SUMMARY:Mysteries of the High-Energy Sky\, NPAC (Nuclear/Particle/Astr
 o/Cosmo) Forum\, Dan Hooper\, Fermilab
DESCRIPTION:It has been more than a century since the discovery of cos
 mic rays\, and yet there remains much that we do not know about these 
 mysterious particles. In particular\, it is an open question as to whe
 re many of the cosmic rays come from and how they are accelerated to s
 uch incredible energies. The resolution to these puzzles will require 
 not only measurements of the cosmic rays themselves\, but also informa
 tion provided by gamma-ray\, X-ray\, optical\, infrared\, and radio te
 lescopes\, gravitational wave detectors\, and high-energy neutrino tel
 escopes. It will be through this program of multi-messenger astronomy 
 that we will finally be able to identify the sources of the cosmic ray
 s and cosmic neutrinos\, and begin to understand the physics behind th
 ese naturally occurring engines of high-energy particle acceleration. 
 This observational program will also provide exciting opportunities fo
 r the field of particle physics\, allowing us to test a variety of new
  physics scenarios\, to search for the particle nature of dark matter\
 , and to further probe the physics of neutrino oscillations.
