HIGH-ENERGY PHYSICS:
Report Backs Collider and an Expanded Field
Charles Seife
U.S. high-energy physicists want to redefine their field to include the entire cosmos. But they also have a very down-to-earth proposal for the government to back their next multibillion-dollar machine: the Next Linear Collider, which will smash electrons and antielectrons together at about half a trillion electron volts of energy and cost between $5 billion and $7 billion.
