With public figures, the bar to meet slander/libel includes that it must have been done with ‘actual malice’ – not anything different about which words were used.

Private figures must show that the defendant acted "negligently.“

Public figures must show that the defendant acted with "actual malice."

The bar for bringing such a case is even higher for public figures than private people, but it’s still not about the word ‘lie’ vs ‘untruth’.

If you’re aware of a single case where synonyms like that mattered, I’d love to know.

The law doesn’t make that distinction, though. ‘Untruth’, falsely claimed’, and ‘lied’ are all the same under the law. The only thing those laws care about is whether your words were true. If I call you a liar in a headline and I can prove you actually lied, you have no case.

Weasel words don’t protect them from lawsuits, it’s just another part of the degradation of journalism and the fact that whitewashing and softening their language gets them more clicks & eyeballs, because it’s less likely to offend people who disagree.

This reeks of IN MINECRAFT, though, and we all know how mentally unstable and trigger-happy some in his cult are. This will almost certainly lead to death threats against her, if not actual plots.

The only legal excuse for this is the slander/libel laws, which only apply in cases where calling someone a liar is untrue. If you’re calling out verifiable lies as lies (e: and you can bring receipts, which they can), that’s not slander.

They’re just pussies.

Biden was far from my choice, too, but I’d have voted for his corpse to keep the fascists out of office. Harris is a no-brainer. I hope she keeps bringing up the abortion issue in the personal, relatable way she did in this debate, with specific, verifiable examples of the real human toll the right-wing cruelty has wrought.

Women and girls unable to get care because hospitals are afraid of litigation, women forced to become walking coffins. She’s right, it’s unconscionable.

That seems like the riskiest click ever. I’d have to thoroughly sterilise my phone.

Yes, that’s the minor dent I was referring to. They’d need to find another front-man. I wouldn’t be surprised if it took less than a week to convince Musk to take on the mantle.

e: the right is plenty enamoured with Musk, so I think the transition would be fairly smooth.

Let’s not give Pence more credit than he deserves. Pence didn’t decline to support Trump out of a sense of duty or because he cares about Americans, but because Dan Quayle (!) told him he had no choice in the matter:

Over and over, Pence asked if there was anything he could do.

'Mike, you have no flexibility on this. None. Zero. Forget it. Put it away,' Quayle told him.

Pence pressed again.

‘You don't know the position I'm in,' he said, according to the authors.

'I do know the position you're in,' Quayle responded. 'I also know what the law is. You listen to the parliamentarian. That's all you do. You have no power.'

source: How Dan Quayle saved democracy. Yes, really.

What if life naturally evolves towards time-travel as it begins to understand the geometry of the universe? What if the way to travel more than one direction in time lies in our ability to perceive time in the first place? That’s biological, universal, measurable, and therefore quantifiable – and so far, most things we can quantify, we can manipulate.

 

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level.

Time may not be a fundamental element of the universe but rather an illusion emerging from quantum entanglement, a new study suggests. 

Time is a thorny problem for physicists; its inconsistent behavior between our best theories of the universe contributes to a deadlock preventing researchers from finding a "theory of everything," or a framework to explain all of the physics in the universe. 

But in the new study, researchers suggest they may have found a clue to solving that problem: by making time a consequence of quantum entanglement, the weird connection between two far-apart particles. The team published their findings May 10 in the journal Physical Review A

"There exists a way to introduce time which is consistent with both classical laws and quantum laws, and is a manifestation of entanglement," first author Alessandro Coppo, a physicist at the National Research Council of Italy, told Live Science. "The correlation between the clock and the system creates the emergence of time, a fundamental ingredient in our lives."

My cat needed to be euthanised last month, and I just received her ashes. They came with a round black sticker. What’s the purpose of this sticker?

They mentioned my chosen urn was suitable for sprinkling cremains (I don’t plan to do that) – maybe it’s related to that?

Thanks.

 

A team from TU Dortmund University recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.

The results have been published in Nature Physics.

