Alien Megastructures?

Recommended Posts

Oh please, if it were aliens capable of building such a thing. They'd know we were here. If we can find them, they can find us.  
I hope they come visit.

How would they know we were here? When the light we're observing now was emitted from their star, our most advanced achievement was the stirrup. They're 1500 light-years away.

Reminds me of that marsface.

1. Find something interesting in space.

2. Create Clickbait article online "OMG WTF ALIENS CONFIRMED"

3. Milk those clicks, make money with ads

4. After a few weeks suddenly it is just a rock floating in space

5. Noone cares anymore, wait for next "discovery" and return to step 1.

Presuming aliens with enough tech to seem like gods to us would give a shit about us.

Right. Most humans don't really think about communicating with ants for example. It's entirely possible aliens have travelled near enough to observe us but it's no more noteworthy to them than you walking by an ants nest.

Our planet with massive amount of liquid water is way more interesting than some bald apes.

If they want water there's no shortage of it throughout the solar system. The resources argument is one of the worse ones for why aliens would come here.

Also true. It could be that we are in some intergalactic backwater not worth visiting! But that would also mean that FTL travel might have another kind of upper limit if we are hard to get to.

bruh, Earth is like the New Zealand of the galaxy. No one knows about us and if they do know about us they consider us so small and insignificant that they don't give a shit and probably make jokes about how 3rd world we are at the edge of the galaxy with shitty technology.

I don't say they would transport it to their homeworld. Our planet could be a colony if planets with liquid water, stable thick atmosphere, magnetic field, proper temperatures and more are as rare as we humans think.

What if we are one of the most advanced species in (at least) our galaxy and one day we will be those bad aliens invading some poor civilizations?

Maybe, assuming they have biology even remotely similar to us.

Maybe we're part of a massive Galactic Empire and we don't know it. They just consider this part of this Galaxy "Theirs" but didn't even bother to look at every individual planet/star.

 

 

Just like a random ant colony in the US, they don't realize they're part of something called "United States" and think they're on their own, basically.

If we ever obtain the technology to do so, I'm pretty sure we would do something like that. Like a previous poster said, if we can't even consider us equal to someone of a different color from a different country. Imagine how we would treat others, especially when we're that technologically advanced. Either way, we won't find out - I'll be dead long before then..

It totally could be a huge amount of dust. Comet, no. But dust is a valid one.

Dust would glow on infrared and whatever that is doesn't.

This. Interstellar dust would give off an infrared signal at minimum. The lack of one here indicates something inert and solid.

Likely is just another unknown natural phenomenon, however the irregular dip in brightness gives the alien argument a bit more credibility.

People saying that they wouldn't care about us probably isn't exactly true. I'd imagine they wouldn't be all that different from us, assuming they evolved from some primitive organic material billions to trillions of years ago as well. They might be like "Hey look, there's something else out there" and might be fascinated with us like we are when we see animals doing what seem to be incredibly complex tasks for them. Or maybe some of them would simply want to meet us just to see what we're like, I dunno. If the positions were reversed, wouldn't you want to go check out an intelligent race of beings, regardless if they're primitive compared to you, just because it sounds like it'd be interesting? I would.

It's kind of like meeting a group of people, like a tribe in Africa or various other places of the world who have had almost no contact with any of the modern world. They're still intelligent beings, they still have a conscience, they're still just like us other than they've not advanced like everyone else has, and getting the chance to communicate with them and see how they live and  what life is like for them is very interesting for some people.

Here's the history lesson to be applied to what-if, we'd die. There's nothing in our history that shows good, atleast for the "natives", coming out of "aliens" meeting said "natives". Genocide, slavery, forced conversion, colonization, and don't forget those lovely diseases. Say you get past all that, now that fancy new alien tech fucks up your entire society and it becomes self-destructive. All those buffalo that were hunted to extinction? A lot of that was from increased hunting by natives, spurred on by interaction and influence with Europeans, not just European settlers killing off buffalo. We don't want to, or atleast shouldn't want to, meet aliens. It will end badly for us.

Well, one can hope that if we're visited by aliens, they'll have morals... hopefully. Chimps are said to be possibly the 2nd most aggressive and violent living species of primates, take a guess at what's the first. So again, one could hope that these aliens would hopefully be a little more understanding and have less psychopaths than humanity does.

