What's Supposed to Happen in 2012?
Depending on who's
doing the prophesying, the winter solstice in the year 2012 could usher in a
day of celebration — or a day of chaos. December 21, 2012 has been marked as a
special day since the time of the Maya, whose calendar first touted it as the end
of a great 5,126 year cycle. Now, just a few years before the day of reckoning
is upon us, the human race is forced to consider the possibility of an
approaching apocalyptic nightmare. Only time will tell whether 2012 will be the
end, a new beginning, or just a year like any other.
THEORY:
The End of the Maya Calendar Cycle
This is where it all begins. The Maya Long Count calendar comes to the end of a 5,126 year cycle soon—possibly on December 21, 2012. The exact date is debated, as is what will happen when we hit that date. There is no record telling us exactly what the ancient Maya expected to happen when this cycle ended and the next began. But some think they would have been worried about the end of mankind as we know it.

THEORY: Bible Code Prophecy
At least one interpretation of the Bible tells us that in the year 2012, God will destroy Earth. With the help of computers, Israeli mathematicians have discovered a supposed secret code in the Bible's text. Michael Drosnin, author of The Bible Code, also decoded the text based on the mathematicians' work. According to Drosnin's interpretations, comets are due to rain down upon Earth in both 2010 and 2012.

THEORY: Terrence McKenna's Timewave Zero
In the early 1970s, Terence McKenna took a trip to the Amazon rainforest, where he experienced mind-bending drugs. Upon his return, he utilized the I Ching, the ancient Chinese book of divination, to determine a mathematical formula he called "timewave zero." According to his research, this formula predicts that time will form into tighter and tighter spirals until a "final time" is reached. When this happens, the laws of physics as we currently experience them will no longer apply, and the world will suddenly enter a new era with new, unknown laws. Originally set to occur on November 17, 2012, McKenna later moved the date when he determined the occurrence of the next galactic alignment: December 21, 2012.

THEORY: Nostradamus' Prophecies
The infamous seer's writings have been cited as predicting such historical events as the reign of Napoleon, the tyranny of Hitler, both World Wars, and September 11th. His writings also contain a number of end of the world prophecies which have yet to occur. His written quatrains prophesize everything from earthquakes and rampant disease to the coming of an antichrist and the onset of World War III. While not specifically pinpointed to the year 2012, many believe that Nostradamus' prophecies will coincide with the end of the Maya calendar.

THEORY: Rogue Planet Collision
Author Zecharia Sitchin wrote of a 5,000-year-old tale of planet Nibiru, home to a race of beings called the Annunaki, orbiting the sun beyond Pluto. Although dismissed by many as a myth, some believe that because of an unusual orbit, Nibiru is set to disrupt Earth in 2012. Recent science has indeed discovered a planetary body that is slightly larger than Pluto and three times farther from the sun, named Eris. Despite assurances from NASA that Eris is not headed anywhere near Earth, followers of Sitchin’s ideas fear that Eris is indeed Nibiru and will follow a rogue orbit, coming close enough to the solar system that its gravitational pull could dramatically alter the face of the Earth, wreaking unprecedented havoc on our gravity and electromagnetic fields.

THEORY: Galactic Alignment
In the galactic alignment, the winter solstice sun will line up perfectly with the galactic equator, an invisible line that denotes the center of the Milky Way galaxy. According to researcher John Major Jenkins, this precise alignment only occurs once every 26,000 years—and the next one is scheduled to take place by 2016. Jenkins asserts that rather than doomsday, the galactic alignment will bring about a shift in the human psyche toward a more conscious state.

THEORY: Solar Storms on Earth
Approximately every 11 years, the number of sunspots on our sun peaks at what we call a solar maximum. These sunspots, giant magnetic storms which appear as dark splotches on the sun's surface, release solar flares that vary in intensity. The next solar maximum is due to occur in 2012, and if powerful solar flares manage to penetrate Earth's weakening magnetic shield, damaging radiation could wreak havoc on the health on humankind.

THEORY: Pole Shift Hypotheses
Due to a variety of environmental or man-made factors, the north and south poles of Earth are not entirely static. There are many theories as to why this is, and what this means. The occurrence of a pole shift, where the poles would move dramatically, could cause the Earth's crust to move over the mantle and core—like an orange skin floating around above the pulpy fruit. This could result in major tsunamis, dramatic earthquakes and volcanoes, and intense climate change as the continents are pushed halfway across the globe from their current locations. A pole shift of this magnitude was predicted by psychic Edgar Cayce in 1934, who said it would start happening in the early 21st century.

What is the Dresden Codex?
