The World as Mystery: Life, Here and There

There is an idea I’ve held in my head a long time, from the time when I was a child. It is that the universe is a very large place, holding an impossible number of stars with an uncountable number of orbiting planets, and that therefore there must be other sentient life in the universe. In fact, there likely is quite a lot of other sentient life in the universe—an unimaginably diverse mixture of creatures evolved out of their own unique planetary contexts that, in all likelihood, would often come across so alien to us that at times we would not even recognize them as sentient beings if they were staring us in the face.

Of course, I have no proof of this, no true certainty. But I do have what I consider very good odds, based on the limited knowledge we have of the universe and its immensity. Given even that little bit we know, how could the above paragraph not be true?

It’s fun to think about what those other creatures may look like or be like, how they may live, how they may think and interact with the world around them. It’s also very hard to think about that, because it’s very hard to imagine something truly alien, without touchstone to all the basic elements of life we take as granted and necessary. What would it even mean for lifeforms to evolve over billions of years on a different planet? In what ways would a different planet fashion a different biology? Would all the biological necessities that we attribute to the evolution of life hold true across different planets? Or would different environments create different necessities?

The frank reality is that our definitions of life are based on rules designed around our observations of life on this planet. Which means our definitions are not hard and fast rules; they are not laws; supposed biological necessities are nothing of the sort; they are simply assumptions based on a series of observations necessarily confined to Earth. It is entirely plausible that the rules built around our observations of life on this planet are not applicable to all other planets. They may be applicable with some variation to some planets, mind you, but the notion that the rules of life on this planet are the rules of life everywhere strikes me as a dangerous assumption given the universe’s scale. It strikes me as even more dangerous given that those rules have been hard to define even here, on this planet, and they have had to be expanded due to ongoing observation. In other words, we don’t have a clear sense yet of how to define life on this planet; what are the odds we know how to recognize it everywhere else?

What that opens up to my mind is a fascination that is two fold. The first is the question of what might life look like—and how might it live and behave—on other planets. The second is, are we sure we’re aware of all the life here on our own planet?

In some ways, we know we aren’t aware of all the life here on our own planet, if only because it is so hard to define what constitutes life. As this article notes, the question of whether a virus is alive is an open debate. Viruses demonstrate five key indications of being alive, but some biologists don’t consider them alive because their survival is dependent on other living cells. Why this would suggest they are not alive is a strange concept, to my mind, and may be a good demonstration of the way in which we take for granted the intricacy of the ecosystems that support us. After all, it is hardly a stretch to note that the earth itself is akin to a living cell, and that our own survival is utterly dependent upon our residence within it.

But that aside, the takeaway here is that the definition of life even on this planet remains one of debate. In addition to that debate, the scientific community has found new forms of life originally unknown. The 1977 discovery of deep sea hydrothermal vents changed the views of life on Earth. And within the last few years, further examination of microscopic organisms called hemimastigotes suggested that they might constitute an entirely new kingdom of life. No doubt in future years there will be new discoveries and new controversies as to what exactly constitutes “life” on this mysterious planet we call home.

To my mind, though, this raises a broader question about our limited definitions of life. It’s not just that we may find new forms of life that otherwise are familiar; or that we may realize that organisms we were already aware of are stranger than we thought; but that perhaps there are kinds of life even here on Earth that are utterly alien to what we imagine life to be, or that do not behave according to the rules we have set down. It may not only be on other planets where life takes on bizarre alien forms; what if such life exists right here on our own planet but because it doesn’t conform to our expectations, we don’t notice it?

After all, we think we have some grasp on the boundaries of the material world, but we don’t really. We know how gravity works and can define its impacts through mathematical equations, but we don’t actually know what physically creates gravity’s effects. Similarly, physicists postulate that the vast majority of the universe is made up of dark matter, but it has never been observed and it is unknown if it actually exists; or if it does, what it actually is. It is something that we have evidence of existing, but that we cannot actually observe or confirm exists.

What’s interesting about that to me is how close that sounds to the gods. Human religion and mythology has postulated the existence of a god or gods throughout our known history, attributing observed and experienced phenomena to those beings, but we have not through standard scientific process been able to confirm their existence. (One might argue confirmation through other means, but we will set that aside for the moment.) However, there is evidence that can be explained by their existence, no matter how strenuously your average materialist may object to such a proclamation.

Well, what if the gods—or what we take as the gods, as well as a host of other religious beings—are simply another life form found here on earth, but arranged under a set of rules that diverge from what we normally think of as life? What if they are perfectly real but not made out of matter as we understand and recognize it? Corey Powell, for instance, in an article in Discover Magazine, questions whether there may be dark life, made out of dark matter. If there is, it could function as a shadow universe overlaying our own light matter universe—what we tend to think of as the whole of existence but that physicists believe is not. Could gods be made of dark matter? Why not?

