This is actually one of the main reasons why we could be visited by 'the aliens' : If it turned out we were the most erotic things ever discovered by them.

The primeval drive to mate with us would be a huge motivation for increasing visitations, nothing else would bring them here.

It is also my worst scenario for a visitation, none of that raping the planet for resources, destruction of us as a species, just non-stop raping of every single one of us, no matter gender or age.

Kepler 186f Kepler 62f and Kepler 442b are the only good confirmed exoplanets so far according to Andrew LePage http://www.centauri-dreams.org/?p=32470

>>7084387
And just as an extra note, all of these stars are at least 500 light years away.

>>7084350
Probably not actually. TESS is a survey, it doesn't observe for particularly long so most of what it will find will be giant planets. Plato is a better bet for habitable planets.

>>7084249

We have nowhere near enough information to reach a rational conclusion. About all we know are:

1. Masses with huge error margins.
2. Rough positions within the parent star's "habitable zone".

You can't figure out anything sensible from that.

what a shitty world to live in

I won't live to see a real photo of the surface of an inhabited exoplanet ;_;

What's there to assume that humans aren't already on other planets?

Could we have been humans but with blue skin instead? Could we have had a 2nd brain if all requirements were met on Earth? Or is it because of Earth that we are like this?

Do you think that someone on another planet someone has blue skin?

>The SKA will be capable of detecting extremely weak extraterrestrial signals if existing, and may even detect planets capable of supporting life. Astrobiologists will use the SKA to search for amino acids by identifying spectral lines at specific frequencies. SKA will be able to detect the equivalent of an earth-type airport radar within 50 light years.

>ATLAST, using an internal coronagraph or an external occulter, can characterize the atmosphere and surface of an Earth-sized exoplanet in the Habitable Zone of long-lived stars at distances up to ~45 pc, including its rotation rate, climate, and habitability. ATLAST will also allow us to glean information on the nature of the dominant surface features, changes in cloud cover and climate, and, potentially, seasonal variations in surface vegetation.

Nope. 85% of people just won't care. 5% will freak out, but soon calm down, 10% will persistently deny the existence of the aliens.

It will literally change the world. I'm sorry life has been so hard on you that you think nothing will make people notice you.

not exo-planets, but,

Mars has some life forms, already proven, and my bet would be that something that orbits around Jupiter or Saturn would have life _of sorts_ most probably still unhindered by cosmological cataclysm, which could make have lifeforms more evolved (not intellience wise though) than on our planet.

but not like dr. spock life-forms, but nasa and such still would like sea urchins, water-bears, and moulds.

>>7089535
>It will literally change the world.
As compared to "figuratively" changing the world?

So tell me, how would it change the world?
Sure, if we could learn enough by listening in, we might make great scientific and technological advances, but the news of alien life won't topple governments, religions, capitalism or cultures.
It won't usher in a new age of spiritual or philosophical enlightenment.
Most of the people who will get really excited already believe life is out there somewhere.
We're not in a position to send anyone to another star, and even if we made contact with a sub-lightspeed starfaring race, it would still take at least 1000 years for anyone to show up here.

So... what do YOU think would happen?
What would change?

>>7089535
>I'm sorry life has been so hard on you that you think nothing will make people notice you.

ah well im sure that if they were intelligent lifeforms they would debate that.

it would also make all alien-worship cults go out and write/ buy a new bible. right?

>>7089623

You do know that if they're 500 light years away, each exchange in the "debate" takes a thousand years to make the round trip?

Please put the bong down, stop huffing the glue, and try to put together a coherent sentence about what you think would happen if we learned there were aliens living 500 light years away.

>>7089684

hmm, well, they could have a means of communicating to us, we broadcast our bible further than our space probes...

and alien worshippers, like mang, there are hundreds of millions, easy.

so if we find a broadcast that was sent 500 years ago, it would reach us, if they have like late night tv talking about bibles and asking for money, we would have some understanding of their culture religion. so like just to let you know we could communicate with aliens tomorrow for all we know, i mean that is why we listen for alien broadcasts, to receive them if they were sent out some time in the past, and we were to just pick them up now. the movie Contact is a really good example of this, it doesnt mean we would have to wait centuries to have meaningful communication, even if it wast *dialogue*..

