Paragone, w After all of This Time Searching for Aliens, is it The Zoo Hypothesis or Nothing?

The commenter who identified that we’re now able to eliminate radiowave-broadcast communications, via lasers ( & fiberoptics, etc ), is spot-on.


There is another angle, though.

Imagine a simplified-model of civilization…

a batch of 7 newborn-babies, instead of hundreds of genetically-distinct populations in Africa…

those 7 babies live in “eden”.

they learn that they can consume everything they want, that doesn’t harm them.

they learn that they have to be somewhat self-moderating, because others fight them when one crowds the other, too much.

etc.

they move away from each-other, & some lose their skin-pigment, others change it…

an empire forms, in-which industry is the rule ( the Roman empire ).

Now a momentum is set in-place, that is making the sequence of the Industrial-Revolutions inevitable…

at the time of the Roman Empire, the children are, say, 11yo.

at the time of the Industrial Revolutions, they are in puberty, their brains forced into chaos, & ALL sorts of new force-multiplying technologies landing in their hands…

So, what is The Great Filter?

What happens when it is unconscious-toddler-mind, or unconscious-adolescent-who-never-got-challenged, who has all the world-snuffing technologies that we now have, but who has the global-responsiblity-level of … drunk & drugged narcissistic children…

Say you have 7 kids going into The Great Filter, representing the whole populations-sea of our world…

Say only 1 of them survives The Great Filter…

Are they going to be CAREFUL in what they do, technologically, from then on??

Obviously.


I don’t expect more than about 1.5% of this planet’s population to survive this century’s TANTRUM/POGROM that has narcissism-roots, politics-roots, religion-roots, food-insecurity-roots ( like total collapse of the terrestrial & marine food-webs, later this century ), etc.

Will the remnant who survive this century, if any do, be as careless with technology as we currently are??

How could they be?


If The Great Filter is an automatic force-growing-up consequence of EVERY world-overwhelming-species, who mixes accommodated-immaturity with ecosphere-destroying technology, then whatever portion of worlds who reach The Great Filter have survivors of it, … it’d be inherent in the survivors’ experience that they have been made careful.

Same as you don’t find incapable-of-self-discipline in career-military-officers, you don’t find our murderous carelessness/ideological-rabies in any survivor of The Great Filter:

Universe automatically force-extinguishes populations who won’t grow up, who gain the technological-leverage that we’ve gained.


So, silence depicts a lack-of-carelessness AND an absence-of-need to be throwing-away-energy through radiowave broadcast, both.

When combined, galactic silence makes much fundamental sense.

We’re in our species’ “puberty” stage, and haven’t survived our force-growing-up Great Filter, yet.

If we do, well, then finding others who also did, will make sense.

If we won’t, … then our epitaph will be that we wouldn’t grow-up, at ANY cost.

Doubt, something unknown? Sure. Structure? Doubt.

FishLake,

“Structure” in this case means “big glob of galaxies slightly closer together than other globs”

@halcyoncmdr@lemmy.world avatar

In astronomical terms structure doesn’t mean a building of any kind.

derphurr, w Discovery of second ultra-large structure in distant space further challenges our understanding of the universe

It’s not a “new” discovery or even the “second”. I suggest they read the 2015 paper they are almost copying from.

2015 dx.doi.org/10.1093/mnras/stv1421

Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.

Weird reporting like this is “new” GRB ring out of Swift and Sloan SDSS data.

Sloan Great Wall, which is around 1.5 billion light-years in length

South Pole Wall, which stretches 1.4 billion light-years across.

Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide

2015 en.m.wikipedia.org/wiki/Giant_GRB_Ring

It is approximately 9.1 billion light years from Earth and about 5.6 billion light years across

New objects:

Big Ring in the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years

Giant Arc in the Sky which is 3.3 billion light-years across,

I could’ve done it in like 10mins. Easy-peasy. Oxy-acetylene torch, fastener can’t be stuck if it’s a liquid.

It is being stored and a clean room that is temp controlled any heat or anything would contaminate the sample.

Thanks poindexter. It was a joke.

You’re welcome dickhead, it wasn’t funny.

Also I snickered so it wasn't completely lost.

Peppycito,

Having a good day is easy when you’re not an asshole. You should experiment with that concept sometime.

Says the guy being an asshole

GBU_28,

The fuck is wrong with you

Freewheel,

Given that you aren’t the only audience to a response, even someone who recognizes that it’s a joke might add a little bit of context about, I don’t know, how melting the fastener might contaminate the sample or grinding the fasteners might cause dust and sparks that could also contaminate the sample, so on and so forth.

That all being said, are you okay? Kneejerk responses like that don’t usually come from good places.

Maalus,

A sentence needs to be funny to be a joke. Also, not everything needs a joke as a response.

essteeyou,

I think it was fairly clearly a joke, and at least a little bit funny via absurdity, like suggesting nuking it to open it, or wrapping an elastic band around like a tight jar lid.

Not everything you read is serious unless otherwise stated.

GBU_28,

I guess my other reply was too honest for the moderator, but they are cool with your rudeness?

Why are you being so rude?

faintwhenfree,

Funny, not sure why people can’t understand it’s a joke. But I’ve learned my lesson that I always add /S when I do the sarc joke

Anticorp,

I feel like this has definitely been touched up.

mozz,
@mozz@mbin.grits.dev avatar

I highly doubt NASA is in the business of doing that (and FWIW Snopes agrees with me).

Anticorp,

Read the comment right above yours:

lemm.ee/comment/8535233

mozz,
@mozz@mbin.grits.dev avatar

There's a big difference between "touched up" as in, fix the contrast and adjust the color balance, versus "touched up" as in let's make a nebula look like a bat. The first, me and Ricky are in agreement that they're doing. The second, me and Snopes feel strongly that they're not doing.

rickyrigatoni,

NASA always touches up their photographs to add color and contrast or else space would look very boring.

No idea but the moon is always colonized from a profit perspective so far. Haven’t heard anyone interested in leaving it alone.

Haha, not my title, the article’s. I don’t change them too often because it disrupts my flow going through my RSS feeds while I select things I want to get into in depth myself, and I know publishers make these decisions for a reason. The text is pretty ok though. Feel free to downvote them.
