will be only bureaucracy. A few years back we took a look at alien First
Contact scenarios and we came up with 9 scenarios those might fall into, though fundamentally
you’ve got three basic forms that can take. They come to us, we come to them, or we bump
into each other out there. Today we’ll be focused on that first one,
and specifically where they’re trying to contact us, as opposed to us simply noticing
they exist, as would be the case with picking up some signal not intended for us or some
trace of their existence. This doesn’t mean they’re necessarily
landing in full view of the public with some saucer that disgorges little green men. Indeed as we’ll see today, that’s not
a very likely first contact scenario, and if they did land, we’d likely expect the
ship to disgorge something that looked quite human, as in many cases that would be the
most logical thing to do. But we can’t simply ask what the most logical
means of first contact is, because there isn’t one. Rather any given first contact would depend
on what the motivations of those doing the contact was. As an example, a hostile species that simply
wanted us dead would likely make contact with what we call a RKM, Relativistic Kill Missile,
or rather a volley of thousands of them hammering Earth so hard and fast that the contact would
last mere moments and take the form of bright expanding shockwaves – Game Over. Not the most illuminating of first contact
scenarios for learning about an advanced civilization, although I suppose in a literal sense it actually
is due to the sheer amount of light and radiation involved. On the other extreme, first contact might
come in the form of a radio signal in plain English saying “Greeting humans of Earth. This message comes to you in peace Tune into
Frequency X for an overview of basic Galactic information and detailed instructions on creating
a Galactic Internet link so you can access information files in high-bandwidth. Welcome to the Galactic Community.” Which would certainly be a nice message to
receive, assuming it’s on the level, honest and without any particular malicious or mischievous
motivation. But wouldn’t it immediately require asking,
“Why today? Why a century after we had radio? And why by radio anyway?” Anytime we get contacted we’d have to ask
“what has changed?”, assuming they knew of our existence prior to contact and the
message was meant exclusively for us, as opposed to us discovering a civilization far away
because our telescopes got better. Though that could be an example itself, if
they are reluctant to contact primitive worlds, but keep an eye on them, they might see such
telescopes getting built and say “Well, they’re going to detect us soon, best do
it on our own terms”. You might think it ethical to leave young
civilizations alone to develop without your interference, but once they have the technology
to explore space, they’re going to bump into the wider galactic community, and pragmatism
says you’d best go say hello soon, before they randomly bump into who-knows-what and
panic. That’s exactly what the pragmatic Vulcans
did when humans first developed warp in Star Trek: First Contact, and becomes Starfleet’s
basic policy eventually. So that’s an example of a way that development
on our side could drive first contact, but changing circumstances on contactors’ side
could also be the reason. Some interstellar empire that nominally controlled
the space Earth was in changed policies or ceded control of that territory for some reason. Now folks can contact or visit Earth who were
previously unwilling or forbidden to, and it has nothing to do with anything humanity
has been up to. As another example, if some neighboring third
civilization is getting aggressive, you might make contact earlier than ideal to give the
natives a chance to prepare, perhaps even lend them a hand in the form of military hardware
or a team of lawyers. And for that matter, it might be one’s own
aggressive civilization they’d want to give the natives a fighting chance against. Which is another thing to remember on this:
you are pretty much never going to be dealing with just one isolated group, Humanity and
Civilization X. While it’s quite possible, even without
faster than light travel, for a single species to colonize out from its homeworld to cover
the entire galaxy, it would be rather peculiar for them to have done so on such a recent
timeline to our own emergence. It’s being fairly conservative to say that
astronomical conditions would have permitted civilizations to arise only in the last billion
years, and galactic colonization timelines shouldn’t take more than a percent of that
time, ten million years – so why now? The odds of only two such species, them and
us, arising in that same period but nobody else doing so in that billion year period
would be 1 in 10,000 and frankly even such ‘good’ odds rely on assuming life couldn’t
have arisen much earlier, which it almost certainly could have, and that civilizations
not only never get faster than light travel but colonize quite slowly even by subluminal
methods, and that we only need to contemplate our own galaxy. Of course they might be way older, and just
been sitting around, but that raises some other concerns. First, why they sat around watching Earth
so long, many millions of years, and second, how they managed to stay “They”. Even ignoring the isolation worlds have from
