Scroll through this ingenious interactive timeline to see events that have happened since the Big Bang. The timeline uses historical events gleaned from Wikipedia. Click on an event to see information and related events, and for some, a video. A changing list of categories of events, e.g., a war or a theme, also appears in a column on the left. The site self-updates as new events are added to Wikipedia. May not support the Firefox browser, but works in Chrome and Safari.
