Alien Life: Will We Know It When We See It?

[@richardbennett4365]

We don't even know what makes a planet "habitable" other than the one example we know about. There could be lots of habitable planets that are in no way similar to earth.

[@paulwagner8638]

+Richard BENNETT true enough, so it depends what we mean when we say "habitable". It can mean "habitable to us" but can also mean "habitable to some form of life", e.g. if we find microbes deep under the surface in the moons of Jupiter would we say such a celestial body is habitable? Of more interest is what makes a planet habitable for *intelligent* life (perhaps "like" us, perhaps not), and it seems this is: (a) the presence of simple life providing the initial biosphere / food chain, etc (b) evolution surviving through the various contingencies that any planet is subject to over time (c) some "special" evolutionary contingency that permits a body form capable of tool use to accelerate brain development beyond basic survival needs to abstract thought It may be that (a) and (b) are relatively common but (c) is not. Jury is still out. Anyway, the first thing to look for is a biosphere, indicated by presence of elements (perhaps oxygen) or other compounds that are contrary to normal chemical balances that seek highest entropy states. This would indicate presence of some "organizing influence" that uses energy to create order from disorder. This to me is the broadest definition of life. We can note that earth-like creatures are oxygen-breathing but oxygen does not occur naturally as a gas in high quantity. It is very reactive and will usually bond to form compounds - H2O and C2O being notable. Presence of high quantities of free oxygen in any atmosphere is likely to indicate presence of some form of life. The same applies to other possible chemistry. We can also note that terrestrial earth-like creatures have body forms strongly dictated by earth's gravity. It appears that earth is toward the "smaller" scale of planet size and there may well be more planets that are "middle" size - somewhere between size of earth and gas giants like Jupiter and Saturn. The body forms on higher gravitational planets are likely to be more stunted (perhaps less amenable to effective tool use). Even if such planets had suitable atmosphere our bodies would not be strong enough to cope normally. We would be quite paralyzed and forced to remain prone. So whilst I suspect life itself may be quite prevalent I also suspect life "like us" is rare. Evolution does not have specific direction and results may vary. This leads me to also suspect any alien intelligent life could be very threatening. We humans have a tendency to fight other humans due to simple cultural differences so imagine how we would treat a totally unrecognizable but highly intelligent life form with little in common except control over advanced technology. Such differences may be irreconcilable with survival of the species. Thankfully cosmology has an in-built protection - vastness - separation over space and time, so hopefully there should be enough room for galactic colonization to proceed without reverting to conflicts.

Mark Collins sorry but distance and time ( which are the same ) has to solve FTL or dimensions jump) or forget any encounter. Made a calculation for a humanity 150000 years and then the age of the first planet which had intelligent life. Here on earth only one spices made into space. Sorry the numbers are nearly so little for encounter an alien ship, that drakes equation and Fermi the known paradox makes me severely sceptical ever to encounter intelligence, not circumstantial evidence because the atmosphere will change because of exhaustion etc. So far nothing. But life yes , alien encounter is highly unlikely. And I hope I’m so wrong. Information can’t be faster than light, and the expansion of the universe is beyond light speed. So these galaxies are moving away from us beyond the speed of light . ( the local observer )

1:02.00 that old guy has got it wrong..he mentions life forms living in salt, because the salt can absorb moisture from the air, and he calls it deliquescence...well he's a not quite right there. The common salts that are from these dried up seas are mostly sodium chloride. These sea salts are not deliquescent, they are in fact just hygroscopic, meaning that they can absorb water vapor, but not to the point where they keep absorbing it and become a liquid , that is in fact the nature of a deliquescent substance, such as potassium hydroxide, Zinc chloride, ammonium acetate etc. Subtle but important difference.

