### isotropy

**(statistical isotropy)**
(uniformity in all directions)

**Isotropy** means uniformity in all directions.
This is an assumption made about space, i.e., the
universe which is one of the assumptions of the
cosmological principle, in turn an assumption of the
Big Bang theory.

The opposite of isotropy is anisotropy.
