Cosmology is the study of the origin, evolution, structure, dynamics, and ultimate fate of the universe as well as the natural laws that keep it in order. It also includes the study of the nature of the Universe on its very largest scales.


Cosmic Scale Factor

The Cosmic Microwave Background Radiation (CMBR) or Cosmic Background Radiation (CBR) is the afterglow from the early universe and provides strong evidence for the theory of a hot Big Bang. This article looks at what the CBR is, how it was detected and why it is important for cosmology.
