Gamma Ray

Gamma Rays-- scientifically known as P-brane Gamma-class Particles-- is an energetic particle that was discovered in the 1900s by French chemist Paul Villard. In nature PGP emissions are almost universally encountered with the gamma photons associated with the decay of an atomic nucleus. Villard believed that the PGP particles were a component of the gamma photons his experiment was producing. "Gamma waves" entered the public nomenclature during the Atomic Era and became a catch-all for any high-energy fields or emissions.

The work of astrophysicist Erik Selvig identified PBGP particles as distinct from gamma photons. This discovery provoked a flurry of new research and the nickname for the find: "Pretty Good Particles". PGP emissions have been seen to spike noticeably during highly energetic events such as ships entering or leaving Hyperspace, or in the wake of significant reordering of otherwise stable matter.

Bruce Banner attempted to use PBGP particles to stimulate human development and growth.

The tellurium matrices in Kryptonite can store and emit significant amounts of PGP, which is extremely lethal to Kryptonians and Kherans.
