The Unexplained Mysteries of Dark Matter

Nobody knows what exactly the Dark Matter is! However now, scientists might be able to have a clue what they need to do or where they need to look, if they wanted to conduct a research on it.

It is invisible and you cannot identify its presence in the universe. However, researchers know that it's there, as you cannot find appropriate regular matter, in the form of stars, planets, dust and gas, for holding galaxies and the clusters of galaxy together. Some type of invisible (unseen) material, which can be dubbed as dark matter, has to be there that is making them glued to one another.

So How Will You Find Something That Is Not Visible To Your Senses?
A new computer imitation of the evolution of galaxy (similar to our Milky Way) is suggesting that it might is possible for observing high-energy gamma rays, which are given off by these dark matters.

Simon White, who is the Director of Max Planck Institute for Astrophysics, has said, ‘The calculations brought about by the computer imitation finally has allowed us to come to a conclusion what the Dark Matter distribution can look like, when it is in vicinity of the Sun. There, we might have a chance to detect it.’

White is a member of the International Virgo Consortium. This consortium of Durham University is a team of scientists, which also include cosmologists. The findings of this consortium have been given in details the November 6 2008 issue of ‘Nature’.

Previous studies on the issue have given an indication that Dark Matter played a crucial role in the galaxy formation. According to the studies, it was also revealed that this mystery material still continues to hang around in halos surrounding galaxies.

The new computer simulation observed how dark matter halos could have evolved and behaved. The halo of virtual galaxy grew through series of violent mergers and collisions in between smaller clumps of dark matter, which emerged from Big Bang Theory (Theoretical beginning of our Universe).

The computer simulation revealed that gamma-rays, which are produced when particles had collisions in areas having high density of dark matter, could be easily detected when they were present in areas of Milky Way that was close to the Sun.

Carlos Frank, who is the director of the Institute for Computational Cosmology of Durham University, feels that ‘Search for this dark matter has been dominating cosmology for several decades now and its high time that we should do something concrete in this regard’.

Scientists researching in Durham University and other top institutions have figured out that Fermi Telescope of NASA should search in this area of the galaxy. It is the only available instrument in the Universe that can discover the signature glow of this dark matter.

Let us see, how long does it take for the top scientists in the world to uncover this truth and how much in depth they can go!
