Perhaps we're just not as interesting as we think. Maybe aliens don't want to contact us for the same reason I don't want to contact kids playing in the park: I'm simply uninterested in whatever they're doing.

Lol makes me imagine that the alien species have a law against approaching humans or be charged with pedophilia.

[–] [email protected] 43 points 5 months ago (1 children)

Nah, they just have a bunch of myths about the evil homo sapiens abducting their alien babies.

It is homo phobia.

It's also likely that an alien species capable of interstellar travel doesn't want anything we have. Our resources aren't anything special, they have no need for slave labor and we don't produce anything of interest to them. It's a long drive. Why burn the gas and waste the time?

[–] [email protected] 3 points 5 months ago (2 children)

Knowledge.

Why are there scientists here on Earth studying the most boring subjects imaginable to anyone but them? Why does every tiny organism have a small, but dedicated group of scientists studying it at some point?

We must know - we will know! is a quote which represents humanity well. A factually wrong quote since we will not know everything but, an objective nonetheless. Why should other species believe different?

Time.

Timeline wise, we could be at the beginning of when other species are becoming sentient. Or we could have missed them by a billion years. The gap to get in contact is so massive that the odds are stacked against it ever happening.

[–] [email protected] 25 points 5 months ago (1 children)

Distance and time. No one seems to have a clue how far a light year is ... I mean maybe ur finding someone in ur own galaxy over a big enough timeline but sorry 2000 light years to the nearest galaxy? Not a chance.

[–] [email protected] 10 points 5 months ago* (last edited 5 months ago)

Yep, relativity is a bitch. Even if we could do the speed of light, our time here would pass so quickly that by the time we reached some place that had life, ours might have stopped existing.

And yes, I know a light year is not a measure of time, but distance, but it still takes time.

[–] [email protected] 6 points 5 months ago

I think this is part of it. If the speed of light is the speed limit of matter, it would be very difficult to travel anywhere within reasonable amount of time considering norminal life spans of even the longest living things on Earth.

[–] [email protected] 5 points 5 months ago

This is the answer,

100 different civilizations could have happened in our galaxy in the last 1 million years with only a few centuries of them emitting detectable signals.

And it could be worse, it could be 10 civilizations in the last 1 billion years.

Blipblop: β€œThose creatures on that planet are perplexing. Constantly at war, decimating their natural resources, consuming everything in their paths. Like a cancer overtaking an organism. Should we contact them?”

I'd seen this before, but was happy to reread it for gems like this:

"You know how when you slap or flap meat it makes a noise? They talk by flapping their meat at each other. They can even sing by squirting air through their meat."

Such a beautiful description of the human voice.

I like how you assume another civilization would be any more rational.

Why the clickbait? Just put why in the title

[–] [email protected] 4 points 5 months ago (3 children)

It's the title of the article. Should the OP just put whatever they want for a title?

[–] [email protected] 14 points 5 months ago

Yes, appended in square brackets, to indicate that it is not part of the original text.

[–] [email protected] 11 points 5 months ago

This is a service I would appreciate. Or at least put it in the description.

[–] [email protected] 3 points 5 months ago

Yes, modern article titles are designed to get you to click it so they make money off advertising to you

So if they are right, the Earth is incredibly rare and would be a great find for space faring civilizations. They also had plenty of time to pass by and find this incredibly rare life bearing sphere. But they didn't. You can flip things how ever you want, the question remains - why haven't we seen anyone?

[–] [email protected] 20 points 5 months ago (6 children)

It's simple. We're the first intelligent life in the galaxy. There is nobody else yet in our galaxy.

Also, probably nobody capable of traveling the stars wants to settle a planet. Once you figure out how to make huge spaceships (which you'll need to travel interstellar space) you've essentially learned how to make cities in space. Our solar system would support a lot of people if we just used the resources available for space habitats, and by "lot" I mean in the quadrillions. And it turns out that all you need to support that population is a star to provide energy, and some planets to source materials from.

So with that in mind, why bother finding another habitable planet?

[–] [email protected] 3 points 5 months ago

The thing is, out of a population of trillions (or even quadrillions as you say), you only need a few thousand to travel to the stars to colonize another planet. With how large the population is, that is bound to happen. Just like there were bound to be pioneers travelling to the new world to settle it, despite how dangerous the journey was. And how there will be pioneers to settle the moon or mars or further out.

And a civilization like that would absolutely send stuff to other star systems, if only for science, so most of the research for the journey would already be done. And this is assuming that a civilization wouldn't want ever greater quantities of resources for ever greater projects, or access to other star systems for reasons we cannot fathom today (maybe neutron stars or black holes have some incredibly tempting uses? Or maybe there's some useful resources out in the galaxy that we have yet to discover?)

Basically, a successful civilization like that is bound to spread out, it's difficult to see scenarios where a successful civilization would be so homogenous in thought as for that to not happen. Amd then it's before we even get to sending AI probes to "colonize" space and gather data.