each other at interstellar distances, by assuming faster than light travel, they’re not likely
to be homogenous anymore. It’s very dubious to assume a species that’s
been spread out over not only tens of thousands of light years of space but tens of millions
of years of time is anything like a cohesive civilization. Just living apart all that time around alien
suns, with no shared external threat to keep them unified, is going to make them more divergent
from their kindred on other worlds than we are from any other mammal, and that’s ignoring
all the high-tech options on the table like genetic engineering, cybernetics, uplifting,
and mind uploading, which should only hasten divergence. And so, even if in the beginning there was
just one great alien civilization out there, there would soon be many. Such being the case, anything they might do
in regard to us has to be seen through the lens of them worrying what their neighbors
or rivals might think. After all, they might have whole armadas of
ships that could single-handedly obliterate Earth, but so do their neighbors and rivals. They always have to ask what the response
would be, even to non-hostile acts like showing up with open arms and free technology. It’s conceivable that all the alien factions
would be fairly peaceful and friendly but frown on gaining allies and converts by what
they might view as bribery, potentially upsetting the status quo. We looked at that scenario a bit in Invasive
Aliens some months back. Alternatively they might be all guided by
some grand ideal. It’s not super unlikely that ethics tend
to converge to certain core and universal principles and if they did, then it doesn’t
matter if you can maintain cohesive galactic empire or not. For instance, all life on Earth shares a survival
impulse, it’s rather inevitable under Darwin and we’d expect that to be Universal, and
most ethical ideals can trace some connection to our various biological impulses plus various
reasoning, or rationalizing. I think it would be quite a jump to assume
every species out there believed in life, liberty, and the pursuit of happiness but
maybe not a huge one. More to the point, if societies tend to get
more rational over time it’s plausible they might converge to some shared ethics, particularly
if they tended only to arise from species that placed great value on curiosity and community
bonds, both of which would seem almost prerequisites for technologically advanced civilizations. Problem is, if they do, it’s kind of hard
to imagine they wouldn’t want to just show up on Earth and share those, or why they’d
think Earth in the year 2020 AD was better suited to it than it was in 2020 BC. Oh, they might figure we’d have an easier
time absorbing those principles now than then, but someone is bound to point out that 4040
years, 102 human generations, is a very long time to wait for better conditions to save
a little work. Humans are basically the same now as then
in terms of mind and body, so if it took a few extra generations to get the job done
then, it would still get done way earlier, by starting way earlier. On contemplation, probably even earlier since
it’s likely to be way easier to convert relatively primitive cultures to your life
philosophy. I dislike using analogies that imply primitive
cultures are like children compared to more advanced ones, but it applies to some degree. More to the point, regardless of whether it’s
easier to teach a 5 year old or a 10 year old basic ethics, you still start with the
5 year old because you don’t want them stumbling around hurting themselves or others any longer
than is necessary. So if they’ve got a Grand Ideal, you’d
need a reason why they aren’t sharing it as early as they find plausible. The exception being if that Grand Ideal is
non-interference, but you wouldn’t expect the lone, primary Grand Ideal of a civilization
to be about minor civilizations on their fringes, anymore than the various major nations of
nowadays focus their principles on what they should do in regard to this or that uncontacted
tribe. They might think it important but it wouldn’t
be the centerpiece of their culture. Even in Star Trek, it’s the prime directive
of their peacetime exploration group, Starfleet, not the Federation itself. It’s also not a policy that works great
unless everyone is on board. In the Trek Universe there is the Federation
and there are a lot of other empires who do not follow that policy. So it gets handwaved away why the Romulans
or Ferengi for instance haven’t just gone and contacted everybody the Federation hasn’t. In a case like that, if not everyone is on
board, then your Prime Directive has to be modified to not just not contacting primitive
worlds but guarding them or threatening your other neighbors who may contact them. That does offer one decently plausible scenario. Any species that has gone on the galactic
stage first might have felt terribly lonely and fascinated by various simple alien life
they encountered. Say they discovered a thousand worlds throughout
the galaxy that hosted some native life with a decent chance of producing a sapient species
sometime reasonably soon on galactic timelines, perhaps a million years. They might quarantine the space of say five
hundred light years around each such world, both to help ensure isolation and to be a
gift to that species when and if they achieve spaceflight. That’s quite a gift too, such volume is
