I stumbled across this article by Amara D. Angelica about the Internet and what it will be like in a million years from now. He talks about how the Earth has already input information into the universe through microwave towers and soon NASA will use the information in the Universe to locate asteroids and other matter floating around there. Angelica talks about communicating with civilizations on other planets and galaxies the next million years. It is really interesting to think that communication with other planets would be possible in some million years from now with technology that began less than 100 years ago.