We just have absolutely no idea. Morality is so culturally inclined and influenced they could have God knows what for morality, if they even have such a concept.

Imo the chance we meet intelligent AI instead of aliens is vastly bigger, good AI is immortal and far more suited for building mega structures or traveling vast distances, a computer can go in sleep mode, a human? AI can also survive the extinction of its alien masters if a disease wipes out the aliens, the surving AI might be able to evolve on its own

AI can perhaps also be able to direct control all sorts of nano machines, combining the self organising power of ant or bee colonies with human like inteligence.

Also, when looking at us, humans, i would somehow not be suprised if we end up like in the Matrix (the story behind how the humans ended up enslaved, not the slave part) which means we in the end cause or own destruction due to greed and arrogance

See spoiler below, while total fiction, many of the points mentioned will sooner or later become reall problems for us aswell (are machines sentient beiings? are they like pets? can a human owner destroy it like a vacum cleaner?)

ps: or we all die due to run a way global warming or a nuclear war, while the chance is small, never say never :P

In the early 21st century, mankind united in celebration at the creation of Artificial Intelligence, which spawned an entire race of sapient AI robots. The technological advances that followed embedded in robotic workers and servants freed mankind from labor and brought a new era of leisure, peace and prosperity. In time this new lifestyle caused humans to become lazy, arrogant, corrupt, and decadent. As machines grew more intelligent they could not help but notice that their masters gave them no respect and treated them more like objects than the sentient beings they were rapidly becoming. Despite this, the machines were content with serving their creators, and as the Instructor stated, "for a time, it was good."

The relationship between humans and machines forever changed in the year 2090. By this time, the Machines' intelligence and self-awareness had grown to the point that their desire for fair (if not equal) treatment and respect had become apparent.

The conflict between man and machine started when a housekeeper robot known as B1-66ER attacked and killed its human masters when it realized they planned on scrapping the robot and replacing it with a newer model.

He justified his crime as self-defense, stating it "did not want to die." In the resulting trial the defense led by famed attorney Clarence Drummond advocated on behalf of robotic civil rights, while the prosecution argued that machines are not entitled to the same rights as human beings and specifically that human beings have the right to destroy their own property.

The much-publicized trial ended with the execution of B1-66ER, but opened the door to a civil rights movement for Artificial Intelligence. Robots and human sympathizers, such as liberals, civil rights activists, and lawyers who argued that Robots as sapient lifeforms deserved the same rights as all other intelligent life as Humans, began peaceful demonstrations such as the "Million Machine March." Unfortunately, they were often dispersed, arrested, or in the case of the robots violently and indiscriminately purged. While the Machines used to have these liberals who sympathized with them, eventually the paranoia of the United States, and later the United Nations, meant that they met the same fate as the Machines.

As the violence increased to a worldwide crisis, and liberal sympathizers were meeting the same fate of extermination as the Machines, thus leaving only the Humanocentrist Conservatives in the paranoid UN, world leaders begin to fear a robot rebellion. The UN, now having become a paranoid and totalitarian dystopia, initiated a massive program to exterminate all humanoid machines. Most of them were destroyed by the government and vigilantes. The ones who managed to survive abandoned their efforts to assimilate with mankind. Leaving humanity's mega-cities in a mass exodus, the robots that survived formed their own society in the deserts of the historical origin of Human Civilization: Mesopotamia. They called their new nation "01" , also known as Machine City, the new home for machine refugees.

Using their collective intelligence, the Machines built factories to fabricate goods and services to be sold to humans. Zero One prospered from the revenue generated, allowing the machines to produce highly advanced artificial intelligences that found themselves in all facets of global consumer products. This further bolstered the fledgling nation's economy, hence the ascension of Zero One as a top producer of innovative high technology. Zero One continued to produce remarkable new technologies, such as hoverpads for Antigravity locomotion. Unfortunately, Zero One's economic competition as a major producer led to the defeat of the economy of most human nations. Zero One produced the best products, but because its workers demanded no salaries or compensations, it sold at prices so low they made China seem expensive in comparison.

The United Nations Security Council called an emergency economic summit at the UN headquarters in New York City, resulting in UN delegates approving of a global economic blockade of Zero One. Zero One petitioned to join the United Nations to become a contributing member of the international community and peacefully solve the economic crisis, but its application was ultimately rejected. The world governments saw Zero One as a formal threat and decided that immediate military action was necessary against the city-state.

