Velikovsky Correct About Pole Shift

"Diogenes Laertius repeated the teaching of Leucippus: 'The earth bent or inclined towards the south because the northern regions grew rigid and inflexible by the snowy and cold weather which ensued thereon.' The same idea is found in Plutarch, who quoted the teaching of Democritus: 'The northern regions were ill temperate, but the southern were well; whereby the latter becoming fruitful, waxed greater, and by an overweight preponderated and inclined to the whole that way.' Empedocles, quoted by Plutarch, taught that the north was bent from its former position, whereupon the northern regions were elevated and the southern depressed. Anaxagoras taught that the pole received a turn and that the world became inclined toward the south." -- Immanuel Velikovsky, cosmologist, 1950

"The sea erupted. Often the sea and land changed places. The immutability of contours of continents and seas, a dogma in geology, has no basis in fact. And immediately there is the problem of the climate. There were ancient climates that were very different from what they are today. If those corals grew where they were found, certainly the Earth was not travelling with the same elements of rotation and revolution which means not in the same orbit, not with the axis directed in the same position as it is today. If you don't believe it, try to cultivate corals on the North Pole." -- Immanuel Velikovsky, cosmologist, 1966

Stephen Smith: Europa's Unsettled Poles.

It appears as if the north and south poles on Jupiter's giant moon are no longer located where they originated.

Scientists have been studying images returned by the Galileo spacecraft for almost ten years now. The images transmitted from Jupiter's moons, in particular, revealed structures that seem to defy conventional geological theories. Why is Callisto covered with craters? Why does Ganymede possess a magnetic field? Why does Europa appear to be covered with water ice that is floating on a vast ocean?

A May 15, 2008 article in the science journal Nature announced that Europa seems to have experienced displacement of its north and south poles on more than one occasion.

Phil Plait: Censorship = Science

I've been banned from posting comments on the aptly named censorship advocacy website Bad Astronomy. Phil Plait had no logical or scientific response to my questions so rather than attempt to answer them persuasively he just deleted the questions. How scientific of him. Then he called me a troll because anyone who asks questions (Socrates etc) is a "troll". Not only did he delete my questions and prevent me from commenting but he also banned my ip from accessing the website. I wonder how much further science would have progressed by now if instead of directing their time and energy towards censorship they directed it towards listening, debating, and learning. If it wasn't for people like him I would probably have doubts about my beliefs. So let's all thank Phil for reinforcing our worldview.

I'm used to it by now. Brian R. has also banned me from commenting on Clastic Detritus.

UPDATE: He must've seen this because I can now access the website.

A Giant Breach in Earth's Magnetic Field

NASA: A Giant Breach in Earth's Magnetic Field. (Hat tip: BF)

Dec. 16, 2008: NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to exist. Solar wind can flow in through the opening to "load up" the magnetosphere for powerful geomagnetic storms. But the breach itself is not the biggest surprise. Researchers are even more amazed at the strange and unexpected way it forms, overturning long-held ideas of space physics.

"At first I didn't believe it," says THEMIS project scientist David Sibeck of the Goddard Space Flight Center. "This finding fundamentally alters our understanding of the solar wind-magnetosphere interaction."

The magnetosphere is a bubble of magnetism that surrounds Earth and protects us from solar wind. Exploring the bubble is a key goal of the THEMIS mission, launched in February 2007. The big discovery came on June 3, 2007, when the five probes serendipitously flew through the breach just as it was opening. Onboard sensors recorded a torrent of solar wind particles streaming into the magnetosphere, signaling an event of unexpected size and importance.

"The opening was huge—four times wider than Earth itself," says Wenhui Li, a space physicist at the University of New Hampshire who has been analyzing the data. Li's colleague Jimmy Raeder, also of New Hampshire, says "1027 particles per second were flowing into the magnetosphere—that's a 1 followed by 27 zeros. This kind of influx is an order of magnitude greater than what we thought was possible."