They actually haven't had much time to pass by. Earths only been around for 4.6 billion years, a couple hundred million of that was spent being a cooling ball of magma. Space is fucking huge and the universe is still very young. It's very likely we are on the early end of the development of life in the universe. A lot of things had to happen before our complex life could evolve.

[–] [email protected] 8 points 5 months ago (7 children)

As you said, after the formation of Earth, it took only a few hundred milion years for life to develop. That is incredibly short, almost instanteneously as soon as conditions for life were met, life formed. Our galaxy, the Milky Way, formed almost as soon as galaxies could form. So here we have a situation where a inteligent civilization could have formed anywhere in our galaxy 13 bil years ago or at any point in time after that. Chance is, if they had, by now they would have conquered the whole galaxy. Absence of any sign of inteligent life can be wxplained by the Great Filter. It could be any of the following: 1) interstellar travel is never feasible for any civ, no matter how advanced, 2) Earth-like planets are so rare, that we are probably the only inteligent civ in our galaxy, 3) Earth-like planets are not that rare, but inteligent civs tend to destroy themselves before they manage to spread out to other planets... We don't know what the Great Filter is, but it must be pretty destructive for a civ. I just want to point out the fact that the Great Filter is probably still ahead of us and that we shouldn't take our existence for granted. We need to meticulously examine and neutralize any possible threats to human civilization. This is not fearmongering. It's just common sense, after you take all the facts into account that I laid out.

[–] [email protected] 5 points 5 months ago (1 children)

Actually life needs complex elements that only form in neutron star collisions(kilonovas) It could have been that the universe needed to be a couple billion years old before the elements that could create complex life actually came into existence. Everything else is pretty accurate, and I do think interstellar travel will end up being impossible, even terraforming other planets seems like it's a couple thousand years away.

As far as earth-like planets being rare, even if they are only 1 in 10,000 there would likely still be tens of millions in our galaxy alone.

[–] [email protected] 3 points 5 months ago

I think 1 in 10k is way too common still. Somewhere between 1 in a billion to one in a trillion is more reasonable.

Maybe it's impossible to travel faster than the speed of light? So it may not be a thing where aliens can just swing by our solar system to snap a few photos before heading off to the next one.

Maybe it's because we're not as evolved as we think. If aliens did appear, how many kooks would want to attack them because they are different?

If they land in one country, would other countries get jealous or scared, thinking that country now has an advantage? Shit, what happens if the neighbouring country had nukes; would they launch?

More likely is that if aliens had detected life here, Earth would be marked as a red, no-go zone, because of how unstable, tribal and violent we are.

[–] [email protected] 4 points 5 months ago

Every conservative on earth would demand we attack the flying illegal aliens. Our planet's dumbest of dipshit right-wingers would be outside shooting at clouds all night long.

[–] [email protected] 22 points 5 months ago (4 children)

There are many ideas and no definite proof. I like the idea that species either try to reach the stars and fail because it costs too much energy, or they find a sustainable lifestyle and not leave their home planet as Dr. Fatima pointed out in a good video

[–] [email protected] 3 points 5 months ago

Dr. Fatima is incredible, absolutely love her.

What, it wasn't enough to just gesture meaningfully at the state of the entire godamn planet when looking for reasons why aliens might want to avoid us?

[–] [email protected] 20 points 5 months ago (4 children)

I was going to say this. To those species who are capable of interplanetary colonization, we look like savage war goblins who can only negotiate transaction-based societies and are compelled by number-go-uo at the expense of letting children starve.

[–] [email protected] 3 points 5 months ago (1 children)

Couldn't the aliens be the same way?

It can be as low as only four out of 10,000 galaxies having one civilization

Well that's a new depth of loneliness I didn't know existed before. Great.

[–] [email protected] 3 points 5 months ago

I like to think about it differently: That this planet is an incredibly unique and rare thing and humans are even more incredibly unique in the universe. And from that one thing makes us and our planet very very special.

Rare Earth by Peter Ward is what you're after here. I took an elective in college that effectively was reading a bunch of space science (and history, it was odd) and discussing. This one caught me off guard but was a decent breakdown of a possible answer to Fermi.

I don't necessarily agree with the supposition, mainly because it still comes from a place of specifically carbon-based life as the end goal. But they do lay out reasoning in an easy to understand way that was super neat to learn.

[–] [email protected] 9 points 5 months ago

"It's like winning the lottery," Taras Gerya, a geophysicist at the research university ETH Zurich in Switzerland and an author of the study, told Mashable. "It can be so rare that we don't have much of a chance to be contacted," added Gerya, who coauthored the study with Robert Stern, a geoscientist at the University of Texas at Dallas. -article

I liked the Jupiter rising explanation. Just a planet free range farming for organic matter. Would make alot of sense.

[–] [email protected] 5 points 5 months ago (2 children)

Why would they contact us? Kopernik got a lot wrong, but he was right in that we are nothing special. A species advanced enough to contact other lifeforms must run across planets in various states of ruin 12 a day.

Even on the remoteest of chances that there is it a sapient life form capable and technologically advanced enough to contact us in this galaxy cluster, much less nearby?

Why the hell would they? We are obviously fucking crazy.