generally going to contain around a million stars. Though not super generous on galactic scales
since it’s not even a percent of the galaxy’s available systems. If they tell any species that shows up to
keep their grubby hands out of those protected spheres, or else, they probably won’t have
to work hard to keep that as an accepted policy. Fight all you want over any remaining worlds,
assuming we haven’t claimed them ourselves, but keep away from those tiny bubbles. And to anyone operating on the galactic stage
that is a tiny bubble even if it contains a million suns. Of course all such things are relative, and
if we’re going to contemplate Elder Civilizations who operate on multi-million year timelines
and multi-billion star neighborhoods, creating large protected bubbles, one could argue something
like our expanding Universe might be an intentional way of creating pockets of isolation. You see such a world appear, with basic life
on it, and slap dark energy generators around to effectively isolate it from everyone else
by creating a massive expanding sphere of emptiness around them. Pretty over the top and I don’t think it
fits the observed facts about dark matter and energy too well, but it’s good to remember
that when dealing with massive and ancient civilizations the scale of efforts can be
mind-bogglingly huge even before factoring in any ultra-advanced technologies that might
break known physical laws. So too, since it’s unlikely any civilization
that’s managed to be around for millions let alone billions of years is terribly focused
on biology as a necessary component of life, you might dump civilizations into effective
pocket universes to keep them safe, be they ones you made by Clarketech or simply virtual
worlds you’ve uploaded their brains to. Key notion there is that a principle of non-interference,
or the Zoo Hypothesis, is plausible enough as a reason we seem to be alone, but there
are so many problems with the way we usually see in science fiction, and so many more pragmatically
effective ways. As we said, timing on first contact is going
to be about either principles, pragmatism, or current events – their current events,
not ours. When it comes to principles, the only one
that really fits the bill for waiting to contact folks till they’ve reached some cultural
or technological level is non-interference. So principles don’t fit too well as they
have probably got better options that are more likely to work for keeping us safely
quarantined. Such being the case, if we get a Hello signal
or a ship landing on Earth, it’s not likely to actually originate from what we think of
as our galaxy anyway, which is likely to be an illusion, or a bubble entirely gifted to
us. The notion someone might grant a whole galaxy
or Observable Universe to someone might seem rather ridiculous but everything’s relative,
and channel regulars already know just how ambitious we can be even without any super-advanced
technologies. If you accept things like faster than light
travel as possible, for instance, you have to consider dealing with species that not
only don’t come from our galaxy but don’t come from our Observable Universe. For all we know the whole Grand Shebang is
a trillion, trillion galaxies or more and somebody happened across Earth a billion years
ago, liked what they saw, and threw a giant dark energy generator back in time to isolate
our otherwise empty galactic supercluster from interference or shoved the whole supercluster
through a mega-wormhole into some new pocket Universe. You make first contact when that species,
us in this case, figures out how to notice that or look outside it. If they do contact you via signal or ship
though, they might go for that classic science fiction approach of landing a ship in Central
Park and asking to be taken to our leader just to make us feel more comfortable, part
of why I’d half-expect the ship to disgorge humans rather than little green men. You probably can arrange to have your ambassador
not only look like but actually be whatever species you are visiting, rather than shock
them with how you look and behave. Indeed, there’s a pretty good chance that
rather than being from species of billions of little green men who colonized part of
the galaxy, the galactic community is actually billions of Matrioshka Brains, giant megaminds
each powered by their own sun and running computational power in excess of a trillion,
trillion human brains each. Since a Matrioshka Brain is a type of Dyson
Sphere, you’d expect to be able to see such a community, or rather not see them since
anyone of those megaminds could pack brain uploads of every human who ever lived into
a tiny closet of vast computational castles, there is no reason to assume you and I are
actually seeing the real galaxy when we look up at that sky anyway. That’s another key concept too, if you’re
getting contacted by aliens then you should expect you’re dealing with something that’s
at least on the Kardashev-2 scale. See that episode for details about how mind-boggling
powerful such civilizations are even if they’re running with more or less modern human technology,
but short form, they outnumber you so massively that they’d literally have more anthropologists
than you have people. Indeed just a single K-2 civilization around
one lone star ought to be able to devote the equivalent of an entire University to studying
