Fermi Paradox

[Anonymous No.12139067]

The discovery of life on Venus has shown us how widespread life is in the universe.
So, why haven't we found any signs of intelligent extraterrestrial life yet?
Is there really a big filter that exterminates intelligent life before it can spread to space?

[Anonymous No.12139088]

Basic life is most likely highly common.
Intelligent life is not. It took earth billions of years to get to Humans, and the universe is only 7 something billion years old. So if we assume that it takes roughly that amount of time for a planet to be created and then create intelligent life, it could be possible that Humans are one of the earlier examples of intelligent life in the universe that is capable of communication. There are probably others, but they are too far away from us for it to matter. There may be dozens, or hundreds, or thousands of planets that are on course to producing intelligent life, but they just aren't quite there yet.

All life desires to stay alive.
There is no way to know if other lifeforms can or will destroy you if given a chance.
Lacking assurances, the safest option for any species is to annihilate other life forms before they have a chance to do the same.

Even if it takes billions of years to advance to intelligence, the next step, going out into space, only takes a few thousand years. According to our own experience.
Even if FTL is more complicated than we think now, generation ships and automated probes could reach most of the galxy within a few million years with just a fraction of the speed of light.

>We have nothing to support this.
well duh. We have nothing to support nor deny it. It's pure speculation. I'm just saying what makes sense to me. The way I see it it seems highly unlikely with just how large the universe is, and how much time has passed since the genesis, that the general timeline of evolution from basic lifeform to human-like intelligence what coincide within the same timeframe.
However it would seem pretty reasonable to assume that every planet that produces intelligent life would follow a relatively similar timeline to earth.
>>12139140
>But humanity only needed about 20k years to go from living in caves to having nuclear technology and rockets.
sure, but the earth is 4.5 billion years old (and also idk why I said the universe is 7 billion years old here >>12139088). The universe being 14* billion years oldish means there has to be the timeframe of the whole universe developing, to planets developing, to a planet situating to a point where bacteria can settle, and then that bacteria takes billions of years to evolve, which also only happens under specific circumstances (see how it would be very difficult for life to progress on Venus if it exists). Even if intelligent life gets into space relatively quickly, getting to intelligent life is the hard part, and it likely takes a long time.
But again, speculation, maybe Earth really sucks and life evolves much quicker on better planets.

the problem isn't evolving human-like intelligence, hypothetically we aren't even the smartest animal on earth once you take orcas into account, the problem is achieving human-level capabilities. what separates humans from birds, whales, and other highly intelligent animals is that we hit a proverbial goldilocks zone of features; intelligence, hands for manipulation the environment, highly social groups that favor cooperation, the development of language allowing the sharing of concepts, alongside some I'm sure I don't know of. hitting this specific set of traits is what caused humans to balloon from generic apes to intellectual powerhouses in a blink of an eye, and while we likely aren't the best at any one of our traits, no other animal on earth has all of those traits at the same time

Isn’t any sort of life (including bacteria-like life) estimated to occur in only one in a billion planets? An even smaller proportion of planets would have intelligent life.

How many planets have we discovered? I’m sure it’s a lot less than one billion. And it’s not like we’ve been able to look in detail at all the planets we’ve discovered to see if they have microscopic life.

Anyway, I’m sure there’s life, including intelligent life, somewhere out there. However, I think extraterrestrial life is really, really, far away, and we are extremely unlikely to ever actually find aliens. The universe is a vast place.

>fermi paradox

not a paradox since it's just SURVIVORSHIP BIAS.
if a galactic civilization exists, then no other civilization will arise independently in that galaxy since all the good planets would be being used already.

it's not surprising for an arisen civilization to find itself in an unreachable area of the cosmos.

>life on venus means intelligent life is common

our solar system isn't a typical one!
just because a life bearing solar system has two abiogenesis events does not say anything about how common life-bearing solar systems are!

in fact, there are models that say there was only ever one abiogenesis event, and it happened on Mars since it cooled down quicker.
then, life was launched through meteor impacts to seed Earth and then Venus.

also,
basic life isn't anything near intelligent life.
it took a billion years to go from the first life to humans.
and intelligent life isn't technological civilization.
it took a million years to go from the first humans to techciv.

if you went back in time half a million years, and changed something, humans would have just died off or stayed as monkeys.

moreover, look at how little habitability is left on Earth: 100 million years. we almost didn't fucking make it!

there are just way too many rare coincidences that had to occur for us to arise to our status today. no way this is happening ever again in this observable universe.

in fact, we can use Anthropic Reasoning to infer that We're Alone:
we are typical observers
the universe still has a trillion years of time left to give birth to a civilization similar to ours
if our type of civ was common, then we would expect to arise somewhere later on in the evolution of the universe where there would had been more time for civilizations to arise
but we are relatively early so this provides us with a rough "MINIMAL TEMPORAL DISTANCE" from other hypothetical civilizations.

we can use the fact about our rarity in time to infer the fact about our rarity in space.

The way for it to make sense would be for life itself to be the great filter. Having multiple signs of life in our solar system doesn't mean much when they can all have the same origin point

>it only takes 4 billion years for life to evolve to be intelligent
That 4 billion years is 95% of the Earth's habitability. In 500 milliom years, the Sun will heat up and kill all life on Earth. We almost didn't fucking make it.

And a planet even getting 4 billion years of habitability is EXTREMELY rare.

