The best dark matter map to date raises questions about the universe.



Scientists in the Dark Energy Survey just released the best dark matter map. But it still doesn’t answer every question — if anything, the universe might be more mysterious than ever. BBC News, nature and the Fermilab report, a survey of 5,000 square degrees uses soft gravitational lenses (in this case, how gravity from nearby galaxies affects the view of distant galaxies) to search for massive dark matter. in a relatively close part of the universe

This information also helps to study dark energy. This is an unexplained force that appears to be accelerating the expansion of the universe. The team created a 3D map with a red color change. or the tendency of objects to appear more red with distance.

Team members made observations using the Victor M. Blanco Telescope̵

Although high detail is helpful. But it has investigated concerns that have been floating for years. The DES results indicate that the universe is slightly smoother and more consistent than expected. Although this supports the current theory that dark energy is largely constant. But the discrepancy is enough that researchers may have to rethink existing ideas. The universe may not look like scientists think. And dark matter maps may lead to new models that defy previous hypotheses.
