Our galaxy heading for collision with Andromeda Galaxy
NASA states that nothing will happen to our Solar system. This is
absurd. The collision will commence after 2 billion years. By that time, Sun would have turned into a red dwarf star gobbling up all his planets. Even otherwise, solar system would perish in countless supernova explosions that follow the galaxy collision. Check out:http://signifies.net/our-galaxy-heading-for-an-end/ |

They could survive that, however, since the outer region of a red dwarf is so tenuous the planets could continue to orbit inside it. In any case, however, it is only the inner three planets at risk of destruction, and their absence will not change much in the Solar System. Even otherwise, solar system would perish in countless supernova explosions that follow the galaxy collision. When galaxies collide, regions of dust and gas that come together can form new star forming regions. High mass stars that form there will produce supernovas within just a few million years of their formation. But supernovas are only dangerous very locally, and mainly only to life. Since there will be no life on Earth when the galaxies collide, there will be nothing to be harmed by any local supernovas (and there may not even be any that are very close by). Certainly, we observe many colliding galaxies, and the vast bulk of both parents are not being affected by star forming regions. |

Some people think that it is possible that microscopic life--bacteria, in particular--living deep underground could survive the Sun's red-giant phase. With the atmosphere and all of the surface water boiled off, however, the chances of a new evolutionary cycle leading to the repopulation of the Earth by large animals or plants seems very unlikely. -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |

Bacteria certainly does seem resilient. Given the recent discoveries of bacteria living many kilometers below the surface, its survival during the Sun's red giant phase seems very possible. Of course, any life deep enough to survive will also be unaffected by even nearby supernovas. |

Check out:http://signifies.net/our-galaxy-heading-for-an-end/ Those unavoidable tidal interactions and the tossing of spare black holes about would due us in, even if nothing even came into direct contact with our world. Our red giant sun would likely advance to the helium flashover stage ahead of schedule, or simply implode from encountering significant other mass. Does anyone know if the encounter is going to be prograde or retrograde? http://groups.google.com/groups/search http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG, Guth Usenet/Guth Venus |

Exactly correct, in that life as we know it on this depleted planet is doomed to fail us billions of years before the galactic merger. We'd survive a whole lot better as within a nearly solid moon of a gas giant or brown dwarf. A partially hollowed out moon with an extremely thick and fused basalt crust of sufficient paramagnetic and/or carbonado property, would make for the ideal lifeboat that could best survive a galactic encounter. http://groups.google.com/groups/search http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG, Guth Usenet/Guth Venus |

Even otherwise, *solar system would perish in countless supernova explosions that follow the galaxy collision. Check out:http://signifies.net/our-galaxy-heading-for-an-end/ Sirius at 64 times brighter: Long before our galaxy gets nailed by Andromeda and we're getting ripped to shreds by black holes that start getting tossed about, at least our nighttime in a bluish-white plus UV starshine should become rather nicely illuminated, and better yet on every 50 year contribution of UV, X-rays and even gamma from Sirius(B) might actually contribute more gamma and X-rays than our moon. The most rich and powerful Oligarch Rothschilds (upper .0001% caste) as having never once complained about any GW or AGW issues, much less having been concerned about the availability or artificially inflated cost of energy, food, fresh water and health services, means that everything is exactly as artificially inflated and getting extra depleted as it should be. Don’t bother looking for any of those new or even lethal kinds of rogue/nomad asteroids, or even substantial planetoids headed our way, because we’re still not prepared to do anything except cringe and prey and/or sweat bullets, as we can only hope to hell that they somehow manage to keep missing us. http://www.msnbc.msn.com/id/47635708.../#.T8o2cNnvl7s Lots of talk and studies that’ll do nothing to prevent or divert the next encounter of the lethal asteroid kind of lithobraking trauma. Many of these new arrivals will not even be detected in time to notify those nearest its terrestrial impact zone, or from the radial downrange trauma of strong tidal forces that’ll follow as something dark, cold and scary of sufficient mass passes nearby. http://news.discovery.com/space/top-...eflection.html “If none of the nine aforementioned asteroid deflection methods pan out, there may not be much else to do if a near-Earth asteroid's course can't be altered with decades or even centuries of advance warning. So we may need to fall back on panicking.” With the Sirius Oort cloud directly upon us and closing in at 7.5 km/ sec; our recess time is about up. The Sirius Oort cloud should contain at least a thousand fold more asteroids and planetoids with considerably greater average mass than our Oort cloud of debris has to offer, and for the most part we’re still not prepared (physically nor mentally other than being really good at denial). As Sirius zooms past our solar system within a light year, is when it’ll get downright nasty for us, even though having that second sun may have some interesting illumination benefits with such a star being near 64 fold brighter than it currently is, whereas at least by then we’ll have become somewhat better able to identify those new asteroids and planetoids coming our way, and quite possibly prepared enough to either defend our planet or taking appropriate cover within our robust moon shouldn’t be unlikely. Even the planet Venus with its extremely thick and dense atmosphere could provide a better failsafe outcome than Earth, not to mention a little better shielded by the sun itself. http://groups.google.com/groups/search http://translate.google.com/# Brad Guth, Brad_Guth, Brad.Guth, BradGuth, BG, Guth Usenet/Guth Venus |

Check out:http://signifies.net/our-galaxy-heading-for-an-end/ A cosmic version of the HLC that started off with perhaps a combined 150 trillion solar masses that obviously contracted instead of galaxies having expanded away from one another. That’s a potential whopping 30 trillion solar masses (6e43 kg) each galaxy prior to the mergers that pretty much destroyed all life in all five galaxies. Supposedly 100 trillion solar masses is just the hydrogen and helium gas blown outside of these collided galaxies. http://www.dailygalaxy.com/my_weblog...milky-way.html In a few billion years, the Great Attractor with thousands of galactic mergers taking place (including whatever’s left of our galaxy), should put on quite a spectacular show.