>>7089698
>hmm, well, they could have a means of communicating to us
If we announce ourselves, they won't notice for 500 years, and their response would take another 500 to reach us.
Your great-x40-grandkids will be dead before any response to any question you might have.

>>7089698

There are only 4 religions with "hundreds of millions of worshipers": Christianity, Islam, Hinduism and Buddhism.

Yes, it does mean exactly that. If the aliens are 500 light years away, how are we going to get them a message in less than 500 years?

>>7089745
>If the aliens are 500 light years away, how are we going to get them a message in less than 500 years?

Thousand years is long time stagnation_anon-san, and our tech growth is strong.

Sooner than that we'd have acquired FTL space travel capabilities already, provided it's possible at all, and the ayyliums existence is played right as motivation enough to justify potentially centuries of 1960's level investment and inspiration.

The sole existence of the ayyliums is a very strong motivator, even if it didn't led to a terran unification right away it pose as a threat governments have to premptivelly deal with and would also greatly increase the incentives to private funding of space travel, even if it's multigerational (imagine the tech giants, jew conglomerates and largest nation blocs competing to see who would manage to build the first ship to make contact with the ayyliums and secure a trade deal in ayyliums gadgets/lifeforms/exoticresorces or even if they're a backward bunch no match for our advanced weaponry, be the first to rape/pillage/enslave them ayyliums and become emperor over a sentient race, commanding top notch earth tech with the added benefit of having all resources of a whole planet available all for yourself.
Think of the possibilities stagnation_anon-san.

>durr nothing will change
>hurr religion
Wow you are retarded.

Do you think nothing changed in the mindset of people when the Americas were discovered?

Do you not know how the pictures of Earth from space and the moon changed the mindset of people?

How are you so stupid to not notice how vain and foppish human beings are?

It is one thing to assume/believe there are aliens. If there is PROOF, than the game changes. A lot of the people are going to act like their action would mean something more. Like they are being observed. People tend to look for reaction, approval/disapproval, acknowledgement, be it from our dogs, other humans, or god or what ever. An alien civilization would be a "brand new kid" to play with. But unlike our pets that do not understand us, and god that doesn't respond, an intelligent alien civilization is something far closer to us than our pets or gods. Given enough time, they will respond and "come play" or we'll go there.

And if you don't think that will change the mindset of people, than you are a sad little excuse for a human being.

>>7089941
>Think of the possibilities stagnation_anon-san.
Assuming no FTL (and that seems to be a fundamental property of the universe), there's no trade, no reason to build space ships, and certainly no reason for an earth-bound country to launch a mission that becomes (effectively) an autonomous nation the moment it departs.

And if FTL is a possibility, why aren't the aliens here already?

>>7089943
>Do you think nothing changed in the mindset of people when the Americas were discovered?
Pretty much.
How many people abandoned religion?


>>7089943
>Do you not know how the pictures of Earth from space and the moon changed the mindset of people?

No "mindset change".

>>7089943
>How are you so stupid to not notice how vain and foppish human beings are?
Of course I've noticed, it's a big part of the basis for my argument.

> an intelligent alien civilization is something far closer to us than our pets or gods
No, quite the opposite.

> Given enough time, they will respond and "come play" or we'll go there.
A MINIMUM of forty generations or more down the road for a 500 ly distant world.

>And if you don't think that will change the mindset of people, than you are a sad little excuse for a human being.

>How big would be the impact of finding signs of life on a planet 500 light years away? Would it change anything?


It all depends on how the findings went on.

Suppose we comission a new device that is just good enough to pick up signals of an advanced alien race 500 light years away. We're not fucked right away, but we only have 300-400 years until our radio comunications and our own Arecibo event attract attention to us, after that it depends on how fast they can get to us (FTL or not). If they were advanced already 500 year ago they might spam several star systems by now and no longer be that far away.

If they detected our early radio activity and/or our Arecibo event and sent a deliberate message we're utterly fucked. It means they have spaceships/colonies nearby and/or FTL travel/communication. We'll become their bitch.

If we detect early radio activity or someone else's Arecibo-like event then we have the upper hand, but not by much. We'll need to observe their rate of progress to see if our own tech growth can reasonably surpass them by a large margin, learn as much about them as possible from this long range surveillance and then go engage them in their home planet, preferably peacefully but prepared for the worst.

If somehow we detect some low tech alien niggers (anything pre nukes is shit tier) then we can do whatever the fuck we want with them, as long as we don't take too long to engage.