The Dresden Codex is an ancient Maya text. While the Codex is known for its precise recording of lunar and solar eclipses, it is also recognized for hieroglyphs and icons that some say predict the destruction of the world. The Codex is currently located at the Saxon State Library in Dresden, Germany.
History
The Maya civilization paid great attention to one of the world’s most astounding natural phenomena: the eclipses of the sun and moon. They recorded these events and other astronomical phenomena in paper books created out of a type of bark. These books are now commonly referred to as ‘codices.’ During the invasion of the Americas, the Spaniards intentionally destroyed many of the books, however, four are known to have survived. They are known as the Dresden, Madrid, Paris, and Grolier codices.
The Maya Calendar
The Maya had several calendars: one, known as the tsolkin, was made up of 260 days. Another, referred to as the Long Count calendar, acted as a reference for historical events in Maya society. Because of the organization of the Long Count calendar, the dates can be linked to our Western calendar, allowing historians to measure the accuracy of the Maya’s method. The Long Count calendar began at 13.0.0.0.0; and in 2012 it will reach 13.0.0.0.0 once more, for the first time in over 5,000 years.
Lunar and Solar Eclipses
Illustrations in the Dresden Codex appear in the forms of both hieroglyphic scripts and icons. The illustrations specifically referencing eclipses are known as ‘eclipse glyphs.’ There are reports that during a lunar or solar eclipse, old Mesoamerican civilizations reacted with fear. Mesoamericanists have described scenes of chaos that included shouting of war cries and weeping. It is possible that murders also occurred during the solar eclipses as many may have feared that the world would truly become dark forever.
2012
Some people believe the text of the Dresden Codex predicts the end of the world in 2012. Many see a dragon-like being while others see an animal more like a crocodile. The creature, residing in the sky, has water pouring from its mouth, creating a world covered by water. The Maya Goddess O, also known as Chac Chel, is pouring water from a jar. The word Chac can mean both “great” and “red,” while Chel means “arc of heaven.” The combination of the color red with images of the full moon represents a prediction of strong rains. A menacing figure at the bottom of the page holds weaponry over the Earth. A number of anthropologists believe that two phrases in the Codex, meaning “black sky” and “black earth," imply the end of the world. While some believe the Maya were predicting a massive flood, there are numerous theories: everything from storms, to the crumbling of society’s ecosystems, as well as the reversal of the Earth’s magnetic fields. Still, anthropologists generally see the images in the Codex as simply part of Maya cosmology.

We could be in for a huge firework displa in 2012. The Sun will be approaching the peak of its 11-year cycle, called "solar maximum", so we can expect a lot of solar activity. Some predictions put the solar maximum of Solar Cycle 24 even more energetic than the last solar maximum in 2002-2003 (remember all those record breaking X-class flares?). Solar physicists are already getting excited about this next cycle and new prediction methods are being put to good use. But should we be worried?
According to one of the many Doomsday scenarios we
have been presented with in the run-up to the Mayan
Prophecy-fuelled "end of the world" in the year 2012, this scenario is actually based on
some science. What's more, there may be some correlation between the 11-year
solar cycle and the time cycles seen in the Mayan calendar, perhaps this
ancient civilization understood how the Sun's magnetism undergoes polarity
changes every decade or so? Plus, religious texts (such as the Bible) say that
we are due for a day of judgement, involving a lot of fire and brimstone. So it
looks like we are going to get roasted alive by our closest star on December 21st, 2012!
Before we go jumping to conclusions, take a step back
and think this through. Like most of the various ways the world is going to
end in 2012,
the possibility of the Sun blasting out a huge, Earth-damaging solar flare is very attractive to the
doomsayers out there. But let's have a look at what really happens during an
Earth-directed solar flare event, the Earth is actually very well protected. Although
some satellites may not be…
The Earth has evolved in a highly radioactive environment. The Sun constantly fires high-energy particles from its magnetically dominated surface as the solar wind. During solar maximum (when the Sun is at its most active), the Earth may be unlucky enough to be staring down the barrel of an explosion with the energy of 100 billion Hiroshima-sized atomic bombs. This explosion is known as a solar flare and the effects of which can cause problems here on Earth.

This explosion is known as a solar flare and the effects of which can cause problems here on Earth.
Before we look at the Earth-side effects, let's have a
look at the Sun and briefly understand why it gets so angry every 11 years or
so.
