It washes away parts of the upper atmosphere leaving us exposed to more

In related news, eventually the Sun is going to turn into a red giant and engulf the Earth, thus utterly destroying it. -- David Barts Portland, OR |

We are entering a part of the galaxy that is relatively dense and we don't know what will happen. This is uncharted territory. |

Wrong! *We are entering a part of the galaxy that is relatively dense and we don't know what will happen. This is uncharted territory. There is nothing I see on that linked page to back up that assertion. Moreover, how exactly are we "entering a part of the galaxy that is relatively dense"? We're on one of the rotating spiral arms of the Milky way. We're moving at pretty much the same speed as the rest of the arm. It's very hard to "enter" a part of the galaxy we're pacing at the same speed. Absent any links that actually back up what you're trying to assert, I find your assertions to be highly questionable. -- David Barts Portland, OR |

The Sun's giant magnetic field thwarts much of the dust from entering the solar system. But the magnetic field weakens periodically, on a cycle that lasts roughly 22-years. The cycle is related to an 11-year cycle of sunspot activity. This is the first of the related dust storms that has been seriously monitored by a spacecraft. Some day, the influx could get worse. The solar system is plowing toward the fringes of a galactic cloud known as the G-cloud. "The time of the entry into the G-cloud is unknown, but is expected to occur any time in the next 10,000 years," Landgraf said. "There will be a constant increase [in dust rates], because the G-cloud is more dense than the local interstellar cloud that is now surrounding our Sun." http://www.space.com/scienceastronom...rm_030814.html |

But the magnetic field weakens periodically, on a cycle that lasts roughly 22-years. The cycle is related to an 11-year cycle of sunspot activity. These are two distinct phenomena. The solar wind is not the same thing as an intrastellar dust cloud. There was nothing in the link you furnished that indicated the increased amount of intrastellar dust would accelerate the rate of atmospheric depletion (which is such a minute fraction of the atmosphere per year that it's of no immediate threat). And did you notice the statement in that article that no serious consequences are expected from passing through that dust cloud? There *might* be a slight increase in the number of visible meteors ("shooting stars") at night, that's about all they anticipate. Hardly a doomsday scenario. In fact, seeing more shooting stars at night sounds like a plus. -- David Barts Portland, OR |

I said no such thing. I said the atmosphere would have reduced ability to protect us from cosmic rays. http://www.ibex.swri.edu/ |

I said no such thing. Actually, you did. You said it was "getting troublesome" and that it "washes away parts of the atmosphere". If part of the atmosphere is getting "washed away", that's depletion. I said the atmosphere would have reduced ability to protect us from cosmic rays. Well, did you say the atmosphere was being "washed away", or didn't you? Make up your mind. http://www.ibex.swri.edu/ Yet another link that contains nothing immediately relevant to what you are claiming. -- David Barts Portland, OR |
