Negative Physics

A conceptual framework for describing physical quantities that can take on negative values in meaningful ways, beyond just mathematical convenience. Negative energy densities (predicted by quantum field theory), negative temperatures (achieved in laser systems), negative pressure (driving cosmic inflation), and negative mass (hypothetical) all fall under negative physics. It's the study of the physical regimes where our intuitive sense that "more" means "bigger positive number" breaks down, and the universe reveals stranger possibilities.
Example: "The Casimir effect proves negative energy densities are real—a genuine phenomenon of negative physics where empty space has less than zero energy between two plates."

Negaverse

Word sometimes used in fanfiction writing to reference a hypothetical version of the real world where the events portrayed in said fanfic are canon, usually (though not necessarily) replacing the original piece of media being written about.
Fanfic Beta Reader: "I didn't quite understand your last chapter. Is the plot some kind of reality show or something?".

Fanfic Writer: "No, no, it's just comments from negaverse. I thought it would be a fun interlude between arcs".

Negative concord

A textbook term that explains informal, illogical uses of double negatives when the intention is to convey a single negative in a sentence. This phenomenon goes against traditional English rules and effectively contributes towards the downfall of societal intelligence.
Person 1: "I didn't do nothing".

Person 2: "Did you just say a negative concord"?
Person 1: "What's that"?
Person 2: "It's when you say a double negative when you don't intend to. You don't sound smart when you speak like that".
