Is Venus’ Rotation Slowing Down?

Using the VIRTIS infrared instrument, scientists discovered that some surface features were displaced by up to 20 km from where they should be given the accepted rotation rate as measured by the Magellan orbiter in the early 1990s.
Over its four-year mission, Magellan determined the length of the day on Venus as being equal to 243.0185 Earth days. But the data from Venus Express indicate the length of the Venus day is on average 6.5 minutes longer.
What could cause the planet to slow down? One possibility may be the raging weather on Venus. Recent atmospheric models have shown that the planet could have weather cycles stretching over decades, which could lead to equally long-term changes in the rotation period. The most important of those forces is due to the dense atmosphere – more than 90 times the pressure of Earth’s and high-speed weather systems, which are believed to change the planet’s rotation rate through friction with the surface.
Earth experiences a similar effect, where it is largely caused by wind and tides. The length of an Earth day can change by roughly a millisecond and depends seasonally with wind patterns and temperatures over the course of a year.
But a change of 6.5 minutes over a little more than a decade is a huge variation.

Saw the documentary on H2 ( History International ) channel yesterday.
Definitely worth watching. On the Winter solstice circa Dec, 21, 2012,
the Earth will be entering the New Age # 6, as the Sun rises in conjunction
with the center of the Galactic core where a supermassive black hole is
located. Venus is supposed to pass in front of the Sun in an eclipse which
is a somewhat rare occassion that per se happens only once every 100
years. The ancient Mayans ostensibly developed their cosmic clock cal
culations because they were visited by E.T.s long before who geneticly engineered. them to mine Gold for their ships. Otherwise they were brutal savages making bloody human sacrifices as the Aztecs did. But due to the
E.T.'s influence the Mayan kings saw themselves as masters of time and
space itself. They had a lot of cohones after their E.T. visitations. They
ventured many many leagues in open boats to a small island in the South
Pacific, where their king had a large labor force carve a monument out
of the volcanic rock ledge which was several hundred feet high.From this one spot only on all the earth, they were told they could watch
the Venus eclipse at the reset of their cosmic clock in the next Age which
happens only on one day in many thousands of years. Venus, and all
the other planets in our solar system were believed to be Gods to the
ancient Mayans. Venus was their highest God. And whenever Venus
had a special transit with the Sun, it was considered a spiritual experience
they had with their Gods, and with their dead ancestors. One Historical
fact is that during the beginning of the last Mayan Age, the influence
of the black hole's emission of gamma radiation bursts made extinct
hundreds of animal species, caused widespread sizemic disruptions
in erupting volcanos, and earthquakes. But the interesting fact of that
last occurrence was that it happened on the Summer Solstice. Supposedly,
it has the opposite effect of destruction alternating between the Solstices.
The H2 documentary is called Apocalypse Island. And it IS fascinating. - 4 months ago

The documentary claimed that only 4 of the ancient Mayan's books survive
to this day because the Christian missionaries had such an overreaction to
seeing their blood sacrifices that they wanted to repress any recorded
materials associated with their cultural traditions. They likened it to future
modern people visiting New York City after an Apocolypse had destroyed
all their libraries of stored books, and trying to envision what their culture
was like from only their engravings in granite, and stone. What a world.
It's true what they say though. That the ancient Peruvian landing strips
shaped like icons and carved out of solid rock, could have been seen
from space. The E.T.s must have been visiting the Mayans for a long
long time. Maybe they had the most advanced metal detector of all. The
E.T.s did the same thing in Eqypt when they enabled the ancient Eqyptians
to build the pyramids which were all deliberately oriented toward very
specific constellations. The pyramids themselves theorized to being
hydrogen fuel factories. And solid Gold artifacts of airplanes dating back
many thousands of years. These artifacts were computer scanned &
measured, then reproduced. They flew perfectly, being found to have
perfect aerodynamics not present on even the most modern human
only engineered aircraft. A A A A Aliens ! - 4 months ago

the Egyptians also traveled the planet...pyramids in China, underground cities in the Grand Canyon and Death Valley, and a tomb to a pharaohs son bitten by a snake in Australia.

OK I wanna see a link on information for this tomb in Australia. The underground cities in North America I will argue are not of Egyptian influence, I have been to many of them and the quality of the stonework is not even in the same realm as Egyptian artisanry. To give them credit for this takes much away from my native ancestors. The pyramids in China are more convincing, but again there is only one similarity between the chinese structures and those of egyptians and thats the overall shape of the structures, all the details and construction methods are quite different. I am however very curious about this Australian tomb.

Thank you, and I wouldn't have doubted it before but I will take this as evidence that they were traveling. However they were on an exploratory mission here, not one of apparent colonial or diplomatic intentions. It's highly interesting to see the script about their damaged "ship" harbored in shallows tied off by rope. This is a solid piece of evidence actually against the "egyptians were technologically superior even to modern people". If these people were capable of flight why would the son of the Pharoah be made to travel by sail and foot if the supposed tech was actually available? I would love full photos of the engraved walls to allow for translation through multiple sources just to be certain of what they say.
So ya, the Egyptians at least passed through NW coastal Queensland, which I am thinking would be FAR more the case with the North American or Chinese connections as well, trade of resources and ideas or perhaps artifacts but not actually colonization in locales that they could not support or defend so far from their "motherland".
--Edit--Additionally have you read the news lately that it would seem our native american peoples are actually the decendants of early oriental people. The similarities to Tibetan religious traditions are strong in this case as well.

http://www.newscientist.com/article/dn11178-native-american-populations-share-ge...This site could just as likely (if not more so) be he only remains of the supposedly siberian culture that was imported here during their migration to North America... I would try to see and reconcile this with evidence of ancient homesteading along the Pacific Coast and foothills of the Rockies. Because of this information I am already researching what I can about Native American origins myths and those of the Tibet/Siberian region of Asia to see what similarities and glaring inconsistancies they may have.