I don’t know that I actually think the gods, should they exist, are made out of dark matter. But there’s no particular reason that it could not be the case—or that, more likely, the world features other strange realities that we are too often incapable or unwilling to see. We cannot comprehend what we haven’t seen or experienced, because our understanding of the world is rooted in our individual and collective experiences. Humans, at the end of the day, are not gods; we are extremely limited in our view of the universe, both physically and mentally. This is a far more complex place than we can comprehend.

And yet we do have individual and collective experiences of disembodied and non-human beings. Not all of us do, but most humans throughout history have. From a modern, scientific materialist standpoint, those are often dismissed as superstition or misunderstood phenomena. Yet the world is a mysterious place, and we are limited in our understanding of it. Are we sure that an unknown world doesn’t exist around us, peeking through in mystic experiences and unknown phenomena? I’m not so sure we should dismiss the possibilities of mystery. In fact, I think we should embrace them. And as this series of blog posts continues, I’ll be doing just that.

  1. Wadja mean alien life? We don’t even understand OUR life! The process called digestion is not understood. We know a whole lot of human tissue is devoted to the task: starting with nose, teeth and tongue in the penthouse right down to the bins in the sub-basement. But we do not know exactly what is going on in several floors of the middle and lower middle sector. The small intestine is the dark continent of the 21st century – one of them, anyway. Sci-fi writers have long speculated about silicon-based life instead of carbon-based, and Gas Beings who breathe methane (either in or out). But, how can we possibly be sure that what we call basic laws of molecular-atomic structure hold true, * universally * ? Well, we cannot, of course. If, as Kant says, Time and Space are merely the shopping bags we carry around in our heads to hold sensory impressions in and the brain is the cupboard where we store the goodies (he didn’t put it quite like that), then perhaps matter doesn’t matter to other kinds of entities. We can, in our dimension, think of matter as frozen light, but what about beings who live in a less ‘Arctic’ environment – a ‘tropical climate’ where no frozen ‘snow’ ever naturally occurs? Sounds sorta heavenly don’t it? Maybe in those dimensions (if and wherever they may be) laws of movement are different. Instead of every action having an equal and opposite reaction, maybe the Law there is ‘Every action has a fivefold kickback’. Or a fractional reactional transactional. Only one-fourth of the effort you make comes back to wallop you upside the head. Provided you have a head and are not an amorphous gas cloud or a Frisbee-shaped bit of plasma.


  2. Quantam Physics in Pine-woods

    Chieftain physican of quantam in the can
    of modles’ moodles in the hand, hup!

    Demned universal constants, as if the sun
    were cockamamie cook to hot your primal soup

    Fact! Fact! Fact! Fact! I am the Observer.
    Your world is blue. I am my world.

    You nine-foot polar magnet among muons, move on!
    Began! Conscious matter rustles in these pines.

    Rustles and points their Appalachian dangnabbits
    and fears not importalled physican nor his whose.

  3. Hi G. Kay,

    Exactly! We hardly know a damn thing when it comes right down to it. And honestly, we’re quitelimited in what we can know because we’re still, at the end of the day, pretty limited as a species.

    Most of these questions are above our pay grade. We’re hardly the people to ask what qualifies as life. We don’t even know what qualifies as our own bodies! Are our own personal microbiomes part of our body? Are they a part of what we think of as “me,” a part of our own individuality? Or are they just along for the ride? Given the interdependency, the latter seems like a pretty shallow understanding.

    The old solar system of classic science fiction presupposed habitable planets in our solar system, often teeming with life. Now we know that’s not true. Or is it? Maybe we just can’t see the life. Maybe we can’t recognize it. Or maybe it’s right in front of our face and we just see it wrong. What about the sand, the rocks? Are they alive? Of course, maybe the planet is full of beings that are more akin to what we think of when we say “beings,” but they exist on a different plane we aren’t privy to. We can’t even see all the spectra of light! Who says we have any idea of all the spectra of matter? Or who says there aren’t beings made of light, including that which we can’t see? Maybe one day we’ll measure these things. Maybe we never will. Maybe what we think of as “measurement” can’t capture it, and we’re too caught up in our own way of seeing the world to think of different kinds of measurements!

    Personally, I don’t think we know a damn thing and I’m not sure I trust anyone who thinks differently.


  4. In high school we were given an assignment to imagine life on another planet. Groups were set up to explore things like government, religion, shelter, family life… I’ve thought about that assignment many times since high school and find myself drawn mostly to the question, “What is their food like? Do they have anything as wonderful as chocolate?!” I don’t believe that was one of the offered topics for consideration.


  5. Ha! I think I would probably be with you in thinking about the question of food. It’s really one of the things I like best about life, so it would be a fun question of what it would be like for species on other planets. I’m sure everybody’s got something as wonderful as chocolate, although we might not agree if we got to try it!

    Frankly, it should have been one of the topics of conversation. I would say food is one of the more interesting options, especially when you bring in how they find/farm/hunt/gather/etc it . . .
