steady state theory

n.
The theory describing a steady state universe. Also called continuous creation theory.

stead′y state′ the`ory


n.
a theory that maintains that the average temperature and density of the universe are held constant through the creation of new matter and energy as the universe expands. Compare big bang theory.
[1950–55]

steady state theory

The theory that the universe has always existed and been expanding. This theory, which was formulated in 1954, has been largely rejected in favor of the big bang theory.
