Scale invariance - Definition and Overview

In physics, scale invariance is the feature of physical objects of laws that do not change if the space is magnified, i.e. the coordinates (or energies) are multiplied by a common factor.

In cosmology, scale invariance is usually used to describe the near-scale-invariant energy spectrum of the cosmic microwave background - a pattern that is well explained by the theory of inflation.
