The receiving end would have the benefits of a transmission link. They would
have the nice pictures and the information. The sponsors of the project
would be able to make their ET movies, sell their ET books, ET toys, ET
hamburgers and ET soda.
The economy at the transmitting side would be more problematic.
- Hey dude! We have this marvelous transmission project. We will transmit a
message into space and we could have a reply within 1000-160000 years or at
least within 4 million years. How many millions do you want to donate?
It is a risk the president on planet Xnorb would rapidly cut the funding to
ASAN's transmission project in an attempt to fulfill his promise to lower
taxes. But the transmitter has to be kept on for several thousand years to
make it possible for a planet with a newly developed radio technology (like
ours) to detect the signal.
The receiving end would probably have to pay for a much larger part of the
link cost then the transmitting side, to make a link possible.
Is it possible at all, to have a transmission project at a cost so low it
can be kept alive for several thousand years? The transmissions has to be
made towards tens of millions of stars where somebody might be listening
thousands of years after the transmissions were made.
Is it possible to still have enuf information contents in the signal to make
it interesting to receive?
