“Comets are literally out of this world. As the flood began, the extreme pressure in the interconnected subterranean chambers and the power of supercritical water exploding into the vacuum of space launched about 50,000 comets, totaling less than 1% of the water in the chambers.” –Dr. Walter Brown, Creationist
“Scientists were stunned to find a huge range of minerals in the particles captured by NASA’s Stardust probe as it swooped past the comet Wild 2 on 2 January 2004. Many of the compounds could only have formed close to a star [Ed. like deep under the surface of the earth?]— far from the chilly outskirts of the Solar System where the comet first coalesced.” –Nature 440, 260 (16 March 2006) (See below)
Dr. Walter Brown is somewhat of a contrarian creationist … that is, he doesn’t subscribe to the ICR/AIG theory of the Flood of Noah, which currently is Dr. John Baumgardner’s Catastrophic Plate Tectonics (CPT). He has his own theory called the Hydroplate Theory and the parts I’ve studied seem to make a lot of sense, including his comet theory, given this new “stunning” information about high temperature minerals in comets. You can read an overview of his theory online HERE. One interesting part of his theory is his belief that comets originated in the “Fountains of the Deep” (Genesis 7:11), contra to the mainstream view of the Oort Cloud Theory. Here’s a summary of his view …
Hydroplate Theory. Comets are literally out of this world. As the flood began, the extreme pressure in the interconnected subterranean chambers and the power of supercritical water exploding into the vacuum of space launched about 50,000 comets, totaling less than 1% of the water in the chambers. (These numbers will be derived later.) This water was rich in heavy hydrogen. As subterranean water escaped, the chambers’ pillars were crushed and broken. Also, the 10-mile-high walls along the rupture were unstable, because granitic rock is not strong enough to support a cliff greater than 5 miles high. The bottom portions of the walls were crushed into large blocks which were swept up and launched by the fountains of the great deep. Carried up with the water were eroded dirt particles, pulverized organic matter (especially cellulose from preflood forests), and even bacteria.
Droplets in this muddy mixture froze quickly in outer space. The expanding spheres of influence of the larger rocks captured more and more ice particles which later merged gravitationally to form comets. Some comets and rocks hit the near side of the Moon directly and formed large basins. Those impacts produced lava flows and debris which then caused secondary impacts. Water vapor condensed in the permanent shadows of the Moon’s polar craters.
Hyperbolic comets never returned to the solar system. Near-parabolic comets now being detected are returning to the inner solar system for the first time. Comets launched with slower velocities received most of their orbital velocity from Earth’s orbital motion. They are short-period comets with elliptical, prograde orbits lying near the Earth’s orbital plane. Since the flood, many short-period comets have been pulled gravitationally into Jupiter’s family. Comets launched with the least velocity are small comets. [For a more complete description of the hydroplate theory, see pages 102–135.]
Now look what they found recently in some comets …

Comet chasers get mineral shock

Stardust mission yields unexpected bounty.
The first results from a mission to catch dust from a comet’s tail have revealed a surprise: these balls of dirty snow are born of fire as well as ice. Scientists were stunned to find a huge range of minerals in the particles captured by NASA’s Stardust probe as it swooped past the comet Wild 2 on 2 January 2004. Many of the compounds could only have formed close to a star — far from the chilly outskirts of the Solar System where the comet first coalesced.
And here’s another article …
NASA’s Stardust Comet Samples Contain Minerals Born in Fire

Pieces of a comet returned to Earth by NASA’s Stardust spacecraft apparently formed near the Sun or around another star altogether before being flung to the outer edges of the Solar System, mission scientists said Monday.
Researchers studying samples of Comet Wild 2 (pronounced “Vilt 2″) embedded in Stardust’s gel-filled collector found that the minerals formed under extremely high temperatures – such as those near a star – and not in the frigid cold expected at the Solar System’s edge, where most short-term comets originate.
“In the coldest part of the solar system we’ve found samples that formed at extremely high temperatures,” said Donald Brownlee, Stardust’s principal investigator at the University of Washington in Seattle, during a Monday press conference. “When these minerals formed they were either red hot or white hot grains, and yet they were collected in a comet, the Siberia of the Solar System.”
The finding – announced on the 20th anniversary of the European probe Giotto’s rendezvous with Comet Halley in 1986 – perplexed Stardust researchers and added a new wrinkle in astronomers’ understanding of how comets, and possibly the Solar System, formed.
Why were these researchers so stunned and perplexed? Well … because this finding does not fit their idea of how the solar system formed? Comets supposedly originated in the Kuiper Belt and in the Oort Cloud and these regions are very COLD. Could we say it’s a failed prediction of their model of solar system evolution? Hmmm …
If these researchers had read Walt Brown’s Hydroplate Theory, they would not have been so stunned and perplexed because they would have known that comets quite possibly could have come from somewhere near the Sun — EARTH!!
You might be amazed at how well his theory explains a whole host of phenomena including the Lunar Maria, the Mid Oceanic Ridge, Meteors and Asteroids and the Geologic Record. Of course, his theory is not perfect and there are some difficulties … but isn’t that true of ALL theories? The old theory of comet formation being a beautiful case in point.
