Why Haven't We Found Alien Life?

[@ianbattles7290]

On a cosmic scale, time/distance are so incomprehensibly vast, the odds that any two civilizations will exist simultaneously AND be close enough to facilitate meaningful two-way communication are close to zero. Even using our most advanced technology, it would still take longer than a human lifespan just to leave our own solar system.

[@Anthony-lf2kg]

Ian Battles ; god damn your comment is depressingly true. I hate to be a pessimist but the chances of us actually traveling to another star or planet outside of our solar system are so incredibly slim, especially at the rate we are going now with the vast majority of humans explaining the world around the by religion instead of logic/scientific reasoning. I certainly think we will make it to mars and have some form of colonization there but outside of that the future is looking fairly bleak. Apologies for the gloomy rant

[@johnhess1430]

Unless its two planets next to each other

[@Feedmaster420]

Given enough time we could colonize the galaxy even if FTL isn't possible.

[@throwawaywwwwwww]

Ian Battles The time is not yet incomprehensible. The universe is still young. And the incomprehensible distance and vastness makes it more likely for two civilizations to exist simultaneously.

[@vhawk1951kl]

presumably because you never lost it, leaving aside the high probability that there is no such thing. Mind you it might be behind something or underneath something which is generally where things that cannot be found are to be found. From where did anybody get the barking mad idea that there might be what is called "alien life"? Would it not be hilariously funny if there were one or two creatures that simply finding themselves on some obscure planet were content to meditate on the wonders of life, and were not interested in materialistic things and did not want to get anywhere?- they might b Buddhists or have some other strange religion. That possibility does not seem too cross the minds of the more given to fantasy.

[@1112viggo]

Why is it always assumed that life must meet the same requirements as we know it on earth? for all we know there could be creatures who for instance dont eat drink or breath anything, but rather get their energy solely from thermal energy or radioactivity. We can never asses the general probability for life in space at all until we find and study the lifeforms on at least half a dozen different inhabited planets, if there are any.

[@onewhostudies6856]

Because people on earth have witnessed human aliens that look just like us. The are the Plejaren and their ancestors mated with primitive earth people long ago.

@lil Clock lmao i hardly think scientists would be that picky if they thought there actually where a chance of finding life completely unlike what we know. Its just hard to search for something you have no idea what could look like and that is kinda my point. We might be very surprised when we finally do find alien life^^

[@1112viggo]

@@onewhostudies6856 that could very well be. I mean those ancient aliens guys are completely full of shit for sure, but their overall theory could be right. its certainly one of the best explanations for religious stories and practices that i have heard.

[@gideonfuterman7265]

I could be wrong, but I think it's that they have eno clue what life would look like unlike our own ( and no ways of deciding if it's life or not, nor the conditions it would need to come about) so the only way they can be sure they have found life or are looking in a possibly right place is if it's similar to our own

First, if a civilization had the technology to find and contact us, i really doubt that they would have a reason to; they would, probably, be god-like to us. Besides, if the universe is as populated as the statistics suggests, we are just another starting civilization with hardly any potential for any kind of argument. Therefore, I am sure that the probability is quite low of any super civilization within our galaxy find us in this little corner, have a similar way of thinking and communicating , have a reason to contact us, and decide that this reason is worth the resources. Remember: We probably look like smarts squirrels with basic knowledge of the universe and an inflated ego to a mere type 2 civilization.

Personally I think war is a fundamental part of civilisation, unfortunately. A war to sustain memory, a war against chaos, a war for the environment and ecosystem, that is to make social equality and life quality for every living being . War to protect the society that is "good", and to work is good . But the biggest paradox of the Eons, is that everybody fights the "good fight" . Hermes Trismagistus says : There is only one religion of God, that is to be good . And Everything in the universe is good. but it also creates volcanoes, meteors and exploding suns. Is the flame good or bad, at a distance its warm and cosy, close its burning scortch . Flame is good and bad, at the same time . Looking at the ancient records, war is usual also between the gods, and other beings, where was it ... Bagavad Gita from india . If you forget war, you loose .

