Tetryon Particle Research Technology is the study and understanding of Tetryon particles and side effect Tetryon Radiation.

A tetryon is a subatomic particle that can only exist in subspace environments. Tetryon radiation is a bombardment of these particles. Since these particles are a property of subspace, they become highly energetic and unstable when they are extruded into normal space, which can occur by both natural and artificial means. Tetryons have a random momentum, and thus cannot be tracked by sensors.
