Intense Sunspot Activity 8,000 to 11,400 Years Ago
An October 27, 2004 study, led by Sami Solanki of the Max Planck Institute in Germany, used carbon-14 in dead and buried trees to learn about sunspot activity going back as far as 11,400 years. Solanki's conclusion is that sunspot activity hasn't been as intense as it is now for at least 8,000 years or more. More sunspots is usually linked to increased solar activity. The implication is that scientists might be able to better understand why the climate has changed in the past and how future changes can be more accurately predicted depending upon sunspot fluctuations.
L-R: Orchid-colored image of plasma electrical discharge in laboratory by electrical engineer
Anthony Peratt, Ph.D. Dr. Peratt assembled petroglyphs known as “squatter man” to compare
with his lab plasma electrical discharge in his hypothesis that “immense and terrifying plasma
configurations were seen in the sky of our ancestors.” Source: Thunderbolts.info.
[ Editor's Note: Electrical engineer, Anthony Peratt, Ph.D., compared the “squatter man” petroglyphs above with his plasma electrical discharge lab experiments that produced a disk or donut-like torus around a linear discharge column bent by magnetic fields induced by intense current flow. From the viewpoint of the observer, the edges of the upper disk may appear to point up forming “arms” and those of the lower torus may appear to point down forming “legs.” The underlying “hourglass” pattern, with many subtle variations, occurs around the world.
Dr. Peratt wrote in his December 6, 2003, paper for IEEE Transactions On Plasma Science entitled “Characteristics for the Occurrence of a High-Current, Z-Pinch Aurora as Recorded in Antiquity: “As the same morphological types are found worldwide, the comparisons suggest the occurrence of an intense aurora, as might be produced if the solar wind had increased between one and two orders of magnitude millennia ago.” ]
Schoch: “We have petroglyphs, which I believe humans were recording major solar outbursts and plasma – that is electrically charged particles hitting the atmosphere and seen in the skies. We can now reconstruct such plasma events in the lab (for comparison to petroglyphs), but have not seen in historical times.
In fact, I think that on Easter Island we have some very good records of this in the rongorongo script, which I believe is a copy of a record of a major solar outburst. I want to point out that it was my wife, Katie, who first made the connection between the rongorongo script, the petroglyphs, and the plasma configurations. It is, I believe, an important and major discovery, and I would like to see her receive credit for it.”