And that may be fundamental to humans along with a long line of other creatures on this planet, but we do see plenty examples of lifeforms for whom war is completely unheard of. Life on earth are either prey or predator, and our most intelligent species happens to have evolved from the predator category, had intelligent life evolved from say dolphins instead of primates our brains would be wired different and we would probably project our own peaceful nature onto potential aliens just as we mainly project our violent nature on them now.

personally im one of those people who dont want to intervene into nature like for example IF we make it to a type 3 civilization and then find another species thats going trough the 1500 period & we show ourselves to them they might just start to worship us or changing whole biospheres or planets doesnt seem right destroying or terraforming dead planets doesnt seem bad on the other hand, after all they dont have life on them

[@unixone7558]

+PBS Space Time I had a personal answer to the Fermi Paradox. We are looking for intelligent life by scanning for radio signals, ones that our computers would recognize, but what if that's the problem? All of our computer systems are based off of binary (more-or-less), but we don't know if that's the only method of electronic computation (or even if it's the most efficient). So, what would be the chances that any other nearby intelligence would invent a computer base code that is binary? They could make systems we don't understand, systems that would just be picked up as stellar noise by our radio telescopes. It may be that life is abundant, but that because of differences in development it's almost impossible to notice. Tell me if this makes sense PBS. I'm open to being completely wrong.

[@AlexKnauth]

+Unix One I partially agree, but I also believe that binary makes sense, and that it could easily be discovered again and again independently by different civilizations. Unlike base ten, it's not completely arbitrary. It's the smallest base that allows numbers to be represented in log space.

[@unixone7558]

Alex Knauth I never said it that no other civilization could develop binary, I just said that seeing as it isn't the only computational method, there is no telling where those other binary civilizations are. If any civilization with technological advanced enough to communicate through radio signals was near earth (and my theory is correct), then it's apparent that no binary civilizations are within reasonable communication distance.

[@williamskinner2732]

One reason we do not see evidence of intelligent life is because when we look into space we are looking backwards in time. If we look half way across the Milky Way we are looking at what was happening 50,000 odd years ago. For us to see any evidence of intelligent life this intelligence must have arisen 50,000 years in advance of our own (and of course pro rats for other distances). For this reason the possibility of communicating with any other intelligent life is only possible with life forms relatively close to our own as the transit time for any communication is twice the distance between them in light years!

[@zexisak4085]

William Skinner The diameter of the Milky way is around 100.000 light years. 100.000 light years is nothing compared to 10 - 12 billion light years which the age of the Milky way is.The furthest away you could see in the Milky way would even be shorter because we're not on the edge, but pretty much right in the middle of the edge and the galactic disk. But we can't see through our galactic disk because it's too dense, maybe in the future we could. So maybe the furthest away you can see right now in the Milky way is around 70.000 light years if you count my previous points, then that's nothing compared to the time life formed on earth, the age of our galaxy and the age of our universe.

[@zexisak4085]

[@johnlemon252]

Honestly the simplest explanation for why we haven't seen ancient alien civilizations is that we haven't been looking long enough and we're probably not great at knowing what to look for. It may be possible that megastructures are too difficult to be worth it, that interstellar travel is too resource intensive for any species to colonize more than a few star systems (especially knowing that'd probably be more than enough for any given species), and radio-signatures drop off exponentially with distance, meaning we would only be able to detect deliberate, targeted transmissions at any significant distance. Factor into that the fact that estimated solutions for the Drake equation tend to be in the ten thousands, while there are hundreds of billions of stars in the Milky Way alone, and we've only been looking for a few decades, it's no surprise we haven't seen jack squat, even if all our assumptions about the inevitability of galactic empires are true.

[@tonyennis3008]

Only a massive transmitter could be heard across the vastness of the abyss., and only then if there was a large receiving antenna that knew where to point. Consider we struggle to hear Voyager 1's 23 watt transmitter. The probe is 137 AU from Earth. All else being equal, if the probe were twice as far, it would need a 529 watt transmitter (and the ability to point it ever more accurately). At 1096 AU, the probe would need a 78 Gigawatt transmitter. That's about .3 percent of the way to the closest star. A larger commitment of antennae will mitigate much of the necessary wattage, but by how much? If a concerted effort of receiving dishes means our intrepid probe only needs 1% as much power, it would only need 780 Megawatts at 1096 AU. For the nearest star, square the wattage 6 or 7 more times. Perhaps interstellar warp drives are impossible. Perhaps multi-generational colonization ships are too impractical, too expensive, and too dangerous. In that case, we are all islands, forever separated by the speed of light. And that's the saddest thing. Maybe the aliens are out there, but they gave up on us 1,000,000 years ago.

