Aliens, Are we alone in this Universe? Options

[vivekpm]

Aliens!!! This is the topic which intrigues me everytime I ponder upon it...

I used to run SETI sometime back hoping that I would some day help in making contacts with extra-terrestial creatures .

Would like to invite talks on this topic. One thing that I have always wondered is why have most, if not all, research on aliens concentrated in finding possible places in universe which can support life, that is, which has water in some form, sustainable temperatures etc...? Is it not possible that the definition of life can be different for aliens? I mean they may not require water at all. They may sustain only at 1000+ temperatures or at sub-zero temperatures. Why is this not possible? After all, the notion that to sustain life we need favourable conditions like presence of water etc., is concieved by us. For aliens, "favourable conditions" may be different.

Would request anyone who has done some reading on this to please throw more lights and possibly supply pointers to good research material...

Cheers,
Vivek...

PS: Thanks NimmiJi for this new forum...

Yes you are right vivek

another interesting part of SETI is that one group is interested in exploring intelligent life other than our earth ...knowing about their living circumstances..ofc the benchmarks are set according to our earthly environment e.g. water , air etc.
while another SETI researchers claim that these kind of benchmarks are of little use as scientists have found form of lifes on earth where LIVING is next to impossible for species like MAMALS , BIRDS ,etc.. e.g. Bacterias,micro organisams are found near natural hot water ponds having water temperature more tahn 60-70 degrees .
Just few days back marine scientists have tried entering robots in to sea deeper than ever ...can't recollect the depth but ...depth was around 6000-8000 feet (meters ?!) ...and they said that was total REAL ALIEN world for us .
If some day we find alien signal or another way of communication than problem arises of LANGUAGE !!!!! .... Scientists have found DOLPHINS , WHALES have their some sort of language which we knows as ULTRA SONIC sound waves....

will continue...sorry basss hai
