The Madame Psychosis show (p. 185)
The engineer's graduate research specialty is the carbonated translithium particles created and destroyed billions of times a second in the core of a cold-fusion ring. Most of the lithioids can't be smashed or studied and exist mostly to explain gaps and incongruities in annulation equations.
Context
The student engineer's day job, dropped in mid-broadcast: inside the cold-fusion ring, particles are created and destroyed billions of times a second — and some exist only to make the annulation math close. Even the physics needs phantom entities to keep its circle consistent.
