New Experiment Chases the Elusive Magnetic Monopole

A new experiment at the Large Hadron Collider (LHC) seeks to detect the long theorized magnetic monopole. In 1931, physicist Paul Dirac showed that our theories of electromagnetism allow for the existence of a solitary magnetic charge. Just as protons and electrons represent unique electric charges (positive and negative), magnetic monopoles should similarly exist as manifestations of magnetic charge. Despite our best efforts, however, we … Continue reading New Experiment Chases the Elusive Magnetic Monopole

The long awaited and much debated discovery of the pentaquark

A few weeks ago, the LHCb, an experiment at the Large Hadron Collider, announced the discovery of a new particle, the pentaquark. What is a pentaquark? Well…it’s a particle, that’s made of five quarks. A quark is one of the smallest fundamental building blocks of matter. Quarks have not been observed alone in nature, and are only known to exist as composite particles. Most commonly, … Continue reading The long awaited and much debated discovery of the pentaquark

Didn’t the LHC restart in April?

This April, SITN Waves, along with many other news outlets, reported on the restart of the Large Hadron Collider, or the LHC. Many similar headlines were seen last week when CERN announced the machine’s official restart. So when did the LHC actually restart, and what were scientists at CERN doing in the meantime? On April 5, the LHC was powered on for the first time … Continue reading Didn’t the LHC restart in April?