Paper abstract – Robust continuous time crystal in an electron–nuclear spin system:

Abstract
Crystals spontaneously break the continuous translation symmetry of free space. Analogously, time crystals lift translational invariance in time. Here we demonstrate a robust continuous time crystal in an electron–nuclear spin system of a semiconductor tailored by tuning the material composition. Continuous, time-independent external driving of the sample produces periodic auto-oscillations with a coherence time exceeding hours. Varying the experimental parameters reveals wide ranges in which the time crystal remains stable. At the edges of these ranges, we find chaotic behaviour with a lifted periodicity corresponding to the melting of the crystal. The time crystal state enables fundamental studies of nonlinear interactions and has potential applications as a precise on-chip frequency standard.

 

This only works by phone. Be nice, but firm. Don’t be satisfied with their first answer – make them escalate you to the retention department. They’re often authorised to give much larger discounts because it’s cheaper for them to retain customers than to recruit new ones.

 

Excess oxygen is actually harmful to humans, ~~but all the climate warnings are about losing oxygen, not nitrogen~~ edit: but when we look for habitable planets, our focus is ‘oxygen rich atmosphere’, not ‘nitrogen rich’, and in medical settings, we’re always concerned about low oxygen, not nitrogen.

Deep sea divers also use a nitrogen mix (nitrox) to stay alive and help prevent the bends, so nitrogen seems pretty important.

It seems weird that our main focus is oxygen when our main air intake is nitrogen. What am I missing?

edit: my climate example was poor and I think misleading. Added a better example instead.

 

In the movies, time travelers typically step inside a machine and—poof—disappear. They then reappear instantaneously among cowboys, knights or dinosaurs. What these films show is basically time teleportation.

Scientists don’t think this conception is likely in the real world, but they also don’t relegate time travel to the crackpot realm. In fact, the laws of physics might allow chronological hopping, but the devil is in the details.

If a person were to hang out near the edge of a black hole, where gravity is prodigious, Goldberg says, only a few hours might pass for them while 1,000 years went by for someone on Earth. If the person who was near the black hole returned to this planet, they would have effectively traveled to the future. “That is a real effect,” he says. “That is completely uncontroversial.”

Going backward in time gets thorny, though (thornier than getting ripped to shreds inside a black hole). Scientists have come up with a few ways it might be possible, and they have been aware of time travel paradoxes in general relativity for decades. Fabio Costa, a physicist at the Nordic Institute for Theoretical Physics, notes that an early solution with time travel began with a scenario written in the 1920s. That idea involved massive long cylinder that spun fast in the manner of straw rolled between your palms and that twisted spacetime along with it. The understanding that this object could act as a time machine allowing one to travel to the past only happened in the 1970s, a few decades after scientists had discovered a phenomenon called “closed timelike curves.”

“A closed timelike curve describes the trajectory of a hypothetical observer that, while always traveling forward in time from their own perspective, at some point finds themselves at the same place and time where they started, creating a loop,” Costa says. “This is possible in a region of spacetime that, warped by gravity, loops into itself.”

“Einstein read about closed timelike curves and was very disturbed by this idea,” he adds. The phenomenon nevertheless spurred later research.

Science began to take time travel seriously in the 1980s. In 1990, for instance, Russian physicist Igor Novikov and American physicist Kip Thorne collaborated on a research paper about closed time-like curves. “They started to study not only how one could try to build a time machine but also how it would work,” Costa says.

Link to study paper: Nonclassical Advantage in Metrology Established via Quantum Simulations of Hypothetical Closed Timelike Curves

Abstract:

We construct a metrology experiment in which the metrologist can sometimes amend the input state by simulating a closed timelike curve, a worldline that travels backward in time. The existence of closed timelike curves is hypothetical. Nevertheless, they can be simulated probabilistically by quantum-teleportation circuits. We leverage such simulations to pinpoint a counterintuitive nonclassical advantage achievable with entanglement. Our experiment echoes a common information-processing task: A metrologist must prepare probes to input into an unknown quantum interaction. The goal is to infer as much information per probe as possible. If the input is optimal, the information gained per probe can exceed any value achievable classically. The problem is that, only after the interaction does the metrologist learn which input would have been optimal. The metrologist can attempt to change the input by effectively teleporting the optimal input back in time, via entanglement manipulation. The effective time travel sometimes fails but ensures that, summed over trials, the metrologist’s winnings are positive. Our Gedankenexperiment demonstrates that entanglement can generate operational advantages forbidden in classical chronology-respecting theories.

 

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.

We are not proposing a time travel machine, but rather a deep dive into the fundamentals of quantum mechanics. – David Arvidsson-Shukur
