We all know that the visible part of the universe that is the stars, gases, planets and galaxies account for only one-sixth of the universe. The rest part of the universe is unseen.
The rest of the universe is all dark matter that does not emit or reflect light so we cannot see it. The dark matter has very high gravitational pull so it attracts the visible matter towards it.
Scientists have studied this matter for more than 1000 hours from the Hubble telescope and have stated that these are the best findings that can explain how the universe might have formed billions of years ago.
The researchers also stated that to reach us the light from these galaxies have to pass through this dark matter and the immense gravitational forces in these areas bend the light. Because of this bending all we see is a blurred image of the galaxy.
These recent maps from Hubble have confirmed that the dark matter is present in the forms of clumps of dark matter. After the ‘big bang’ the dark matter was separated from the main universe and that later collapsed under its own weight. This collapse led to the formation of clumps of dark matter.
All the galaxies in the universe are a part of some dark matter. Though this should always happen but many a times we also see dark matter clumps that are void of any galaxies. The scientists are also looking for the possible cause of this effect.
Till now no one is stating that the cosmological models have to be changed after these findings, but sooner or later we will have to redefine the universe and its formation after some more research has been done on these huge dark matter clumps.
