Scientists Create First Dark Matter Map
A hypothetical matter which makes up the universe but still cannot be seen – Dark matter is a subject of profound interest for all scientists. A map has been released which shows dark matter present in the cosmos, highlighting the importance of its existence.
Scientists researching on dark matter are of the view that it is composed of such particles that do not reflect, emit or absorb light. Further properties tell even with electromagnetic radiation cannot lead us to the dark matter, being not visible directly. But then again what is it that gives scientists so much room to think.
It is because, they say, of the way it affects other entities in the universe. Nevertheless comprehending dark matter specifics to a great detail stills remains a great challenge.
the Dark Energy Survey (DES) that released the dark matter map suggests the development of this map is a significant break in unraveling the mystery behind dark matter. Chihway Chang of the Swiss Federal Institute of Technology in Zurich is confident that his map will assist scientists, in great detail, in learning how galaxies evolve.
“Our analysis so far is in line with what the current picture of the universe predicts,” says Chang. “Zooming into the maps, we have measured how dark matter envelops galaxies of different types and how together they evolve over cosmic time. We are eager to use the new data coming in to make much stricter tests of theoretical models.”
Scientists also believe that it is the invisible form Dark Matter which is responsible for holding the galaxies together. Work needs to be done so that the real working and existence of such invisible dark matter be known and understood.
It is only 2 years of efforts that DES has been able to cover in document only 3% of the sky area, and with persistent research effort scientists are likely to make more detailed observations and test the existing cosmological theories.
