A scientist at the Large Hadron Collider. Particles travel round the circuit significantly faster
Keystone
Scientists at the European Organization for Nuclear Research (CERN) have restarted their Large Hadron Collider (LHC) “Big Bang” machine after a two-year refit, launching a new bid to resolve some of the mysteries of the universe.

In a live blogExternal link covering the restart, CERN said on Sunday that one of the two beams had completed the 27km circuit of the LHC, beneath the Swiss-French border near Geneva.
The LHC had been shut down for two years for a refit of its machinery and wiring. CERN spent about $150 million (CHF144 million) on the upgrade, opening the massive machine every 20 metres, checking magnets and improving connections.
Any new discoveries it makes are unlikely to emerge until mid-2016. Scientists are promising nearly twice the energy and more violent particle crashes this time around. They hope the more powerful beam crashes – expected to start as early as June – will give them a peek into the unseen dark universe.
The collider was instrumental in the discovery of the Higgs boson, a subatomic particle that had long been theorised but never confirmed until 2013.

An experiment using the Large Hadron Collider at CERN (the European Organization for Nuclear Research) found the new particles, which were predicted to exist, and are both baryons made from three quarks (elementary particles) bound together by a strong force. In a statement on Wednesday, CERN officials said the discovery could shed more light on…

The LHC is the world’s largest and most powerful particle accelerator. First started up on September 10, 2008, it consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the…
