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.

Good on you. Thank you for seeing reason. That was objectively awful.

Been saying this for years. I’m supposed to be fine when someone wakes me up on a Saturday morning to shove Jesus up my orifice, or sends my preschooler home from school with bible pamphlets, but if I did that to them with atheism, they’d riot.

And yet somehow they’re being persecuted. Fuck them.

[–] LillyPip@lemmy.ca 10 points 2 weeks ago

They should. It’s nuts this motherfucker has the influence he does. He’s an actual dipshit who’s only able to do this because he was born into money and failed upwards. He’s a moron with outsized influence. Hold him to account, please.

I'm tired of people making light of this, I'm tired of people being passive about this,

Hey man, so am I. We’re on the same page. I’ve spent the last 10 years trying to get people to take this threat seriously. That’s why I bring up what’s happened in Europe and how the far right has been piloting their ideas there. They’ve been planning this and working out the details for decades, but they’ve also lost during some of that. My point is maybe we can look at those losses and learn some things.

Many people in the US are totally unaware of that history and haven’t seen where they’ve been stomped back down. I’m saying we can look at their losses and learn something. Chest-thumping does nothing. We should be learning.

They’ve got an advantage because whilst most democratic leaders have been trying to govern and deal with crises, they’ve been systematically testing the fences. Like velociraptors, they’ll eat everyone’s faces at the first opportunity.

You’re right – we can’t make light of this or be passive. I’ve been trying to figure out how we can collectively resist for a decade. I didn’t want Biden to step down *because the threat is so dire, I thought the antifascist coalition needed the incumbent advantage (I now think I was wrong, and the timing was perfect, putting the fascists on their back foot with very little time to turn the their titanic campaign), and even though I don’t personally like Biden, I never said that because we can’t be divided and he was better than the Nazis on the porch. But now he has and this is where we are.

I’ve been downvoted for years for saying the things you’re saying – again, I don’t get why you’re angry at me. I’ve tried to get people to see the real state of things, and I’ll not stop doing that. All I can do now is convince people to vote, because that’s the only play we have left, but I’d like even more for people to understand the real threat. And I still don’t get why you seem angry at me when we’re on the same side.

It's pretty naive to think there is any other country on the planet that could cause the world more damage if turned fascist.

I never said that, and I’m confused how you got that from my comment.

In fact, if you look through my history, you’ll see I’ve said if the US goes fascist, that will be a huge problem for the whole world.

I’m not downplaying the threat at all – quite the opposite. We’re on the same side, and I’m not sure why you’re attacking me here.

[–] LillyPip@lemmy.ca 34 points 1 month ago (27 children)

It’s a bit naive to think Western Europe hasn’t been under attack from the right wing at least as long as the US has. They’ve had wars over it that never really reached US shores, and it never really went away. All of the strategies that have been used in the US were piloted and honed in Europe – look up the activities there by Manafort, Stone, Bannon, etc. all the same names who have been implementing the shit you’re seeing in the US were active in Western and Eastern Europe years before this. It’s been going on there far longer.

It’s amazing to me that people in the US haven’t been paying attention to what’s gone on there and learning from their successes.

[–] LillyPip@lemmy.ca 2 points 1 month ago

Thank you. I’ve been saying this for years now and usually get downvoted for it, which makes me sad – not because I care about downvotes but because so many people seem not to understand that this is 1933 and we need to be all-in against fascism right now.

Biden just stepped down, so it’s even more important that we unite against the threat. I don’t care who’s on the Democrat ticket – whether it’s Kamala or anyone else, even Biden’s bitey dog – this isn’t the time to debate policy. We need to vote and convince everyone who isn’t a fascist to vote against this. If we don’t, they will kill us, and that’s not hyperbole.

Please vote.

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."

That’s objectively bullshit.

The only other option is trump. Are you trying to get people to vote for trump? If so, why?

[–] LillyPip@lemmy.ca 1 points 1 month ago (1 children)

I don’t disagree. But we’re living in interesting times.

I don’t like most of the people on the ticket I’ll be given in November, but you know what’s objectively worse? Actual fascism. Fascism always ends in genocide, and these white Christian nationalists aren’t even trying to hide it, going mask-off even before they have the power to back it up.

When fascists can be this bold and still keep their seats of power, that’s quite worrying.

As I saw someone say earlier, we’re in democracy triage.

I’d vote for Biden’s corpse before trump or not voting. We must wrest all power from the fascists before we can squabble about who’s more left.

I hope people stop believing the bullshit that’s trying to get progressives to not vote or to vote for 3rd parties. Progressives absolutely can win democrat tickets, and that’s exactly why there’s so much propaganda trying to convince people otherwise. Progressives have a lot of political power right now, and the whole system can swing left if people don’t just give up. Progressives giving up is the only play the right has.

 

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
