| Thoughts about SETI and SETI@home |
|---|
SETI home is a noble project and most importantly relatively cheap. To search for ET life is our scientific duty. It is great that so many people desire to participate.
We must know, however, that our chances of contact are quite small. Our technology and knowledge is barely enough to make us realize how pitiful our efforts are. Does ET life exist? Possibly YES. Can we contact them? Doubtful. Why? Time is always the problem. Perhaps life can exist somewhere near us, but the universe is "old". Billions of years old. Our civilization emerged in just the recent few thousand years. The time shift between 2 civilizations willing to contact each other cannot be greater than that. 1 billion/1 thousand=1 million. 1/1.000.000 is the chance of this actualization. But let us say that it does in fact happen, and we receive a signal. The Doppler effect tells us that the signal was sent about 250.000 years ago. Shall we return a message and wait an additional 500.000 years for a reply? Do they still exist? And do we even care about who receives their reply? Will there be anyone to receive the message here on Earth in 500.000 years? I doubt it.
Therefore light speed is not enough. That is the best we know so far. However, I am very optimistic about other ways of communication. The most complicated structure in the universe lies in our heads and this will lead our technology beyond what we can even imagine.
On the other hand, I am not sure if we want to have any contact beside radio, with an intelligent alien life. Theory of evolution says that the collision of 2 isolated, independently evolving environments leads to serious complications- including the total annihilation of one of them. We know examples of this.
While allowing our computers to work on SETI units we should concentrate more on our own planet. Although I believe in ET life, I do not believe that there is any planet in the universe that is as rich in incredibly diverse life forms as the Earth. Our planet is the perfect one. We shall appreciate it some day. |
