For each of these areas I inquire how that reach is, or might be, extended by experimental and observational astrophysics and astronomy. The five areas are: searches for particles with very large masses and measuring those masses, searches for particles with very small masses and measuring those masses, searches for new types of particles, searches for unexpected behavior of the known forces or for new forces and searches for new phenomena at very high energies.Presented at the Cosmic Genesis and Fundamental Physics Workshop, October, 1999High Energy Physics - Experimenttext
