After this passage, the two galaxies will swing by each other again more quickly, about 3.5 billion years from now, and will finally merge into a single blob some 5 billion years from now, Cox and Loeb say.PDF Cuando Eramos Soldados. Many of the stars will be gravitationally perturbed by the collision - some may even be ripped from one Galaxy and take up residence in the other. Over a period of half a million years, the two galaxies will pass through each other, with individual stars passing through the gaps (the chances that two stars might collide are very slim). Cox and Loeb conclude that the next close passage will occur in less than 2 billion years. The added mass of the haloes makes the Milky Way and Andromeda galaxies more gravitationally attractive and this speeds up the merger process. But that calculation was made in the days before it was realized that all galaxies are immersed in extended, massive dark-matter haloes. In 1959, it was determined using Kepler's laws of motion that both galaxies had traced out almost a full period of their orbital motion and were falling back together, with the next close passage occurring about 4 billion years from now. They are approaching each other at 120 kilometres per second, but there is a great gulf of more than 2 million light years between them. 'But I guess these guys have decided to take the plunge.' Collision course It has long been known that Andromeda and the Milky Way will eventually merge, although it won't happen for a long while yet. 'I never thought there was enough detailed information about the nature of the structure and dynamics of the Milky Way-Andromeda pair to write a full-blown scientific paper about the future of the Sun,' he says. John Dubinksi, an astrophysicist at the University of Toronto in Canada has explored this scenario before using models and animations. Some astronomers, however, think it may be a little premature to start predicting the fate of these galaxies, and particularly the Sun.

Es la mejor narracion de un combate de infanteria que haya leido jamas, y el libro mas importante de cuantos se han publicado sobre la Guerra de Vietnam." –CORONEL DAVID HACKWORTH "Cuando eramos soldados y jovenes es un gran libro de historia. "Una historia epica e impactante salvaje, visceral y de gran crudeza visual. 'We are the first to do a comprehensive numerical simulation that examines the detailed dynamics of the Milky Way and Andromeda, including the gas, dark matter and stars,' says Loeb. Loeb says he and Cox factored in new data about Andromeda's motion in space as well as the expected contributions of dark matter to galactic movement.
Using a sophisticated program for cosmological simulations known as GADGET-2, Loeb and colleague Thomas Cox modelled the future encounter to an unprecedented degree. Although this will be tens of millions of lifetimes from now, it is conceivable that humans may still exist when the two galaxies finally meet. 'The merger will take place before the Sun burns out, so that future astronomers within the Solar System can witness it,' says Abraham Loeb of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. There's a good chance that it will be flung towards the outer edge of our galaxy, researchers say, and a tiny chance that it will be 'kidnapped' by Andromeda.
The earlier date means that the Sun will still be alive when the two collide and a new computer simulation shows what could happen to our star. Harvard-Smithsonian Center for Astrophysics Our Milky Way galaxy is headed for a sedate collision with its neighbour, the Andromeda galaxy, billions of years earlier than was previously thought.