>>7089829
Nope, they'll just call them 'The Fallen Ones' and call it a day. Then they'll probably go around thinking they're warriors for the Lord before trying to start a war.

Sure m8. All the environment activism that started after the picture of Earth from space? The fact that certain governments push for renewable energy(example: Germany), most(if not all) of hardware manufacturers push for "green" technology, electric cars and shit? Mere coincidence! I'm sure they are all doing this for profit and not just because, you know, the mindset has changed?

>500 ly
It could be 500 000 ly. Doesn't matter. It sets a fucking precedent. It gives fucking hope.

I bet that out of the 2 people you call friends, none consider you such. If you had the time to talk with actual people, who trust you to share their intimate hopes and dreams, you'd know what I'm talking about. It pains me to tell you this, but you live a sad life.

>>7089956

Spaceships will be built eventually, and even if there's no FTL just knowing there are other intelligent species out there would make NOT having at least a local spaceship armada and effective planetary defenses a non-option from a strategic point of view. The uncertainty would force us to build some defenses and explore more to assess possible threats, instigating expansion.

Even without FTL I don't think ALL rich and powerful organizations, countries and individuals on earth would refrain from building spaceships, and once the colonization of nearby moons and planets in our solar system allow for large scale manufacture in space it will no longer be optional in the same sense you don't have an option not to use the internet if you want to stay in business and stay competitive. Within the proposed timeframe, without FTL travel having centuries of preparation before any further contact with the detected aliens, we'll have to play it strategically and keep on continually expanding to farther and farther away stars, or risk being genocided. The mere existence of another intelligent species poses the possibility of our species being erradicated upon contact, and as such we'd need military means to assure diplomacy would be an option. Those means would have to include weapons of mass destruction distributed in all our colonies in a radius around our mother system and/or towards the general direction of the detected aliens in such a way that, if things escalate to conflict, we could use the weapons present there even sacrificing any such colonies to cripple or destroy any attacking fleet headed our way, buying time to reinforce.

Impossibility of FTL travel and knowledge of the existence of other intelligent races would imply the strategical necessity of expanding enough to at least have a sizeable defensive belt around our important systems, effectively turning our borders into a huge minefield punctuated with warships and antifleet planetary defenses.

>>7089956
>Assuming no FTL (and that seems to be a fundamental property of the universe), there's no trade, no reason to build space ships, and certainly no reason for an earth-bound country to launch a mission that becomes (effectively) an autonomous nation the moment it departs.


We'd just have to build space supertankers that would carry hundreds of years worth of planetary scale consumption of relevant trade goods. Set outposts and colonies to store goods along the way and in a few centuries you have a constant flux of resources travelling back and forth throughout a secured supply line, each crew doing just one or two relatively short trip between close stars.

Multigerational crews might not even be necessary if cryogenics are available and/or the travel speeds reach a decent fraction of light speed (time dilation makes the crew age comparatively slower than planet dwellers).

>If they were advanced already 500 year ago they might spam several star systems by now and no longer be that far away.
Sure, but then you're talking about detecting aalien life much less than 500 ly away.

If they're already living on Pluto, for instance, they could be here next year, but that's not the question at hand.

If they're actually 500 ly away, and there's no FTL involved, (which seems likely, otherwise they'd have found us long ago), we're unlikely to interact outside a multi-thousand-year radio conversation.
With our wildest plans for interstellar probes can barely hope to reach the nearest stars, and even that should take over a century.

Even if that were true, it would just make the discovery less controversial and upsetting.

>>7090070

http://en.wikipedia.org/wiki/Fast_radio_burst (2007-2015)

We HAVE been receiving what very well may be interstellar radio traffic as far back as 1974,
with a big newsworthy item about a month ago.
The general public hasn't picked up on this at all.
Because "the general public" doesn't care.

Oh, even if 10% of the people get really, really, excited, that's still 700 million people.
But a month later, the news will be generally accepted, and the knowledge will join the background noise of our culture.

>>7090125
>We'd just have to build space supertankers that would carry hundreds of years worth of planetary scale consumption of relevant trade goods.
You get right on that.
Let us know how it works out.
Project Orion shows that we have reasonable hope of constructing a single probe that might accelerate to about 3.3% of the speed of light.
Relativistic effects would be negligible, and it would take 15,000 years to go 500 ly.
Of course, that's assuming it uses all of its fuel for acceleration and saves nothing for slowing down at the other end.

