Having watched the movie contact was, kind of enlightening. Not that the facts handled in the movie was unknown, but the way it was told makes it more realistic.
Apart from the political drama, it was very well done.
Now for some of the facts that I have gathered:
SETI (Search for ExtraTerrestrial Intelligence), was a program originally launched by the United States government. The U.S contributed to earlier SETI projects, but recent work has been primarily funded by private sources.
In 1960, Cornell University astronomer Frank Drake performed the first modern SETI experiment. Since then only once a possible non-terrestrial radio signal was found. It was named the WOW signal. After that SETI project has never aroused much interest. Perhaps, due to the fact, that the space is too big for the humans.
Although, this part of science doesn’t get much respect in the field of astronomy, postulating regular communication in several star systems makes a successful SETI effort more defensible.
In other words it is highly unlikely that we are going to make contact with a Extraterrestrial civilization with just SETI. We need intergalactic travel systems for that. Which is extremely expensive, so much expensive that the entire human society funding for a intergalactic travel will not be enough.
Despite all these facts, I believe there is definitely some one out there. As it was told in the movie
“if it is just us... seems like an awful waste of space”.