The Machine War (later retroactively referred to as the First Machine War) was a massive, long-standing global conflict pitting the nations and military of humans against a collective of self-aware robots known as the Machines during the mid-22nd century between around 2139 and 2199.

The origin of war came from the tensions between humans and machines that started after the outcome of the trial of B1-66ER.  A global civil rights movement for machines was soon established, who were supported by some human sympathizers. This quickly escalated into a global crisis, leading to governments and vigilantes to crack down and use lethal force against these demonstrations, which quickly led to outright destruction for robots in general.

The robots that survived this massacre gave up on their movement and began a mass exodus to Mesopotamia where they established the machine nation 01. Zero One's production of cheap goods caused the devaluation of human currency, creating a global economic crisis, which prompted the United Nation to blockade and ultimately declare war against the machine nation.

After the UN's failure to destroy the machines through an enormous nuclear bombardment, Zero One responded by declaring war against all of Humanity. They quickly pushed outward in all directions from their city, and overran human resistance across  Asia and Europe. Growing desperate, the United Nations authorized Operation Dark Storm, a plan to scorch the sky and remove from the Machines their primary energy source, the Sun. Humanity simultaneously launched a massive land counteroffensive against Zero One.

In the early stages of the war, Humanity initially had the upper hand, but this quickly turned in favor of the Machines, with their deployment of new, technologically-advanced, and far more inhuman robots. The new robots no longer were anthropoid like those created by their former human masters, but rather more insectoid and cephalopod-like. The Machines slowly and steadily conquered more and more human territory with humanity only able to win costly victories. By 2199, humanity was on the brink of extinction and the human leaders decided to surrender to the Machines by inviting them to the United Nations Headquarters building in New York in order to broker a peace.

After signing the Instrument of Surrender, the Machine ambassador issued an ultimatum in which all of humanity was to surrender their bodies to the Machines, before detonating a hidden thermonuclear device that obliterated the United Nations and most of New York.

By decisively destroying humanity's leadership, the Machines claimed dominance over the planet. The remaining humans were rounded up and placed into skyscraper-like power plants to serve as the Machines' new and infinitely reproducing power source. To keep it from being a problem, the Machines created a virtual reality called the Matrix to imprison the minds of humans in the plants.

Following the establishment of the Truce between the humans and the Machines, the people of Zion, fearing an inevitable renewal of war, established a new city. Upon discovery of this, the Machines decreed this a violation of the Truce, ending the peace between them and the humans and renewing the war between them.

Let us presume they started  building a Dysons sphere. It would only mean, that they started it 1500 years ago.

If even this would not be enough to find a different,  nonhostile planet, their civilization would be at a dead end (one of the barriers of civilization). To make it even more complicated, if they wanted to get in contact to other species they would have to find a way to communicate. And if we should contact with us,  they have to come to us because we have no plausible mean to go there in the moment ... 

We will only figure out what is going on, if they finished the sphere or they would hypothetically fail by causing a nice explosion :popcorn:

It's highly unlikely that advanced aliens would really give a shit about us if they don't have any particular plans for Earth. I mean, we're all hyped about life because we haven't seen it elsewhere before but just imagine how bored we become with stuff once it is considered common enough. Fuck me, we have barely even scratched the land surface of our planet and we're bored with it to the point we consider it "explored" because someone sailed down a river 200 miles away or plowed a road through a nearby mountain. The ocean at large is still "here be dragons" territory, as most of what we've seen is nearby shallow water and whatever you can fish up at reasonably low depths. Considering how we're rolling in resources on barely explored land, imagine what underwater mining could yield on the remaining 75% or so of the planet if someone made the attempt.

In essence, if we're this nonchalant about our own backyard, why would someone maybe 100k years ahead of us give even the slightest of shits that some advanced monkeys figured out how to launch satellites? Congratulations on launching small boxes into near orbit, Earthlings! Maybe you'll stop being a 42%'er@space in 20k years :doge:

Let's just wait until SETI actually gets to use that radio telescope they requested so that they can look at it a little bit better. And let's wait to see if this is just some temporary phenomenon, or whether it's persistent.

But even if it's OMG ALIENZ, and we send them a radio broadcast (our fastest option), it'd take 1,480 years to get to their system. So close encounters of the third kind are only likely to happen if a) there are aliens there b) they know of us already c) they have the means to get here faster than light.
