Not seen, felt
Researchers believe that the material left behind the LMC has not just stars but also something else that is not visible. They believe it may be dark matter. It is believed that much of the universe is formed by dark matter and it can only be observed by the effect of gravity, not directly seen. The study’s co-author, University of Arizona doctor student Nicolas Garavito Camargo, says it could be Dark Matter taking stars with him.
Question on dark matter?
Stars and planets do not flow in space even after the galaxy rotates under the influence of dark matter. Researchers hope that Dark Matter can also be understood by studying it. Astronomy Professor Charlie Conroy of Harvard University says that it is like walking a boat. He says that moving a boat can be understood based on the path behind it whether the boat is moving in water or in honey. On this basis, one can try to understand the dark matter.
When will there be a collision?
Based on the new map and the model created by other researchers, the team is working to prove the theory of Dark Matter. The map has been prepared based on data from the telescope of the US Space Agency NASA and the European Space Agency ESA. This also shows that this galaxy is moving slowly towards the galaxy and its orbit is decreasing. It will collide with the Milky Way 2 billion years later. The merger of two galaxies is a common phenomenon in the universe. The galaxy collided with a small galaxy even 8 billion years ago.
