This is a timeline that attempts to show the best scientific estimates of the age of past events and predictions of the approximate timing of hypothetical future events with cosmological significance. Some locally significant events of interest to members of Homo sapiens are also included. See estimates of the date of Creation for alternative views based on religious tradition. (Note: in this context, billion means 1,000,000,000).
