What is life? Contemporary theorists agree that it is a) a self-organizing system, which means effects feedback on their causes to produce structure b) this process occurs through a self-referential and other-referential tripartite structure in the cell. For example, all membranes are studded with glycoproteins that respond preferentially to chemicals that are needed to regenerate the endogenous molecules that make up the cell. Thus, the membrane proteins are "other" references, which are metabolically (connected through reactions sequences) tied to the DNA within the nucleus - the "self".

It makes no sense to call DNA the "self'" since it needs the membrane proteins to reconstruct its dynamics. Furthermore, the cell is constantly far from equilibrium, rendering the celebrated idea of DNA "fixity" quixotic, especially since hundreds upon hundreds of "stress tests" conducted on micro and macroscopic organisms have proven beyond all doubt that environmental stress forces an increase in the mutation rates of regulatory genes, and even, in many cases, protein coding genes.

In any case, the above situation describes a Eukaryotic cell, which evolved on Earth around 2 billion years ago. Bacterial life, on the other hand, is close to 4 billion years old, and is organized is differently (less complexly) than the Eukaryote, with no nucleus/cytoplasm distinction, with DNA and proteins floating freely within the bacterial inside, and the bacterial cell thousands of times smaller than the Eukaryotic cell.

It is this difference in complexity between the large Eukaryote and the smaller prokaryote (bacteria), that makes life plausible not just on other planets - but on planets in our solar system, such as Mars, and moons like Titan and Europa. These sorts of living structures would be tiny - but would be comparable to the "extremophiles" that live in deep sea volcanic vents, living off the sulphur ejected from the vents. Such methanogens live in low-oxygen conditions, and may be able to thrive where there is water - such as in mars craters or similar situations on Titan.

Ultimately, life is a "far-from equilibrium" self-contained dynamic that develops a self-reference and other-reference system of 'signs' to maintain its particular activity.

It is microscopic most of the time, but on some planets, the microscopic dynamics come together into slimes, then into more elaborate conglomerates, until a veritable structure is formed (vertebrate) around which subsequent extending and complexifying of energy entrapment can occur.

This thread is a response to the thread on "were the center of the universe". A common, or normal response to reading that would be: "were the center of everything", or, "its just as the bible said". Such "memes", if I may that term, pop into our minds because of the cultural (psychoemotional) heritage we've inherited.

I was thus compelled to remind myself - and others - that we live in a universe where life seems to be a pretty normal process made possible by certain advantageous local conditions. It could be a planet like Mars, or a moon like Titan, or an asteroid with liquid water within its interior around which life can teem; or, it can find expression in a very unusual way as a function of the coming together of conditions that protects the planet in such a way as to permit a 'scaffolding evolution' - and also to 'cull' the Earth at particular times - such as the dinosaur extinction 65 million years ago - so that the mammal - with its myelinated nervous system and unknown potentials for elaboration - could evolve further.

Human life - what we are, is clearly rare. It's about the a) size of our planet, b) the size of the sun, c) the relationship between the Earth to the Sun (distance) d) the influence of the moon on Earth dynamics e) the influence of Jupiter in protecting the Earth from asteroid bombardments.

It's hard to measure something (habitable planets) we don't know the true size of (the universe). Yet, its plausible - that life may be able to proceed in many ways, in many forms, despite the way that affects our self-image as Humans. Yet, one can well wonder with others, whether the types of life produced and the processes life assumes might be very similar. That is, single cellular life will precede multicellular life. The transition may entail some slime mold as the mold has a functional value for each individual, until the individual existence becomes too cumbersome, and the slime mode supports a better existence.

In other words: the universe is logical: it can be understood with reason. To be a Human entails the history of our organism, from the first cells on earth, to slime mold, to eukaryote, to some fish creature, to some amphibian creature, to a reptile, to a reptile-mammal transition creature, to a rat-like creature, to a creature that colonized trees (a lemur like creature) to a primate, to an ape, to a hominid, to a Human being.

