This became the notion that the universe is the same everywhere and has no center, known as the cosmological principle.

These two assumptions together are known as the Cosmological Principle.

Given the cosmological principle, Hubble's law suggested that the universe was expanding.

This supports the cosmological principle that at its largest scale the universe is homogeneous.

These two conditions make up the cosmological principle.

This "perfect cosmological principle" as it would come to be called predicted a universe that expanded but did not change its density.

Lemaître had already shown that this was expected, given the Cosmological Principle.

The cosmological principle implies that at a sufficiently large scale, the universe is homogeneous; different places will appear similar to one another.

The cosmological principle contains three implicit qualifications and two testable consequences.

On top of that, the universe appears to be isotropic and homogeneous in accordance with the cosmological principle.
