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.

Back in Apollo, we had a feature where you could long-press on mobile and save a screenshot with options to include usernames, number and levels of parents, and original post, amongst other things. Those were the ones I used. I also remember there was a checkbox for watermark, which defaulted to on, and which I never touched but always respected, because it never condescended to me.

Anyway, I used that feature so much that there was no Apollo without it before the ensittification.

As a user experience designer, Apollo had done a lot right that the big tech names had been doing wrong, and I’d floundered on Lemmy until the Voyager team started from that foundation.

I appreciate everything this team has done for me, but I do miss this feature. It seemed aimed straight at me, so I almost hate to bring it up, but it was beautiful and I loved it.

(I’m sorry for not saying this on Git, but I just can’t right now)

eta: you guys are the best. I love everything you’ve done. <3

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.

Removed works include Saul Bellow’s ‘Herzog’ and ‘Black, White and Jewish’; no individual reasoning given for books' removal.

The purge of books from Orange County Public Schools, in Orlando, over the course of the past semester is the latest consequence of a conservative movement across the country — and strongest in Florida — to rid public and school libraries of materials deemed offensive. While the vast majority of such challenged and removed books involve race, gender and sexuality, several Jewish books have previously been caught in the dragnet.

JTA – A global bestseller by a Jewish Holocaust victim; a novel by a beloved and politically conservative Jewish American writer; a memoir of growing up mixed-race and Jewish; and a contemporary novel about a high-achieving Jewish family are among the nearly 700 books a Florida school district removed from classroom libraries this year in fear of violating state laws on sexual content in schools.

Misinformation was extremely popular in 2023, as bad science often made global headlines. Learn the truth behind these 10 dubious stories.

KEY TAKEAWAYS

• While there have been huge scientific advances in a wide variety of aspects of physics and astronomy, there have also been wild headlines that do not reflect at all what's true in this Universe.
• No, we haven't found a room-temperature superconductor, overturned the expanding Universe or Big Bang, discovered that the cosmos is twice as old as we thought, or discovered alien technology on the seafloor.
• There has been a lot of fiction permeating science news this year, and the frustrating thing is that these untrue stories are posing as actual facts.

Here are 10 lies you may want to learn the actual truth behind.
