Something is wrong with dark matter

Photos: Secrets of the 'God particle'
Studying the 'God particle' – Three years ago, scientists in Geneva, Switzerland, announced they had proved the existence of the so-called "God particle" known as Higgs boson -- a never-before-seen subatomic particle long thought to be a fundamental building block of the universe. This year, researchers from two different teams combined their measurements of the particle, providing an unprecedented picture of Higgs boson's production, decay and interaction with other particles.

This graphic shows traces of the collision of particles from an experiment at the Compact Muon Solenoid (CMS) -- a large particle detector in Geneva. The Standard Model of particle physics lays out the basics of how elementary particles and forces interact in the universe. But the theory crucially fails to explain how particles actually get their mass. Particles, or bits of matter, range in size and can be larger or smaller than atoms. Electrons, protons and neutrons, for instance, are the subatomic particles that make up an atom. Scientists believe that the Higgs boson is the particle that gives all matter its mass.

"Only now with the LHC [Large Hadron Collider] are we able to really tick that box off and say 'This is how the universe works, or at least we think it does'."](http://cdn.cnn.com/cnnnext/dam/assets/131205161618-02-cern-hp-video.jpg)

Studying the 'God particle' – Higgs boson research takes place at the Large Hadron Collider -- a circular tunnel located 100 meters (328 feet) underground. It uses a particle accelerator to collide protons at extreme speeds. By combining their data, researchers found that there are different ways to produce a Higgs boson, and different ways for a Higgs boson to decay to other particles.
