Scientists don’t know exactly what to expect from powerful collider

Squarks, photinos, selectrons, neutralinos. These are just a few types of supersymmetric particles, a special brand of particle that may be created when the world's most powerful atom smasher goes online this spring.

The Large Hadron Collider, under construction at the French-Swiss border at a particle physics lab called the European Organization for Nuclear Research (which is better known by its French acronym, CERN), will very likely change our understanding of the universe forever.
