How will die the milky Way?
The earth has existed for one billion years, it`s a lot, but if you roughly calculate how much is still left to live, there are not many, scientists believe that about a couple billion years the Sun will expand to a huge red giant and burn all life on Earth. Further, the Ground charred and sterile will continue flying around is not a big a white dwarf, which will not be able to maintain the heat on the planet and the Earth will begin the era of cold oblivion. At the same time in our galaxy, some stars will be extinguished, and others to illuminate where the planets will burn, and where to begin their March along the evolutionary ladder.
Clear yet one, our galaxy will live longer than 2 billion years, but it at some stage will sink into oblivion. First, the milky way will fade, and later completely disappears.
About how it`s all going to happen we decided to dream!
Near our milky way galaxy there are several galaxy of Andromeda, the Magellanic clouds. When will our galaxy to die, what will happen to them There are a number of and galaxy Triangle, it`s the weight of stars is about 95% lighter than our galactic home. Galaxy Triangle revolves around the Andromeda galaxy, also in its orbit around the star clusters of the Triangle rotate the smaller stellar objects.
Our galaxy has satellites and their two Magellanic clouds, the large cloud weighs only 1% of the mass of the stars in our galaxy. Straight to the Magellanic clouds some 200 thousand light-years. It`s not much, if you know that the milky way across more than 100 thousand light years. The Large Magellanic cloud galaxy scientists call a stellar nursery, there comes a lot of new stars. The small Magellanic cloud is even less wide and weight is approximately equal to 0.1 of the mass of stars in the milky Way galaxy.
Around our galaxy at roughly "not far" consists of about 45 large galaxies, all of these star clusters constitute our group of galaxies. Between each galaxy and nearby there is a gravity connection, the visible stars are separated by layers of dense dark matter that separates one galaxy from another. The laws of physics larger galaxy mass affects smaller as the total weight and in parts. At the next star is affected by stronger gravity, and at a far smaller and in the end it turns out that larger galaxies eventually tear, resolves small cluster of stars. It turns out that at least our galaxy is in the end, the Magellanic clouds will be torn to pieces and the substance formed when these clusters become part of a larger galaxy.
Later, two of the milky Way galaxy and the Andromeda Nebula will start rotating around one another, this will happen in about 4 billion years, while both the galaxy at great speed, flying to meet each other. After a mutual dance, the two galaxies will merge into a single star constellation.
Scientists of the future will clearly call her Malcantone, in its composition are all small galaxies of our group, this is a new and very large star cluster. Then everything goes in the same scenario as before, until the star is, while the gas is, and will continue to grow and die, stars, and the galaxy will live. Over time, stars will be born less and less, and their dead bodies will be more and more. Even when the last star in this galaxy, United will burn, the galaxy hundreds of trillions of years will Shine in the sky of gradually cooling down.
In the center of the galaxy Mikeandrose will be formed just a huge black hole, its mass will be equal to 100 million times the mass of our Sun. At some stage of evolution if we are not deceived Hawking and the black hole will die, too. What will remain, after all uzhmetsya into a black hole and that in turn by itself will evaporate in 10 ^ 100 years Neither of which will not only be dark matter, which eventually dissolves and also from milky way and surrounding galaxies will only "puff"..