>>7087237
Technically speaking it will be possible within 40-50 years with advanced enough telescopes.

>>7089525
Discovery of intelligent life in other solar system would boost efforts to colonize Solar System and increase space exploration.
Certainly not by 100% with all humanities effort, but I think significantly enough to allow us to leave Earth in some stable number.
However I doubt we will encounter communicative alien life, if anything these will be artifacts millions of years old with mega scale engineering projects involved.

>>7089956
>Assuming no FTL (and that seems to be a fundamental property of the universe), there's no trade, no reason to build space ships, and certainly no reason for an earth-bound country to launch a mission that becomes (effectively) an autonomous nation the moment it departs.

There are plenty of countries and organizations that for ideological, scientific or religious reasons would build such ships.
Also you are wrong that there is no potential for trade. If a solar system is located within 10 light years and speeds are high enough, even a 20-40 year cycle of trading can be envisioned.

>>7090005
A-any aliens would be advanced millions of years ahead of us, thus technologically we could not compete with them in any way.
B-any aliens with such advanced technology would be capable of detecting Earth and seeing its surface using hyper telescopes
C-therefore they would be aware of our presence since millions of years
D-therefore it means they are unwilling to communicate or not exist

>>7090480
>We HAVE been receiving what very well may be interstellar radio traffic as far back as 1974,

>>7090670
>If a solar system is located within 10 light years and speeds are high enough, even a 20-40 year cycle of trading can be envisioned.
If there's intelligent life in the depths of Jupiter's atmosphere, we could begin trade relations almost as soon as we make contact, but the question was:
>>7089217
>How big would be the impact of finding signs of life on a planet 500 light years away? Would it change anything?
So without FTL, it's a thousand year round trip at best.

And, there's currently no way for us to accelerate anything faster than 1/30 of light speed, and even that leaves no fuel for slowing down, so even your 10 light year distant trading partner is 300 years away.
It would probably be faster to spend a few decades improving propulsion tech, then leaving once you develop better engines.

>>7090666
>, but I think significantly enough to allow us to leave Earth in some stable number.
I doubt we'll leave earth early.
There are already plenty of people pushing for space, suborbital tourist flights are coming soon, and we'll probably get to "space mining" for resources as soon as it's economically feasible.
But even if additional interest does speed up an existing process, that's hardy "changing everything".

Yo when did we have 14 planets in our system? That's awesome.

>>7090682

NOPE.

Your definition of "possible" is far too liberal.

Still, if there are merely a handful of such structures in our galaxy, it's easily statistical that we've missed them. Equally it's a problem that if there are merely a handful, they may as well not exist, since we'll never get to them.

>>7090778
>Yo when did we have 14 planets in our system? That's awesome.
Ain't it?
I think they demoted Pluto because unless they changed the definition of "planet", modern astronomers can't say we even know how many planets we have.

>>7090781

Yeah I have to agree it's far more likely for what we thought could be dyson objects are actually dust rings orbiting and just other natural 'structures' made from light masking features similar to dust .

>>7090867
IIRC, the search for exoplanets has turned up what they're explaining as a gas giant with rings 200 times the size of Saturn's.
Possible gigastructure?

>>7090815
We have 8 planets and several more dwarf planets. There could be hundreds out there undiscovered. Pluto may have lost planet status but Ceres was promoted from asteroid to dwarf planet.

>>7090920
Ceres had planet status at one point as well IIRC

Not trolling, my own Googling turns up nothing presently feasible any faster than Project Orion.

If you know of something faster, please post a link.

A mature Dyson Structure should be very obvious. Remember, many of the substructures used in the overall cloud, swarm, ring or whatever, will be made of refined materials. These will produce occlusions that will also alter the spectrum of the parent star in highly unusual ways... and I'd say "utterly unique" ways. Metals, ceramics, gases... all of these in such a mature Dyson Structure will produce a grossly different spectrum, which our scientists would be knocking their heads together to somehow explain using natural processes.

But again, Humanity has only really seriously examined about 1 to 10 million stars in our own galaxy. We have about 100 billion stars. Our sample size isn't large enough to find a handful of Dysons.

