Andromeda, Galaxy The Greedy Approach

andromeda
Andromeda, large galaxies are known to be a neighbor of our galaxy is a cannibal space.
 Until now grow big like this, he has been eating other galaxies that flew too close to him. Interestingly, the Andromeda is now getting closer. 

As is known, Andromeda and our galaxy, the Milky Way, are the two giant galaxies in its environment. Andromeda is the nearest giant galaxy. The distance is only about 2.5 million light years. A light year alone is about 9.4 trillion miles.
As quoted by MSNBC, February 1, 2011, the Milky Way and Andromeda approaching each other with a speed of about 120 kilometers per second and will crash.
However, the long distance to make this giant new super collision will occur about 3 billion years to come. Then, whether the earth will be destroyed?
To find out, astronomers using supercomputer simulations and calculate one of the scenarios that may occur when Andromeda and the Milky Way collide with each other.
Video simulations are made using 100 million virtual particles. Movies made to highlight the room with wide viewing angle of about 10 billion billion miles. The duration of time recorded by a computer simulation was reached 1 billion years old.
"It is estimated, the stars in both galaxies, including the sun's solar system most likely will not collide with each other," said John Dubinski, an astronomer from the Canadian Institute for Theoretical Astrophysics, University of Toronto.
However, Dubinski said, the gravitational force of the two galaxies are likely to attract each other, mutual berpelintir, and deflect, until after a billion years later, elliptical galaxy that is a combination of Andromeda and the Milky Way was born.
After the merger of Andromeda and the Milky Way is completed, the process will leave the debris scattered in space.
As is known, before this, a small galaxy called Andromeda Triangulum swallow. About 3 billion years ago, Triangulum moving too close to the Andromeda.