This is an arbitrary road, but a road which provided and opened up future possibilities that were, for example, closed off to the crocodilians - which have remained the same for 200 million years. The crocodile has stayed the same, whereas the animalian line that went from reptile to Human has been undergoing remarkable transformation.

One may well wonder: is a Human being something the universe produces? Perhaps, anywhere where the conditions exist? And how much further would such an evolution produce?

No humans capable of passing the radiation belt . Its there for reason. Keeping vires infected sells contained.
edit on 24-2-2017 by Pandaram because: (no reason given)

That is untrue. Even the guy who the belt is named after laughs at people who say that.

Well, with future missions to Jupiter's moons, especially Europa, may tell us that where Earth is located is not so special after all.
Carl Sagan once envisioned, described and had his visions illustrated in his work "The Cosmos" that life can live anywhere, as long as it starts, and is able to adapt to where ever it may grow. He told of giant organisms that were floating around Jupiter itself, later after the publication it was found that life probably would not survive at all within' Jupiter's atmosphere, but that does not mean life can thrive on a much less of a hostile planet, or moon.

Alternatively humans could have been transported by extraterrestrials in the distant past to other habitable planets a la Stargate, Star Trek and Farscape.

Most people barely live on this one.

Which could be debated whether or not we could handle actually going to different ones, or that we're made for it!

Sorry, what was the question?

There is no reason to believe that humans are the end goal of any and every evolutionary path.

That's probably not even true on Earth. In 100 million years, the dominant species on Earth may not be a direct descendant of humans, but descended from some other branch of Earth's tree of life.

I think your confusing imagination with reality.

In reality, what allowed multicellular life was oxygen. Oxygen allowed greater energy, because oxygen is a very large and unstable atom, it is constantly 'accepting' (destabilizing) electrons from others atoms, which allows the construction of chain reactions to occur, which emerge as a function of "inter-linked' molecular systems. One such system central to life on Earth is the citric-acid cycle. The citric acid cycle becomes "regenerated" by the evolution of another chain-reaction which is able to transform oxygen from the environment into usable energy within the cell (electron transfer). All of this has been discovered and described, for instance, by the biophysicist Harold Morowitz in the book "The Origin and Nature of Life on Earth". Nucleic acids (DNA and RNA) and Proteins, in turn, are larger scale (larger molecules) 'constraints' which shape the flow of energy through the system, and so constitute "memorized patterns" of organism-world relations.

Multicellular life seems to need oxygen. What differentiates imagination and fantasy from scientific reality are explanations based in physical reality. Large giant monsters sound nice, but they need planets with atmospheres i.e. with the necessary molecular properties (oxygen) to sustain high-entropy metabolic processes - large animals.

Positing ancient aliens, etc, is merely to engage in infinite regression, where 'aliens' create us, and were forced to as, ad infinitum, "who created the aliens".

I believe our perception of what matter is, isn't anything like we imagined it to be.
And that we Arnt physical at all. But sound.
And with our echoing frequencies we hold matter together. Here on earth. And with all matter in all the universe.
We created ourselves. With thought.
Our thoughts evolve and so do we.
Which is why conscious life evolves but all other matter stays the same...a rock will always be a rock. A sheet of ice will be ice...clouds of gas will be gas....but the trees evolve...animals evolve...humans...evolve. All things with thoughts, have the capacity to WILL a change within their own biological structure. All things need to change in order to adapt to survival. To keep our vessels alive.
So that we may shape a world and gain knowledge in the process.
Then again. None of this could even exist right now, because there is no shred of evidence that can prove reality is even a fabric you can measure. There is no way to justify that our senses are in fact endulging in reality in a way that can prove it is a substance...reality itself could be a program, it could be a thought from one being who is dreaming or in a coma asleep.
Or it very well could be the organic mind of a super computing singularity and each one of us are like cells. Knowledge holders. Power houses. Linked to the same being.
We are born with the spark. And we die with it fleeting.
