Unstable particles

Usage examples of hyperons.

The hyperons could combine into stable islands of dense material—Corestuff bergs—which could persist away from the formative densities of the heart of the Star.

Corestuff lends itself to this property, being composed of hyperons, bags of quarks in which are dissolved the orderly nucleons—the protons and neutrons—of the human world.

The core of an exploded giant sun, a mass almost half again Sol's, jammed down by its own gravity till it's that small, that dense, no longer atoms but sheer neutrons, except that at the center the density may go so high that neutrons themselves fuse into something else, hyperons, about which we know little and I lust to know more.
