Conclusions of the last research say that a half (that it is much bigger, than it was supposed in earlier researches) matters of the Milky Way, including atoms of which all of us consist, could come because of borders of our galaxy here. Such conclusions were drawn on the basis of the simulations which are carried out by means of supercomputers. Thanks to it scientists could define the new phenomenon nicknamed intergalactic transfer. And it, according to researchers, can help us to open secrets of development of galaxies.

"Turns out that we not such and "local". This research gives us an idea of how remote objects in the sky", & #8212 can be among themselves connected; Foshe-Zhige notes.

Galaxies represent a big congestion of the stars connected among themselves by a gravitational attraction of a uniform source of weight which role is played, as a rule, by the supermassive black holes which are directly in their "center"s. However almost right after the Big Bang nearly 14 billion years ago no stars and galaxies existed. The space was filled only with uniform gas.

Larger galaxies initially had a large supply of matter. Besides, it is more difficult to matter which got to them from other sources to leave such galaxies. Scientists knew that matter can pass from some galaxies into others long ago. Only a scale and possible volume of this matter was unknown. And according to a new research, atoms of matter of big galaxies as that in which we live can originate for millions of light years from them.

"This research changes our understanding how galaxies were formed after the Big Bang", & #8212; Claude-Andra Foshe-Zhige, one of researchers speaks.

Despite opinion that these intergalactic winds were very fast - perhaps with a speed in several hundreds of kilometers per second - the huge distances dividing galaxies allowed atoms to get over from one galaxy in another only later billions of years.

"Considering how many matter of which we consist, could come from other galaxies, we can consider surely ourselves space travelers or intergalactic immigrants", & #8212; the leading researcher of the project Daniel Angles-Alkasar said.

The modeling which was carried out by the team of astrophysicists from Northwestern University showed that explosions of supernew are capable to throw out the large volume of gas out of borders of those galaxies in which they are. At the same time atoms of this matter are transferred from one galaxy to another by means of powerful galactic winds.

Easy changes in streams of this gas and a gravitational pool finally led to formation of the first stars, congestions and, eventually, galaxies. The new research, according to scientists, gives a new view on understanding of process of galactic formation.

Using the simulyatsionny FIRE system (Feedback In Realistic Environments), researchers could create realistic 3D models of evolution of galaxies from the moment of the Big Bang and about one today. Then scientists used special algorithms for data processing about matter which galaxies could absorb in themselves from other sources. It turned out that huge volumes of gas flowed from small galaxies in larger as our Milky Way.

"Possibly, a considerable part of matter of the Milky Way initially belonged to other galaxies, and then was thrown out from them by powerful winds thanks to which it crossed intergalactic space and at last found the new house in our galaxy".