>life appeared quick, in less than 600 million years

You're falling victim to survivorship bias.
If abiogenesis didn't occur that quickly, then there wouldn't have been enough time for life to evolve into intelligent life and we wouldn't be here to talk about how Late abiogenesis occured.

Intelligent life shouldn't be surprised that abiogenesis occurred very quickly on its planet.

>Earth is normal

No. Look up the Rare Earth Hypothesis.

>intelligence is an advantage

No. A species is only as intelligent as its environment requires it to be. Dolphins/Orcas are the smartest non-human species because their environment and history is very complex. But species that just live in a static environment actually degenerate in intelligence over time because intelligence costs energy, development time, and carries risks.

For ex: ethnicities that have lived in static environments (tropical jungles) tend to be dumber than ethnicities that have lived in harsh ever-changing environments (winters).

>>12144617
Actually, even if A solar system has multiple cases of abiogenesis, that in no way says anything about how common fecund solar systems are in the universe.

But yes, life most likely started on Mars because it cooled first, then later on was launched to the then-now-cooled Earth and Venus.

The great filters are definitely pre-tech civilzation. For ex: if there was an alien civilization already in the Milky Way, then they would have already colonized Earth before we evolved and prevented us from evolving.

An intelligent species shouldn't be surprised to find itself in a quiet area of the cosmos.

All it takes to evolve intelligence is to have some use for it. It is very well possible that intelligence evolves any time the body plan can use it to some advantage in the given environment. As long as you have ANY kind of brain, it can just grow more massive.

[Anonymous No.12145012]

>>12144994
that's not how evolution works
a species just having a use for something is not enough
for it to evolve that useful thing, you need a selection pressure AGAINST the ABSENCE of that thing.

for ex, the crocodile would definitely benefit from having a triple digit IQ, but it will never evolve to that point because the bottom tier of crocodiles aren't being selected out of the gene pool

that's why the concept of an Idiocracy is a thing: the dumbest humans aren't being selected out of the gene pool anymore.

[Anonymous No.12145237]

>>12145012
If it doesn't make the crocodile better off it isn't beneficial. You are trying to redefine words to mean something ridiculous just to contradict me. If it was beneficial, the crocodiles without it would be worse off and they are not.

It probably wouldn't even take that long. Just travel five light years to the nearest star andthere's no habitable worlds, just build some O'Neill cylinders and move onto the next system. Once humanity reaches around K1.5, it would probably only take one or two hundred years to have a presence in every system within about 30ly

All this talk reminds me of 80's sci-fi movies like Blade Runner where we had space ships and colonies by 2020.

It's not happening. Technology won't progress the way we want it to. In 50 years we will be stuck playing VR all day on UBI. We will be lucky to ever get that Mars city going at all.

[Anonymous No.12146887]

We have a responsibility to destroy all alien life. We cannot allow god knows how many planets to harbor life unchecked until it evolves to the point where it could be a threat. Look how fast humans went from the invention of the radio to the invention of guided ballistic weaponry and atomic bombs. And it's not fair to assume that another species might be able to make these advancements even faster. We could ignore Venus for a few decades and before we know it there will be a swarm of interplanetary atomic missiles striking our home.

[Humans are savage. No.12147201]

The biggest obstacle to life is going from nothing to life. Then it's going from single called organism to multi celled organism. If you get passed that then you need just the right environment to produce intelligent life. Those are the 3 almost impossible stages for intelligent life to exist. Humans are having a hard time transitioning to a co2 neutral economy we may not get passed that stage. Plus, our lifetimes are limited. If we could extend life to hundreds of years you would see a massive increase in our capability but that would put a lot of pressure on our planet.

We're one of the oldest planets in one of the oldest galaxies. On a human timeline we've been around for 3 seconds and we're asking where our brothers and sisters are.

And not only how long did it take our planet to even develop favorable conditions for basic life, but what an interesting path it took to develop sentient life. How many mass extinction events did we go through? Too many for comfort.

Out of those trillions and trillions of years of the whole lifetime of the universe only a fraction of that actually has the conditions to sustain life. The universe is young but the proportion isn't as extreme as you think it is

I'm talking about EARTH LIKE planets.

If we found another Earth in the Milky Way, we would go colonize it and change its evolutionary trajectory. Even if it would have evolved intelligent life and technological civilization if it was left alone to its own development, we wouldn't allow it to continue like that.

The same thing would have happened to our Earth if there was a galactic civilization nearby. Thus, the Survivorship Bias.

Thus, a technological civilization shouldn't be surprised to find its home planet to be hidden away in a lonely area of the cosmos.

>big filter that exterminates intelligent life before
No, but what's actually happening is far more terrifying.

The universe is alive and able to react. As in: It can respond to the collective sapient will of entire planetary civilizations. For humans, since there are those of us who are willing to use dark forest tactics against other worlds, our entire world is being punished using those same tactics. We are stuck in a loop of our own malice not in a universe that doesn't care—but in one that does.

This implies that there are countless civilizations out there among the stars, ones that could easily uplift us, advance our science and knowledge, give us the tools and technologies to bring about our best future, but they won't be able to until we allow it. We're obviously not rotten to the core, but the universe doesn't care. It's not going to take chances with violent races. There's literally nothing stopping it from waiting for literal evolutionary time periods for us to become less violent or else get replaced by a more understanding species.

Call it evil, call it cruel, it's irrelevant. The universe found a way to foster life among the stars and it took it. War is simply not compatible with Kardashev type energy use.