each and every single star in the galaxy while funding it about as much as we fund modern
anthropology. That means they know us better than we know
ourselves when they pop out of their ship or send a signal to us saying hello. If their goal is to traumatize us the least,
than they are going to have a good idea how to do that. Needless to say, if they have some other goals,
they are just as well-equipped to do that too. Heck they probably know us so well, and have
so advanced their own capabilities for neurology and psychology, that they could likely just
brainwash us or deliver such a well-polished salespitch that we’d be jumping for joy
at whatever they offered, even if it was mass enlistment to serve as cannon fodder in some
war of theirs, or as prey in their hunt, or as their dinner entree. I’m never quite sure why science fiction
likes to suggest aliens might want us for food, particularly since they could presumably
mass clone synthetic human meat from a few samples of our DNA, but I suspect if that
was their agenda they wouldn’t need to do it at gunpoint or even by deception. They could probably feed us such a load of
tripe that we’d be jumping for the chance to be rendered as tripe. You always have to ask, for any proposed alien
motivation, if there’s a way easier way to achieve the apparent goal. I can’t imagine why they’d want to put
humans on the menu at galactic diners, beyond there presumably being a market for exotic
meats. It would seem fairly likely many civilizations
would have taboos and an aversion to cannibalism or it’s alien equivalent, but even if not,
they ought to be able to just grow meat anyway and even if they prefer meat that was hunted
or slaughtered from something that had been sapient. I doubt that would be a universal taste, meaning
you’ve got to worry what your neighbors will do when they find out, again see the
Invasive Aliens episode for discussion of that issue. How about pragmatism as a reason for saying
hello now, not ten thousand years ago? Well, speaking of restaurants with exotic
menu options, they might have companies that franchise a lot and want to setup shop on
Earth. Plenty of folks would pay good money to try
alien cuisine, be it food or drink, after all as we noted in Parasitic Aliens, it’s
likely to be good stuff, Alien Beer is to die for. You might be wondering what we’d pay with,
being rather primitive, but trade is very adaptable and inventive, and this is an example
of when pragmatism could apply. The more advanced a civilization gets, at
least if human history is a good measure, the more exotic and abstract its tastes, both
literally for food and in many other things too. They might have services to offer that you
need to be fairly high-tech to desire or appreciate, same as you can’t sell video games to cavemen,
and there might be local rules about excessively priming the pump. No landing among Neolithic tribes and bootstrapping
their technology until they can desire and afford smartphones, no getting them to sign
over entire mineral-rich asteroids they don’t even know exist in exchange for a ten-year
subscription to Galactinet, and so on. We may also have finally started producing
a large quantity of something they value, which is likely to be something artistic or
creative. They might find our video games or movies
very interesting, and think they could be adapted as big sellers with more advanced
production techniques, and so to the surprise of everyone in Hollywood whose been making
films about them landing on Earth for years, they might go land right in Hollywood and
say “Take me to your Producer” As a whole, any given pragmatism-based scenario
always has to say what the goal is and why we just meet it now, or in the near future,
for it to work. It’s great if it’s the principle of non-interference
and they know you’re within spitting distance technologically of being able to spot them
with new telescopes. Or if you know they’re going to figure out
how to use and listen to some faster-than-light communications network you have. It also works if you’re not really into
non-interference but just don’t care much about other civilizations culturally and are
nice enough not to steal homeworlds, but suddenly have a motive. For instance if rules or customs of galactic
conflicts forbid establishing military or trade outposts on worlds or in their system
if the native species tells you to get out, but now they’re out in space and you need
to ask for a contract for basing rights. Then they find out you’ve been using Mars
as a spy outpost for a million years and kick you out. Or demand back rent. But that takes us to our third option, besides
principles or pragmatism, current events in the galaxy, or at least the stellar neighborhood. Things change, and a galactic map is likely
to have very fluid lines for things like borders or regulations or trade and defense treaties. Earth might have been under the shadow of
some empire for 10,000 years who just lost this bit of space or it seceded to become
a new realm of its own, or suddenly they need to buildup outposts in our area and they want
our permission or cooperation. Possibly out of ethical interests, or a long
time fondness for us who they’ve been quietly protecting, or possibly to keep their other
neighbors neutral or on their side in whatever conflict was brewing, if they might look ill
