Last night I came across some research work by Laurence Doyle related to the ‘information theory’ and I was actually impressed (by a SETI scientist for a change). We all are aware about the human efforts to communicate with the so called ‘aliens’. For more than 50 years we have been monitoring the universe chatter which includes the electromagnetic waves to detect or should I say overhear the communication which goes around the universe. Well, the implication of that being the existence of another civilization but let’s not get into the Hollywood stuff.
So, all we humans can hear is static not even some alien gibberish. There could be many reasons for that static. Firstly monitoring a single frequency might the silliest thing to do considering the fact the information is more efficient conveyed through broadband i.e. range of frequencies. And if you are planning to send some information across galaxies and millions of light years definitely you won’t use a single frequency unless, you are as optimist as a human being from planet called ‘earth’.