The event began with little warning when a gentle gust of solar wind delivered a bundle of magnetic fields from the Sun to Earth. Like an octopus wrapping its tentacles around a big clam, solar magnetic fields draped themselves around the magnetosphere and cracked it open. The cracking was accomplished by means of a process called "magnetic reconnection." High above Earth's poles, solar and terrestrial magnetic fields linked up (reconnected) to form conduits for solar wind. Conduits over the Arctic and Antarctic quickly expanded; within minutes they overlapped over Earth's equator to create the biggest magnetic breach ever recorded by Earth-orbiting spacecraft.

The size of the breach took researchers by surprise. "We've seen things like this before," says Raeder, "but never on such a large scale. The entire day-side of the magnetosphere was open to the solar wind."

The circumstances were even more surprising. Space physicists have long believed that holes in Earth's magnetosphere open only in response to solar magnetic fields that point south. The great breach of June 2007, however, opened in response to a solar magnetic field that pointed north.

"To the lay person, this may sound like a quibble, but to a space physicist, it is almost seismic," says Sibeck. "When I tell my colleagues, most react with skepticism, as if I'm trying to convince them that the sun rises in the west."

Velikovsky was well familiar with how difficult it was trying to tell people Herodotos and Plato were right about the sun rising in the West.

Here is why they can't believe their ears: The solar wind presses against Earth's magnetosphere almost directly above the equator where our planet's magnetic field points north. Suppose a bundle of solar magnetism comes along, and it points north, too. The two fields should reinforce one another, strengthening Earth's magnetic defenses and slamming the door shut on the solar wind. In the language of space physics, a north-pointing solar magnetic field is called a "northern IMF" and it is synonymous with shields up!

"So, you can imagine our surprise when a northern IMF came along and shields went down instead," says Sibeck. "This completely overturns our understanding of things."

Northern IMF events don't actually trigger geomagnetic storms, notes Raeder, but they do set the stage for storms by loading the magnetosphere with plasma. A loaded magnetosphere is primed for auroras, power outages, and other disturbances that can result when, say, a CME (coronal mass ejection) hits.

The years ahead could be especially lively. Raeder explains: "We're entering Solar Cycle 24. For reasons not fully understood, CMEs in even-numbered solar cycles (like 24) tend to hit Earth with a leading edge that is magnetized north. Such a CME should open a breach and load the magnetosphere with plasma just before the storm gets underway. It's the perfect sequence for a really big event."

Sibeck agrees. "This could result in stronger geomagnetic storms than we have seen in many years."

Scientists Confirm Infinite Hydrocarbons On Titan

Some Cassini scientists indicate that such volcanism could release methane from Titan's interior, which explains Titan's seemingly continuous supply of fresh methane. Without replenishment, scientists say, Titan's original atmospheric methane should have been exhausted long ago.

Stream of Atomic Hydrogen Coming From The Sun

James Anthony Phillips: Solar Flare Surprise.

Dec. 15, 2008: Solar flares are the most powerful explosions in the solar system. Packing a punch equal to a hundred million hydrogen bombs, they obliterate everything in their immediate vicinity. Not a single atom should remain intact.

At least that's how it's supposed to work.

"We've detected a stream of perfectly intact hydrogen atoms shooting out of an X-class solar flare," says Richard Mewaldt of Caltech. "What a surprise! These atoms could be telling us something new about what happens inside flares."

The event occurred on Dec. 5, 2006. A large sunspot rounded the sun's eastern limb and with little warning it exploded. On the "Richter scale" of flares, which ranks X1 as a big event, the blast registered X9, making it one of the strongest flares of the past 30 years.

NASA managers braced themselves. Such a ferocious blast usually produces a blizzard of high-energy particles dangerous to both satellites and astronauts. Indeed, moments after the explosion, radio emissions from a shock wave in the sun's atmosphere signaled that a swarm of particles was on its way.