[@twistedyogert]

But that doesn't mean humans shouldn't try. We could be the first beings to do it. Wouldn't that be awesome, to accomplish what no one else in the galaxy has done. We'd be legends. I asked my mother once a long time ago. "Would you try to do something even if no one else thought you could?" She agreed that someone should try.

[@Superfandangoo]

They did send a message in 1974, a scientist called Drake sent the Arecibo Message at an equivalent 20 trillion watts to the M13 cluster 22,000 light years away, we've some 43, 950 odd years to wait to see if we get a reply 😀

No, it is not. Our responsibility is to, in the future, help that life develop naturally, instead of destroying with our own. Example: Let's say there is a planet in a far away galaxy, orbiting a star. That planet is starting to develop life in early stages (very early) and we, explorers, discover that some kind of natural phenomena will extinguish that life. Our duty, as a sentient and intelligent species, is to help that life to develop. AKA, make it survive, evolute, and thrive. Now, sending single cells all over the galaxy so that it can fall in some moon or planet that has it's own ecosystem? That is not only retarded, it's malefic.

[@markyfilarky]

The aircraft was dark in the middle and orangish lights in each corner. We got out of our car and stared at it for a couple of minutes. It then started to get higher in the sky and all of a sudden it shot straight into the night sky . No loud sound or anything. Just a straight star wars like shot into the atmosphere.

[@wishywish025]

I strongly disagree with that notion that civilisation won't survive to the next century. For some reason, the West has always been obsessed with the idea of "the end times" and apocalypse. I find that this obsession is so strong that there are a great number of theory and hypothesis on the subject. One of such theory is the Malthusian idea of "Malthusian catastrophe" that purported back in the late 1700's, yet he was completely unaware of the extent technological progress and science could take us. Throughout history, similar predictions have been made and yet, here we are; 7 billion strong on this planet. I firmly believe that civilisation might and could stumble and results in a long period of "not going anywhere", i.e. the bronze age collapse, the dark ages, etc. But civilisation and humanity still survive, and will continue to throughout the next century.

[@xDosReis]

Aaron Humphrey You’re right…the great filter is already here. The tendency and ability to destroy is far too great; the propensity for reason far too small. Humans aren’t necessarily meant to succeed - we just exist. The whole financial system is a Ponzi scheme, when it collapses and there is a power vacuum, it’s not going to be the pacifists of every country who gain control of their nuclear weapons. We should just enjoy the time we have left. I doubt humanity goes extinct, but we need billions of people and advanced societal structures to fuel advancement to be galaxy colonisers. It would be impossible otherwise. Some would argue that large structures inevitably decay and break down given enough time. If time is the great filter, then will time not prevent us from advancing before it’s too late?

[@Zerepzerreitug]

I once read that the biggest obstacle for the emergence of technological life in water is the lack of fire. Fire is essential for the fabrication and manipulation of matter. Especially metals. Maybe underwater volcanic vents could do a similar job than fire. But it's a bit hard to imagine how a bronze-age octopus would forge a spear near a volcanic vent. ... You know what? Scratch that.

[@OljeiKhan]

+Shin Da "could a civilization ever alter the laws of its own universe?" "Could inteligent life develop underwater?" I have been thinking on these subjects for quite a while , but i don't have the scientific education required to answer them directly. What i've come up with is that intelligent life could develop underwater , in some cases it might be beneficial to be underwater , say if you are living on a rogue planet with a huge atmosphere , a thick icy crust and an ocean beneath , the deeper you are in the water , the more energy you can absorb from the planet's core assuming it's still hot of course. But still the pressure alone would heat up the water and supply at least some form of energy. But altering the laws of an entire universe? That would be an incredible feat , if any civilization could do that , they would rightfully become the "Gods" of their universe.

We may end up having to accept that we are the only "intelligent," species -- at least within the perceivable universe.

[@modmaiden6138]

[@meisterli]

It may be that intelligent life in the universe actually IS around us everywhere, but that they use some kind of way of communication that we have not yet invented. Maybe something akin to the "subspace" messaging in Star Trek. I'd like to think that some day, an inventor on earth will turn on such a device and be greeted by the relaxed tunes of space trucker radio. :P

[@garethdean6382]

+meisterli But that would also mean everything they do is undetectable. They're not messing with stars or building Dyson spheres or deliberately trying to message less advanced lifeforms.

