Discover the existence of dark material?
For the first time in history, physicists may have discovered an element of dark matter, a form of matter that accounts for 90% of the mass in the universe.

We cannot see dark matter but scientists recognize its existence due to the influence of the gravitational force it causes. Dark matter can help explain the lack of huge amounts of matter in the universe and explain the current rotation speed of galaxies.
Scientists have been looking for evidence of physical form just this hypothesis from the 1970s both in the earth and in space.

Some of the experiments have focused on finding weakly interacting large particles (WIMPs) that are thought to constitute dark matter.
If dark matter actually exists, then every second has a huge number of such particles passing through the earth. The difficulty is that they don't seem to have any interaction when moving.
One of the WIMP search experiments took place at the Soudan Underground Laboratory, half a mile deep beneath a mine in Minnesota, USA.
This depth helps protect sensors made from ultra-cold silicon and germanium from cosmic rays that still rush into the earth every day. These crystals are about the size of a hockey ball, which is expected to vibrate if there is a certain WIMP through.
The LHC machine is believed to recreate the Big Bang, which hopes to create dark matter particles.
This news was leaked from a physical blog, whereby scientists from the Cold Dark Material Research project (CDMS) will publish some important results in the next issue of Nature.
The prestigious scientific news site, New Scientist, also announced that quick discussions were scheduled on December 18 at the SLAC National Laboratory, University of California Santa Barbara and at Fermilab (the host partners weak with CDMS) about finding dark matter.
If the information about the discovery is inaccurate, the scientific community will have to look forward to the LHC particle accelerator in January 2010. LHC is expected to create conditions that exist right after the Big Bang (the big explosion that forms the universe), including dark matter elements.
