Scientists within the Darkish Power Survey have simply launched one of the best darkish matter map but, nevertheless it’s not answering each query — if something, the cosmos could also be extra mysterious than ever. As BBC Information, Nature and Fermilab report, the survey of 5,000 sq. levels used weak gravitational lensing (on this case, how gravity from close by galaxies impacts views of distant ones) to search for massive patches of darkish matter in comparatively shut sections of the universe.
The information additionally helped research into darkish vitality, the as but unexplained pressure that appears to be accelerating the universe’s growth. The staff produced a 3D map because of redshifting, or the tendency of objects to look more and more pink with distance.
Workforce members carried out observations utilizing the 570-megapixel digital camera of the Victor M. Blanco telescope, at Chile’s Cerro Tololo observatory, between 2013 and 2019.
Whereas the excessive element is useful, it additionally validated issues which have been floating for years. The DES outcomes point out that the universe is barely smoother and extra uniform than anticipated. Whereas that largely helps present theories that darkish vitality is a continuing, the discrepancy is sufficient that researchers may need to rethink current concepts. The universe might not behave fairly like scientists thought, and the darkish matter map may result in new fashions that problem earlier assumptions.