The Solar
Cycle
First and foremost, the Sun has a natural cycle
with a period of approximately 11 years. During the lifetime of each cycle, the
magnetic field lines of the Sun are dragged around the solar body by
differential rotation at the solar equator. This means that the equator is
spinning faster than the magnetic poles. As this continues, solar plasma drags
the magnetic field lines around the Sun, causing stress and a build up of
energy (an illustration of this is pictured). As magnetic energy
increases, kinks in the magnetic flux form, forcing them to the surface. These
kinks are known as coronal loops which become more numerous
during periods of high solar activity.
This is where the sunspots come in. As coronal loops continue
to pop up over the surface, sunspots appear too, often located at the
loop footpoints. Coronal loops have the effect of pushing the hotter surface layers of the Sun (the photosphere and chromosphere) aside, exposing the cooler convection zone (the reasons why the solar surface
and atmosphere is hotter than the solar interior is down to the coronal heating
phenomenon). As
magnetic energy builds up, we can expect more and more magnetic flux to be
forced together. This is when a phenomenon known as magnetic reconnection
occurs.
Reconnection is the trigger for solar flares of various sizes. As previously reported, solar flares from "nanoflares" to
"X-class flares" are very energetic events. Granted, the largest
flares my generate enough energy for 100 billion atomic explosions, but don't
let this huge figure concern you. For a start, this flare occurs in the low corona, right near the solar surface.
That's nearly 100 million miles away (1AU). The Earth is nowhere close to the blast.
As the solar magnetic field lines release a huge
amount of energy, solar plasma is accelerated and confined within the magnetic
environment (solar plasma is superheated particles like protons, electrons and
some light elements such as helium nuclei). As the plasma particles interact,
X-rays may be generated if the conditions are right and bremsstrahlung
is possible. (Bremsstrahlung occurs when charged particles interact, resulting
in X-ray emission.) This may create an X-ray flare.
The biggest problem with an X-ray flare is that we get
little warning when it is going to happen as X-rays travel at the speed of light (one of the record breaking 2003
solar flares is pictured left). X-rays from an X-class flare will reach the
Earth in around eight minutes. As X-rays hit our atmosphere, they are absorbed
in the outermost layer called the ionosphere. As you can guess from the name,
this is a highly charged, reactive environment, full of ions (atomic nuclei,
and free electrons).
During powerful solar events such as flares, rates of
ionization between X-rays and atmospheric gases increase in the D and E region
layers of the ionosphere. There is a sudden surge in electron production in
these layers. These electrons can cause interference to the passage of radio waves through the atmosphere, absorbing
short wave radio signals (in the high frequency range), possibly blocking
global communications. These events are known as "Sudden Ionospheric
Disturbances" (or SIDs) and they become commonplace during periods of high
solar activity. Interestingly, the increase in electron density during a SID
boosts the propagation of Very Low Frequency (VLF) radio, a phenomenon
scientists use to measure the intensity of X-rays coming from the Sun.
Coronal Mass
Ejections?
X-ray solar flare emissions are only part of the story. If the conditions are right, a coronal mass ejection (CME) might be produced at the site of the flare (although either phenomenon can occur independently). CMEs are slower than the propagation of X-rays, but their global effects here on Earth can be more problematic. They may not travel at the speed of light, but they still travel fast; they can travel at a rate of 2 million miles per hour (3.2 million km/hr), meaning they may reach us in a matter of hours.

They may not travel at the speed of light, but they still travel fast; they can travel at a rate of 2 million miles per hour (3.2 million km/hr), meaning they may reach us in a matter of hours.
This is where much effort is being put into space weather prediction. We have a
handful of spacecraft sitting between the Earth and the Sun at the Earth-Sun
Lagrangian (L1)
point with sensors on board to measure the energy and intensity of the solar
wind. Should a CME pass through their location, energetic particles and the
interplanetary magnetic field (IMF) can be measured directly. One mission
called the Advanced
Composition Explorer (ACE) sits
in the L1 point and provides scientists with up to an hour notice on
the approach of a CME. ACE teams up with the Solar and Heliospheric Observatory (SOHO) and the Solar TErrestrial
RElations Observatory (STEREO),
so CMEs can be tracked from the lower corona into interplanetary
space, through
the L1 point toward Earth. These solar missions are actively working
together to provide space agencies with advanced notice of
an Earth-directed CME.
So what if a CME reaches Earth? For a start, much
depends on the magnetic configuration of the IMF (from the Sun) and the
geomagnetic field of the Earth (the magnetosphere). Generally speaking, if both magnetic
fields are aligned with polarities pointing in the same direction, it is highly
probable that the CME will be repelled by the magnetosphere. In this case, the
CME will slide past the Earth, causing some pressure and distortion on the
magnetosphere, but otherwise passing without a problem. However, if the
magnetic field lines are in an anti-parallel configuration (i.e. magnetic
polarities in opposite directions), magnetic reconnection may occur at the
leading edge of the magnetosphere.
