- Considering how far the energy must travel (recalling that you're energy
- will disperse into a 22,500,000,000,000,000,000,000,000,000,000,000 square
- metre area, the reflectivity of any likely surface, and the fact that it
- must make its way back, what are you suggesting as a transmitter?
-
- IMO, the best solution so far is to simply throw things into space
- with the message written on it in mathematical form. Pretend you're
- communicating with aliens, since that's what 1Byear hence "humans"
- will be. Make the objects self replicating. Throw them in thousands
- of orbits.
-
- Of course, when the Galactic Admin finds out, the Human Race is in for
- one hell of a littering fine. Anything that's going to be around in
- 1 billion years if definately NOT biodegradible!
