How did you calculate that? The question didn’t even mention a specific speed, just “near the speed of light”.

The kinetic energy for a grain of sand near the speed of light is somewhere between “quite a lot” and “literally infinity” (which is, in a sense, the reason you can’t actually reach light speed without a way to supply infinite energy).

I bet he’d quickly become less busy if he was the supreme commander of the US armed forces

The ISS has enough spacecraft docked to take everyone home at a moments notice, always. Nobody needs to launch anything.

They broke that rule briefly when the Boeing capsule was deemed unfit for use, but they quickly fixed that.

I’ve heard it’s actually really difficult, because a good translator doesn’t do it literally.

They’re supposed to say something which gets the same meaning across, which often isnt what you’d get just by translating each word.

That leaves people translating trump with a problem: you can’t generally turn his long rambling speeches into something with a clearly understandable meaning without putting words into his mouth, or summarising so aggressively that you’d only say a couple of sentences for every few minutes of speech

I’m pretty sure their concern is their own birth rate dropping, actually. Have you seen the demographics graph for Russia? They’re facing a complete collapse of their working-age population in a decade or two

No, it would have been detected by various systems pretty much immediately. Those systems are military though, and probably wouldn’t tell the general public about the movement of military satellites

It’s also conceivable that it was detected in that orbit but not recognised, so it was treated as a mystery object

By that logic, you should object to cheese being labelled as “cheddar” cheese, because that’s a place too and you’ve almost certainly never seen cheese which came from there.

It’s a stupid rule

Hey now, some of us have standards.

We have shitty python scripts

HARM is a category of weapon which seeks things like radar or jammers. They weren’t suggesting that the jammers are literally harmless.

In unrelated news: the jammers are, in fact, harmless unless you’re making a habit of riding on top of the tank. The radio energy isn’t going to penetrate a significant thickness of conductive material, such as armour plating. Or unless you’re the person being jammed, in which case they’re a different category of harmful

Destroying a nuclear sub, or a nuclear weapon, doesn’t lead to a nuclear explosion. It takes considerable care to cause a nuclear explosion, and smashing a reactor or warhead just leaves you with a pile of radioactive scrap.

Not saying that isn’t a problem, but it’s way less of a problem than a nuclear explosion

It’s amazing that people seem to be taking this comment literally

They should last indefinitely so long as the process of accretion which created these nodules keeps going. A battery becomes drained when the chemical interaction between the two metals uses up all the available metal, which happens quite fast in our modern batteries because we’ve designed them that way.

We’ve made them powerful and cheap by using relatively small amounts of each metal, spread thin and sandwiched together. The downside is that those things films of metal get used up fast.

These nodules, meanwhile, are lumps of metal. They won’t produce lots of power all at once, but they can generate small amounts for ages, and so long as they grow faster than the metal gets used up (it doesn’t actually go anywhere, it just changes chemically) they’ll keep going

I know that for two reasons: first, we already know that oxygen concentration in the deep ocean is generally pretty low compared to the surface, and second we can already account for the general composition of our atmosphere. There just isn’t a big chunk of mystery oxygen who’s source we can’t identify.

While it’s not impossible that we’re mistaken and a bunch of it is coming from somewhere other than where we expect, it’s sufficiently unlikely that I’m comfortable making such statements I told and unless presented with evidence to the contrary.

The article is being pretty hyperbolic. There’s no mystery here, this is just something which happens if you put two different metals together. It’s nothing more or less than a crude battery, just like the ancestors of the AA battery the article kept harping on about.

This discovery could be important for people studying the climate on very early Earth, people studying early life, and the ecology of the deep sea today.

That last one is particularly troubling, though. If this is widespread, then this might be a major source of what little oxygen is down there. If so, then taking those nodules away (like a lot of people are keen to do, since some of the metals they’re made of are valuable) could destroy an entire ecosystem.

More research is required

We can, it’s just electrolysis. All you need is electricity, and these nodules are simply batteries.

We’re not short of oxygen up here though, so it’s not terribly useful. We could get hydrogen that way, which would be greener than the way we get it at industrial scale now, but it would be way more expensive

They haven’t hijacked that, it’s their turn to chair it. The core members of that council take turns to do that.

You do realise that the key reason for that council to exist is so that nuclear armed powers talk to each other, right? However much we may disapprove of Russia’s wartime policies, the council is doing its job so long as there’s neutral ground where everyone else can talk to them about it rather than getting itchy trigger fingers

Because you might accidentally do something which breaks the system, or you might run a program which does something malicious without your knowledge.

By gating dangerous (or protected for any other reason) commands behind sudo, you create a barrier which is difficult to accidentally cross

Systems like that can easily be difficult or impossible to test on the ground, because they aren’t strong enough to work under gravity. They might need to be in free-fall to survive being deployed

The president can’t actually make law, as far as I understand it. He, and the various offices managed by the executive branch, apply and enforce the law which Congress has written (give or take some interpretation by the courts).

Sometimes of those laws specifically give the executive broad enough authority over something that it’s very similar to the president being able to write laws about it, but it’s not quite the same and it cant overrule actual laws

“dissolving parliament” means they’ve announced a general election. Parliament won’t meet any more, and all the existing members of parliament will go home and begin campaigning
