Extraterrestrial Communication

1974 - "Arecibo" Message was sent by Professor Drake from the
          newly upgraded Arecibo Radio Telescope in Puerto Rico.

1977 - The Wow Signal Signal was recieved and noted by, Jerry Ehman.

SETI@home uses Internet-connected computers in a massive parallel processing effort
to sift through the massive amounts of data collected by SETI. Users participate
by running a free program that runs constantly or as a screen saver, and downloads
and analyzes radio telescope data, and sends back results.

The Drake Equation, developed by Frank Drake, in 1961, is a way to estimate
how many intelligent, communicating civilizations there are in our galaxy.

N = N* fp ne fl fi fc fL

N* = The number of Stars in the Milky Way Galaxy
fp = The fraction of stars that have planets around them.
ne = The number of planets per a star, capable of sustaining life.
fl = The fraction of those planets where life evolves
fi = The fraction of those planets where intelligent life evolves.
fc = The fraction of those planets that will communicate
fL = the fraction of those planets lives, that the communicating civilization(s) live.

The Fermi Paradox - "Where are they?"
if one plugs in reasonable estimates for the Drake equation,
up to the lifespan of the civilizations. Given the time thats passed
Fermi proposed 3 possibilities:

1) Such civilizations have Long lifespans and are already here.
2) Such civilizations have Long lifespans and have no interest in us.
3) Such civilizations have short life spans, before they self-destruct.