3:58 off the bat, and this may come up later, but i was watching a video by brian greene where he is talking about near light speed journeys with crews that expect those journeys to take a hundred, or perhaps hundreds of years, crewed by populations rather than a few. if that were to happen that crew would be on a one way trip, back on home planet the amount of time passing would mean likely their home civilisation would disappear, or disseminate at best, and if you sent out a hundred ships with a variety of journey times, those ships would be well out of sync with each other, what i'n getting at is that even if everywhere in the universe developed civilisations and sent them out on interstellar journeys, at lighr speeds, then everyone would be out of sync - perhaps none of the arrivals would occupy the same period in history, no one would be aware of anyone else because they occupy a different time line. maybe this is why we don't find evidence of life, they came and went, or they are still en route, but given the amount of "time" there is in the universe, we're just out of sync. and what i was going to say is, why planets? if you are a echnologically advanced civilisation capable of space travel, why would you live on a planet? okay search for "life" on other planets, but you won't find anything that has had space travel for any length of time.

[@paulwagner8638]

Homing in on the topic "will we know it when you see it?". If the history of life on earth is anything to go on, emergence of highly intelligent species took a long time, and if we can categorize humans in the last few hundred years as "technologically advanced" this is a mere cosmic blink in time. If other intelligent species arose elsewhere the probability is they did so many thousands or millions of years ago. That is, they would be vastly VASTLY more technologically advanced than us newbies. In other words, the chances that another species is "similar to us" is infinitesimally small - they will either be primitive life forms or vastly superior beings. SETI has failed to find any evidence of the latter, so we might assume, even if life is pervasive, the emergence of technologically advanced species is rare, but if they exist, they would certainly see us as primitive (in military terms it would be a no contest). They would also ensure we never evolve to be superior (the same way we would ensure chimpanzees never gained technological superiority over humans). Hence, if they exist at all, they will ALWAYS be our superiors. Are we prepared for that? Being alone has some benefits :)

[@paulwagner8638]

+James McManus sure...in no sense is progression limited to linear, Earth is a case in point where this has been punctuated and now could be considered exponential. Life has evolved for 3.5 billion years. There's no reason to assume that higher intelligence needs that long (or short). Imagine it took only 2.5 billion years so that this intelligent species had a billion year head start on advanced technology !!! Mind-boggling. But I would suggest that "less" to "more" more-or-less (excuse the pun) sums up what we mean by "advanced", i.e. from simple to complex (technology). And I think we can gauge "advanced technology" independently from our own past by using universal reference points, such as ability to apply technology by controlling the electromagnetic force (we have some capability), quantum mechanics (we are primitive), gravity (we are nowhere), and eventually bio-engineering and cosmic re-engineering to achieve control over the universe for our ongoing survival, At present we are a niche species occupying a tiny pond in the universe. We are adapted only for that habitat - our biology shaped by earth's physics (gravity, energy supply, etc), chemistry and biology (water, atmosphere and nutrients). This biosphere is a product of millions of years of organic life. Without life, earth's chemical composition would be vastly different and almost certainly lethal to an unprotected human. Hence our chances of finding another "earth" UNINHABITED are realistically zero. Only teeming diverse life can create the kind of biosphere we need . Of earth like rocks in space (i.e. no life) there may be many but they would be UNINHABITABLE without planetary re-engineering including creation of a biosphere. Big job on a far away rock. Of course life may be adapted to very different conditions and hence take a radically different form - ALIENS. This all leads back to my original point: - Worlds that are uninhabitable to humans can only contain no life, or quite alien life. We might hope these remain primitive as advanced aliens with very different biological needs will pose some threat. - Worlds that are inhabitable to humans must have biology. If any have achieved "advanced technology" they are likely to be vastly more advanced than us (a coincidence where we both reached the same point within few hundred, or even few thousand years of each other seems an infinitesimally small chance). - Some glimmer of hope is offered by intelligent life converging towards artificially engineered beings that are designed to adapt to a diverse range of conditions found in the universe. IMO this is the most likely path to "galactic societies"

[@cghkjhjkhjhvfghc]

+Paul Wagner I like your conclusion of artificially engineered life. I do not think we (life) can rule out the idea of our evolution from a biological stance to a mechanical one until we learn more. I also agree that SETIs lack of interesting discoveries are interesting in itself. SETI's reach is small though compared to what we have seen in Hubble an the VLT. I disagree with your use of probabilities of intelligent life being more advance though. Lack of evidence does not give us the ability to assert the contrary. Evidence of the contrary has to exists for us to assert it. There are simply two many unknowns at this point. Homo Sapiens have been around for 100,000 plus years. In light of how long what you or I would consider intelligence. You had some interesting comments though., thanks for your insights.

