LaViolette first presented evidence for his theory in his 1983 Ph.D. dissertation which he worked on at Portland State University in Oregon. Astronomical evidence he had gathered indicated that every 10,000 years or so intense volleys of cosmic ray electrons are unleashed from outbursts of our Galaxy's core and make their way to us traveling at close to the speed of light. Further he reasoned that one such "Galactic superwave" had bombarded our solar system near the end of the ice age causing large quantities of cometary dust to enter the solar system along with an increased influx of meteors and comets. He proposed that this triggered a sequence of events including the occurrence of super-sized solar flare outbursts that led to the extinction of the large mammals 13 thousand years ago.
early stages of the last ice age cosmic dust incursion episodes had occurred. His theory predicted that he should also find high concentrations of cosmic dust during the interval from 11,000 to 14,000 years ago that spanned the extinction of the large Pleistocene mammals. But at that time he was unable to complete this crucial test of his theory because of lack of
Bullet-like pieces of what is thought to be an ancient meteorite shower have
been found embedded in mammoth tusks and bison bone.
The discovery of the 2–5 millimetre holes left by meteorites opens a window
into a impact event thought to have happened over Alaska and Russia tens of
thousands of years ago. And it could provide a whole new way to chart
impacts from space.
The fragments, found in seven mammoth tusks and the skull and horns of a
Siberian bison, match the geochemical composition of iron meteorites. "We
think that the micrometeorites came from an air-burst of a meteor 30,000 to
34,000 years ago," says Richard Firestone,

Chandra discovers light echo from the Milky Way's black hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center.
A light echo was produced when X-ray light generated by gas falling into the Milky Way's supermassive black hole, known as Sagittarius A* (pronounced "A-star"), was reflected off gas clouds near the black hole. While the primary X-rays from the outburst would have reached Earth about 50 years ago, the reflected X-rays took a longer path and arrived in time to be recorded by Chandra
"This dramatic event happened before we had satellites in space that could detect it," said Michael Muno of the California Institute of Technology in Pasadena. "So, it's remarkable that we can use Chandra to dig into the past and see this monster black hole's capacity for destruction."
Should a superwave arrive, our most immediate worry would be the electromagnetic pulse (EMP) that it would carry at its forefront. This high intensity electromagnetic shock front would send high voltages coursing along any electrically conductive object.(1) Upon arrival, it would:
? create high-voltage surges on the power line grid, shorting out power line transformers and tripping line circuit breakers, resulting in global power blackouts.
? fry satellites and destroy all nonhardened electronic equipment connected to the electric power grid, resulting in loss of electronic communications (TV, telephone, GPS system, etc.) -- airplane crashes would be inevitable;
? accidentally electrocute people who happened to be touching a large metal surface.
? ionize the Earth's atmosphere and consequently destroy the ozone layer, thereby increasing the Earth's exposure to harmful UV rays and ionizing radiation. The atmospheric electron shower produced by the superwave cosmic rays along with the increased penetration of solar UV would raise the incidence of skin cancer as well as the rate of genetic mutation.
There is the strong possibility that the EMP would also be accompanied by a gravity wave. The tidal force exerted on the Earth as it passed could trigger earthquakes and volcanic eruptions.
Before we had a Solar System, there was just a giant cloud of cold molecular hydrogen. And then something happened to the cloud that caused it to collapse. Perhaps it was the interaction with a passing star, or maybe the shockwave from a nearby supernova triggered the collapse. After that, the cloud began to collapse because of its collective gravity
Earths Ice Ages
" There have been several ice ages in the history of the Earth.
What is commonly called the ice age is actually the most recent (Quaternary) (NL) which began about two million years ago, and was characterized by cold (glacial), and relatively warm (interglacial) phases.
Four major continental glaciations are recorded in North America.
- he last (Wisconsin) began about 70,000 years ago, and ended 10,000 years ago.
Circa 10,000 BCE — North America: Dire Wolf, Smilodon, Cave Lion, Giant beaver, Ground sloth, Mammoth, American Mastodon, American Camel, American Equine, and American lion all become extinct.
— Banksia kingii from Tasmania and probably other members included in the genus.
— Homo floresiensis, the human's last known surviving close relative, becomes extinct.
7th millennium BCE
Circa 6,000 BCE — Steppe Wisent, a bison species inhabiting steppe from Asia to North America, disappears.
- Irish Elk becomes extinct, possibly due to changes in the ecosystem.
 5th millennium BCE
But the trail gets hotter - literally. Moon shots from the 1960s revealed glass on the moon. Glass is made from intense bursts of heat on sand. The event happened within the last 30,000yrs ago. Ancient petrogrpahs of primirtive people (archeological carvings) from that era (12,000+y.a.) show the sun causing extreme energy bursts changing earth atmosphere.
Past surveys of stars have found cycles similar to the sun's 11-year one.
Similar storms back in 1859 and 1921 caused worldwide chaos, wiping out telegraph wires on a massive scale.
The 2012 storm has the potential to be even more disruptive.
"The general consensus among general astronomers (and certainly solar astronomers) is that this coming Solar maximum (2012 but possibly later into 2013) will be the most violent in 100 years," astronomy lecturer and columnist Dave Reneke said
We have seen that it is conceivable that the break-up of the Kharsag community through a return of ice age conditions could have occurred earlier that the O'Briens believed - that is, before 10,000 B.C. O'Brien had worked out this date for the founding of Kharsag, about 8,200 B.C., From the fact that the cedars of Lebanon had existed from about that time. If he was wrong about Kharsag being situated in Lebanon, then that date was purely arbitrary. If Kharsag was affected by the 9,600 B.C. catastrophe, and it had flourished for over 2,000 years, as O'Brien believes, that would push its foundation back to perhaps 11,500 B.C. Is it not possible that work began on the subterranean cities at that time? Collins cites a Persian legend in which a shepherd called Yima is told by God to build a 'var' - an underground city or fortress - to protect men and animals from freezing conditions brought about by an evil demon. Nearly 2,000 human beings are to be taken into the city for their protection.
Could this legend also be referring to the underground cities of Cappadocia? There was a strong connection between Kurdistan and its neighbor Persia, in which case there is an arguable connection between these subterranean cites and the end of the last ice age.
The Golden Age of man, has been dismissed as
folly. But if it was truly fiction, how can we explain
the existence, of highly stylized rock art paintings,
an expression of mythic beliefs, of similar design
and similar execution, (often by spit painting), in
southern Europe at Lascaux, 22,000 years ago, in
Australia, 25,000 years ago and in the Americas at
Pedra Furada, 32,000 years ago?
Among the animals, depicted in the Brazilian paintings
at Pedra Furada, were horses and camels, both
abundant, in the Americas at that time, and both sudden
victims of a mass extermination, 12,500 years ago,
thousands of years, before the traditional dates, for the
invention of culture.
Pablo Picasso, after examining the Lascaux (France)
artwork of twenty-two millennia past, and comparing it,
to advances, in twentieth-century modern art, exclaimed,
"We have invented nothing!" Can historians still insist,
on man and civilization, as recently founded, in the
