I was answering your question, not trying to validate the statement. But since you insist... It is completely ignorant, astrophysically speaking, to state that "unless we're getting sucked into it" that the super-massive (astronomers an astrophysists words for it, not mine) black hole in the center of our universe, which keeps stars in orbit around it from a distance of 100,000 light years, can not have any effect on our solar system, which is only 26,000 light years from the core. It seems ludicrous to think that news about the lack of solar winds would not include possible explanations as to why! But apparently, you have all the answers to everything, so we just might as well shut this site down, as well as the rest of the internet, and just have a blog that you write, oh wise one! If you're wonder where this came from, it's your attitude to open discussion, which is more than apparent from your posts!

What causes an ice age is fascinating. It seems that when the sun has sunspots, solar wind speeds up and increases. This blocks a lot of the cosmic rays hitting the earth and increases the Earths magnetic protection. Also the flares and sunspot activity add to atmospheric tempature increases from the solar interaction. When there are no sunspots, the cosmic rays start to bombard the Earth. What happens next is interesting. The cosmic rays cause cloud formatiom and this decreases the amount of sunlight reaching the earth's surface. The oceans begin to cool and then the global tempature cools.
What is even more fascinating is, the earth has been heating up because of the excess in sunspot activity in recent decades. The Earth has melted a lot of ice, and this is in the atmosphere. Now last winter was the snowiest in 138 years. Yet, even though the global tempature was down since 2001 and at a five year low, it was still higher than in the 70's and 80's. With each year getting colder, the moisture will be ever squeezed from the air and the winters will be colder and longer. It will not take many years to be in a full blown ice age.
To date there have been only a handful of old cycle sunspots only lasting hours, and no new cycle ones. If you look closely at the chart someone posted before me, you will see that the current data has already cut into the predicted cycle marked in red.
get your coats on... it's going to get cold... very cold indeed.
Sorokhtin believes that a lack of sunspots does indicate a coming cooling period based on certain past trends and early records. In fact, he calls manmade climate change "a drop in the bucket" compared to the fierce and abrupt cold that can potentially be brought on by inactive solar phases.
The spacecraft is powered by the decay of a radioactive isotope. Over its 17-plus years, the power has been steadily dropping. The spacecraft no longer can run all of its communications, heating and scientific equipment simultaneously. "We expect certain parts of the spacecraft to reach 2 degrees Celsius pretty soon," said Richard Marsden, ESA project scientist and mission manager. This temperature drop will block the fuel pipes, making the spacecraft impossible to maneuver.
Ulysses Reveals Global Solar Wind Plasma Output at 50-Year Low - PASADENA, Calif. -- Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system.
"The sun's million mile-per-hour solar wind inflates a protective bubble, or heliosphere, around the solar system. It influences how things work here on Earth and even out at the boundary of our solar system where it meets the galaxy," said Dave McComas, Ulysses' solar wind instrument principal investigator and senior executive director at the Southwest Research Institute in San Antonio. "Ulysses data indicate the solar wind's global pressure is the lowest we have seen since the beginning of the space age."
The sun's solar wind plasma is a stream of charged particles ejected from the sun's upper atmosphere. The solar wind interacts with every planet in our solar system. It also defines the border between our solar system and interstellar space.
This border, called the heliopause, surrounds our solar system where the solar wind's strength is no longer great enough to push back the wind of other stars. The region around the heliopause also acts as a shield for our solar system, warding off a significant portion of the cosmic rays outside the galaxy.
"Galactic cosmic rays carry with them radiation from other parts of our galaxy," said Ed Smith, NASA's Ulysses project scientist at the Jet Propulsion Laboratory in Pasadena, Calif. "With the solar wind at an all-time low, there is an excellent chance the heliosphere will diminish in size and strength. If that occurs, more galactic cosmic rays will make it into the inner part of our solar system."
Galactic cosmic rays are of great interest to NASA. Cosmic rays are linked to engineering decisions for unmanned interplanetary spacecraft and exposure limits for astronauts traveling beyond low-Earth orbit.
In 2007, Ulysses made its third rapid scan of the solar wind and magnetic field from the sun's south to north pole. When the results were compared with observations from the previous solar cycle, the strength of the solar wind pressure and the magnetic field embedded in the solar wind were found to have decreased by 20 percent. The field strength near the spacecraft has decreased by 36 percent.
"The sun cycles between periods of great activity and lesser activity," Smith said. "Right now, we are in a period of minimal activity that has stretched on longer than anyone anticipated."
It's hot... It's very,very hot.

"Prepare for Unforeseen Consequences"
The solar wind's effects are also felt at the edge of the solar system, where the Voyager 1 and Voyager 2 probes have entered the heliosphere's outer envelope layer. Voyager 2 arrived at the solar system edge later than Voyager 1, yet found that that boundary to be almost a billion miles closer – a possible sign of the shrinking protective bubble.
"For the first time we've got a spacecraft that flies over the poles of the sun," said Ed Smith, a Ulysses scientist at the Jet Propulsion Laboratory in Pasadena, Calif. "That allows us to see changes in the heliosphere in three dimensions, or four if you count time."
At least one lingering question still stands out — whether the current weak solar winds represent an isolated phase or a longer term trend in future solar cycles.
Typically a solar minimum lasts about a year, but this low point has gone on since the summer of 2006.
