Astronomers compiled the most detailed 3D universe map

Astronomers at the University of Waterloo have compiled the universe map around us in 3D with the greatest detail ever. This map details how the basic materials distributed in the space range from 1 billion light-years away. This result will help scientists better understand the material distribution in the universe, especially dark matter, and explain why some spaces and galaxies are moving abnormally compared to the The apparent position of the Earth.

The most detailed 3D universe map today

Universe theory has shown that matter is uniformly distributed throughout the visible universe when it is viewed on a sufficiently large range. However, this does not mean that the density at each point in the universe is identical at the same time: if so, there are no galaxies, stars or planets we mentioned before. now. Instead, what we see are variations that occur not based on a predetermined model, which is influenced by the gravitational pull of ordinary matter and dark matter, forming clusters of galaxies. with position relative to us, depending on the direction of gravity.

Considering the overall universe, the fluctuations tend to be averaged, but in the space near the Earth, we are still witnessing significant fluctuations. Therefore, the team at the University of Waterloo led by Professor Mike Hudson created the most comprehensive map of the universe, describing the distribution of galaxies in all directions with different ranges. up to 1 billion light years . This is truly an amazing range compared to our Milky Way galaxy, which is only about 100,000 light-years across.

The map reveals the random fluctuations of galaxies in the universe

As expected, the map revealed random fluctuations, not following a predetermined model of galaxies throughout the universe. As can be seen in illustrated images and videos, the red and white areas take place in areas where many galaxies are concentrated, while low-density areas are represented by dark blue. In particular, the small red area is the Shapley Galaxy Super Cluster , a collection of the largest galaxies about 650 million light-years away.

On the other hand, the map also gives astronomers a better insight into the characteristic velocities of galaxies near us - part of the relative movements of galaxies in a single universe. most are expanding, which has not been explained before. With this map, scientists can conclude that the cause of these movements is due to the difference in density between ordinary matter and dark matter. Professor Hudson and the team believe that by using these data, they can get an overview of the claims of dark matter throughout the universe. In order to do that, they will continue to study to determine the exact speed of each universe and enhance the resolution of the map.
