{{main|Timeline of cosmological epochs}}
{{duplication|date=September 2020}}<!--what is the point of keeping two timelines with exactly the same scope, one "graphical" and the other in html table format?-->
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]].