[@Zerepzerreitug]

One doesn't needs to go that far. Just imagine aliens use strong encryption in their messages. If that's the case, then even if they use ordinary radio signals they would be indistinguishable from random noise for all of those who don't know how to read the messages. (source: www.theguardian.com/us-news/2015/sep/19/edward-snowden-aliens-encryption-neil-degrasse-tyson-podcast)

[@garethdean6382]

Arturo Gutierrez Of course they'd still be messages, which is different from no message at all.They'd be going from one place to another in a very direct manner. Encryption hides the meaning of a message but it's much harder to hide that you're sending a message in the first place.

[@Zerepzerreitug]

Gareth Dean Oh, but that's the thing. A well encrypted radio message is indistinguishable from background radio noise from space. I get what you mean, that efforts such as SETI are not looking for signals with meaning but for signals with signs of being artificial. Narrow and bright and in the radio frequencies were messages travel best through interstellar space. But such tell-tell features are exactly what strong encryption hides. You deconstruct, spread, randomize and ultimately hide a radio signal so that it doesn't looks any different than natural noise. SETI looks for _intentional_ signals. But we don't have any way of telling if the sky is not full of encrypted ones. And it only takes for aliens to have better encryption than us so we can never tell. Does it makes sense?

Arturo Gutierrez Aaah very true, very true. I had neglected that. Though that raises further questions such as why you'd want to encrypt everything so strongly. Related would be why we don't see other evidence of civilizations, Dyson spheres and the like. If the aliens are being so secretive... why? And what happens to newbies like us that blare our location for all the galaxy to see...?

[@cernunnos_lives]

Great episode. Thanks for your hard work. And this place is still a slimy place.

[@ShneekeyTheLost]

Here's another thing to think about... if something is, say, a hundred thousand light years away, then it takes a hundred thousand years for the light from it to get to us. So if we are observing it through a telescope, we are observing its position and status of a hundred thousand years ago. Even if we were to be able to 'see' it, a hundred thousand years ago there would've been multicellular life, but no sapient life. However, in the intervening time, life could have since developed sapience, we just wouldn't know about it yet. So, as the distance between us and a potential life-supporting planet increases, our ability to detect in real-time any developing sapient life also increases.

[@furbz8818]

That's assuming it has developed at a similar rate as earth, they could have had a couple billion years headstart

[@flatearth9140]

THERE IS NO INTELLIGENT LIFE OUT THERE OTHER THAN EARTH !!

[@MarcColbeckCCP]

Because of our weakness (no armour, small teeth, crappy nails, no venom, thin skin etc.) humans are cursorial hunters, and that makes us tenacious. Other intelligent life (think 'intelligent lions') might just be happy to stay on their planet and sleep 20 hours a day. Humans (and wolves, hence the cooperative relationship between us), as cursorial hunters, regularly make long term goals. Other life forms (with big teeth, mighty nails, etc.) might not be cursorial hunters and therefore might not do that.

[@myothersoul1953]

It could be that intelligence leads to a diminution of amour, teeth and all the other biologically expensive things need to to survive. Once a species can use their intelligence to build tools the selective pressure would be against incorporating them into our bodies. In other words, once lions start using flint axes they claws will start getting weaker.

[@MarcColbeckCCP]

Well, possibly, but that's not what we see in humans. We've existed as humans for about 200,000 years (if I remember correctly, I'd have to google it) and we've remained relatively unchanged during that entire time. Humans from 200,000 years ago look pretty much exactly like we do now, and we were cursorial hunters up until the agricultural revolution about (again, best recollection) about 5000-6000 BCE - that's about 97% of our history. Evolution takes a LONG time. There's no indication that we have changed physically in any sort of dramatic way subsequent to our modernisation.

[@myothersoul1953]

Marc Colbeck Behaviorally modern humans, indistinguishable from humans today, arose about 70,000 years ago. But our ancestors were using tools for a million years before that, plenty of time for a evolutionary effect. www.newscientist.com/article/mg21829124-200-stone-tools-helped-shape-human-hands/

[@MarcColbeckCCP]

That's an interesting article, thanks for forwarding it. However, it doesn't address the main point I was making, and that is - even with slightly advanced hands and wrists - we don't have talons, teeth, armour, venom, etc. If you plonk a human down in the Savannah and tell it "go hunt", the only way we really have to hunt something (before the invention of the bow and arrow, which was about 64,000 years ago - I looked that one up! - so AFTER we were 'indistinguishable from humans today') the only way they could have done it was to run the animal down to exhaustion and then bash it with big stones or clubs. And that's cursorial hunting. So, I stand by what I said: A fundamental characteristic of humans is our tenacity and capacity for long term planning, due (probably in large part) to the fact that we are cursorial hunters. Intelligent species that are NOT cursorial hunters probably wouldn't care about going to the stars. A planet with lion-like animals as the apex intelligent life probably wouldn't go into space, because lion-like-animals sleep for most of the day and don't engage in long-term, multi-generational projects. It's the old "We're #2, so we try harder" sort of motivation.

