Big Bang Theory Timeline

Since the big bang 13 7 billion years ago the universe has passed through many different phases or epochs.

Big bang theory timeline.

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. The discovery of quasars supported the big bang theory and went against the steady state theory. In this theory the big bang is just the latest big bang in an endless stream of big bangs in the continual expansion collapse and renewed expansion of space and time. Timeline of the big bang theory.

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. 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. 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.
