  High energy particles are produced by the annihilation of dark matter
particles in our galaxy. These are presently searched for using balloon-borne
antiproton and positron detectors and large area, deep underground neutrino
telescopes. Dark matter particles, trapped inside the sun, are an abundant
source of such neutrinos.
  From both the cosmological and particle physics points of view the lightest,
stable supersymmetric particle or neutralino is arguably the leading dark
matter candidate. Its mass is bracketed by a minimum value of order a few tens
of GeV, determined from unsuccessful accelerator searches, and a maximum value
of order 1~TeV imposed by particle physics as well as cosmological constraints.
Back-of-the-envelope calculations are sufficient to demonstrate how present
neutrino telescopes are competitive with existing and future particle colliders
such as the LHC in the search for supersymmetry. We emphasize that a $1\,\rm
km^2$ area is the natural scale for a future instrument capable of probing the
full GeV--TeV neutralino mass range by searching for high energy neutrinos
produced by their annihilation in the sun.
