I am Andy W from Weston-super-Mare in the United Kingdom. I have been a member of SETI for nearly 20 years. I had a 5 year break from the project due to ill health, but have bounced back and am crunching for SETI once again using a 6 core Intel server that is also my weather station server ( http://www.westonweather.co.uk ) and my PLEX media server - so it has a busy life, but SETI is more than welcome to its spare processing power.
Thoughts about SETI and SETI@home
I strongly believe that there must be other life away from Earth. Space is a VERY big place and our planet Earth is only a teeny tiny part of it. To dismiss the possibilities of life elsewhere would be very naive. Humans throughout time have been great explorers, SETI is just taking things one (natural) step further and making it possible for everyone to hold a share in what is the most exciting exploration project mankind has ever undertaken.
I don't think anyone can fully understand what the search for ET can mean for the human race as we have no idea what we are going to find. Maybe ET is far advanced of us? Maybe ET is years behind? Maybe ET is already here or comes here on a regular basis? Whatever we find I hope it is to the better of mankind and the future of the Earth.
I think humans should actively "look" for ET and make it clear to them that we are looking. We should be sending out a beacon (if we don't already?) asking them to make contact and offering our friendship. It may be years before they are able or willing to respond, but if we don't try we are never going to find out.
I run SETI @ Home so I can say that I am doing my "bit" towards the search for other intelligent life. Although the amount of processing power any one individual can donate is small it is far from insignificant. If every PC in the world was put towards this search for only a small amount of time the question over ETs existence would soon be answered. SETI is a fantastic way of harnessing the power available to us and an excellent example of the World Wide Web being put to a good use.