upon setting such outposts up without our genuine permission. Or it might be something that’s a bit of
a current events for us too, like a dwarf planet or rogue black hole headed our way,
and they don’t think its practical to try to do that without us knowing or even helping. “We need to disassemble Mercury to make
a giant cannon to blow up this dwarf planet headed your way” is probably the sort of
thing you aren’t going to even try to do covertly. Of course if they offer to do that, you probably
want to try to make sure that’s all the cannon is planned for, rather than, say, being
a big gun for blowing up their neighbors and you to serve as the fall guys when their armada
show up in our solar system to inquire about what happened and what your funeral customs
are. I always tend to assume alien civilizations
are courteous like that. Probably true too, you likely can’t make
a civilization without concepts like diplomacy and courtesy, especially really advanced ones
where offensive firepower is wildly disproportionate to defenses. That’s one more pragmatic reason for contact,
not saying hello when you know they’re about to find out you exist soon anyway, but doing
so before they make some horrible, self-destructive weapon or technology. By default we just assume any weapon we might
make in the near future would be no threat to them, but that’s a big assumption. It could be a lot of civilizations destroy
themselves early on with Suicide Pact Technologies, like we discussed in Late Filters last month,
and they show up before you do hoping to prevent that. Indeed you might have a galaxy devoid of any
ancient civilizations because this happened very frequently and only recently did anyone
manage to avoid killing themselves and now they try to pay their good luck forward by
intervening. On the other hand, we never want to get in
the habit of assuming technology always just keeps getting better and better over time. It might be that technology snowball’s very
fast and a 22nd century Earth can create just as good a self-replicating sentient galaxy
devastating super weapon as anyone else can. I generally roll my eyes at science fiction
that suggests aliens stay away from us because we’re hyper-aggressive, or only visit because
they need to enlist us in their cause for having that trait, because I tend to figure
anything that crawls its way up Darwin’s 4 billion year deep corpse pile is going to
pretty aggressive too, so that even if they are nice guys now they weren’t always and
wouldn’t likely scorn us for that trait but rather offer us a hand getting out of
it or just figure we’ll outgrow it. On the other hand, it could be they feel obliged
to race in whenever they find a species at about our level knowing we’re getting pretty
close to being able to build superweapons that are superweapons as far as they’re
concerned too. Though this, like so many other options, always
leaves that big question as to “why now?”, what changed with us or with them that makes
it better to say hello now and not a century ago, or ten thousand years ago? Not a lot of good answers that I’ve heard,
and again why I tend to assume there’s no galactic community yet and if there’s ever
to be one, we’ll have to build it ourselves, but the good news is, looking at means, motive,
and opportunity, if there is anybody out there with particularly nasty intent, they could
so easily have already taken action that we can probably conclude they either don’t
exist or are held in check for some reason and one which hopefully will keep applying
for centuries to come. There is one dark mirror version of the Prime
Directives of non-interference. Civilizations might have rules about not contacting
primitive civilizations, but it might be that it’s the galactic equivalent of fair play,
and once civilization hit a certain ‘age’ they’re expected to fend for themselves
against galactic threats, be it natural disasters like asteroids or alien armadas or abusive
trade partners and scam artists. You get out there and start colonizing your
local planets and mining your asteroids and they expect you to deal with stuff like asteroid
impacts on your own. Or for that matter, they might come land their
ships after you’ve started mining asteroids for space gold and present you a bill for
past protection services. “Welcome to the Galactic Community, you
owe us 4 billion years of back taxes”, and suddenly the hostile armada of homicidal alien
robots doesn’t sound that bad in comparison. While taxes and bureaucracy are likely to
be a feature of any civilization, trade is probably going to be the true cornerstone
of any interstellar civilization, be it with your own colonies or alien empires, and whether
that’s in raw materials or luxury goods or simply data and information. We’ll be taking an expanded look at the
notion of Trade with Aliens in our second installment of our new Nebula-Exclusive series:
Coexistence with Aliens, which is out now. Nebula, our new subscription streaming service,
was made as a way for education-focused independent creators to try out new content that might
not work too well on Youtube, and can be put on Nebula exclusively, though I’ll also
still be using it for previews and early releases too. And if you’d like to get free access to
it, it does come as a free bonus with a subscription to Curiositystream, which also has thousands
of amazing documentaries you can watch, on top of the Nebula-exclusive content like our

