WHY have we not seen aliens?

[Anonymous No.11548862]

because they're not there

[Anonymous No.11548868]

We haven't even gotten started yet.

>Our sensory faculties have limitations, even with specialized equipment that has afforded us significant breakthroughs in recording and understanding the immediate universe, it's not unlikely we biologically and mechanically lack the ability to perceive other "intelligent" life and perhaps vice versa.
>We don't really have a very good reference point for what qualifies as intelligent life anyhow. The qualities we consider intelligent may have no bearing on extraterrestrials.
>The processes and occurrences needed for Carbon-based life to sustain itself (let alone emerge) are very complicated and require a great deal of fortune.
>The timespan in which aforementioned processes and occurrences take place ranges across billions of years. A timespan in which other life-ending scenarios and complications may also occur - compounding the unlikelihood two species on two planets will (roughly) simultaneously emerge, evolve, develop a degree of sentience, and interact with one another.

Speak for yourself. I, and a good handful of other people, have seen multiple aliens. It's just that you're not competent enough to contact them yourself.

That's literally what theists say about god and god would explain a whole lot more than aliens but there's still absolutely zero evidence for god either.

Because THE VAST majority of life is found on planets orbiting within the plasma sheaths of their parent brown dwarf stars. Earth, we, we are a space oddity, life existing on a planet the way it does here, around a "main sequence" star is exceedingly rare and demands a very unique set of events to occur before it can become a reality.

If you travelled to hundreds of thousands or even millions of "main sequence" stars similar to our Sun, and checked the orbiting planets for life, you'd most likely not find any. And if you went and checked out a lots of brown dwarf stars, you wouldn't be able to see any life either, because you wouldn't be able to see through the thick intensely glowing plasma sheaths. Nor would your radio waves or other scanning methods be useful. Most likely your ship wouldn't be able to penetrate through the sheath either without getting fucked up.

To put it simply, the reason we don't see aliens is because they're out of sight from us. And we're out of sight from them. Everyone's hiding from each other, iwithin their own little cosmic wombs like chickens inside eggs. We could find aliens who are in the same situation as us; being on a planet orbiting a "main sequence star", but due to life existing under such an arrangement requiring an very specific chain of events to occur first, it makes it extremely unlikely for the inhabitants of two such planets to ever detect each other.


To help you understand further, more in-depth, as to why we haven't detected any aliens and why they (most likely) haven't detected us, see (note the timestamps):

The absence of evidence is not evidence of absence.

WHY are we seeing this thread over and over?

Seriously, this board is no longer science and maths, it's popular science and debating trivial bullshit that is impossible to prove

Pretty much this. Or in case if they do exist, it wouldn't matter anyway due to how far away they are. It's a pointless debate

statistical evidence is plenty for both.

stop posting this retarded post in every fermi paradox thread. The evidence of absence is all the concrete evidence we have that the universe appears to be in pristine, natural condition.

>>11548858
interstellar distances are too vast for travel and a high percentage of intelligent life has yet to reach the level of technological sophistication for radio

There really is no Ferma "paradox". Life is very rare, and sentient life probably more so. We may be the only ones, or we may be one of "few" (e.g. it could be 5 sentient species per galaxy or 1 sentient species per 5000 galaxies, which still means like millions of sentient species). The first option is less likely but means we have lots of scientific areas to explore. The second option kind of sucks, since in that case - where are the von neumann probes, where are the detectable signals using advanced technology from automated spaceships that can be read a galaxy away? If sentient species with millions of years of science behind them can't make a self replicating probe to send their message ad infinitum, then we can't either. That, or life is extremely rare to the point that we can never actually reach each other due to the nature of an expanding universe.

But yeah, we will probably never see aliens if we haven't seen them by now.

[Anonymous No.11550633]

Oops, swap first and second options

[Anonymous No.11550634]

Because they don't exist in the way we expect them to exist.

Rare Earth and Rare Multicellular Life. If it existed, we would have seen it by now as it would take up whole chunks of the night sky.

I think it's unlikely that there are any technologically advanced civilizations in our galaxy or in any nearby galaxies. But if we are talking about the entire observable universe, it has fucking ~2 trillion galaxies, I think it's a bit early to say. Especially since SETI has never received much funding and a lot of it has focused on searching for radio signals which I think has a low chance of succeeding - looking for technosignatures is the way to go I think since that's expected to be visible even if they aren't trying to catch our attention specifically.

Because we've only been looking for like 100 years

[Anonymous No.11551179]

>>11548858
first confirmation of an exoplanet happened in 1988
first confirmation of a planet orbiting an ordinary star happened in 1995
first spectroscopy of reflected light from a planet happened in 2015
in total there have been only around 2000 exo-planets studied thus far, most were merely observed and not put through an in-depth study

it is not statistically likely that we would find life on such a small sample

[Anonymous No.11551190]

We probably wouldn't find an alien civilization just looking for radio signals. They'd be so diluted by the time they got to use from any serious distance they'd be indistinguishable from background radiation. The only way we're ever going to know if aliens exist is if we catch them building a Dyson Swarm or lighting a really big fucking engine of some kind for some reason, or by pure fucking chance a colony ship or probe of their's visits our solar system.

>we not seen alien
I saw a canadian once, at least I think it was. It was talking real funny like.

[Anonymous No.11551203]

One thing to keep in mind is that the universe, in the condition it is in right now anyways, is likely very young. It's entirely possible that humanity is one of the first intelligent species to arise, even if just in our local cluster.
