“Alien life exists elsewhere. The odds are just too good.”

“But alien life visiting us? No. Impossible. It could never happen.”

Are scientists just retarded?.

“No you can’t come here. We’re off limits. No way no how. Cope.”

It’s fucking weird.

Do scientists not consider successor theories to our own limitations? Do they think our limitations are everyone else’s limitations?

People often say ocean worlds can't possibly have technological life because they wouldn't be able to light fires under water. And harnessing of fire was the greatest human technology that enabled most of other human innovations. Which I do agree with the second part. But really, why are people so certain about this?

I can think of how technological life could emerge on ocean worlds. Semi aquatic life that evolves to live on floating debris on the surface of the ocean like icebergs, dense clusters of floating algae or some other material that floats. Like seals, and then they evolve to build floating and semi submerged shelters like beavers. They become intelligent and build submerged cities like giant boats or semi submerged ocean platforms. They'll be able to burn dried out aquatic vegetation for fire, or their own and animal waste. They can develop over shallows and build artificial islands. Eventually they discover fossil fuels and even coal can be mined under oceans and the rest is like human development. All this solves the can't light a fire on an ocean world problem.

there still could be a shit like oil floatin on that ocean world

>>
>>16869517
This all seems really specific and unlikely. We don't have anything remotely like it on Earth, and the closest equivalents all evolved on rocky continents for hundreds of millions of years before adapting to sit on ice or build shelters out of also-terrestrial plant life. They're not frontrunners for intelligence, tool use, communication, or any of the other indicators you might expect a civilization to emerge from.

It also glosses over metallurgy, which is kind of a big deal for technological development. It's not impossible, but building artificial islands and coal mines with bare flippers or sharpened kelp is probably not the greatest path to spaceflight.
>>
>>16869706
Artificial islands come later, but I suppose it could be done early on in their development just by throwing generational bodies at it. What comes early is probably is dense floating platforms like icebergs. Whole towns could be built on large icebergs. Artificial platforms built in shallows could be next, or daming off shallow bays and making an inverse bay with dry land in the middle.

Like how apes evolved with predation the ground to escape to tree tops where they were safer. It could by similar on an ocean world where complex life evolves to be semi aquatic over dense floating debris to escape heavy predation in the water
>>
Anyway, I'm not saying that it is more likely for technological life4 to emerge on ocean worlds. I'm saying that it is possible based off what we know of life on earth. And all the people that claim it is completely impossible are probably wrong.

Of course, on some ocean worlds it may be completely impossible like mot enough oxygen saturating the atmosphere because of oxygen sinks. Those worlds probably exist and Earth used to be one such of these worlds billions of y4ears ago.

And this is without getting into the history of the planet. Maybe the ocean world that's being looked at was an earthllkie world 100 million years ago and intelligent life survived the transition to to an ocean world.

I just don't think ocean worlds should be completely written off as not possibly having technological life. They may even be the second most likely planet type for technological life to emerge based on what we know of earth life. As well, at this point, we also know there are a lot of ocean worlds in the galaxy and they are more common than earthlike worlds.

What would be there to stop intelligent life from learning to harness hydrothermal vents or create exothermic reactions underwater? Or a biotechnological civilization where instead of fire they do weird alien alchemy using enzymes?

If we are in a simulation isn't the obvious direction to pivot to is research into observing extremely high energy particle events and things at the smallest pixels of our reality to try to force memory errors and frame rate stuttering to get hints of the language our reality was engineered in. If we pushed on enough outlier cases in the simulation where it is forced to process extreme computations instead of approximating it we might be able to reverse engineer the source code reality is written in piece by piece.

Programs or software can never access the source code of their hardware because it operates on a different dimension.

People talk about how unhealthy smoking is, but why did nobody talk cigarette tar contaminating the environment and third hand smoking?

I've just had to clean a computer that reeked of a smokers room. The experience nearly drove me insane, especially from the paranoia of that dust and gunk getting kicked up or being deposited on the cleaning equipment and parts of the house.

How does this nearly impossible to remove residue not become a bigger concern? It feels like only one step removed from the likes of asbestos or Chernobyl dust. Not only does it smell rancid, but also is every bit carcinogenic and clogging for your body as it smells.

So why is tobacco tar not a global chemical hazard crisis?

The tar coats the inside of your lungs, protecting them from other harms. The medical establishment doesn't want you to know this because they profit off of you getting sick. People working in asbestos mines didn't have health problems until the government banned smoking in the workplace, which removed the ability of miners to protect their lungs from Asbestos harm by coating them with tar from cigarette smoking.