In this event, the IMF and magnetosphere will merge,
connecting the Earth's magnetic
field with the
Sun's. This sets the scene for one of the most awe inspiring events in nature:
the aurora.
Satellites
in Peril
As the CME magnetic field connects with the Earth's, high energy particles are injected into the magnetosphere. Due to solar wind pressure, the Sun's magnetic field lines will fold around the Earth, sweeping behind our planet. The particles injected in the "dayside" will be funnelled into the polar regions of the Earth where they interact with our atmosphere, generating light as aurorae. During this time, the Van Allen belt will also become "super-charged", creating a region around the Earth that could cause problems to unprotected astronauts and any unshielded satellites. For more on the damage that can be caused to astronauts and spacecraft, check out "Radiation Sickness, Cellular Damage and Increased Cancer Risk for Long-term Missions to Mars" and "New Transistor Could Side-Step Space Radiation Problem."

As if the radiation from the Van Allen belt wasn't
enough, satellites could succumb to the threat of an expanding atmosphere. As
you'd expect, as if the Sun hits the Earth with X-rays and CMEs, there will be
inevitable heating and global expansion of the atmosphere, possibly encroaching
into satellite orbital altitudes. If left unchecked, an aerobraking effect on satellites could cause them to
slow and drop in altitude. Aerobraking has been used extensively as a space flight tool to slow spacecraft down when being
inserted into orbit around another planet, but this will have an adverse
effect on satellites orbiting Earth as any slowing of velocity could cause it
to re-enter the atmosphere.
We Feel the
Effects on the Ground Too
Although satellites are on the front line, if there is
a powerful surge in energetic particles entering the atmosphere, we may feel
the adverse effects down here on Earth too. Due to the X-ray generation of
electrons in the ionosphere, some forms of communication may become patchy (or
be removed all together), but this isn't all that can happen. Particularly in
high-latitude regions, a vast electric current, known as an
"electrojet", may form through the ionosphere by these incoming
particles. With an electric current comes a magnetic field. Depending on the
intensity of the solar storm, currents may be induced down here
on the ground, possibly overloading national power grids. On March 13th 1989, six million people lost power in the Quebec region of Canada
after a huge increase in solar activity caused a surge from ground-induced
currents. Quebec was paralysed for nine hours whilst engineers worked on a
solution to the problem.
The short
answer to this is "no".
The longer answer is a little more involved. Whilst a
solar flare from out Sun, aimed directly at us, could cause secondary problems
such as satellite damage and injury to unprotected astronauts and blackouts,
the flare itself is not powerful enough to destroy Earth, certainly not in
2012. I dare say, in the far future when the Sun begins to run out of fuel and
swell into a red giant, it might be a bad era for life on
Earth, but we have a few billion years to wait for that to happen. There could
even be the possibility of several X-class flares being launched and by pure
bad luck we may get hit by a series of CMEs and X-ray bursts, but none will be
powerful to overcome our magnetosphere, ionosphere and thick atmosphere below.
"Killer" solar flares have been
observed on other stars. In 2006, NASA's Swift observatory
saw the largest stellar
flare ever observed 135
light-years away. Estimated to have unleashed an energy of 50 million trillion
atomic bombs, the II Pegasi flare will have wiped out most life on Earth if our
Sun fired X-rays from a flare of that energy at us. However, our Sun is not II
Pegasi. II Pegasi is a violent red giant star with a binary partner in a very
close orbit. It is believed the gravitational interaction with its binary
partner and the fact II Pegasi is a red giant is the root cause behind this
energetic flare event.
Doomsayers point to the Sun as a possible Earth-killer
source, but the fact remains that our Sun is a very stable star. It does not
have a binary partner (like II Pegasi), it has a predictable cycle (of
approximately 11 years) and there is no evidence that our Sun contributed to
any mass extinction event in the past via a huge
Earth-directed flare. Very large solar flares have been observed (such as the 1859 Carrington
white light flare)… but we
are still here.
In an added twist, solar physicists are surprised by
the lack of solar activity at the start of this 24th solar cycle,
leading to some scientists to speculate we might be on the verge of another Maunder minimum and "Little Ice Age". This is in stark contrast to
NASA solar
physicist's 2006 prediction that this cycle will be a "doozy".
This leads me to conclude that we still have a long
way to go when predicting solar flare events. Although space weather prediction
is improving, it will be a few years yet until we can read the Sun accurately
enough to say with any certainty just how active a solar cycle is going to be.
