Big Bang Theory Timeline

According to the steady state theory these quasars should be found all throughout the galaxy but they are only found on the outskirts which supports the big bang theory in which the universe is constantly expanding.

Big bang theory timeline.

Since the big bang 13 7 billion years ago the universe has passed through many different phases or epochs. The model describes how the universe expanded from an initial state of extremely high density and high temperature and offers a comprehensive explanation for a broad range of observed phenomena including the abundance of light elements the. In inflationary models of cosmology times before the end of inflation roughly 10 32 seconds after the big bang do not follow the same timeline as in traditional big bang cosmology. Timeline of the big bang theory.

Working backwards from the current state of the universe scientists have theorized that it must have originated at a single point of infinite density and finite. Due to the extreme conditions and the violence of its very early stages it arguably saw more activity and change during the first second than in all the billions of years since. Models that aim to describe the universe and physics during the planck epoch are generally speculative and fall under the umbrella of new physics.
