-The LHC was powered up on 10 September 2008, with the first beams being circulated through the collider. It reached full power in mid-November 2008, which is when scientists were supposed to begin smashing [[particle]]s into each other. This was hampered however as the LHC suffered a mechanical breakdown just as it was switched on and it was not active again until early 2010.  Numerous major problems have emerged and it may take years before the machine is fully operational.<ref>See [https://www.nytimes.com/2009/08/04/science/earth/04collide.html?ref=world "Giant Particle Collider Fizzles," Dennis Overbye ''New York Times'' Aug. 3, 2009]</ref>
