Get ready for the next big bombshell in the man-made warming debate. The world’s most sophisticated particle study laboratory—CERN in Geneva—will soon announce that more cosmic rays do, indeed, create more clouds in earth’s atmosphere. More cosmic rays mean a cooler planet. Thus, the solar source of the earth’s long, moderate 1,500-year climate cycle will finally be explained.
Cosmic rays and solar winds are interesting phenomena—but they are vastly more relevant when an undocumented theory is threatening to quadruple society’s energy costs. The IPCC wants $10 gasoline, and “soaring” electric bills to reduce earth’s temperatures by an amount too tiny to measure with most thermometers.
In 2007, when Fred Singer and I published Unstoppable Global Warming Every 1,500 Years, we weren’t terribly concerned with cosmic rays. We knew the natural, moderate warming/cooling cycle was real, from the evidence in ice cores, seabed sediments, fossil pollen and cave stalagmites. The cycle was the big factor that belied the man-made warming hysteria of the Intergovernmental Panel on Climate Change.
When Willi Dansgaard and Hans Oeschger discovered the 1,500 year cycle in the Greenland ice cores in 1984, they knew immediately that it was solar-powered. They’d seen exactly the same cycle in the carbon 14 molecules in trees, and in the beryllium 10 molecules in ice cores. Both sets of molecules are formed when cosmic rays strike our atmosphere. The cycle had produced a whole series of dramatic, abrupt Medieval-Warming-to-Little-Ice-Age climate changes.
The IPCC, for its part, announced that the sun could not be the forcing factor in any major climate change because the solar irradiation was too small. IPCC did not, however, add up the other solar variations that could amplify the solar irradiation. Nor had the IPCC programmed its famed computer models with the knowledge of the Medieval Warming (950–1200 AD), the Roman Warming (200 BC–600 AD), or the big Holocene Warmings centered on 6,000 and 8,000 BC.
The IPCC apparently wanted to dismiss the sun as a climate factor—to leave room for a CO2 factor that has only a 22 percent correlation with our past thermometer record. Correlation is not causation—but the lack of CO2 correlation is deadly to the IPCC theory.
Henrik Svensmark of the Danish Space Research Institute added the next chapter in the climate cycle story, just before our book was published. His cloud chamber experiment showed natural cosmic rays quickly created vast numbers of tiny “cloud seeds” when our mix of atmospheric gases was bombarded with ultra-violet light. Since clouds often cover 30 percent of the earth’s surface, a moderate change in cloud cover clearly could explain the warming/cooling cycle.
Svensmark noted the gigantic “solar wind” that expands when the sun is active—and thus blocks many of the cosmic rays that would otherwise hit the earth’s atmosphere. When the sun weakens, the solar wind shrinks. Recently, the U.S. Solar Observatory reported a very long period of “quiet sun” and predicted 30 years of cooling.
Last year, Denmark’s University of Aarhus did another experiment with a particle accelerator that fully confirmed the Svensmark hypothesis: cosmic rays help to make more clouds and thus could cool the earth.
The CERN experiment is supposed to be the big test of the Svensmark theory. It’s a tipoff, then, that CERN’s boss, Rolf-Dieter Heuer, has just told the German magazine Die Welt that he has forbidden his researchers to “interpret” the forthcoming test results. In other words, the CERN report will be a stark “just the facts” listing of the findings. Those findings must support Svensmark, or Heuer would never have issued such a stifling order on a major experiment.

