What the fuck is “half a pickup truck” for a measure
Two of them is roughly the size of a pickup truck…
Like, it’s volume, they could say X gallons, but it would be hard for people to visualize. So people use an example most readers would be familiar with.
Have you honestly never wondered why journalists use random things? Or has no one taken the time to answer before?
It’s been common literally for centuries before either of us were born, but most likely all of human existence. Just with animals like buffalo instead of pickup trucks.
The problem is he’s Unfortunately, short, so he has a hard time on visualizing things like the size of pick up, which are quite large
Half of the standard passenger vehicle around here.
Americans will use literally anything except the metric system 😔
There is a metric. The metric is one truck!
Go to Boston, and you will near the story about how an engineering class from MIT was asked to measure the distance across a bridge without using any established unit of measure. So this picked this guy named Smoot and counted off how many Smoots the bridge were.
For some reason, they tell this story to tourists as proof of ingenuity but it was the most pointless exercise I could imagine in engineering.
I live in Boston; I am familiar with the Smoot unit lol
So, how would you make that measurement?
The point of the lesson was to teach creative problem-solving. And a by-product of that, all measuring systems are simply arbitrary units made up by some random dude. And that in the end, no one standard is better than another. All that matters is that enough people agree upon a standard that is reproducible to a level of accuracy that is Good Enoughtm and fit for purpose.

Front or back half? They are substantially different on volume
And are we talking a reasonable work truck, or one of those American abominations referred to as ‘pickup trucks.’
falling from the the sky and burning is a good thing, bigger concern is them staying up there for too long
falling from the sky onto things is a problem tho
communication satellites are low earth orbit to reduce latency, that means +25000 km/h velocity to sustain orbit, and would also have a very shallow entry angle, that combination means total vaporization
i mean, with that many satellites what are the odds (i have the smoked 2 joints stupids) something fucks up and it doesn’t come in at that shallow entry angle?
Due to the physics and orbital mechanics, near impossible thankfully
Low earth orbit is most survivable reentry trajectory… coming in at a higher angle significantly increases the heating.
The vaporized materials themselves are a problem. When we’re building these mega-constellations, we’re putting some real mass up there. We’re introducing all sorts of exotic materials into the stratosphere that would not naturally occur there at those concentrations. And remember, this is a very sensitive environment. The actual volume of CFCs we introduced into the stratosphere wasn’t that large. The volume of all our AC refrigerant and hair spray cans was nothing compared to the atmosphere. We may actually not be that far from the sheer volume of satellites affecting the ozone layer as they decay.
The stratosphere is an environment like any other. It has a finite ability to absorb and process any form of pollution without noticeable and significant effects. I’m not qualified enough to estimate the number of satellite reentries to damage the ozone layer or to have other deleterious effects, but at least from that study featured in that video, we may not be far off. The story of civilization has been repeatedly realizing that what we once considered infinite dumping grounds were anything but. And the stratosphere is no different.
Edit: may have misinterpreted parent comment and went off on a wild tangent.
We would be pretty lucky if it impacted something like the ozone layer in a noticeable way as that’s something that can be seen and could be acted on and repaired as we’ve done before.
It’s the effects that we don’t know that are probably going to be the bigger problem.

Ah, nothing like the taste of fresh satellite in the morning!
Nothing quite like that aluminum oxide! So refreshing!
What does that have to do with orbits and reentry angle?
That’s a good question!
I think you meant to respond a couple comments up the chain.
Falling from the sky a good thing?
Ok well hope neither you nor a loved one is standing under it then. Cuz you sure aren’t hoping so. Go learn some humanity in the meanwhile.
You do know that it’ll just burn up in the atmosphere?
Most of them, there was a link in the article about one starlink satellite that didn’t completely burn up. But their biggest concern atm is what effect it will have on the atmosphere. From the article.
“What that means, though, is that all the mass of the satellites — the solar panels, plastic, metal, batteries — it’s all getting melted and deposited in the upper atmosphere. So, that’s not a good thing”
Starlink satellites are in too low orbit to completely burn up.
How awesome would it be for Donald Trump, Joe Rogan, Dana White, and Elon Musk himself to get smashed by a Musk satellite during a photo op in the octagon at the White House UFC fight.
As an atheist that would legitimately make me turn Christian.
I don’t think you’re doing atheist correctly.
If that happened, you could not convince me that we aren’t all extras in Idiocracy 2.
I mean I’m drawing on other peoples comedic talent
As awesome as RFK Jr dying of measles.
I mean, if we’re going to go with retribution-by-improbable events, I have to stick with the classics. There’s nothing quite like an evil leader being smote by lightning bolt. It just has that “wrath of an angry God” effect like nothing else.
I love how this is simultaneously a great and horrible photoshop. Like the splice is obvious in the foreground but I can’t see it in the background at all. Like I have no idea how this was done.
There’s some amount of AI-fuckery going on.
Nah, I just wasn’t looking close enough, it’s just a simple paste of one image on top of another from the same angle. If you follow the line where the truck ends upwards, you can see a similar line on the roof of the building and the tree in the background doesn’t quite line up perfectly (but it’s close enough that our brains assume it’s fine).
That might have even been done in paint rather than gimp or ps.
There is some line on the roof, but the roof still strangely lines up. The tree in the background nor the sky have a visible line.
Furthermore the text on the tire is garbled, and the whole image has this “covered in vaseline” feeling to it.
You’re right about the sky, though I think the tree does have a line but the blur hides it (I can see it when I include the line in the roof but not when I block it). I’d say that it is more sophisticated than paint, but that an image editor was used to take the cloud from only one of the images.
I disagree that the tire text is garbled. https://www.bfgoodrich.ca/en/auto/garage/articles/making-of-the-ko3-tire here’s a picture of a similar tire with the same text. AI might have been used for some of the editing of that transition, but I don’t think the source images were genAI.
The A and especially the E on “terrain” look messed up.
Thanks?
If you split it this way you end up with more than half of the weight, you need to split it down the middle through front and rear bumpers.
naa. your mom is still on the pass side.
r/AnythingButMetric
or whatever the Lemmy Syntax would be
I don’t understand what kind of capitalist pig you need to be to allow private companies access to low orbit.
just some random capitalist hereIs it regulated? What’s stopping me from putting up a satellite?
yo momma would give you such a smacking
That’s a risk I’m willing to take.
I need a banana for size comparison.
Banana is metric, Americans use raccoon penis.
Of course, I totally forgot about the new RFK Jr. measurement system. I think that is about 4 inches give or take.
thats on the large size even for people right 😥
Once again, Americans will use anything except the metric system to measure things.
and, is that half an F150 or half a Ranger?
Starlink got no plan about when and where their half pickup trucks are gonna fall.
