From: Robert Elton Maas <REM @ MIT-MC> Suppose Betelguese goes supernova in the next century, bathing Earth with intense ultraviolet rays and other nasties. Suppose we have developed space sufficiently that we can put a protective barrier between Betelguese and Earth, blocking all direct radiation so we get only the charged particles that manage to swerve around our barracade.