So, regardless of prophecy, prediction or myth, there is no physical way to say
that the Earth will be hit by any flare, let alone a big one in 2012.
Even if a big flare did hit us, it will not be an extinction event. Yes, satellites
may be damaged, causing secondary problems such as a GPS loss (which might
disrupt air traffic control for example) or national power grids may be
overwhelmed by auroral electrojets, but nothing more extreme than that.
But hold on, to sidestep this issue, doomsayers now
tell us that a large solar flare will hit us just as the Earth's
geomagnetic field weakens and reverses, leaving us unprotected from the ravages
of a CME… The reasons why this is not going to happen in 2012 is worthy of its
own article.
Apparently, on December 21st 2012, our planet will experience a powerful event. This time
we’re not talking about
Planet X, Nibiru or a “killer” solar flare,
this event will originate deep within the core of our planet,
forcing a catastrophic change in our protective magnetic field. Not only will
we notice a rapid reduction in magnetic field strength, we’ll also see the
magnetic poles rapidly reverse polarity (i.e. the north magnetic pole will be
located over the South Pole and vice versa). So what does this mean to us? If
we are to believe the doomsayers, we’ll be exposed to the vast quantities of
radiation blasting from the
Sun; with a reversing magnetic
field comes a weakening in the Earth‘s ability to deflect cosmic rays. Our armada
of communication and military satellites will drop from orbit, adding to the chaos on the ground. There will
be social unrest, warfare, famine and economic collapse. Without GPS, our
airliners will also plough into the ground…
Using the Mayan Prophecy as an excuse to create
new and explosive ways in which our planet may be destroyed, 20 12 2012 doomsayers use the geomagnetic shift
theory as if it is set in stone. Simply because scientists have said that it might
happen within the next millennium appears to be proof enough that it will
happen in four years time. Alas, although this theory has some scientific
backing, there is no way that anyone can predict when geomagnetic reversal
might happen to the nearest day or to the nearest million years…
Firstly, let’s differentiate between geomagnetic reversal and polar shift. Geomagnetic reversal is the change in the magnetic field of the Earth, where the magnetic north pole shifts to the South Polar Region and the south magnetic pole shifts to the North Polar Region. Once this process is complete, our compasses would point toward Antarctica, rather than northern Canada. Polar shift is considered to be a less likely event that occurs a few times in the evolutionary timescale of the Solar System. There are a couple of examples of planets that have suffered a catastrophic polar shift, including Venus (which rotates in an opposite direction to all the other planets, therefore it was flipped upside down by some huge event, such as a planetary collision) and Uranus (which rotates on its side, having been knocked off-axis by an impact, or some gravitational effect caused by Jupiter and Saturn). Many authors (including the doomsayers themselves) often cite both geomagnetic reversal and polar shift as being one of the same thing. This isn’t the case.

Many authors (including the doomsayers themselves) often cite both geomagnetic reversal and polar shift as being one of the same thing. This isn’t the case.
How often does it happen?
The reasons behind the
reversal of the magnetic poles is poorly understood, but it is all down to the
internal dynamics of Planet Earth. As our planet spins, the molten iron in the
core flows freely, forcing free electrons to flow with it. This convective
motion of charged particles sets up a magnetic field which bases its poles in
the North and South Polar Regions (a dipole). This is known as the dynamo
effect. The resulting magnetic field approximates a bar
magnet, allowing the field to envelop our planet.
This magnetic field passes through the core to
the crust and pushes into space
as the Earth’s magnetosphere, a protective bubble constantly
being buffeted by the solar wind. As the solar wind particles are
usually charged, the Earth’s powerful magnetosphere deflects the particles,
only allowing them into the polar cusp regions where the polar magnetic
fieldlines become “open.” The regions at which these energetic particles are
allowed to enter glow as aurorae.
Usually this situation can last for aeons (a
stable magnetic field threaded through the North and South Polar Regions), but
occasionally, the magnetic field is known to reverse and alter in strength. Why
is this?
Again, we simply do not know. We do know that
this magnetic pole flip-flop has occurred many times in the last few million
years, the last occurred 780,000 years ago according to ferromagnetic sediment.
A few scaremongering articles have said
geomagnetic reversal occurs with “clockwork regularity” – this is simply
not true. As can be seen from the diagram (left), magnetic
reversal has occurred fairly chaotically in the last 160 million years.
Long-term data suggests that the longest stable period between magnetic “flips”
is nearly 40 million years (during the Cretaceous period over 65 million years BC) and
the shortest is a few hundred years.