Because novels and movies always go for (1), he wrote a novel: "The Black Cloud" to illustrate option (2). It should be compulsory reading for anyone thinking about alien life/intelligence.

I truly believe that the bigger Factor will be consciousness and how far along or not along a species has become.

21:29....isn't just looking for oxygen signal in a planets light spectrum a limiting way of inferring that life is present ? After all Earth most certainly absolutely had life well established prior to the great oxygenation event caused by the photosynthesizing Stromatolites. Who's to say that the life we find, which is most likely going to be microbial, is also more likely to be anaerobic simply because that is going to be the primary energy source for microbes to use and evolve with, like bacteria using hydrogen sulfide, or even oxides of nitrogen ! Are we deliberately ignoring or discounting these types of scenarios simply because we don't WANT to find potential real estate filled with a poison atmosphere ??!!

[@pyronixcore]

Super late reply, but the concept is that complex life is far more likely to rapidly evolve to become aerobic than anaerobic because of how simple and easy it is to provide energy via oxygen. All complex life on Earth is only possible _because_ of the great oxygenation event you spoke about. Before oxygen, life was not able (as far as we can tell) to produce large complex life forms due to physical limitations of terrestrial biology and the chemical requirements for those complex structures. This tells us that if there is complex life out there, conditions might be more likely be similar to what we had than be much different. Since we're not looking for a world that has fresh juicy brand new life, but established worlds colonised by life with sufficient biomass to leave signatures, this is baseline of what we know to look for. Looking for one group of detections is easier and more readily quantifiable than searching the universe for any and every possible chemical and trying to draw loose conclusions on the random data.

[@psycronizer]

@@pyronixcore I'm not so sure...complex life it seems , is far LESS likely to evolve to become aerobic, judging on how long the Earth got along with it's anaerobes, after all, the transformation from anaerobic to aerobic atmosphere took millions of years, this didn't necessarily mean that aerobes had some tough time clawing their way up to become dominant, in fact it meant that the Earth simply became ever so more hostile to all the anaerobes, leaving a niche for aerobes with no competition, it was an inversion, from one system to the other. As of now, we have finally found evidence that given time, and the niche, anaerobes can and do evolve to become complex highly adaptable organisms just like aerobes do. On the face of it, Aerobic respiration is more energy efficient, but that's not to say that anaerobic systems also could not evolve to become just as efficient, there is absolutely no reason why it shouldn't, after all, oxides of nitrogen, sulfur, phosphorous, and highly reduced forms of sulfur like hydrogen sulfide are great sources of electrons for the electron transport chain in an anaerobic cell, the forces of evolution don't just stop because you are an anaerobe. If there is one thing that is certain, it's that we absolutely should not limit our parameters to what our experience of life is all about, life is, at it's very core, hardy, tenacious, adaptable, and above all, surprising.

The search for life is inherently limited by criteria used to define aliveness and, what we are really looking for is intelligent life that we could somehow communicate with but there might be many many forms of life that are aware to at least the degree humans but can we communicate to each other? We might not be able to communicate and they might not have autonomous individuals with language they might simply have roles in society based on morphism that could be gender or age dependent, they might be hive structured or they might not communicate at all and it could still be intelligent life. Add in lifespan, attention span, persistence of memory span, curiosity levels and, modes of perception: what happens to mathematics if the species sense is something like smell but limited to contact range? What would its thoughts be like, how would they "talk" to each other? What would it it think of are art? Or Euclidian geometry? Or, Plato's favorite shapes (that dude basically worshiped regular polygons)? We cant agree on a definition for life here but, we are trying to find it on other planets that litteraly hundreds to thousands of lightyears distant from the earth- A lightyear for those who dont know is 5,000,000,000,000 miles long, counting 1 number per second it takes 158548.95+ years to get to 5 trillion- finding intelligent life in the universe is a rather daunting task.
