Scientists 'find signs' of the Higgs boson.

Summary: Scientists say they have found signs of the Higgs boson while conducting tests at the Large Hadron Collider near Geneva.

Scientists say they have found signs of the Higgs boson while conducting tests at the Large Hadron Collider (LHC) on the French-Swiss border near Geneva.

Researchers at the LHC revealed the details at a packed press conference on Tuesday which was streamed live on the internet.

The search for the Higgs boson has been taking place near Geneva in a 27-kilometre circular tunnel 100 metres below the ground.

It is dubbed the "Big Bang machine" because scientists reckon it can recreate conditions a fraction of a second after the birth of the universe.

The machine has been built as a cost of Au2.6 billion and weighs more than 38,000 tonnes.

It accelerates the streams of protons - the "hearts" of atoms - close to the speed of light and smashes them into each at unprecedented energies.

Two experients at the LHC, called ATLAS and CMS, have caused the current frenzy of excitement, although, researchers admitted in May it could be two years before they can establish whether the Higgs Boson actually exists or not.

However, a discovery that nature contains a Higgs particle would be a momentous event in physics. Scientists might have to abandon the "Standard Model", the best theory so far for explaining the fundamental mechanics of the universe.
