Alien life :Next thinking[ PART:1]

silicon based life

Carbon is a great molecular glue. Simply take carbon and add water , you have just got life. Well, it is not quite that simple , but water and carbon combo has succeeded to win life , at least on planet earth. This combo has successfully spread his root all over on planet Earth . It is worth considering that what may be death to us , may be life for other beings. Many of researcher and biochemists also speculated that there are several combination of molecule and solvents that may cause life forms too much differs from us that we have never thought about it. Currently we are thinking about only our version of “sweet spot”. Our searches for extra-terrestrial life forms is totally focused on planets similar to others. There are many biochemistries which may exist in such extreme conditions , we have never thought about it like on venus , saturn, jupiter and even in neptune and uranus. It is worth considering that who do their lab work , are a simply carbon based human working in planet earth’s atmospheric conditions . Ammonia has almost same properties that of the water on extreme condition .it is also good solvent . May be it’s possible that water is last possibility for capable of having life forms in extreme environmental condition as on planet Earth.
Even counter intuitive element such as arsenic may be capable of supporting life forms under right conditions . Even on earth some marine algae incorporate arsenic into complex organic molecules such as arsenosugars and arsenobetains. Several other small life forms use arsenic to generate energy and fascilate growth. Chlorine and sulfur are also possible elemental replacement for carbon. Sulfur capable of of forming long again molecules like carbon . Some terrestrial bacteria have already been discovered to survive on sulfur rather than oxygen , by reducing sulfur to hydrogen sulfide . Nitrogen and phosphorus could also form biochemically molecules. Phosphorus is similar to carbon in that it form long again on its own,. ..,continue…

    Hi there,
    Can i take a one small picture from your blog?

    Hi, Amazing! Not clear for me, how offen you updating your bruceleeeowe.wordpress.com.

    Carbon + Nitrogen + Oxygen I think can virtually ensure some form of life.

    Carbon + Methane + Sulfur may also work. There is plenty of life on earth that already use this combination in some way.

    Carbon + Ammonia + Methane + Hydrogen may work in gas giants. I.E. Life that exist between layers of gas.

    One important thing to keep in mind is that photosynthesis is only one means of producing energy. On other planets, there may be creatures that feed on purely chemical energy as do organisms that live near geothermal vents on the ocean floor, where no light penetrates.

    The “sweet spot” may be quite wide and varied indeed as life on our own planet shows how well it survives even in inhospitable environments and completely different combinations of elements.

      As you have written the sweet spot for life may be anyehere in universe, I’m completely agree with you
      i have written in next post ,that happens how?

    If we look at the question from the broadest perspective, then we need not (should not) even be confining ourselves to chemistry. If you take the very broadest definition for life – a self-replicating system capable of Darwinian evolution, then the raw ingredients of life are not restricted to a chemical substrate (carbon, silicon, etc) and a solvent (water, ammonia, etc). Instead, all you need is 1. a means of storing and manipulating (and copying) information, and 2. a method of obtaining/generating the energy required for 1.

    So what about nuclear interactions on the surfaces of neutron stars, or convection patterns in the atmospheres of stars and gas giant planets, gravitationally bound clusters of stars or even galaxies? (Time scales would vary widely, of course. For a hypothetical organism where the replication of genetic material depended on the gravitational interactions between stars, the equivalent of a cell division may take several billion years, and we might expect that such lifeforms would not have had the time to appear yet, in a universe only 14 billion years old)

    On the other hand, from a practical point of view, it is difficult to systematically search for something you know absolutely nothing about, and have no a priori method of determining which of your many conjectures is more or less likely than any other. It makes sense that when you first start looking, you look for what you already know.

    Thus, starting with knowledge about life-type A (earth life), it makes sense to first look for life-type B (life that shares properties with earth life), and then, after finding B and comparing its similarities and differences with A, use that knowledge to intelligently plan a search for life-type C, and then D, and so on. We accept the inevitability that while searching for B and C, we are likely to overlook life-type Z, with the understanding we will come back later, armed with more knowledge and understanding, to find Z, because if we try to look for Z at the very start, with only knowledge of A, there is no reasonable way to expect any chance of success, except by luck.

    Which is not to say that when we are focused on searching for B, C and D, we do not keep our minds open and our observations attentive, such that if, by luck, we stumble upon X, Y, or Z, we do not miss the opportunity provided by serendipity.

    • bruceleeeowe says:

      Again I’m agree with your arguments. But what is probability that life on other planet is surely of type B or C[similar to such extent as life on earth]. And it comes as more indigenous for me that life on other planets will be radicaly different not sure to what extent. Or there may be Robert Forward’s Cheela[intelligent species evolved on neutron star based on nuclear reactions rather chemical] like scenario where intelligent aliens are very small compared to human and time dilation also comes as mountainous complexity[since nuclear reactions are millions times faster than chemical thus they grow up and evolve unexpectedly fast] in communication and detecting them. Yet I agree we discover it provided by serendipity other than aliens itself contact us.

  5. I am the sort of guy who loves to taste different stuff. Right now I am building my own solar panels. I’m doing it all by myself without the help of my men. I am utilizing the internet as the only path to acheive this. I ran across a really awesome website which explains how to make photovoltaic panels and so on. The site explains all the steps needed for solar panel construction.

    I’m not sure about how accurate the info given there iz. If some people over here who have experience with these works can have a see and give your feedback in the thread it will be great and I’d highly treasure it, cause I extremely take an interest in [url=http://solar-panel-construction.com]solar panel construction[/url].

    Thanks for reading this. You guys are the best.

The site explains all the steps needed for solar panel construction.

    I’m not really sure bout how accurate the information given there is. If some experts over here who had xp with these works can have a see and give your feedback in the thread it would be grand and I would highly treasure it, cause I really passion solar panel construction.

    Tnx for reading this. You people are great.

    Hey, ok, I get it, I guess – but does this really work?

  8. Self Esteem says:

    Thank you so much, Great information… You keep writing and I’ll keep reading.

  9. Hungover Guy says:

    As much as I can understand right now, I think you’re right!

  10. Field Turf says:

    Great information, Thank you so much… keep up the great work.

  11. cipcipcia says:

    how can I add to bookrmark your blog? would you like to visit mine? regards!

  12. If your theory is right, maybe there’s life in planets like Venus, where we’re used to think life is impossibile!

    By this point of view, more probable in Venus than Mars…

  13. bruceleeeowe says:

    Hi, Dr. Oltrantza
    mars and venus both hold the the same probability for being capable of thriving exotic life forms within their atmosphere. Venus has hot vents,so if life is thriving there,it would be very exotic wherever life forms on mars would be more likely based on carbon based since its terrestrial environment is similar to Earth to some extent. So both hold the key to life,just what we need is widening of mind and searching for life on most vulnerable vents. 😉
