Detecting life in outer space - NOT amateur radio

As far as I know SETI, the search for intelligent life in outer space, has been going for about 60 years without success. 

According to a link in Amateur Radio Weekly there may be another technique. If we find intelligent life "out there" it could/should have a profound effect on life on Earth. 

Excuse the journalism in the link!

SETI (the search for intelligent live in the universe) - NOT amateur radio

To the best of my knowledge this has been going on since the mid 1960s at least, without success. 

Now AI has been brought in to help data processing. According to the BBC there are potentially 10-50 billion places where intelligent life could exist just in this galaxy alone. 

There are so many variables like where do you look in the electromagnetic spectrum. Indeed, is this the best place to look? 

If we found signs of intelligent life, it could have profound effects on this small blue dot.

Staggering numbers - NOT amateur radio

Continuously, I get amazed by the number of planets in the universe. One estimate puts the number of planets as 10,000,000,000,000,000,000,000,000, which is totally mind blowing. 

At the same time SETI has been searching the universe since the 1960s and have found not a single sign of intelligent life. To me, I find this odd. In the early days, equipment was not as sophisticated as today. However, by now, I would have expected to find something.

My only conclusion is that our view of the universe must be flawed or that we are somehow missing something important.  

To me, all our religious beliefs are too "Earth centred".

I look at the heavens and feel awe.

Intelligent life "out there" - NOT amateur radio

As far as I am aware the SETI project has been looking for intelligent life in the universe for almost 60 years. As far as I know, nothing has been detected. Maybe our methods are flawed?

What seems probable, but not certain, is that "out there" somewhere intelligent life does exist. Even with pessimistic estimates there are 10s of intelligent civilisations in our galaxy. There are trillions of galaxies in the observable universe, so the probability of intelligent life existing somewhere goes up. They may be so far away that we cannot interact with them, but with time we may detect some of them.

All this makes me puzzled. All religions seem too small and too human-centric.  Life is a total mystery.

Intelligent life in the universe - NOT amateur radio

This is a subject I have discussed before. Some estimates put the number of planets in the visible universe as capable of having intelligent life as as high as 1400000000000000. Others say intelligent life is incredibly rare.

As far as I know, we have been looking with SETI since the mid 1960s and have, so far, found zero evidence.  Maybe we are looking in the wrong way? As time goes by, we have more sophisticated ways of looking with ever greater sensitivity. Mind you we only discovered electro-magnetic radiation a few hundred years ago. Maybe many societies have discovered something better?

One thing is certain: should we find any signs of intelligent life "out there", it could have profound effects on human life.

SETI - NOT amateur radio

As far as I know, we have been searching the universe for almost 50 years via SETI (search for intelligent life) without success. Much of the decoding is done by volunteers using spare processing power on their PCs.

Based on the estimates of planets, I find this odd. As time goes by the means of looking have improved. By now, I would have expected to get some indications.

Maybe, we are looking in the wrong way? Maybe intelligent life self destructs? Maybe we really are alone? Maybe our whole understanding of the universe is wrong?

If ever we did find intelligent life elsewhere, it could have profound implications for humans.

Astronomical Numbers - NOT amateur radio

According to Google there are 10,000,000,000,000,000,000,000,000 planets in the visible universe. This is a huge huge number.  

Only some of these planets may have intelligent life, but even if this is just a tiny fraction of the number of planets, this is still a huge number.   

I find it mind blowing that I am here at all. One of the greatest puzzles is human consciousness.  On Earth we have about 8000,000,000 people. In such a vast universe, you would think kindness and love would have no meaning, yet nearly every human knows this is not the case.

Although we have being trying for about 50 years via project SETI, we have still not found any signs of interstellar intelligent life as far as I am aware.

SETI - NOT amateur radio

As far as I know, the SETI program ( the search for extra-terrestrial intelligent life) has been going since the 1960s. To this date, I am not aware of any success. I suppose it is just possible that certain governments have kept results secret, but I think this is highly unlikely.

The widely quoted Drake equation predicted we would find many such civilisations "out there".  Oddly, not one has been found!  Something must be wrong with how we are searching. After all this time, surely we would have spotted some evidence?

The evidence for planets around distant stars is growing daily, yet still the hunt goes on. I wonder what the issue is?

As far as I know, we have still to get any evidence of life on other planets at all, whether intelligent or not!

I am not saying stop looking, but I am puzzled.

SETI - NOT amateur radio

In the visible universe there estimated to be 1 billion trillion stars. And that is just the ones we can see!! If you say 1% of these have planets this is still a huge number. Of these, you would have thought some would have life and some of these intelligent life.

To my knowledge, we have been looking for over 50 years yet found nothing via the SETI (search for extra terrestrial intelligence). Either intelligent life is very rare indeed, or we are looking the wrong way, it is too weak to detect, or it is not there.

Should we ever find out that we are not alone, it should have a profound impact on life on Earth.

SETI = Search for Extra Terrestrial Intelligence

We have probably been searching of extra-terrestrial life now for about 50 years. Years ago, the famous Drake equation predicted the chances of finding intelligent life as quite high. All these years later we have still not found any signs! No sign of any extra-terrestrial life, let alone intelligent life.

Perhaps we are truly alone in the universe? Perhaps we are looking in the wrong way?

Should we succeed, it could be transformative. However, I am beginning to have my doubts.

Years ago I recall reading "We are not alone" by Carl Sagan. Perhaps we are alone?

Personally, I think we should keep looking, but I am quite surprised that we have found nothing at all.
