The CERN research center has had to postpone the re-launch of their refitted ‘Big Bang’ machine.

The Large Hadron Collider exposed a short circuit in its wiring of one of the vital magnets. The center’s general director assured the public that the setback was minor in the big scheme of the project, according to Reuters.

The engineers had intended to start pumping proton beams in opposite directions all the way around the 17-mile underground of tubes in LHC on Wednesday, until the short circuit was found. This plan was the prelude to the start of particle collisions scheduled in late May at twice the power of those in the first run from 2010-2013.

This smashing together of particles inside the LHC is meant to mimic the circumstances that came just after the Big Bang at the beginning of the universe. This development came in 2012 when CERN scientists declared the detection of a new subatomic particle, a basic building block of the universe.

The hope of this second run is to breakout of what is known as the Standard Model of how the universe works at the level of elementary particles and move into “New Physics.” This proposal would also include the search for the dark matter that makes up about 96 percent of the stuff of the universe, but can only be identified by its influence on visible matter around it.

Although disappointed, CERN scientists insist that there can be no rushing into full operations. Wary from a series of leakage in 2008 which caused a two-year delay in the start-up for the first LHC run, engineers are thoroughly repairing the cause of the set-back of this run.

The problem is thought to be corrected relatively quickly. The intermittent short-circuit was in a cold section of the machine which means that part would have to be warmed up and then re-cooled, which could take a few weeks.
