Particle Physics Revolutionizes Archaeology

How many mysteries are buried within Egypt’s Great Pyramid of Giza? Whatever the answer, we know of one more. Scientists recently discovered an unknown void in the heart of the pyramid. Over the past centuries, archaeologists have unveiled many features of the pyramid’s interior. If you get a tour today, you can venture along its Grand Gallery, into the king’s chamber, and touch the 4,500-year-old walls … Continue reading Particle Physics Revolutionizes Archaeology

Scientists observe light from antimatter for the first time

Physicists at CERN have observed the light emitted from antimatter for the first time, bringing us one step closer to unraveling one of the longest-standing problems in physics today – why is it that regular matter is so much more abundant than antimatter in the Universe? Standard models suggest that for every particle of matter created in the Big Bang, an antiparticle was also created. … Continue reading Scientists observe light from antimatter for the first time

New Physics from the AMS Experiment – Particle Physics on the International Space Station

In 2011 the Alpha Magnetic Spectrometer, or AMS, was launched into space. AMS, housed by the International Space Station and led by a Nobel Prize winning principle investigator, is commonly referred to as the most sophisticated particle physics experiment in space. The experiment was designed to study cosmic rays, a variety of high energy particles produced in space. In five years of operation, AMS has collected … Continue reading New Physics from the AMS Experiment – Particle Physics on the International Space Station

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

Dark Matter Evades the World’s Most Sensitive Search

At the 11th Identification of Dark Matter Conference, LUX, the Large Underground Xenon experiment, announced the results of the world’s most sensitive search for dark matter. Physicists at LUX have been racing for a dark matter discovery since the collaboration’s inception. Observers in the field were aware that the LUX announcement would include more data with vastly improved performance compared to experiment’s initial run in … Continue reading Dark Matter Evades the World’s Most Sensitive Search

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?
