs, and other landforms, as well as the collimated
jets, match those produced in plasma labs.
In the electrical
hypothesis, a rock moving rapidly through the
electric field of the Sun will develop a plasma sheath
that stretches into a coma thousands of kilometers
across and a filamentary tail that remains coherent over
millions of kilometers. Arcing to the surface will
generate high temperatures in small areas. The
electrical activity will produce X-rays and ultraviolet
light. The predictions of the model are testable, and
the implications reach far beyond modern comet theory.
