Does Alien life Exist ? – Sorry, it doesn’t !

I read a really amazing book recently called The Eerie Silence – Are We Alone in the Universe.

If you are interested in the search for extra terrestrial life then this book draws some very interesting conclusions and is well worth reading. The book starts off by looking at our own world to see if we can draw any evidence about whether the human race might be a one-off  species or whether we might be just one of millions of life forms that throng the universe.

The conclusions of the book are a little depressing because of the authors opinions about whether there might be life on other planets. He also gives a fascinating insight into the future of the human race.

I say depressing because the author is the head of SETI, which stands for “search for extra terrestrial intelligence” so this guy should know a thing or two about the chances of finding  alien life. His conclusion is that he thinks the human race could be alone in the universe. After reading his book he certainly offers compelling evidence that we might well be alone.

Firstly, we have been looking for evidence of alien life for about 50 years. Our technology over the last 10 years has improved greatly to the extent that we can see much further into space that we have even been able to see. So far, all this searching has found not one once piece of evidence that there may be life elesewhere.

Secondly, if you look back at the history of the human race it is a series of accidents that quite possibly could never happen again. The author of the book describes the chances of life emerging as being like a “whirlwind going through a scrap yard and putting together the best aeroplane that ever existed”. I think that is a very good analygy.

If we were to discover radio signals coming from another planet the distances involved are likely to be so great that it would take hundreds of light years to them to reach us and for us to reach them. As we can’t travel at the speed of light yet and probably never will be able to this means it would take thousands of years to travel the distances involved. This poses several problems, of course. By the time we have travelled the distance the life we are trying to reach may well have died but more importantly, we can’t live for that long either !

This is where things start to get interesting because in our quest to seek out new life forms us humans will have to change and this also ties in with the way us humans are evolving. I think that it is clear that humans will evolve artificially. What I mean is that medical science will prolong our lives by genetic engineering and by giving us man made bits of body that don’t wear out. Effectively, this means we will eventually change into machines !

Scientists think that they will be able to download the contents of a human brain onto a computer by about 2030. Already, we have man made limbs. All the body does is do what the brain wants so if you can have a computer as a brain and a man made body then you have a robot. This will lead to humans living longer and more importantly, it will mean that we can travel longer distances in space. This will happen because it is the only way that we will be able to travel the incredible distances involved in deep space travel.

By the year 2100 us humans will be completly different !

Buy the book. It’s excellent !

  1. I disagree, I think its very likely to exist.
    in our own solar system, the recent missions to Mars have uncovered evidence of water erosion on the surface, the possibility of water ice below the surface, and the presence of methane in the thin atmosphere. Methane is produced either by volcanism, or life, and exists for a short time before it breaks down. There is no sign of current volcano activity, so there is a possibility of microbial life, below the surface, in water ice. Future missions by NASA, ESA, and other agencies will be investigating further.
    Further out, numerous exo-planets (planets orbiting stars other than the sun)are being discovered by various forms of telescope. The technology is nearing the point of being able to detect earth sized exo-planets, and a number of rocky planets (larger than earth) have been detected, and appear to be commonplace. It seems only a matter of time before an earth sized planet, in an earth type orbit, around a sun like star, is discovered.
    I feel more optimistic than your book author appears to be, I doubt if we will have the technology to detect life outside the solar system for at least a few generations, but we might just get to find microbial life on mars or elsewhere in our own solar system, during my lifetime.
    I dont think Ill get “The Eerie Silence”, but I will keep a casual eye on the updates from the current Mars missions.

    1. Paul. Thanks for your comments. It is certainly a topic that has always prompted interesting debate. I suppose that there is a difference between finding intelligent life and micro organisms and it is more likely that we will find some form of life somewhere on another planet. We should, of course, all keep an open mind about these questions. Maybe as I get older I am looking for an answer that I will probably never find out !

      I think what is clear though is that should be find evidence of intelligent life it will pose an interesting question as to how we will travel the enormous distances involved and whether we should ever attempt to do so !

  2. I DISSAGREE I THINK THAT WE CAN NOT BE THE ONLY BEINGS IN THE ENTIRE UNIVERSE. WE DONT EVEN KNOW HOW BIG THE UNIVERSE IS BUT WE DO KNOW THAT THERE IS MORE TO IT THAT MEETS THE EYE. MAYBE WE ARE THE ONLY LIFE IN OUR SOLAR SYSTEM OR GALAXY BUT FROM MY POINT OF VIEW WE CAN NOT BE ALONE IN THIS UNIVERSE.
    THERE MAY NOT BE LITTLE GREEN MEN WALKING AROUND(IM NOT SAYING THAT THERE IS DEFENETLY NOT) BUT THERE MIGHT BE LITLE GREEN BUGS ROMING ONE OF THE PLANETS IN ONE OF THE SOLAR SYSTEMS IN ONE OF THOSE GALAXYS AMONGST MANY IN THE COSMOS.
    WE MIGHT NEVER FIND ANY LIFE BUT THERE IS EVIDENCE ALL AROUND US LIKE FOR INSTANCE UFO SIGHTINGS, WATER EROSION ON MARS, ASTROID FOSILS AND MANY MANY MORE. BUT I DOUGHT THAT ALIENS IN AN OTHER GALAXY COULD TRAVEL THE FAST DISTANCES WITHOUT A WARP OR SOME KIND OF WORM HOLE MASHINE, EVEN AT THE SPEED OF LIGHT IT WOULD TAKE HUNDREDS OF THOUSANDS OF YEARS TO TRAVEL FROM THE NEAREST GALAXY IN OUR CLUSTER, ANDROMEDA. IT MAY BE POSIBLE THAT LIFE COULD TRAVEL WITHIN OUR GALAXY AT THE SPEED OF LIGHT(AFTER ALL TIME SLOWES DOWN AT THE SPEED OF LIGHT BUT IM NOT GOING TO GO IN TO THAT NOW).
