CERN Large Hadron Collider to Restart Late 2009
Damage to CERN's Large Hadron Collider from the mishap shortly after it opened in September, 2008 required extensive repairs. The LHC will restart in late 2009. more...
What Happened to the CERN Large Hadron Collider
Shortly after the CERN Large Hadron Collider accelerated its first protons, an accidental liquid He leak caused some magnets to warm up and necessitated repairs. more...
Understanding Bosons and Fermions
The Higgs boson, aka the god particle, which physicists hope to detect with the new LHC, is the holy grail of modern particle physics. What are bosons and fermions? more...
Leptons are a class of elementary subatomic particles, which includes electrons and neutrinos, that interact via the weak nuclear force. more...
Protons and other types of hadrons interact via the strong nuclear force. Hadrons are further classified into mesons and baryons. more...
Can the CERN LHC Destroy Earth?
A calculation of the total energy density produced by protons in the Large Hadron Collider at CERN shows it is not likely to destroy Earth. more...
Light and all types of subatomic elementary particle show properties of both waves and particles. more...

A New Experiment in the Hunt for Neutrinos
By: Jeremy Small
Those hunting for the elusive neutrino typically trek to exotic locations to detect the particle. But new projects are looking up to Moon to detect neutrinos using radio. more...
Are Scientists Closing in on the Higgs Boson?
By: Jeremy Small
Scientists with the Fermi National Accelerator Laboratory say their machine has a 50% chance of discovering the particle which is believed to give mass to the universe. more...

The four known natural forces are, from strongest to weakest: strong nuclear, electromagnetic, weak nuclear, and gravity. Without forces structure could not exist. more...
Tevatron Racing LHC to the Finish
By: Mike Perricone
Fermilab's Tevatron is trying to make more scientific news before Europe's huge Large Hadron Collider completes repairs and begins operations again in the Spring of 2009. more...

Proton collisions, at near light speeds, lead to bizarre effects which seemingly defy common sense. Einstein's Theory of Special Relativity helps to make sense of it all. more...
World's Biggest Gun Set to Fire September 2008
By: Bobby Brown
Straddling the Franco-Swiss border near Geneva, 50 meters underground and an astonishing 17 miles long; the Large Hadron Collider (LHC) is easily the World's biggest gun. more...
