Solar system caught in an interstellar tempest

The solar system is travelling through much stormier skies than we thought, and might even be about to pop out of the huge gas cloud we have been gliding through for at least 45,000 years. That's the implication of a multi-decade survey of the interstellar wind buffeting the solar system, which has revealed an unexpected change in the wind's direction.

...

he fact that the wind is shifting over the span of mere decades means that the interior of the cloud is either unusually turbulent, or that the solar system is a mere 1000 or so years away from punching its way out.

...

Since the 1970s, we've known that the solar system is moving through a cloud of interstellar gas about 30 light years across, out on the edge of the Milky Way galaxy. The sun's motion through the cloud creates an apparent wind of interstellar particles that slams into the heliosphere.

...

"While there had been hints that something was changing in the environment of the sun, when we finally put all the historical data together it became clear that one can make a strong scientific statement that this change has actually occurred," says Frisch. What the change means is still up for debate. We could be nearing the cloud's edge, or we could still be in the thick of it, pushing our way through an interstellar storm.

"It's possible we're seeing a structure that is not necessarily an edge," says Robert Meier,... who helped make the original STP 72-1 measurements. "A change of direction of flow in a stream could mean you're near the bank, or that there's a rock in the middle of the stream or something like that. It's always harder to figure out what's going on when you're in the middle."

...”the intelligence of the human race basically doubles over the course of a few days.”

The way things are going, here on Earth, I think that we are going farther into the “energy damping field” and becoming more stupid, day by day! Just sayin’
