The agreement of independent measurements of this age supports the ΛCDM model that describes in detail the characteristics of the universe.

American astronomer Edwin Hubble observed that the distances to faraway galaxies were strongly correlated with their redshifts.

This was interpreted to mean that all distant galaxies and clusters are receding away from our vantage point with an apparent velocity proportional to their distance: that is, the farther they are, the faster they move away from us, regardless of direction.

The Big Bang theory offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the CMB, large scale structure, and Hubble's Law.

The framework for the Big Bang model relies on Albert Einstein's theory of general relativity and on simplifying assumptions such as homogeneity and isotropy of space.

Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.

After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms.

In the most common models the universe was filled homogeneously and isotropically with a very high energy density and huge temperatures and pressures and was very rapidly expanding and cooling.
