On 5th April 2015, scientists at the European Organization for Nuclear Research (CERN) shot two particle beams through the Large Hadron Collider’s 27km tunnel, beneath the Swiss French border.
The world’s biggest particle accelerator is back in action after a two-year shutdown, embarking on a new mission that scientists hope could give them a look into the unseen dark universe. Dark matter – and its cousin, dark energy – make up most of the universe, but scientists haven’t been able to see them yet, so researchers are looking for them in high-energy crashes, in orbit in a special experiment on the international space station, and in a deep underground mine. Scientists are promising nearly twice the energy and more violent particle crashes this time, starting in June 2015.
