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.
+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.
It's hotly debated that microbial life crash landed on earth inside meteors which kick-started growth, in which case we are all aliens, that at some point invaded from outer space.
I can attest to these facts. I've spent the last few days pulling "weeds" KNOWING they are many species of aliens who are taking over our planet. Nothing stops them. Nothing kills them. They only return: faster, more dangerous, and more virulent. Why wont our government and our scientists start working on this problem before it's too late?
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 )

They will be looking for evidence of liquid water on the planets located in the habitable zones. It has been said that everywhere you find water on earth (a habitable zone planet) you find life.

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.
Once I read a short comic about an old scientist who made contact with an alien ship about to visit Earth. The aliens look exactly like big flies, and when they came to the old man's house they were immediately sprayed to death by his daughter. Before dying they sent transmission to their home planet that Earth is hostile to them.
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.
Huh? Lol u keep bringing up "time" as if it's a factor. It looks to me like they can travel through time, so time is irrelevant. It's kind of like you are making them sound like some dumb drunk driving aliens not in sync. I would have to disagree with this theory bc if they have the intelligence to defy the laws of physics, I think they wouldn't have a problem being in sync with each other.
@@Trey-ny7wh Time is a key factor, im not sure if you know what time dilation is man. We can reach the relatively closest stars without "defying laws of physics" the theory is totally plausible we just don't have the technology and materials yet. Getting rid of time dilation is theoretically NOT posible by any means, traveling to stars which are not ridiculous light years distance IS.

@UCt4556LWXpERkN2KarToopg No, but I do keep up with David Paulidas and The CanAm missing project.

No dog’s can ever find a trail from one spot to another. Hundreds of people who disappear from the National park’s and then they claim they don’t keep a list of people who go missing from the park’s which is a lie because they keep lists of fish that’s in their park’s, but not people!!

If distance affects the way we see visible light, for instance super far stars looking visibly red due to it being so far, how would that affect our ability to actually know what gases make up a planet’s atmosphere?
That's a good question?? ... I think that other elements emit rays or some forms of their presence from those stars and they can detect their spectrums.. like a barcode.

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 :)
+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"
+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.
I don’t think they would stunt our advances evolutionary wise. They’ve been here before and still visit today . I think thrust wsnt us go advance. I do think they study us the way we do animals but they’re not malicious. They are more advanced emotionally than humans . Humans destroy everything. Our technology is laughable
Our first actual space explorers, who will go "out there" searching for alien intelligences, will be androids designed to represent our species - not flesh and blood types. And the first "aliens" they will encounter (perhaps long after humanity has gone extinct, and earth has become a burned out cinder - perhaps much sooner) will almost certainly be other androids designed to represent some other intelligent life form that lives (or lived) on some other planet in some other part of the galaxy.
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 ??!!
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.
@@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.
It would give our civilization a big boost in consciousness if these types of people went through a guided heavy dose of the sacred psychedelics and look within.

Only thing that bugs me when people talk about potential alien life. They always say it NEEDS to have water, NEEDS to have oxygen. Says who? That’s just how life here on earth evolved, who’s to say that life on another planet didn’t evolve to breathe something else? Who’s to say that life somewhere else didn’t evolve to need COMPLETELY different things than what animals need here on earth?

Your talking about human habitation on planet earth. We have no idea what kind of environment, every single species of other terrestrial's would possibly need to thrive.
Well you have to work from the known to the unknown. The way dinosaurs look today is due to our current understanding of mainly reptilian anatomy. That being said you are correct and the way we expect dinosaurs to look may well be wrong.

I think Fred Hoyle got it right: "The rules of evolution are universal so when we finally encounter alien intelligent life, either (1) it will be so like us we will be disappointed, or (2) it will be so different the debate will not be about is it intelligent but is it life." 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.
The rules of evolution maybe the same but there are so many different factors that even if they are just 1% different could mean an entirely different civilization. To think that we are only that gorillas and apes are only 2% different than humans oh, so our 2% different look at what we have created. I truly believe that the bigger Factor will be consciousness and how far along or not along a species has become. For example if an alien life-form landed here today I do not expect that they would have any idea how to relate to us any more than we know how to relate to animals. The reason being we have egos imagine the species intelligent but void of ego they would be completely different

Do they factor red shift into spectroscopy... And how do they measure atmospheric composition when our best equipment can only see solar system sized features however many light years away?

Why look for life in space when we can't even understand each other? If we did find other civilizations, do we really think we could restrain ourselves from plundering & pillaging?
It's easy when it's physically impossible to interact in person.