Yes, women are remorseless egoistic psychopaths and pathological liars by nature, driven only by lust for Chad cock, disgust for beta male and envy for other women. However, there are some noticeable exceptions who are surprisingly honest and altruistic. They're called findoms. Compare the honesty of a purely transactional relationship where the woman openly demands your money to the dishonesty of a wife or gf who causes emotional disturbances because you didn't pay something for her even though she never explicitly said it. Consider the selflessness of a findom who willingly overcomes the deepest female disgust, i.e. interacting with unattractive men, only for a small monetary compensation and by doing so gives meaning and purpose to countless lonely losers, effectively saving them from suicide. Meanwhile a normal woman will just make excuses and ghost you, leaving you to die in bitter isolation. Furthermore, a normal woman will just close her eyes to the fact that beta males are born to be virgin losers for life. She will tell you shallow lies like "there someone out there for everyone", just before ending the conversation and never talking to you again. A findom on the other hand will accept scientific facts from evolution and state them clearly: a beta male exists as a sexless cuckold provider for the females having sex only with alphas. This is how it works in animals and after all, humans are animals, too.

This is the Hercules-Corona Borealis Great Wall, the largest known structure in the universe, a massive galaxy filament stretching about 10 billion light-years across. This breaks the laws of physics as we know it. The Cosmological Principle says no matter where you are in the universe if you look in any direction you should see an even distribution of matter this in turn creates a limit for the sizes of objects. It's about 1.2 billion light years
meaning that this structure is 8 times the supposedly limit of the largest
object possible.
>>
>know it. The Cosmological Principle says no matter where you are in the universe if you look in any direction you should see an even distribution of matter this in turn creates a limit for the sizes of objects. It's about 1.2 billion light years
That is not true. It depends entirely on how you define an object. You could draw a sphere that went around the whole observable universe, and call that a strucutre. Or you could just join up multiple filamnets and call it one big structure. The problem is that when you go above the scale of galaxy clusters, none of these structures are gravitationally bound. So there is no objective definition of what is one object. So the size of objects you find depends entirely on the method and definition you use. The data people use to claim these gigaparsec structures is very sparse (less than 25 galaxies, GRBs). And with any dataset there is noise in the distribution of galaxies just based on the low numbers. Also with so few galaxies you can smear many structures into one. People have shown that the same methods used to find this "wall" also find structures of the same size and significance in totally random simulations. So these "objects" are not statistically significant evidence of a violation of the cosmological principle.

I'm racially (as in descending from the slaves and their masters) african-american, so this topic perturbs me particularly.

I'll often peek into and sometimes speak in "chud" spaces, and one thing I've seen an increasing amount of is the claim that american "blacks" are actually becoming dumber. From what little I've seen, this phenomenon seems to be limited to big cities, and noticing just how fertile the dumbest of "black" women are, I'm willing to bet that the cause is just immigration. I'm still concerned, though, because I also know that our mean iq *seems* to have stopped increasing in the early 2000's after reaching 88: I recall a counter study to a claim that we now had an average of 93 in 2010's?(I actually don't remember where I read it nor when it was published) showing that there was no increase from 88 when age was standardized, so I don't see an actual decline as impossible. Then again, immigration could've also acted to mask any gains that have occurred since then..

Regardless, I'd like your input.

I would expect 2 effects each in opposite directions.
Both stemming from welfare utilization.
Better nutrition is probably responsible for the flynn effect we observed across the board.
The reversal of flynn is probably the obvious dysgenics kicking in (idiocracy).
I would caution trusting modern treatments of the subject of black iq since it is such a third rail issue.
The error is likely in the direction of overstating black iq since liberals wish the gap didn't exist and any lack of improvement is an implicit admission of failure of the liberal efforts to close the gap (of course they are inclined to give themselves a good grade).

>>16869679
The thing most chuds are incapable of understanding is that all these effects played out statistically over very large sets, and that the *actual difference* in IQ between the various subgroups did not vary by much. Indeed, the *rate of difference of IQ between individuals within any given subgroup* still exceeds the average difference in IQ between competing groups. This concept is too complex and difficult for chuds to understand the ramifications of, or why their short term racial-political beliefs are insufficient interpretations of reality.

I believe in the theory of evolution by natural selection but I do not believe in abiogenesis. No matter how many organic compounds into a "soup" you will never get life. Shock it, boil it, blast it with radiation, it's not going to suddenly self-organize. The simplest possible living, self-replicating cell has more divine machinery than any scientific busybody can even observe let alone hypothesize its origin. The idea that only these insanely complex organisms remain while every single intermediary step vanished without a trace and fails to reemerge is absurd.