Some 2012 theories suggest that the Earth’s
geomagnetic reversal is connected to the natural 11-year solar
cycle. Again, there is absolutely no scientific evidence to support
this claim. No data has ever been produced suggesting a Sun-Earth
magnetic polarity change connection.
So, already this doomsday theory falters in that
geomagnetic reversal does not occur with “clockwork regularity,” and
it has no connection with solar dynamics. We are not due a magnetic flip as we
cannot predict when the next one is going to occur, magnetic reversals occur at
seemingly random points in history.
What causes geomagnetic reversal?
In a previous Universe Today article, we discussed the
efforts of geophysicist Dan Lathrop’s attempts to create his own “model Earth,”
setting a 26 tonne ball (containing a molten iron analogue, sodium) spinning to
see if the internal motion of the fluid could set up a magnetic field. This
huge laboratory experiment is testament to the efforts being put into understanding
how our Earth even generates a magnetic field, let
alone why it randomly reverses.
A
minority view (which, again is used by doomsayers to link
geomagnetic reversal with Planet X) is that there may be some external
influence that causes the reversal. You will often see associated with the Planet X/Nibiru claims that should this mystery
object encounter the inner Solar System during its highly elliptical orbit, the magnetic field disturbance
could upset the internal dynamics of the Earth (and the Sun, possibly
generating that “killer” solar flare I discussed back in June). This theory is a poor
attempt to link several doomsday scenarios with a common harbinger of doom
(i.e. Planet X). There is no reason to think the strong magnetic field of the
Earth can be influenced by any external force, let alone a non-existent planet (or was that a brown
dwarf?).
The magnetic field strength waxes and wanes…
New research into the Earth’s magnetic field
was published recently in the September 26th issue of Science,
suggesting that the Earth’s magnetic field isn’t as simple
as we once believed. In addition to the North-South dipole, there is a weaker
magnetic field spread around the planet, probably generated in the outer core of the Earth.
The Earth’s magnetic field is measured to vary in
field strength and it is a well known fact that the magnetic field strength is
currently experiencing a downward trend. The new research paper, co-authored by
geochronologist Brad Singer of the University of Wisconsin, suggests that the
weaker magnetic field is critical to geomagnetic reversal. Should the stronger
dipole (north-south) field reduce below the magnetic field strength of this
usually weaker, distributed field, a geomagnetic reversal is possible.
“The field is not always stable, the
convection and the nature of the flow changes, and it can cause the dipole
that’s generated to wax and wane in intensity and strength,” Singer said.
“When it becomes very weak, it’s less capable of reaching to the surface of the Earth, and what you start
to see emerge is this non-axial dipole, the weaker part of the field that’s
left over.” Singer’s research group analysed samples of ancient lava from volcanoes in Tahiti and Germany between 500,000
and 700,000 years ago. By looking at an iron-rich mineral called magnetite in
the lava, the researchers were able to deduce the direction of the magnetic
field.
The spin of the electrons in the mineral is
governed by the dominant magnetic field. During times of strong dipolar field,
these electrons pointed toward the magnetic North Pole. During times of weak
dipolar field, the electrons pointed to wherever the dominant field was, in
this case the distributed magnetic field. They think that when the weakened
dipolar field drops below a certain threshold, the distributed field pulls the
dipolar field off-axis, causing a geomagnetic shift.
“The magnetic field is one of the most
fundamental features of the Earth,” Singer said. “But it’s still one
of the biggest enigmas in science. Why [the flip] happens is something people
have been chasing for more than a hundred years.”
Our meandering magnetic pole
Although there appears
to be a current downward trend in magnetic field strength, the current magnetic
field is still considered to be “above average” when compared with the
variations measured in recent history. According to researchers at
Scripps Institution of Oceanography, San Diego, if the
magnetic field continued to decrease at the current trend, the dipolar field
would effectively be zero in 500 years time. However, it is more likely that
the field strength will simply rebound and increase in strength as it has done
over the last several thousand years, continuing with its natural fluctuations.
The positions of the magnetic poles are also
known to be wondering over Arctic and Antarctic locations. Take the magnetic
north pole for example (pictured left); it has accelerated north over
the Canadian plains from 10 km per year in the 20th Century to 40 km per year
more recently. It is thought that if the point of magnetic north continues this
trend, it will exit North America and enter Siberia in a few decades
time. This is not a new phenomenon however. Ever since James Ross’
discovery of the location of the north magnetic pole for the first time in
1831, it’s location has meandered hundreds of miles (even though today’s
measurements show some acceleration).
So, no doomsday then?