OK again on the Grand Canyon links you gave I have to point out that the one focusing on the "Smithsonian Conspiracy" is extremely biased both idealogically and politically, despite presenting decently strong arguements in favor they fail to provide ANY evidence of the Grand Canyon claim. The second site, philipcoppens is much more unbiased and factually oriented. However a link presenting evidence of people who "know" where the archeological site is then intimation that he had never actually been there doesn't bode well for either arguement for or against. However I did find one sentence from the original news article that would make it obvious to anyone with a strong understanding of Egyptian Heiroglyphs that the markings reportedly discovered ARE NOT of Egyptian heritage.
"The engraving on the tables probably has something to do with the religion of the people. Similar hieroglyphics have been found in southern Arizona. Among the pictorial writings, only two animals are found." Similar markings in Arizona (Pueblo, Cherokee, Anasazi and many others) would indicate a native language, especially considering that among the writings only TWO animals were found. Even the simple naming convention of the ancient Egyptians would lead to the use of FAR more then just two animal figures in their scripts. There is no photographic evidence of these glyphs, but I know that the native languages that have some script associated with them are more geometric(squares, sun circles, spirals) or whimsical (forms of waves or "wind gusts") and do not include nearly as many animal patterns as their Egyptian counterpart. Again I stand by my thoughts these locations in NA are remnants of our native cultures, of course with the open mind that they may have been constructed at the suggestion of visitors from the Nile delta, but not actually BY them.
P.S. as far the park rangers and access to a site are concerned, have you never gone someplace you weren't supposed to go? Its not as if huge swathes of the canyon are roped off or held under armed guard. Grab your supplies and a good local guide and you can go anywhere in the region that you want to...except for the inner workings of the Hoover Dam, that does have armed guards.

The pyramid debate will rage on until we have evidence. My arguement here is that the pyramid is one of the most simple and strongest geometric structure. The first person to build a trussed(angled) roof knew the inherent strength of the rectangle and this left only one square structure away from understand the logevity and strength of four triangles joined at the edge. The argument about "How would they know that a pyramid made of stone would last forever?" is rediculous at the most base of levels. A rectangular structure with a flat roof will collapse much faser and under much less stress then one with an angled roof, and a roof that angles up from all four sides is that much stronger. The pyramid cannot be viewed as a strictly "egyptian invention". This is like saying the Sumarians invented the circle because they were the first to depict circles in their art and therefor every circle you see before the convention of mathematics and geometry were put there by the Sumarians.

true, but pyramids can be found on every continent...I even found one on Antarctica looking at google earth that when I went back to share the spot I had marked a few months later was blurred and covered by a CGI image...it is my thought after a great deal of research in many directions that after the sinking of Atlantis the high priests spread to many corners of the world and took what knowledge they had with them. That is why we see crude antiquities right next to unexplainable tech and understanding that these cultures should not have had. Drastic advances came to many civilizations around the exact same time and I no longer believe in coincidence.
There has been a purposeful destruction of history and much of the speculation on what has been discovered is cataloged as conspiracy and bunk.

Very large skulls attached to mummified remains is what I read, but yeah there is much to relearn. But the pyramid connection I am very dubious of because of the simplicity of the structure and the MANY ways that humans could be persuaded to try a structure of the type... play with sand you will eventually make a pyramidlike shape, freestanding and made of nothing buyt loose sand... stare at a mountain long enough and the shape of a pyramid becomes apparent and we have long sought to simulate the strengths we witness in nature.
Yes, the deplorable loss of knowledge is a tale as old as mankind itself, and should never happen the way it has, however making connections between two points of interest need to be done so with the utmost respect for the evidence at hand.

That would make sense if it's rotating in the dexter ( right to left ) direction
compared to the sinister ( left to right ) direction. Maybe it has more Feng Shui

Only backwards.....
http://www.astronomycafe.net/qadir/q50.html
Why does Venus rotate backwards from the other planets?
The rotation period of Venus cannot be decided through telescopic observations of its surface markings because its featureless thick atmosphere makes this impossible. In the 1960's, radar pulses were bounced off of Venus while at its closest distance to the Earth, and it was discovered that its rotation period, its day, was 243.09 +/- 0.18 earth days long, but it rotated on its axis in a backwards or retrograde sense from the other planets. If you were to look down at the plane of the solar system from its 'north pole' you would see the planets orbiting the Sun counter clockwise, and rotating on their axis counterclockwise. Except for Venus. Venus would be rotating clockwise as it orbited the Sun counterclockwise.

hmm. I was not aware of that. Since all planets that coalesced from the same primordial material contain the same orbital momentum, there can only be a couple of answers.
A. Venus formed elsewhere and then was capture in solar orbit at a later date.
B. Venus was impacted at some point by another object large enough to spin it in another direction.
C. Something impacted Venus that was large enough to turn it upside down; flip the poles. - 4 months ago

I lean towards: A. Venus formed elsewhere and then was capture in solar orbit at a later date.
I'm a fan of the late great Immanuel Velikovsky and his Worlds In Collision theory.
He proposed that Venus was actually born from the Eye of Jupiter some 4,000 years ago as recorded in the legend of Aphrodite and Zeus, as well as countless myths worldwide.
The Mesoamerican deity Quetzalcoatl is strongly associated with this Venus event.
