Graphical timeline of the universe
(Redirected from Graphical timeline of our universe)
It has been suggested that this article be merged into Graphical timeline from Big Bang to Heat Death. (Discuss) Proposed since February 2024. |
This more-than-20-billion-year timeline of our universe shows the best estimates of major events from the universe's beginning to anticipated future events. Zero on the scale is the present day. A large step on the scale is one billion years; a small step, one hundred million years. The past is denoted by a minus sign: e.g., the oldest rock on Earth was formed about four billion years ago and this is marked at -4e+09 years, where 4e+09 represents 4 times 10 to the power of 9. The "Big Bang" event most likely happened 13.8 billion years ago; see age of the universe.
