Mister Rogers' Neighborhood Dark Matter Machine (Part 1).mp4



According to supersymmetry, WIMPs act as their own antimatter
particles. When two WIMPs interact, they annihilate each other and
release a flurry of secondary particles as well as gamma rays. Using
GLAST, scientists hope to find these high-energy signatures of dark
matter in our galaxy. If they succeed, this discovery will help solve
one of astronomy's grandest mysteries.

as neutralinos (which are often called WIMPs) annihilate each other,
creating a cascade of particles and radiation that includes medium-
energy gamma rays. If neutralinos exist, the LAT might see the gamma
rays associated with their demise. Credit