Geomagnetic reversal is an engrossing area of
geophysical research that will continue to occupy physicists and geologists for
many years to come. Although the dynamics behind this event are not fully
understood, there is absolutely no scientific evidence supporting the
claim that there could be a geomagnetic reversal around the time of December
21st, 2012.
Besides, the effects of such a reversal have been
totally over-hyped. Should we experience geomagnetic reversal in our lifetimes
(which we probably won’t), it is unlikely that we’ll be cooked alive by the
Solar Wind, or be wiped out by cosmic rays. It is unlikely that we’ll suffer
any mass extinction event (after all, early man, homo
erectus, lived through the last geomagnetic shift, apparently with ease).
We’ll most likely experience aurorae at all latitudes whilst the dipolar
magnetic field settles down to its new, reversed state, and there might be a
small increase in energetic particles from space (remember, just because the
magnetosphere is weakened, doesn’t mean we wont have magnetic protection), but
we’ll still be (largely) protected by our thick atmosphere.
Satellites may malfunction and migrating birds may become confused, but to
predict world collapse is a hard pill to swallow.
In conclusion:
- Geomagnetic
reversal is chaotic in nature. There is no way we can predict it.
- Simply
because the magnetic field of the Earth is weakening does not mean it is
near collapse. Geomagnetic field strength is “above average” if we compare
today’s measurements with the last few million years.
- The
magnetic poles are not set in geographical locations, they move (at
varying speeds) and have done ever since measurements began.
- There is
no evidence to suggest external forcing of internal geomagnetic dynamics
of the Earth. Therefore there is no evidence of the solar
cycle-geomagnetic shift connection. Don’t get me started on Planet X.
Once again, we find another 2012 doomsday scenario to be flawed in so many
ways. There is no doubt that geomagnetic reversal will happen in the future for
Earth, but we’re talking about time scales anything from an optimistic (and
unlikely) 500 years to millions of years, certainly not in the coming four
years…
How Earth Could End
If the apocalypse doesn't occur in 2012, that
leaves plenty of time for another catastrophe to strike. Imagine these
scenarios… the way some believe the world could end.In the GRAY GOO scenario…
Out-of-control mini self-replicating robots would consume
all of the matter on Earth in their endless quest to clone themselves. Not an
actual "goo," the tiny nano-robots would move across the planet,
replicating infinitely until they run out of raw matter to use. The Earth would
be completely overtaken by these machines, and organic life would be no more.
In the MAN-MADE BLACK HOLE scenario…
The CERN Large Hadron Collider in France, the largest and
most advanced machine on the planet, would accidentally create a black hole on
Earth. A giant particle accelerator used by physicists to study the universe's
smallest known particles, it works by crashing beams of them together at high
speeds, recreating Big Bang conditions. While the chances of this happening are
slim, if the LHC were to accidentally create a black hole and it grew out of
control, first the CERN facility, then the countries of France and Switzerland,
and eventually the Earth itself would be sucked into its vacant depths.
In the ASTEROID IMPACT scenario…
An asteroid as large as
the one that killed the dinosaurs would obliterate the human race. We are, in
fact, overdue for another large asteroid collision here on Earth. If it hit,
humans, as the dominant life form, would be in danger of immediate
extinction—the asteroid would immediately vaporize all living things for miles
around and send waves of destruction around the world.
In the GLOBAL CLIMATE CHANGE scenario…
Minor oddities like
snow in June and shorts in January would give way to floods overtaking coastal
cities, unending droughts, extreme hurricanes, melted glaciers, and acidic
oceans. Quickened by pollution and the human race's ever-expanding carbon
footprint, Earth's ability to support thriving life would diminish more and
more quickly, until finally it would be uninhabitable.
In the EXTREME OVERPOPULATION scenario…
There would be no food.
No water. No resources to go around. The Earth's population has more than
doubled in the past 50 years. If it continues to grow and becomes too much to
control, sanitation would be more and more difficult to accomplish and people
would live in squalor. Disease, starvation, and dehydration would claim the
lives of the weak and only the strong would survive, attempting to continue the
reign of the human race on planet Earth.
In the NUCLEAR DISASTER scenario…
Tensions in the world
would continue to grow, and war would become more and more sophisticated. There
are over 20,000 nuclear weapons in the world today. If we experienced World War
III, we would all be in danger of a global nuclear holocaust. When the bombs
did drop, nuclear fallout in the form of deadly radiation and electromagnetic pulses
would have immediate and lasting effects on humanity—and if enough of them were
deployed, life would no longer be possible in the nuclear wasteland.
In the DEADLY EPIDEMIC scenario…
A natural spread of a
new disease—or biological warfare utilizing existing ones—would devastate the
world's population, as healthy humans would be decimated by lethal illness.
