Without providing proof: We are not living in a 'simulation'.
I am certain of it (having analysed this before) but don't know yet how to put it in words.

(hmm.. Heisenberg's uncertainty principle & necessary information for simulation. (geological) history. living nature outside the 'simulation'. motivation. civilisation behaviour. energy use of simulation. incompatibilities of individual brains. infants. impossible technology level (by whom and from where?). and more)

It's almost as if they're looking for a new modern type of 'God' in stead of reality.
Hey Elon Musk, you should stop reading science fiction books and stop watching science fiction movies. They're fiction and so are your dreams ;)

The Most Famous Paradox in Physics Nears Its End
https://www.quantamagazine.org/the-black-hole-information-paradox-comes-to-an-end-20201029/

In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition. The work appears to resolve a paradox that Stephen Hawking first described five decades ago.

Information gets out through the workings of gravity itself — just ordinary gravity with a single layer of quantum effects. ... Muted at first, these effects come to dominate when the black hole gets to be extremely old. The hole transforms from a hermit kingdom to a vigorously open system. Not only does information spill out, anything new that falls in is regurgitated almost immediately.

The work is highly mathematical and has a Rube Goldberg quality to it, stringing together one calculational trick after another in a way that is hard to interpret. Wormholes, the holographic principle, emergent space-time, quantum entanglement, quantum computers: Nearly every concept in fundamental physics these days makes an appearance, making the subject both captivating and confounding.

... In some way or other, space-time itself seems to fall apart at a black hole, implying that space-time is not the root level of reality, but an emergent structure from something deeper. Although Einstein conceived of gravity as the geometry of space-time, his theory also entails the dissolution of space-time, which is ultimately why information can escape its gravitational prison.





... But rather than think of the wormholes as actual portals sitting out there in the universe, Mahajan and others speculate that they are a sign of new, nonlocal physics. By connecting two distant locations, wormholes allow occurrences at one place to affect a distant place directly, without a particle, force or other influence having to cross the intervening distance — making this an instance of what physicists call nonlocality. In the black hole calculations, the island and radiation are one system seen in two places, which amounts to a failure of the concept of “place.” “We’ve always known that some kind of nonlocal effects have to be involved in gravity, and this is one of them,” Mahajan said. “Things you thought were independent are not really independent.”

Wormholes crop up because they are the only language the path integral can use to convey that space is breaking down. They are geometry’s way of saying the universe is ultimately nongeometric.

Helicopter Pilot Finds 'Strange' Monolith In Remote Part of Utah
https://www.theguardian.com/us-news/2020/nov/23/helicopter-pilot-finds-strange-monolith-in-remote-part-of-utah



A mysterious metal monolith has been discovered in a remote part of Utah, after being spotted by state employees counting sheep from a helicopter.

The structure, estimated at between 10ft and 12ft high, appeared to be planted in the rock. It was made from some sort of metal, its shine in sharp contrast to the enormous red rocks which surrounded it.

Utah’s highway patrol shared images of both the sheep and the monolith.

The helicopter pilot, Bret Hutchings, told local news channel KSLTV: “That’s been about the strangest thing that I’ve come across out there in all my years of flying.”

Hutchings was flying for the Utah department of public safety, which was helping wildlife resource officers count bighorn sheep in the south of the state.

“One of the biologists is the one who spotted it and we just happened to fly directly over the top of it,” Hutchings said. “He was like, ‘Whoa, whoa, whoa, turn around, turn around!’ And I was like, ‘What?’ And he’s like, ‘There’s this thing back there – we’ve got to go look at it!’”

Hutchings said the object looked manmade and appeared to have been firmly planted in the ground, not dropped from the sky.

The monolith and its setting resembled a famous scene from Stanley Kubrick’s 1968 film, in which a group of apes encounter a giant slab.

Did Viruses Create the Nucleus? The Answer May Be Near.
https://www.quantamagazine.org/did-viruses-create-the-nucleus-the-answer-may-be-near-20201125/

Scientists generally think eukaryotes first came on the scene between 2.5 billion and 1.5 billion years ago, when evidence suggests that a bacterium took up residence inside a different kind of prokaryote, an archaeon, and became its mitochondrion. But a deeper mystery surrounds the emergence of the nucleus; no one even knows whether that ancient archaeon was already a kind of proto-eukaryote with a nucleus, or whether the nucleus came later.

Any origin story for the eukaryotic nucleus needs to explain several of its features. There’s the nature of the structure, for starters: its nested inner and outer membranes, and the pores that connect its interior to the rest of the cell. There’s also the curious way it compartmentalizes the expression of genes within itself but leaves the construction of proteins outside. And a truly persuasive origin story must also explain why the nucleus exists at all — what evolutionary pressures pushed those ancient cells to wall up their genomes.

