Beyond 10,000 AD

Long Now encourages a 10,000 year perspective, but if that just isn't enough zeroes for you, check out FutureTimeline.net, a site that literally goes Beyond 10,000:

Welcome to the future! Here you will find a speculative timeline of future history. Part fact and part fiction, the timeline is based on detailed research that includes analysis of current trends, projected long-term environmental changes, advances in technology such as Moore's Law, future medical breakthroughs, and the evolving geopolitical landscape. Where possible, references have been provided to support the predictions. FutureTimeline.net is intended to be an ongoing, collaborative project that is open for discussion – we welcome ideas from scientists, futurists, inventors, writers and anyone else interested in the future of our world.

As a resource for science, technology and futures thinking, the site is chockfull of links and ideas. Just as an example, did you know that in about 3,000,000,000 AD, our own Milky Way may begin to merge with Andromeda?