They need to consider that maybe we live on a completely different frequency than other beings, and maybe we are unable to detect them at all with our current knowledge and understanding. Quantum mechanic's is closer to this idea than other fields of science.
We can measure frequencies from 10 to the 19 Hz, up to {or down to depending on how you are looking at it} 10−16 Hz < f < 104 Hz. If something lives outside that range we would not be able to have any meaningful understanding of, interaction, or communication, with it, even if it did exist.

I believe that life forms may exist in atmospheric conditions that are not inhabitable by life as we know it, making the limitation of possible planets increase.
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.
@Michael King ✋ I second that... This comment is undeniably an underrated one - it is a nod to just how unobtainable the capacity to even have the conversation of THINKING about TRYING to wrap just ONE MORSEL of a brain cell around this sort of thing... It's just - I have no words
Does anyone else see the similarity between Sara Seager and Jodi Foster’s character in “Contact”. She is obviously dedicated to the science and facts wherever it may lead…even if it’s nowhere.
Pure fantasy. There's absolutely zero proof of any such thing. It's a ridiculous notion in every way. Just you trying to be clever n get likes. Only 16 in ten months is proof. In other words you dint know what you're talking about
Except men like to feel powerful and there’s nothing more humbling than realizing how insignificant you are in the universe, so they’d rather spend money on overpowering each other.
Could have colonized a good part of the moon and have a start on Mars already along with building some good sized orbital structures and that's using the equivalent of tech developed since WWII. Don't need the greatest tech if the resources and manpower was spent like that. (However without such wars, would such technology have developed at a comparable pace? Unfortunate, but seems a thing with us humans and the frequent cross-over between tools and weapons, and other priorities may not have yielded certain advances.)
I think Sara is brilliant at explaining complex theories and did exceptionally well as the only woman on the panel. The men seemed to treat her as a curiosity which is rather misogynistic. We need more women like her in science and in media. Men dominating everything is boring because it is rather one sided and frankly primitive.
They aren't misogynistic, they are awkward nerds. Many times speaking a second language. Sara is a what if scientist. Meaning her, as well as these guys, are being paid decent money to waste money on planets that are forever unreachable. 500 ly is 500 years on a bus at light speed. I'll pass. I'll even give my seat to a woman. Don't forget to bring a towel. I don't give one damn about any aliens. I don't care about humanity and it's need to find out other life and ruin its existence. Our planet is becoming trash.
The only person stopping women from getting into the stem fields is women. We have had equality for a while now, even in the liberal Scandinavian dream scape where they made equality law; women still chose the same jobs, because they realized most of the jobs we do suck ass, and they know they dont WANT to do it.
If the sheer magnitude of the universe is accurate, then I have no doubt life is out there, however, "advanced" life I'm afraid is probably rare. By what we know about our own planet. Edit: but what an amazing subject. I'm so happy i live in a time when we can even talk about these things.
In 1952 we knew it in Washington DC. Everyone on the radar knew what it was except the pentagon. Gosh, just drop the pentagon in a hole so we can improve, not die.
Good forum, with one exception, the moderator. Sometimes very much on the mark, other times just stammering along, and worst of all trying to be clever, and failing. It's a serious subject, knock off the comedy routine.
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.
+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.
Interesting reply. I will think about what you wrote. I do disagree that intelligent life must not be autotrophic.

It's hotly debated that microbial life crash landed on earth inside meteors which kick-started growth, in which case we are all aliens, that at some point invaded from outer space.

Mark Collins sorry but distance and time ( which are the same ) has to solve FTL or dimensions jump) or forget any encounter.

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.
Once I read a short comic about an old scientist who made contact with an alien ship about to visit Earth. The aliens look exactly like big flies, and when they came to the old man's house they were immediately sprayed to death by his daughter. Before dying they sent transmission to their home planet that Earth is hostile to them.
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.
Huh? Lol u keep bringing up "time" as if it's a factor. It looks to me like they can travel through time, so time is irrelevant. It's kind of like you are making them sound like some dumb drunk driving aliens not in sync. I would have to disagree with this theory bc if they have the intelligence to defy the laws of physics, I think they wouldn't have a problem being in sync with each other.

If distance affects the way we see visible light, for instance super far stars looking visibly red due to it being so far, how would that affect our ability to actually know what gases make up a planet’s atmosphere?
That's a good question?? ... I think that other elements emit rays or some forms of their presence from those stars and they can detect their spectrums.. like a barcode.

