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.
