xantoxis, w What no one has seen before: new study simulates gravitational waves from failing warp drive

The abstract does a poor job of explaining one of the primary motivations of this research: if Alcubierre drives can exist, and can be built, then it seems likely a sufficiently advanced alien species would have built them. We could therefore find them by detecting the drive failures associated with the hypothetical tech, something which is likely easier than actually building the drives ourselves.

Melatonin,

Won’t it be funny if it turns out WE’RE the most advanced alien species? Like, we’re out here wasting time with SETI and this failed warp drive things, when we should be concentrating on UNIVERSE DOMINATION!!!

xantoxis,

This is an actual proposed solution to the Fermi Paradox. We’re still relatively early on a universal scale. It’s possible we’re just… first. Or so early that hardly anybody else is out there yet. Could be that a billion years later, advanced life is all over the place.

In your formulation, we would also be the explanation for another species’ dark forest hypothesis…

Personally I find this very probable:

First, the big bang happens and stars are made

Then a star large enough to fuse heavier elements needs to live its full life then die of a supernova to create elements heavier than iron

Lastly those remnants need to form a new solar system with a planet somewhat rich in these heavier elements to support life, as well as the time needed to have life spring up in the first place

In terms of how long all of these take, we’re pretty young cosmically

Spzi,

While possible, it goes against the Mediocrity principle:

The idea is to assume mediocrity, rather than starting with the assumption that a phenomenon is special, privileged, exceptional, or even superior.[2][3]

p03locke, w Japan’s moon landing picture might be the space photo of the decade
@p03locke@lemmy.dbzer0.com avatar

It’s such a harsh message to propagate, though. A lot of these smaller countries have been really pushing their space programs, and they don’t need “LOL, lander upside-down” memes to accent their recent failure any further.

At this rate, Japan may be able to actually land on the moon in a few more years, take some great pictures, and shove Mashable’s “space photo of the decade” quote directly up their ass. Where it belongs.

Yep, totally agree

I clicked on this post hoping to see something cool. Didn’t realise they were being pricks.

Getting shit into space is impressive, full stop. Ridiculing failure on the frontier is just sad.

ringwraithfish,

I’ve been binging on For All Mankind and it’s been a great reminder of how difficult space exploration actually is and how quickly things can go wrong.

The fact that they accomplished their goal of pinpoint landing within 10 meters of their target should be the lede.

I bet people in the industry are amazed by this accomplishment.

dustyData,

It’s the sad part of science communication. The pop culture sees difficulties and failures as indictments of character. In science, failures are the fuel of progress. In this case, especially in scientific circles, this was a massive success and is being celebrated as such. The upside down part is laughed at as just the price of making the unimaginable, possible. But most publications who don’t belong to science journalism just don’t understand.

SaiPenguin,

Why would that lead to shoving a quote anywhere? Much of the marvel of this photo is the unusual circumstances around it.

We’ve already got photos of the moon.

This, afaik, is the first photo we have a lander that suffered a significant complication in the landing but was still able to deploy a rover to take a picture.

JoMomma,

12k miles is very close, the headline is using ridiculous comparisons, but 12k is closer than many medium and high orbit satellites.

Which on the scale of the solar system is essentially the width of a damned hair. We have satellites in higher orbits than that.

jam12705,

I’m not up to date on the latest elephant measuring units but we’re talking at lease 7.8million horse lengths away of that helps.

If you’re looking for greater accuracy we can always convert that to badgers with a simple formula.

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

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

TommySoda, w Starlink is increasingly interfering with astronomy, scientists say

As someone that uses Starlink due to nothing else being in my area, I hate everything about this. Sure the convenience of having internet wherever I want is nice, but this still sucks. Especially since I’m a huge space nerd so this shit just hurts my soul.

AlexWIWA,

In your defense, there should be internet in your area but the government dropped the ball and let Comcast scam them.

TommySoda,

My favorite part is that bout 5 miles down the highway they have fibre optic. They’ve been “installing” it for about 4 or 5 years now. They’ve had the spool just sitting outside for half that time.

AlexWIWA,

God that’s just depressing

14th_cylon,

5 miles is doable with a wirless link. it of course depends on other factors, like having visibility, but it is not impossible.

naeap, w OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)
@naeap@sopuli.xyz avatar

What is it with the blue/violet/red-yellow stuff?

Is this some metallic thing?

fossilesque, (edited )
@fossilesque@mander.xyz avatar

Knowing what I know, I am assuming this image was standardised and then normalised (fancy stats algos to keep things in the same visual range) while stitching it together, and the final product enhanced a lot of colouration (saturation). They’re subtle or undetectable to the naked eye, but they exist. They are reflected in the different minerals present. I’ve done this stuff (raster stitching) with different imagery. Op was active in the comments with info, but I didn’t read up on it.

foofiepie,

Pasted from the Reddit thread:

The colors don’t match what a human eye would see, but without going into a philosophy tangent, color is extremely complex and a huge part of what a human sees is your brain doing representations and mapping that isn’t perfectly represented in the physical object being observed. In this photo the saturation has been increased (versus a human eye) because it helps show the geological differences on the lunar surface. The reddish areas are high in iron and feldspar, and the blue-tinted zones have higher titanium content. Instead of thinking of the color as “real” or “fake” it’s probably better to think of it as a tool, to simulate if you were a super human with the ability to adjust saturation and detect metal composition with your eye. Usually when a photo like this is shared by researchers and scientist all this nuance and exposition is included, but then journalist and social media get a hold of it and people start crying “fake” without an understanding of what the image is trying to accomplish. TL;DR - The image isn’t what a human eye would see but it isn’t just art to look cool, the color and modifications have physical meaning and serve a purpose.

fossilesque,
@fossilesque@mander.xyz avatar

Those are great explanations!

Liz,

Yeah when you get into “proper” photography you quickly realize a “real” image is somewhat subjective. This moon is cracked to 1000%, though.

fossilesque,
@fossilesque@mander.xyz avatar

It’s true. I did photography as a hobby as a kid and it set me ahead when I started mapping. It’s all the same no matter the domain.

StaySquared,

Excellent explanation. Appreciate you sharing it!