100 thoughts on “Welcome to the Galactic Community!

  1. Isaac Arthur,
    Would it be possible for you to provide a link to the new Nebula Streaming service you mentioned at the end of your video? I'm having trouble finding it for some reason. I would much appreciate it, if you could do that. I'm already subscribed to Curiosity Stream by the way, so I'm not sure if it will let me sign up for it over there again, in order to gain access to it.

  2. So the alien thing is easy to explain. Fermi paradox solution.
    You wouldnt kill your own grandpa right. And if space is shaped like a loop then so is time. So they cannot contact us because of the outside possibility that we are their ancestors, even if in the terms of panpermia from the last comet impact. It's impossible to know where you came from with certainty, assuming intelligence must be evolved from non intelligent reactions… I think things like galactic community's are going to be too hard for us to comprehend at this point. Too many nuances, and possibilities

  3. I wonder. I mean biology is such a rare commodity among the stars. So, I think that’s leaves out life ending warfare altogether. Resources, in terms of elemental material is easy to find in space. What’s not so easy to find is complex biology. So, in that sense we are safe, also from AI. Preserving life should be the intelligent response to finding it. Just saying.

  4. What has changed? To me, it's clear- we've only recently begun installing wireless infrastructure- If you want to contact an entire species that covers a whole planet, you don't just drop into a village and start training carrier pigeons… it's much easier and universal to be able to broadcast from orbit to modify wave forms than it is to find a person or small group that can be counted on to not withhold information for personal advantage.

  5. If i can think of one reason the aliens might legitimately want to wipe us out, is because of the dreck we routinely assault the universe with, beamed from Hollywood.

  6. I would be very disappointed if aliens landed and looked like humans. I want to see energy beings, silicon based life or some sort of intelligent space slime.

  7. All of the alien accounts that we had heard so far indicate that they have no ethics at all. Whatever suits their needs is what interests them.

  8. I love seeing Unity fly by, I hope there are some more Unity stories in the future 🙂 we last left them hopping out to the next galaxy as I recall!

  9. Don't get me wrong…I love Isaac Arthur , but it bothers me that he keeps reverting to FTL or just plain light speed when it comes to communication or travel. Light speed is easily breakable with the proper amount of Tech., and in my opinion communication done on a mental level is instantaneous . I believe that a high level Intelligence would eventually evolve to a point where communication on that level would be common place.
    I hope we make it long enough to get there….

  10. Alien Signal Message: Greetings people of Terra. We are from the planet Alderon. We send you this message of peace and understanding also, this message is brought to by, Big Zertons used spacecraft. Right now through 274582df4297.4 we have %25 off any spacecraft with 4.5 ly or less jump speed so come on down…. We have sent you this message to inform you that xr4ti law firm…….👽

  11. you touched on something that like to use in my own writing, galactic politics and conflict. I play with the idea that Sol and a number of other "local" systems and stars are part of an agreed upon neutral zone for a very long time and because of this, humanity simply hasn't been noticed until early experiments in FTL technology. Our sudden appearance then sparks a proxy war because both sides want to take sol under it's wing and either gain a buffer against their opponent or a foreword base with which to expand.

  12. We can’t even figure out how to feed ourselves and provide basic medical services. We also lock people up in cages for having plants.

    And we have the capability of wiping ourselves off the face of the earth.

    We’re a strange bunch.

  13. Thanks for hyping nebula.

    I've been in the comments of a lot of my favorite YouTube channels to try to get more creators on it. I doubt its made a difference but I REALLY want it to succeed.

    (Also you should get step back history on there, since you have worked with him)

  14. Just noticed this video on my home planet in a Galaxy far, far away. I thought you would like to know that we actually found humans a long ,long time ago, but you and your planet are such boring, worthless entities, we can't be bothered even using any energy to interact with you. And as for your entertainment – it's just rubbish.
    Though we do get a lot of giggles from commentary on the state of the Universe, like this one.

  15. Thank you. Such amazing graphics how? Space is full of debris, dangerous as you approach light speed, but is this useful too? Can you push against it as a form of propulsion. Love

  16. What if Earth is private backyard of some rich and ancient alien family with signs all around: "Private property. Trespassers will be shoot, survivors shoot again". And it just happened that homo sapiens evolved recently, but their soon likes us just like some human kids may like to have anthill to watch.

  17. So a thought just occurred to me during this episode. You mention often how great the scales are for higher Kardashev (read: any) civilizations. Like how any civilization observing us would have more anthropologists than there are humans. The scary thought that occurred to me is, would the "hunt and eat sapients" sub-sub-culture still be big enough to outnumber us, as well? From each civilization?

  18. Stop! No! It flies in the face of simple obvious reasoning. The Earth is perhaps one of the few planets in the universe with a biosphere, and some aliens are going to bombard it with missiles? That's, to put a strain on politeness, illogical! If they wanted to come live here, they would just land and either make contact or not. Aliens aren't dumb!

  19. Thank you for the boosted audio. I can listen to this in the shower with no speaker other than my crappy iPhone5 speaker. Almost any other Youtube video is hard to hear unless the fart fan is off. I can hear you with the fart fan and the shower going with the phone outside of the shower!

