Q. What is the basic idea of the cosmological principle?
The cosmological principle allows the universe to change, or evolve, throughout time. An extension of the cosmological principle called the perfect cosmological principle says that the universe also does not change with time; there is no evolution.
Q. Who came up with the cosmological principle?
Cosmological principle, a term coined by the English mathematician and astrophysicist Edward A. Milne to describe the assumption that at any instant in time the universe is, in the large, homogeneous and isotropic.
Q. What is an isotropic universe?
An isotropic cosmology is one in which there are no "special" directions: at a given instant in time, the universe appears the same in every direction (again, on sufficiently large spatial scales). Together, they form the Cosmological principle.
Q. What is isotropic in physics?
In the study of mechanical properties of materials, "isotropic" means having identical values of a property in all directions. This definition is also used in geology and mineralogy.