[@myothersoul1953]

Marc Colbeck Scrub Jays plan ahead. If they see a more dominate bird watching them as they hide food they will come back later and hide the food again. Planning is not the sole provence of cursorial hunters. Crows engage in activities out of what seems mere curiosity. So there other survival strategies that engage mental abilities that could be the basis of going to the stars. Lions hunt in pairs, they use tactics which so a form of planning and social organization is there. It's not like every lion hunt is successful, they have to be tenacious too. You could be right or wrong. With a sample size of 1 it's hard to tell what is incidental and what's coincidental. It's way to soon to settle on any theory.

[@shaunsprogress]

"Yeah! We can science anything..."

[@casienwhey]

My guess is that the probability that we made it to this state is actually very rare when you consider random type events, or the lack thereof that happened or didnt happen to make it possible. Like an asteroid hitting the earth about the right time in the evolution of mammals and not actually kill all those early mammals in the process (but wiping out the dinosaurs enabling mammals to take their place), early humans not dying off in various global famines (we came very close), the earth freezing solid for millions of years and almost, but not quite, extinguishing all life in the process, earth itself not being destroyed by the planetary collision which created the moon, the moons influence on the tides and on earth's rotation, a super volcano like the one under Yellowstone not destroying early man, the fact that we evolved at all to develop tools, speech, thought and especially abstract thought. When you factor all those things together its more amazing that we exist at all then that other intelligence life forms may not because it's an incredible amount of luck or good fortune for all of that work out favorably. Like winning a lottery when the odds are against you a billion to one.

[@reessoft9416]

This comment should have had a thumbs up weeks ago.Some good points about how lucky we've beenEven these days we have Jupiter around to save us from possible collisions with comets and asteroids.Comet Shoemaker Levy was captured by the gravity of Jupiter in 1994, and torn apart.A lot of people say that life must be inevitable because there are so many solar systems out there.That doesn't necessarily mean that life is everywhere though.If those solar systems are anything like ours then any Earth like planet may not have had enough time for (intelligent) life to evolve. Such planets would probably have had extinction level events, just like Earth, but may not have survived (as the Earth did).It could be the case that Earth like planets are very rare anyway.Almost every solar system that has been discovered so far is nothing like our own.Most seem to consist of a number of "hot Jupiters" that orbit very close to the parent star.It seems unlikely that intelligent life could arise in those star systems.

[@hamstsorkxxor]

+Gareth Dean I am always fascinated by the thought of a intelligent Cnidaria like civilization, arising in some vast coral-ecology. Imagine a subglacial global ocean on a planet orbiting a M-class star, trillions of years from now, near the end of times, long after the Hubble expansion have turned the universe dark. To them, there are no stars other then their faint, red neighbors, which is all that remains of their small elliptical galaxy. They would all the reasons to believe themselves alone in all universe. And then, on their first attempts to mine their nearby asteroid belt, they find something. A probe, from a far, far away world. Their finest scientists study it long and hard, until they realize that the lump of lead attached to it, once was uranium, used as a power source. They will know that once, when the universe was young enough for radioisotopes to be mined, there was place called "Earth" and creatures who could see a sky full of stars, using nothing but their eyes.

[@garethdean6382]

hamstsorkxxor Of course they may not know of radioisotopes or the element uranium, it would be curious to think on what conclusions they might draw. Until recently we thought there were a lot of Roman paintings of women holding brooms. They were actually female gladiators holding weapons. What would their alien civilization make of us?

