New breakthrough in dark matter search
October 23rd 2011 07:14
As we know, our stars, living things and planets are only 4% of our universe matter, and 21% of it is dark matter and rest called dark energy. Cold dark matter theory assumes most of the matter in the Universe cannot be observed by its electromagnetic radiation (dark) and whose constituent particles move slowly (cold). Cold dark matter theory describes how the universe went from Big Bang to current lumpy distribution of galaxies and their clusters we see today.
Dark matter everywhere
After study Dwarf galaxies around the Milky Way, Professor Carlos Frenk at Durham University, working with the Virgo Consortium, states:
"Our measurements contradict a basic prediction about the structure of cold dark matter in dwarf galaxies. Unless or until theorists can modify that prediction, cold dark matter is inconsistent with our observational data."
Using cold dark matter theory more small galaxies in a wide halo around the Milky Way are expected, whereas in reality there are fewer, larger dwarf galaxies.
Large Hadron Collider (LHC) at Geneva is working many years to search dark matter and Higgs. The result at Dwarf galaxies may mean that the Large Hadron Collider will not be able to spot it. We may not expect too much on LHC to discover new particles.

The answer to this question is at the cutting edge of science, but one theory states that dark matter is nothing but ordinary matter in another dimension hovering right above us.
