“I have realized that the past and future are real illusions, that they exist in the present, which is what there is and all there is.” – Alan Watts

KEO is a space time capsule which will be launched in 2010 or 2011[1] carrying messages from the citizens of present Earth to humanity 50,000 years from now, when it will reenter Earth's atmosphere. [...]
Every person is invited to write a message addressed to the future inhabitants—the deadline is December 31, 2009. Messages can be posted via the project's website, or sent by postal mail. The organizers encourage everybody to gather messages from children, senior citizens and the illiterate so that every culture and demographic on Earth is represented. The satellite has enough capacity to carry a four-page message from each of the more than six billion inhabitants on the planet. Once the satellite is launched, the messages (with personal names removed) will be made freely available on the web.
