Scientists sense breakthroughs in dark-matter enigma

Knowing the enigmatic dark-matter in the universe finally seems possible, as cosmologists have claimed that soon the unknown force that drives the expansion of the universe, will be unveiled.

For decades, the strange substance called dark matter has teased physicists, challenging conventional notions of the cosmos.

Today, though, scientists believe that with the help of multi-billion-dollar tools, they are closer than ever to piercing the mystery -- and the first clues may be unveiled just weeks from now.

"We are so excited because we believe we are on the threshold of a major discovery," said Michael Turner, director of the Kavli Institute for Cosmological Physics at the University of Chicago, at an annual conference of the American Association for the Advancement of Science (AAAS).

Dark matter throws down the gauntlet to the so-called Standard Model of physics.

Elegant and useful for identifying the stable of particles and forces that regulate our daily life, the Standard Model only tells part of the cosmic story.