  20. When you look at the center of our own galaxy, the Milky Way, you are looking 25,000 years back in time.
    It took light 25,000 years to travel from the center of the galaxy to our planet. Think about that for a moment.
    If you transmit that image on an 'array of space antennas' the image would take…wait for it…25,000 years to reach us.
    This is the reason why aliens have never been to Earth and never will be. Space is just waaaay too huge. The end.

  21. I believe external intelligent life can not intervene until we come together as a society of intelligent beings. Imagine that aliens land in Red Square instead of Times Square? The panic, what would the US military industrial complex do? I think FoMo could cause anyone to launch a few nukes. What if they land in the ocean and only want to talk to the dolphins and the dolphins tell them, “some humans are cool, but most of them are greedy, blood thirsty, controlling assholes.”

    The point is this, until we have some unified “leader” the aliens can ask for, they won’t because then it immediately gives the notion that they’ve chosen a side.

  22. I know you try to focus on a single theme or concept in each video but I think that is a failing when thinking about these things. The end result of technological advance seems likely to me to make contact in the sense we think irrelevant.
    Ahh… It's too much effort to write this stuff out on a phone. Lol.

  23. Maybe our religions were alien attempts to share their values with us. Most of these religions suggest some sky God or angels from the sky, etc., etc. Maybe they'll show up again or have been observing us to see if we've listened….in order to judge us. If so, we're so screwed 😂

  24. Well we have to have bypasses, and your planet is in the way, the plans have been in the planning office in Barnard's Star for over 50 years. If you can't take the time to pay attention to local affairs we have no sympathy for you, Energize the destructor beams.

  25. 2:30
    Earth: (bottle of anti-matter over planet core) Uh, are you sure this is safe?

    "Galactic Community": Less talking, more Galactic internet.

  26. Well, is there a video on radiation shielding? That would be rather interesting, especially with the current research we've been having.

  27. So I have two questions I would like to ask on your series, I'm not sure if you've done videos answering these questions, I'm still binge watching them.

    The first is that if we assume that we as Humanity discovered an Garden world like Earth in our galaxy, and if we discounted travel time, how long do you think it would take for these planets to equate Earth in terms of population, industrial capacity, GDP etc.

    Second is that when you talk of invasions you often lampshade several alternate possibilities, but one thing I've noticed is that they may be in certain circumstances very time consuming. Politics in our day are often about the here and now, rather than planning for the future. Is an invasion more plausible if it serves as a quick solution for an alien species' problem. One that cannot be solved by bombarding the planet to dust

  28. "In the grim darkness of the far future, there is only bureaucracy."
    Sweet God-Emperor can I have planet-eating alien bugs instead?

  29. Seeing so many alien ships coming in the armada…. Makes me weak. That's too many ships… Too advanced tech. How the hell do we win against aliens in Hollywood.

  30. Ah yes, I remember that famous Einstein quote. If I have seen further it is only because I stood on the shoulders of four billion year high corpse pile

  31. This reminds me of a classic game called "Star Control" where a species called the Ur-Quan was so traumatized from being a slave race that they sought to confine every sentient species to their own home world as a way to "protect" them.

  32. In my book i did exactly that! Land a alien spaceship in Central Park, and the first being to came out from the ship was a human born and raised in Earth, but the aliens contact him in advance (i know, i know, is cliche, but the scene is always awesome).

  33. Harpazo is imminent

    Get your self a free ticket upward;

    “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”
    ‭Ephesians 2:8-9 KJV‬

    “Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:”
    ‭1 Corinthians 15:1-4 KJV‬

    “In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.”
    ‭Ephesians 1:13-14 KJV‬

    “For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. Wherefore comfort one another with these words.”
    ‭1 Thessalonians 4:16-18 KJV‬

    “Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.”
    ‭1 Corinthians 15:51-54 KJV‬

  34. If mankind is first, as we spread out, we will all become our own enemies. Especially if travel between each other take thousands of years.

  35. "Welcome to the Galactic Community. You owe us 4 billion years in back-taxes. "
    Looks like humanity broke the vase on that one. Kiss kiss, credit loss.

