I like this site because it lists all major events in order on one page, and all time periods are all linked to more information. If you want to know what happened first, next, or later, and get an in depth accounting of any time period in history (or future possibilities!), this is the place to start.
Starting 15 billion years ago, to where we are today, going towards future possibilities --as many years forward. I read the past, and see the present in the timeline, and poke around in the future --and can only ponder the concepts. ..."This site tells the story of the history of the universe.....a time line of all the main events in the history of the Universe..."