But what's the point, anyway? Anything further than the average stellar separation of 5LY away is essentially impossible for Humans to reach via vehicular travel. It just takes too long to reach. So even if we found a rare Dyson Structure around a star as "close" as 200LY away, reaching it using probable technology would require a multigeneration spacecraft that would take thousands of years to reach the destination. I fail to see the point of even looking in any detail, considering that surveys of "near" stars (within 6LY) are fairly complete and show no such Dysons or anything else that's artificial.

>>7090920
>There could be hundreds out there undiscovered.

Pluto is about 40AU from Sol. The Oort Cloud runs from about 5000AU to 100000AU. At the furthest extent, it's 2500 times farther from Sol. That's a massive volume, which even constrained to the plane of the ecliptic, is over 6 millions times larger than the volume in the plane within Pluto's orbit. Fleets of jovian masses could be out there for all we know. And I know of no serious study that's been undertaken to examine high-parallax occlusions of starlight within our ecliptic plane, which is about the only sane way to detect these sort of Sol-associated masses.

One thing which we'd need to calculate is the "Hill sphere" for Sol with respect to the interior mass of the galaxy.

No, it's simply me NOT being delusional. There's no point in exploring places where you have no intention of visiting. Finding another civilization 200LY away is pointless, since we'll never go and visit it. And if communication is your angle, then we would have heard from any such civ by now. So there's no point in 'looking' for what's obviously not there.

To a /sci/duck, space exploration is essentially a religion. There's no logic to it, and you can't use logic to find reasons against it. The neckbeards simply BELIEVE.

>>7091163
>Finding another civilization 200LY away is pointless, since we'll never go and visit it.
Yeah, and studying fossils is pointless, because they're already extinct.

Do you have any idea what it would mean to make contact with an extraterrestrial civilization? Even if all we could do is send them messages that would take 12 years to get there, it would be revolutionary for us, just to see another instance of a life-bearing planet. Right now we're sitting on n=1; it would be very useful to compare and contrast with another.
Science isn't about "what's the use of this"; it's about "let's find out".

Too bad for you that is not what scientists say

http://home.fnal.gov/~carrigan/infrared_astronomy/Fermilab_search.htm
The search focused on a temperature range of 100 to 600 °K leaving about 6521 sources. No cut was made on proximity to other sources. By doing this partial Dyson spheres were not ruled out. As noted on the Dyson Sphere look-alike page there are several natural surrogates that are difficult to rule out. Several cuts were used on the LRS sample to focus in on a Dyson Sphere signature. These included temperature, classification, and visual scans in SIMBAD. This led to a sample of 17 weak and ambiguous candidates..

I explore places I will never visit on Internet all the time, like Tibet or Calcutta.
We could explore alien planets as well using telescopes.

Why? There is no law forbidding this.

>>7091044

So something going faster than 1/30 than speed of light.

>>7084249

One with cute space aliens that are always horny and dtf. :^)

>>7091163

this is fucking retarded. by your logic, what's the point of any observation at all? why bother exploring black holes? understanding quasars? tracking where super novas occur? we'll probably never 'visit' any of those either ( in the reasonably near future at least), yet just observing them has offered a huge jump in understanding how the universe works, which, would you look at that, happens to be the entire fucking point of science.

we may never visit an alien civilization many light years away, but detecting them and understanding the planet they live on, even at a distance, would answer some pretty fundamental questions of life. at the very least we could understand whether they were carbon based, or if there are other chemistries at work, what their solar systems are like, etc etc

>>7084249


Silly anon, we are alone in the universe.
There's no life anywhere else.

If aliens were found military budgets would be reduced, science budgets would increase beyond peanuts and it would have a huge effect on people's psyche. Think about it, just knowing we aren't alone.

>>7091319
>So something going faster than 1/30 than speed of light.
Jesus, what is it about this thread that brings out all the stoners?

I don't know of any technology we have that can accelerate a ship/probe any faster than 0.033 c.
If you know of such a thing, please provide a link.
Otherwise, even a race only 10 ly away is at least a 300 year journey, and a 600 year round trip.
And again, this is still overly optimistic because the Project Orion design doesn't save any fuel for stopping at your destination.

FFS! That's a link I posted earlier.
That's where I got the 1/30c value!
The same page does mention even faster speeds (up to 0.8c), but these all involve theoretical energy sources we can't yet engineer (fusion, antimatter, etc).