  36. Larry Niven wrote a short story (part of the Draco Tavern series) called "Assimilating Our Culture, That's What They're Doing!" The story is how the owner of the Draco Tavern comes to learn of how humanity has paid for all the nifty alien tech they've been buying: One species bought the rights to use what humans now use as medical tech to create replacement organs to make chunks of human bodies (up to a complete body from the neck down) as FOOD. The species in question was quite open about what they wanted the genetic samples from the expedition members for, and don't understand why humans find it all so distressing. They're man-eating aliens, sure, but they're polite, pay the agreed-upon royalties, are more than willing to sell their technology for the royalty money, and are saving a FORTUNE over shipping meat back from Earth. (Never mind that it never makes sense ecologically to ship large volumes of food from system to system, no matter how cheap your space travel is. As was noted implicitly in "The Moon Is A Harsh Mistress," you run the source out of biomass in the long term and their ecology collapses, with all the gory consequences of a complete ecological collapse, not to mention ultimately choking the destination with sewage. You can ship the sewage back, but it makes more sense to just grow your main foodstuffs locally to consumption.)

  37. I used "galactic community" as an analogy about a year ago when a missionary was brutally killed by a tribe of people living essentially a "stone age" life on an island in the Indian ocean called SENTINEL ISLAND. Some of the people who were friends and family of this slain missionary wanted the people who killed him put on trial for murder.

    The problem was that these people did not at all understand the laws of the outside world, barely even knowing that it existed at all. Their entire "world" was that island. Trying them based on laws from a world they barely even knew existed would be inhumane.

    The analogy I used was if aliens from another world came here and some frightened humans killed him and then got put on trial on some other planet for violating intergalactic law. It would be totally unfair since those humans did not even know there was such a law, and this is an entirely different level than normal "ignorance of the law" legal arguments.

  38. How much would a set of burnt DVD's of all your videos cost to you? I'm willing to pay10x that to not be locked into a subscription service.

  39. 17:28 Hang on… is that a CG bioprinter rendering your channel's logo in muscle tissue?
    You, sir, have the most talented fans ever!

  40. We tend to project our own anachronistic memes onto strangers.
    To make more sensible predictions, we to project post-scarcity, post-ignorance, and million-year-advanced.
    – Post-Scarcity means "they" do not need any physical resources – there is no motivation for exploitation.
    – Post-Ignorance means "they" know more about us than we do ourselves – our artistic artifacts are of no interest because they cannot relate to entities so primitive.
    – Million-year-advanced means "they" have evolved knowledge and interactions for a million years or more. In comparison, human "civilization" (city-scale collaborative organizations) have only existed for about 10 thousand years at most. So they could be as far removed from our point-of-view as we are versus a termite colony.
    – In "Childhood's End" by Arthur C. Clarke, the advanced civilization contacts Earth to ready us for a "rapture" transition.

  41. "Galactic Internet, huh?" types in search bar
    "Well, alien rule 34 it is then!"
    "Oh"
    "That's just a press conference"

  42. "Ethical" sensibilities like the Prime Directive stem from the naturalistic fallacy and the fact that its just easier to leave most primitive cultures alone. If you really think about it… it's truly ethical to help as many primitive cultures as you can. This idea that you'll "influence their culture" is, like I said, based in the naturalistic fallacy.

  43. To ease us into understanding the galactic civilization, they could send an avatar with vast knowledge about science, and a soothing voice, to outline some of the possibilities – purely hypothetical, you understand. Once he has, say, 500,000 subscribers, they'll know we're ready for the big reveal.

  44. Imagine going back in time and giving Hitler your smart phone. No. No way in hell is anything out there gonna want to risk talking to us.

  45. If a disembodied ball of Aliens pop up and give you a Lens then you know your really screwed.
    Of if a lot of smart cats come knocking you are also really screwed. Or if the Vorlons pop up you know the Shadows aren't far behind… I do love them aliens except for those pesky Klingons.. They are just way to silly.

    Now give me those ones from the childhood end novel that look like the devil and we all can rest easy at night.. LOL.

  46. You know what would be a neat comedy movie? A ship of aliens arrives on Earth, and the world is in awe of what knowledge they might give. Looking forward to bask in their amazing intelligence they must have and stuff. And the aliens are just basically the equivalent of goofy college kids. Chaos and hilarity ensues.

  47. Errr…passive detection methods are pretty much out pretty much the fermi equation is also our and anyone elses difficulty to detect.

  48. so what do you think secret high tech military activities might be like for level 2 and 3 species?…guess i gotta go re-watch galactic warfare vid.

    or think alien/alien clone spies infiltrating your secret military installations gonna be a thing? or gonna basically have to rely on mass of colonies and things to take a hit while you build counter weapons?
    galactic WMD's? do a vid on that yet?

  49. Wouldn't it be a thing if they arrived and their first message was "buy our products or we have no use for you".
