# What is ISOTROPY OF SPACE?

Isotropy is uniformity in all orientations; it is derived from the Greek isos (ίσος, equal) and tropos (τρόπος, way). ... the most simple instance being free space. Optics Optical isotropy means having the same optical properties in all directions.

Bradley, as early as 1726, made such a measurement of light isotropy when it travels through outer space before it reaches the earth’s atmosphere. Essentially, what Bradley found was that the light traveling from stars travels isotropic to the stars.