We've seen it before: plague killed as much as one-third of Europe's population
in the 14th century, and the Spanish Flu of the late 1910s is believed to have
ended more lives than World War I. Even more frightening, it is now
technologically possible to equip missiles and bombs with diseases like
smallpox, against which much of the world is no longer immune.
In the DEATH OF THE BEES scenario…
The 30 percent of the
world's food that relies on bee activity would gradually disappear, causing
food shortages and an inevitable struggle for survival. This is not as
far-fetched as it may seem. Colony Collapse Disorder (CCD) is an actual
syndrome in which all of a colony's worker bees mysteriously die off, leaving a
lone queen wandering around the hive. In the winter of 2008, 36 percent of the
commercial beehives in the U.S. succumbed to CCD, the direct cause is unknown,
and there is no known cure.
Einstein and Poleshifts
“His idea is original, of great simplicity, and—if it continues to prove
itself—of great importance to everything that is related to the history of the
earth’s surface.” – Einstein
Upon learning of Charles
Hapgood’s pole-shift theory, Einstein was struck by the possibility of
explaining the history of Earth’s surface. Inspect a letter Einstein wrote to
Charles Hapgood and read the famous scientist's introduction to Hapgood's book The
Path of the Pole. The English translations are below and his original
writings are to the right.

Dear Sir:
I have read already some years ago in a popular article about the idea that
excentric masses of ice, accumulated near a pole, could produce from time to
time considerable dislocations of the floating rigid crust of the earth. I have
never occupied myself with this problem but my impression is that a careful
study of this hypothesis is really desirable.
I think that our factual knowledge of the underlying facts is at present
not precise enough for a reliable answer based exclusively on calculations.
Knowledge of geological and paleontological facts may be of decisive importance
in the matter. In any case, it would not be justified to discard the idea a
priori as adventurous.
The question whether high pressure may not be able to produce fusion of
nuclei is also quite justified. It is not known to me if a quantitative theory
has been worked out by astrophysicists. The action of pressure would not be a
static effect as classical mechanics would suggest, but a kinetic effect
corresponding not to temperature but to degeneracy of gases of high density.
You should correspond about this with an astro-phycisist experienced in quantum
theory, f.i. Dr. L. Schwarzschild at the Princeton University Observatory.
Sincerely yours,
Albert Einstein.
Foreword to the First Edition
by Albert Einstein
by Albert Einstein
I frequently receive communications from people who wish to consult me
concerning their unpublished ideas. It goes without saying that these ideas are
very seldom possessed of scientific validity. The very first communication,
however, that I received from Mr. Hapgood electrified me. His idea is original,
of great simplicity, and—if it continues to prove itself—of great importance to
everything that is related to the history of the earth’s surface.
A great many empirical data indicate that at each point on the earth’s
surface that has been carefully studied, many climatic changes have taken
place, apparently quite suddenly. This, according to Hapgood, is explicable if
the virtually rigid outer crust of the earth undergoes, from time to time,
extensive displacement over the viscous, plastic, possibly fluid inner layers.
Such displacements may take place as the consequence of comparatively slight
forces exerted on the crust, derived from the earth’s momentum of rotation,
which in turn will tend to alter the axis of rotation, which in turn will tend
to alter the axis of rotation of the earth’s crust.
In a polar region there is continual deposition of ice, which is not
symmetrically distributed about the pole. The earth’s rotation acts on these
unsymmetrically deposited masses, and produces centrifugal momentum that is
transmitted to the rigid crust of the earth. The constantly increasing
centrifugal produced in this way will, when it has reached a certain point,
produce a movement of the earth’s crust over the rest of the earth’s body, and
this will displace the polar regions toward the equator.
Without a doubt the earth’s crust is strong enough not to give way
proportionately as the ice is deposited. The only doubtful assumption is that
the earth’s crust can be moved easily enough over the inner layers.
The author has not confined himself to a simple presentation of this idea.
He has also set forth, cautiously and comprehensively, the extraordinarily rich
material that supports his displacement theory. I think that this rather
astonishing, even fascinating, idea deserves the serious attention of anyone
who concerns himself with the theory of the earth’s development.
To close with an observation that has occurred to me while writing these
lines: If the earth’s crust is really so easily displaced over its substratum
as this theory requires, then the rigid masses near the earth’s surface must be
distributed in such a way that they give rise to displace the crust by
centrifugal effect. I think that this deduction might be capable of
verification, at least approximately. This centrifugal momentum should in any
case be smaller than that produced by the masses of deposited ice.