Henrik Svensmark did the documentary, The Cloud Mystery, I watched it to actually do research on climate change and learn about science. It debunks AGW Global Warming, just like Galileo debunked the geocentric. I never knew how hard it was to convince people that the Sun actually affected temperatures on Earth!Get ready for the next big bombshell in the man-made warming debate. The world’s... more

Scientists capture antimatter atoms in particle breakthrough

STORY HIGHLIGHTS
* Antihydrogen atoms were trapped in a magnetic field
* Matter and antimatter annihilate each other on contact
* "It's taken us five years to get here," says Professor Jeffrey Hangst
* CERN's next ambition is to create a beam of antimatter
(CNN) -- Scientists have captured antimatter atoms for the first time, a breakthrough that could eventually help us to understand the nature and origins of the universe.
Researchers at CERN, the Geneva-based particle physics laboratory, have managed to confine single antihydrogen atoms in a magnetic trap.
This will allow them to conduct a more detailed study of antihydrogen, which will in turn allow scientists to compare matter and antimatter.
Understanding antimatter is one of the biggest challenges facing science -- most theoretical physicists and cosmologists believe that at the Big Bang, when the universe was created, matter and antimatter were produced in equal amounts.
However, as our world is made up of matter, antimatter seems to have disappeared.
Understanding antimatter could shed light on why almost everything in the known universe consists of matter.
Antimatter has been very difficult to handle because matter and antimatter don't get on, destroying each other instantly on contact in a violent flash of energy.
It's taken us five years to get here, this is a big milestone
--Professor Jeffrey Hangst
In a precursor to today's experiment, in 2002 scientists at CERN produced antihydrogen atoms in large quantities, but they had an incredibly short lifespan -- just several milliseconds -- because the antihydrogen came into contact with the walls of their containers and the two annihilated each other.
In this latest experiment the lifespan of the antihydrogen atoms was extended by using magnetic fields to trap them and thus prevent them from coming into contact with matter.
The researchers created 38 antihydrogen atoms and held on to them for about a tenth of a second, which is long enough to study them says Professor Jeffrey Hangst, one of the team of CERN scientists who worked on the program.
Hangst and his colleagues produced a magnet field which was strongest near the walls of the trap, falling to a minimum at the center, causing the atoms to collect there in a vacuum.
"We could have held them for much longer... I am just full of joy and relief, it's taken us five years to get here, this is a big milestone," Hangst told CNN.
To trap just 38 atoms, they had to run the experiment 335 times, says Nature which published the report findings.
Hangst added: "This was ten thousand times more difficult than creating untrapped antihydrogen atoms.
"This will help us understand the structure of space and time. For reasons that no one yet understands, nature ruled out antimatter... this inspires us to work that much harder to see if antimatter holds some secret."
Malcolm Longair, professor of natural philosophy at Cambridge University, told CNN that CERN's results were a considerable achievement.
"At the Big Bang we believe the temperatures were very very high and we understand in theory why antimatter disappeared but there is no physical theory to back it up."
Antimatter was first predicted in 1931 by the British physicist Paul Dirac, who theorized that antimatter is ordinary matter in reverse.
CERN's next ambition is to create a beam of antimatter which they hope will allow them to unpeel more of the mysteries surrounding it.Scientists capture antimatter atoms in particle breakthrough

Antimatter galaxies and dark matter have long haunted physicists' theories, but no instrument in orbit has had the power to confirm or deny their existence. Now a $1.5 billion cosmic ray detector scheduled for launch in 2010 could usher in a new era for discovering all that's weird and wonderful about the universe.
Cosmic rays consist of high-energy particles that emerge from catastrophic events such as supernovas, and may also hold the clues to whether antimatter galaxies and dark matter truly exist. Detecting cosmic rays firsthand from the ground has proved difficult, because they collide with atoms in Earth's atmosphere and break up into a shower of secondary particles.
"Earth's atmosphere absorbs everything, so you cannot study primary cosmic rays until you go to space," said Samuel Ting, an MIT physicist who first proposed a large cosmic ray detector back in 1994.Antimatter galaxies and dark matter have long haunted physicists' theories, but... more

There is a dichotomy in that article - if nothing, not even light, can escape from a black hole, then no Cosmic Rays could emanate from them either, but they do. Which brings me to ask if those cosmic rays are the hyper-subliminated material of all that the black hole ingests which is spewed out in the form of cosmic ray?
