| degeneracy |
A state of matter characterized by extreme compactness or density (eg, matter that is a million times or more as dense as water). The pressure of degenerate matter is dominated by quantum mechanical effects and is largely independent of temperature (unlike the pressure of air in a tire, the terrestrial atmosphere, or the gases in normal stars, such as the Sun).
