According to foreign media reported that our Galaxy is in open space boundaries, it’s such a huge and difficult to describe. In order to better understand its shape and size, a team of astronomers has drawn up this open space, and the calculated its Galaxy’s gravitational effect. Just as the earth revolves around the sun and go and run the Sun around the galactic center public go, our galaxy itself at a very fast speed through the Universe. The Milky Way and near neighbors such as fairies galaxies and a series of smaller galaxies, at a speed of approximately 200 million km/h (130 million mph) speed high-speed mobile.
Such differences can in large measure the quality distribution to explain.
Galaxies are not evenly distributed throughout the Universe – they tend to come into a galactic mission, through the fine filaments” materials such as a spider’s web. This makes the most of the space relatively empty – as astronomers found in 1987, Galaxy is located right in the heart of one of the edges. It is well known that the so-called local empty local void) is located in the heart of the Galaxy group, next to the almost empty Space appears to be becoming more and more. A few years ago, astronomers found that is known as a dipole repeller in low-density areas are driving the Galaxy and the Galaxy wall local sheet) in other galaxies – this is a nearly flat galaxy to form a hole in the wall.
However, it is very difficult to study the local empty. For this study, the team has measured a cosmic flows-3 data set, which contains a detailed description of the 18,000 galaxies. With this in mind, researchers built a 3D map of the universe, found that the local empty “wall” has become the focus. The team also uses this information to calculate the local empty of our Galaxy to the gravitational effect. Taking into account the expansion of the universe, the expected speed, researchers found that our galaxy in approximately half of the campaign is “local”, because of the enormous room of the galaxies in a milky way toward it and the local empty the galaxy “eviction”. This new study published in the Journal of astrophysics. The team in the following video provides details on the use of a local empty 3D model of the shape and structure.
