The new maps show that the large portion of the sky is filled with dark matter. It also shows that there is large amount of dark matter in some places and it is entirely absent in some places.
The galaxies are present where there is high concentration dark matter and where there is less dark matter the galaxies are also very less.
The map is produced from the data taken by the Dark Energy Survey. These maps are unveiled at the American Physical Society.
The new map aggress with the current theories which states that where is dark matter there will be galaxies as the gravitational pull of the dark matter will pull the galaxies towards itself.
The universe has five times more dark matter than the matter which can be seen, and the gravitational pull by the dark matter will influence how the galaxies are formed and evolved.
The study focuses on the smaller area of the sky.
The maps are highest resolution maps of this kind over such a large area which is 150 degrees square on the sky.
The maps point that even though the dark matter and the matter which can be seen are different but dark matter has strong pull on regular matter and determines how it is distributed in the universe.
Maps when zoomed will show how dark matter envelops galaxies and how they evolve together.
The data was taken from the Dark Energy Camera which is 750 megapixels.
The main aim of the Dark Energy Survey is to understand how dark energy is causing the universe to expand faster and faster.
Dark matter is invisible because it does not emit, radiate or block light.
Dark Energy Camera used the gravitational lensing phenomenon to develop those maps. Gravitational lensing is how the dark matter’s gravitational pull bends light from distant galaxies.
