The Milky Way, or Milky Way, is a spiral galaxy of which the solar system is part, this galaxy, seen from the planet Earth, appears as a small, bright and diffuse band that surrounds the entire celestial sphere, cut by molecular clouds that give it an irregular and cropped aspect. Its visibility is greatly compromised by light pollution, but with few exceptions, all objects visible to the naked eye belong to this galaxy.
Research indicates that our galaxy, the Milky Way, is currently being attracted to a region rich in galaxy, a fact already known by scientists. However, the Milky Way may also be being pushed by an invisible force.
The galaxy is being pushed into the universe by an invisible force, a study published in Nature suggests. And it is this force that allows our galaxy to travel and accompany the expanding universe. This theory explains why the Milky Way has moved at a relatively high velocity, a behavior that scientists had already observed about 30 years ago: “We find an emptiness exactly in the opposite direction” to that of galaxy motion, which Suggests “a push toward a lack of attraction”, Brent Tully, one of the authors of the study, told the BBC.
Scientists have long believed that the Milky Way is being drawn into an area rich in galaxies some 750 million light-years away. In this area, astronomers call it Shapley Concentration. Yet, even though the galaxies are moving away from each other because of the expansion of space, they are attracted by the force of gravity. These attractions “cause deviant movements,” which lead them more likely to high-density regions than to low-density regions.
In this particular case of the Milky Way, astronomers believe that it is not only being pulled into that region (an attraction they have been able to observe through three-dimensional models with the help of telescopes), but it is also receiving a “push” from of their “backs.”