At 58:00 Mr Davis mentions only one known example of life from non life but actually, thats only 1 POSSIBLE example.
Also, life can survive meteoric space rides but how the heck would it escape into the new environment without mechanical assistance?
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 :)
+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"
+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.
I don’t think they would stunt our advances evolutionary wise. They’ve been here before and still visit today . I think thrust wsnt us go advance. I do think they study us the way we do animals but they’re not malicious. They are more advanced emotionally than humans . Humans destroy everything. Our technology is laughable
It’s easier to fool people then to convince them they been fooled. - Mark Twain
Our first actual space explorers, who will go "out there" searching for alien intelligences, will be androids designed to represent our species - not flesh and blood types. And the first "aliens" they will encounter (perhaps long after humanity has gone extinct, and earth has become a burned out cinder - perhaps much sooner) will almost certainly be other androids designed to represent some other intelligent life form that lives (or lived) on some other planet in some other part of the galaxy.
Liar
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 ??!!
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.
@@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.

Well you have to work from the known to the unknown. The way dinosaurs look today is due to our current understanding of mainly reptilian anatomy. That being said you are correct and the way we expect dinosaurs to look may well be wrong. To get total population the best way is to physically count each individual but we don’t do that either and it seems to be working.
@@Brad-il9mw yes but we have evidence such as fossils and evolved offsprings of dinosaur to compare too. In the galaxy it could be life made from harder materials lives in pools of ammonia. Or that the vacuum of space is full of behemoth organic animals that are giant and live off of sunlight alone. We don’t know what we don’t know. Also our visible lights only see so much, there could be life at an energy and vibration level unobservable to us but present all around. Scientists can and should use these methods from earth of course, but reality isnt limited to it
@@Brad-il9mw The idea is that given an E.T. species were to be able to come & live on earth or already is here, would we even recognize it as being not from this planet.
93 billion light years in the universe. We can not travel one light year yet. It takes us about 37 thousand years to complete one light year. The answer is no we’re not alone and one of this days we’re going learn the unfortunate news

@@lysergic4169 the stories that these guys come up with are no different than the stories that religious leaders come up with! It's my contention that even the first religious leaders were also the first scientist and vice versa!
@@Myron_X They're not stories, they're talking about observable characteristics of exoplanets and stars using orbital telescopes, custom-built software and analyzing the way and frequency with which starlight dims. Taking precise measurements to detect exoplanets is not the same as telling stories or speculating about life in the galaxy.

I think Fred Hoyle got it right: "The rules of evolution are universal so when we finally encounter alien intelligent life, either (1) it will be so like us we will be disappointed, or (2) it will be so different the debate will not be about is it intelligent but is it life." 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.
Hi Bruce. I just wrote above how frustrating this panel of people are. I've just written at tbe top here why I am.
The rules of evolution maybe the same but there are so many different factors that even if they are just 1% different could mean an entirely different civilization. To think that we are only that gorillas and apes are only 2% different than humans oh, so our 2% different look at what we have created. I truly believe that the bigger Factor will be consciousness and how far along or not along a species has become. For example if an alien life-form landed here today I do not expect that they would have any idea how to relate to us any more than we know how to relate to animals. The reason being we have egos imagine the species intelligent but void of ego they would be completely different
Great host and interesting speakers. Thanks.🖖

I could never understand the life that is almost most definitly out there,obviously is more advanced by milleniums,that while we look for life ON other planets,no-one has even broached the possibility of life IN the planet's?
Charles Hood like in the anime Gurren Lagann, I’ve actually thought about that too and it would make sense if the surface of the planet was too hot or too cold but the inside was habitable for life
@@ciarraRizzuto9 great analogy
Do they factor red shift into spectroscopy...
And how do they measure atmospheric composition when our best equipment can only see solar system sized features however many light years away?
Like thats the resolution of the equipment that 'photographed" that black hole in that newer picture and even that's grainy with little detail compared to what's down on smaller levels like planets....
Why look for life in space when we can't even understand each other? If we did find other civilizations, do we really think we could restrain ourselves from plundering & pillaging?
It's easy when it's physically impossible to interact in person. And any civilization we interacted with in person would be not because we found them but they found us - we'd havee to hope that the social structure required to become that advanced and survive long space trvael would have removed any tribal urges that would lead to fucking us up
I'd lay money that we're already seeing it and just don't recognize it for what it is. I think life is the rule, not the exception. we live on life quite possibly, and some of the moons are children of some of the gods,er..i mean...planets. who knows such things?
Tic tack flying thing recorded in 2014 wasn’t it?
Great Job and I Love the title! My Corundum is exactly that. When I am in this certain area and take pictures and videos of things while there, the photos reveal and render a different image than what I see when there. The area has activity covered in ufology history and is what the photo renders is that what's really there. it takes a couple of days to see all the change that has occurred when looking at the original. I recently revisited the area and is so weird that is like its there we just can't see it! but the camera does. this is the second time , or is it abnormal for this to occur....
The univers is alive and the earth is too.
The universe is ancient, wise and has awareness, likewise the earth ❤️