[@matthewgrotke1442]

Thanks for this video and the conclusion that we are probably early. Some people (*cough Fraser Cain*) always bring up the bad talking point that the universe is "very old" and therefore it's unlikely that we are early-- and therefore that we must be alone because we'd otherwise see all the older civilization's Von Neumann probes by now. However, I feel that's simply a bad argument, especially considering that for life you really do need metals (heavy elements), and those have only become common in planetary systems in the mid-to-late Population I stars. The old stars had very little metalicity, and so rocky planets and heavy elements are infrequent with them. Therefore it's very satisfying to watch this video, in which you state the same points I have been fruitlessly making in discussions about Fermi paradox solutions. I think we are early and our contemporaries are a bit to far away to see at this point, and probably not much further along that we are. When you have millions of peers, yeah one of two of them would send out Von Neumann probes, but when you only have perhaps dozens of peers in the galaxy, the absence of probes is not a paradox.

[@nicodemusedwards6931]

[@ericsaullb]

+TheRetnet assuming that our observations of the universe are correct, the main reason its physics, the complex biochemical reactions inside any kind of life needs a easy way to transport nutrients and a stable way of keeping complex molecules, and chemistry its a bitch with that stuff, you cant have complex reactions of any kind past certain temperature limits because of exces of energy or lack of it

[@ericsaullb]

***** chemicals, most likely, but chemicals follow the physics rules, and one of the reasons of this its that molecules need certain temperatures to be able to react, otherwise they just hit each other so hard they can not form stable complex molecules as the rip apart with each hit, and the other is true also with extreme cold there is just not enought energy to make the bond between atoms

[@ericsaullb]

***** it got frozzen thereby no metabolic process was happening, in other words they were shutdown, with no capabitlites of moving, reproducing or anything at all

[@MegaParrotMan]

If faster than light travel is an actual impossiblity it would make sense than no species has colonized the galaxy. Also just because we think so differently doesn't mean that's a natural progression. All life could be like our lower life forms, with our way of thinking an anomoly.

Could it not just be that we're still subject to some kind of Interstellar 'Prime Directive' until we become either a threat to other civilizations, or mature enough to become part of whatever interstellar alliance enforces the directive? If we grant that there has been enough time that the galaxy should be teeming with life already, then surely this is a possibility? ...there's been enough time for the interstellar community to figure out that perhaps it's better to quarantine planets in their developing stages, observing from afar, rather than spring forth and show us the secrets of the universe - spoiling the 'game' almost?

[@KohuGaly]

+richardferreday or it might be, that they simply haven't noticed us yet. Perhaps our technological advance is extremely fast compared to other civilisations. After all, we are sending signals to space barely 100years. To randomly spot a signal in 100lightYear radius is hard...

[@julianemery718]

+richardferreday That's an interesting idea. Maybe like some sort of Intersteller list of each planet that starts to have life growing on it, and a countdown timer of how long the planet (and solar system) should be untouched.

[@richardferreday]

+KohuGaly Yeah it's a legit possibility. That being said, the rate at which technology seems to progress suggests that even a civilization a mere 1,000 years ahead of us could be so far ahead of us technologically that we wouldn't even recognise it's methods as technological. I genuinely suspect we know next to nothing about how energy works compared to what there is to know - Our technology could be so primitive that it doesn't even 'ping their radars' so to speak. They might not even be interested in radio transmissions... life could be so abundant that they wait for us to move past radio technology before they consider engaging in contact? And in that sense they could be invisible to us because we're looking for signs of other primitive technologies that are quickly moved on from. My moneys on we discover some more laws of physics over the coming century that open our minds to technologies we couldn't have even imagined before.

[@julianemery718]

richardferreday I mean, obviously there is still so much we don't know, and if science is anything to go by, whenever we answer one question, we get ten more to take it's place. I think we're asking thr wrong questions though. Let me explain. It's not actually that we're asking the wrong questions, they are correct, but we're just asking them too early. We're asking questions about things other then what is on our planet, because (and I only know this as a quote) we know more about space then we do of our own land and oceans. We need to learn about everything our planet has to offer before thinking of space, because if we do that, then we have no anchor of knowledge to base our cosmic exploration on. Or at least that's what I think.

[@KohuGaly]

Julian Emery Reasonable idea, but you've omitted one important factor. Many important discoveries about earth were made by observing the universe. Here is a list of few: earth is round - because of how sky changes relative to your position on earth (for example the angle of polaris over horizon). laws of gravity and motion - from the motion of planets on the night sky. Precise map-making of earth's surface (and precise pinpointing of position) - made possible by artificial satellites. They've also made long distance wireless telecomunication possible and also whether tracking/prediction. We would barely have any clue about those things without trying to explore the universe first (or at least our position in it).
