Astronomers who are in search of the elusive dark matter could be finally nearing their goal. A signal which scientists say could be the first physical evidence about the existence of Dark Matter. If this postulate is confirmed it will become the first tangible evidence of dark matter.
Astronomers could have detected finally a signal pertaining to dark matter, the stuff which makes up much of the material universe. Researchers associated with the European Space Agency have stated that they have detected a spike in the X-Rays coming from two locations, the Andromeda Galaxy and the Perseus Cluster. The researchers are of the opinion that the strange emissions could be the signal of dark matter. If the above assumption is proved true , it will be the first direct evidence of dark matter.
Scientists at the European Space Agency’s XMM-Newton spacecraft, scientists at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland were examining loads of X-ray data and found a strange spike in X-ray emissions which are coming from two different regions — the Andromeda galaxy and the Perseus galaxy cluster. Since the signals did not correspond to any known particle or atom, scientists are no speculating if it could have been produced by dark matter.
Oleg Ruchayskiy of EPFL, and a co-author of the study scheduled to be published in the journal Physical Review Letters, said in a statement, “The signal’s distribution within the galaxy corresponds exactly to what we were expecting with dark matter, that is, concentrated and intense in the center of objects and weaker and diffuse on the edges.”
Scientists opine that visible matter is not adequate to explain rotation of objects and the existing gravitational forces in the cosmos. Without the presence of any specific factor which holds these galaxies together, they would have torn themselves apart millions of years ago.
According to the EPFL statement, “There is something missing. From this (the scientists) deduced that there must be an invisible kind of matter that does not interact with light, but does, as a whole, interact by means of the gravitational force.”
Alexey Boyarsky of EPFL and the study’s lead author said in the statement, “Confirmation of this discovery may lead to construction of new telescopes specially designed for studying the signals from dark matter particles. We will know where to look in order to trace dark structures in space and will be able to reconstruct how the Universe has formed.”
If indeed this is the discovery of the existence of Black Matter, which constitutes 80% of the cosmos, it will usher in a completely new era of particle physics and astronomy.cost of cialis at cvs