Shouldn't they always be saying these systems have "at least" so many planets?
How many orbital periods don't align perfectly to give us a transit measurement with their star?
Hasn't it got to be much more than those that do?
Definitely, without question!
Agreed I'm not that well informed on how it works but yeah
There is a red algea like substance which has surfaced into existence throughout india. It has been coming down in the rain. This lifeform is spreading rapidly. It is being studied currently and has many anomolies different from common existing algea we know of. It just appeared is what many were saying.. it begs the question..where did it come from?
They meant to ask, "Would we recognise ET, if we saw one ?
We already have alien lifeforms around us, when we chose to acknowledge them. ☺️

They need to consider that maybe we live on a completely different frequency than other beings, and maybe we are unable to detect them at all with our current knowledge and understanding. Quantum mechanic's is closer to this idea than other fields of science.
We can measure frequencies from 10 to the 19 Hz, up to {or down to depending on how you are looking at it} 10−16 Hz < f < 104 Hz. If something lives outside that range we would not be able to have any meaningful understanding of, interaction, or communication, with it, even if it did exist.

I've seen two crafts, two different times. One was a 2.5 foot tall bell shaped one that appeared in my inground swimming pool. It shot a stream of water out of the side that arched about 16 foot over the pool and after about 20 seconds just vanished, slowly fading to nothing. Was october 2009. I could have touched it with my pool brush but was afraid of being electrocuted. I reported it to the FBI, but no response, oh well their loss, I feel very privileged to have witnessed it in my own backyard!
Sounds like your robotic auto-pool cleaner has a mechanical glitch or two. Time for a tune-up (&prob shld get the pool cleaner checked out while your at it!)

I believe that life forms may exist in atmospheric conditions that are not inhabitable by life as we know it, making the limitation of possible planets increase.
I believe both !!! Good call
Please open the caption of this particular video because some exceptional people like me could easily access the information on this subject too.
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.
That’s brilliant buddy
@Michael King ✋ I second that... This comment is undeniably an underrated one - it is a nod to just how unobtainable the capacity to even have the conversation of THINKING about TRYING to wrap just ONE MORSEL of a brain cell around this sort of thing... It's just - I have no words

Does anyone else see the similarity between Sara Seager and Jodi Foster’s character in “Contact”. She is obviously dedicated to the science and facts wherever it may lead…even if it’s nowhere.
If we had used all the money that we've spent in war, in space, by now we would have more than half of this questions answered
But those wars brought back natural resources and drugs, A1 missions
You would also be speaking Chinese or Russian.
Pure fantasy. There's absolutely zero proof of any such thing. It's a ridiculous notion in every way. Just you trying to be clever n get likes. Only 16 in ten months is proof. In other words you dint know what you're talking about
Except men like to feel powerful and there’s nothing more humbling than realizing how insignificant you are in the universe, so they’d rather spend money on overpowering each other.
Could have colonized a good part of the moon and have a start on Mars already along with building some good sized orbital structures and that's using the equivalent of tech developed since WWII. Don't need the greatest tech if the resources and manpower was spent like that. (However without such wars, would such technology have developed at a comparable pace? Unfortunate, but seems a thing with us humans and the frequent cross-over between tools and weapons, and other priorities may not have yielded certain advances.)
He does interuppting way to much causing the guess to lose their thought train, Your Fired.
If my favorite alien encounter story is valid, no way. “Roadside Picnic” by Arkady and Boris Strugatsky (can be downloaded as pdf)
I think Sara is brilliant at explaining complex theories and did exceptionally well as the only woman on the panel. The men seemed to treat her as a curiosity which is rather misogynistic. We need more women like her in science and in media. Men dominating everything is boring because it is rather one sided and frankly primitive.
Agreed
They aren't misogynistic, they are awkward nerds. Many times speaking a second language. Sara is a what if scientist. Meaning her, as well as these guys, are being paid decent money to waste money on planets that are forever unreachable. 500 ly is 500 years on a bus at light speed. I'll pass. I'll even give my seat to a woman. Don't forget to bring a towel. I don't give one damn about any aliens. I don't care about humanity and it's need to find out other life and ruin its existence. Our planet is becoming trash.

The only person stopping women from getting into the stem fields is women. We have had equality for a while now, even in the liberal Scandinavian dream scape where they made equality law; women still chose the same jobs, because they realized most of the jobs we do suck ass, and they know they dont WANT to do it.

“Will we know it when we see it?” So far I guess we do!
Really? Our own government has stated that we see it; but, we have no idea what it is.