An hour later they arrived. But they were not the particles researchers expected.

NASA's twin STEREO spacecraft made the discovery: "It was a burst of hydrogen atoms," says Mewaldt. "No other elements were present, not even helium (the sun's second most abundant atomic species). Pure hydrogen streamed past the spacecraft for a full 90 minutes."

Gravity In The Garbage Can

Science Daily: Planet Formation Could Lie In Stellar Storms Rather Than Gravitational Instability.

ScienceDaily (Dec. 15, 2008) — New research suggests that turbulence plays a critical role in creating ripe conditions for the birth of planets. The study, to be published in The Astrophysical Journal, challenges the prevailing theory of planet formation.

Using three-dimensional simulations of the dust and gas that orbits young stars, the study demonstrates that turbulence is a significant obstacle to gravitational instability, the process that scientists have used since the 1970s to explain the early stage of planet formation.

Gravitational instability proposes that dust will settle into the middle of the protoplanetary disk around a newly-formed star. It is thought that the dust will gradually become denser and thinner until it reaches a critical point and collapses into kilometer-size clumps, which later collide to form planets. But new research by San Francisco State University professor Joseph Barranco shows that turbulent forces keep the dust and gas swirling and prevent it from forming a dense and thin enough layer for gravitational instability to occur.

"These results defy the proposed solution of how planets are formed," Barranco said. "Scientists have long been using gravitational instability theory to explain how millimeter-size particles grow to kilometer-size, but these new simulations open new avenues of investigation. Perhaps massive storms, similar to hurricanes found on the Earth or Jupiter, provide clues about how tiny dust grains clump together to become kilometer-size boulders."

Hmmm. Planets forming from the hurricanes of Jupiter? I seem to remember a certain Dr. Velikovsky making such a claim.

Warm Plasma Cloak Discovered

Science Daily: Discovery Of Warm Plasma Cloak Surrounding Earth, New Region Of Magnetosphere

ScienceDaily (Dec. 14, 2008) — A detailed analysis of the measurements of five different satellites has revealed the existence of the warm plasma cloak, a new region of the magnetosphere, which is the invisible shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind.

The study was conducted by a team of scientists headed by Charles "Rick" Chappell, research professor of physics and director of the Dyer Observatory at Vanderbilt University and published this fall in the space physics section of the Journal of Geophysical Research. The northern and southern polar lights – aurora borealis and aurora australis – are the only parts of the magnetosphere that are visible, but it is a critical part of Earth's space environment.

"Although it is invisible, the magnetosphere has an impact on our everyday lives," Chappell said. "For example, solar storms agitate the magnetosphere in ways that can induce power surges in the electrical grid that trigger black outs, interfere with radio transmissions and mess up GPS signals. Charged particles in the magnetosphere can also damage the electronics in satellites and affect the temperature and motion of the upper atmosphere."

The other regions of the magnetosphere have been known for some time. Chappell and his colleagues pieced together a "natural cycle of energization" that accelerates the low-energy ions that originate from Earth's atmosphere up to the higher energy levels characteristic of the different regions in the magnetosphere. This brought the existence of the new region into focus.

The warm plasma cloak is a tenuous region that starts on the night side of the planet and wraps around the dayside but then gradually fades away on the afternoon side. As a result, it only reaches about three-quarters of the way around the planet. It is fed by low-energy charged particles that are lifted into space over Earth's poles, carried behind the Earth in its magnetic tail but then jerked around 180 degrees by a kink in the magnetic fields that boosts the particles back toward Earth in a region called the plasma sheet.

Chappell and his colleagues – Mathew M. Huddleston from Trevecca University, Tom Moore and Barbara Giles from the National Aeronautics and Space Administration, and Dominique Delcourt from the Centre d'etude des Environments Terrestre et Planetaires, Observatoire de Saint-Maur in France – used satellite observations to measure the properties of the ions in different locations in the magnetosphere.