... “What we [eukaryotes] are is a classic case of what they call emergent complexity,” explained Philip Bell, the head of research for the yeast biotechnology company MicroBioGen. Bell proposed a viral origin for the eukaryotic nucleus back in 2001 and refreshed the theory in September. “It’s three organisms that came together to make a new community, which eventually integrated to such an extent that it became, effectively, a new life-form.”  ... “Five minutes of looking and I go, ‘Jeez, if it’s an endosymbiont, it’s not a bacterial one,’” he recalled. There were just too many differences between bacterial and eukaryotic genomes, he felt, like the fact that eukaryotes have linear chromosomes while bacteria tend to have circular ones.



Bell believes an ancient giant virus infected an archaeon and set up a viral factory but didn’t kill its host cell. Instead, the structure managed to stick around. “And then the virus, which is a gene thief, stole the genes from the archaea and completely destroyed its genome,” he explained. That’s a common theme with viruses, especially giant ones — they take genes from their hosts, which makes them less dependent on their hosts. That might even help explain why so many mitochondrial genes have moved to the nucleus: “Over the years it has been stealing the genes from the mitochondria and starting to control it as well.”

So in a way, “the virus just wears the archaeon’s cell as a cloak,” Bell said. And if that model is right, he pointed out, “you could say at the heart of every human cell is a virus.”

Primordial Black Holes and the Search for Dark Matter from the Multiverse
https://phys.org/news/2020-12-primordial-black-holes-dark-multiverse.html


https://www.discovery.com/science/Universe-Inside-Every-Black-Hole

Recent progress in fundamental theory, astrophysics, and astronomical observations in search of Primordial Black Holes (PBHs) has been made by an international team of particle physicists, cosmologists and astronomers, including Kavli IPMU members Alexander Kusenko, Misao Sasaki, Sunao Sugiyama, Masahiro Takada and Volodymyr Takhistov.

To learn more about primordial black holes, the research team looked at the early universe for clues. The early universe was so dense that any positive density fluctuation of more than 50 percent would create a black hole. However, cosmological perturbations that seeded galaxies are known to be much smaller. Nevertheless, a number of processes in the early universe could have created the right conditions for the black holes to form.

One exciting possibility is that primordial black holes could form from the "baby universes" created during inflation, a period of rapid expansion that is believed to be responsible for seeding the structures we observe today, such as galaxies and clusters of galaxies. During inflation, baby universes can branch off of our universe. A small baby (or "daughter") universe would eventually collapse, but the large amount of energy released in the small volume causes a black hole to form.

An even more peculiar fate awaits a bigger baby universe. If it is bigger than some critical size, Einstein's theory of gravity allows the baby universe to exist in a state that appears different to an observer on the inside and the outside. An internal observer sees it as an expanding universe, while an outside observer (such as us) sees it as a black hole. In either case, the big and the small baby universes are seen by us as primordial black holes, which conceal the underlying structure of multiple universes behind their "event horizons." The event horizon is a boundary below which everything, even light, is trapped and cannot escape the black hole. ...

Searching for Dark Matter Through the Fifth Dimension
https://phys.org/news/2021-02-dark-dimension.html

Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz are working on a theory that goes beyond the Standard Model of particle physics and can answer questions where the Standard Model has to pass—for example, with respect to the hierarchies of the masses of elementary particles or the existence of dark matter. The central element of the theory is an extra dimension in spacetime. Until now, scientists have faced the problem that the predictions of their theory could not be tested experimentally. They have now overcome this problem in a publication in the current issue of the European Physical Journal C.

Theodor Kaluza and Oskar Klein speculated about the existence of an extra dimension beyond the familiar three space dimensions and time—which in physics are combined into 4-dimensional spacetime. If it exists, such a new dimension would have to be incredible tiny and unnoticeable to the human eye. In the late 1990s this idea has seen a remarkable renaissance, when it was realized that the existence of a fifth dimension could resolve some of the profound open questions of particle physics.

In particular, Yuval Grossman of Stanford University and Matthias Neubert, then a professor at Cornell University, showed in a highly cited publication that the embedding of the Standard Model of particle physics in a 5-dimensional spacetime could explain the so far mysterious patterns seen in the masses of elementary particles.

The Neubert group ...  found that the 5-dimensional field equations predicted the existence of a new, heavy particle with similar properties as the famous Higgs boson but a much heavier mass—so heavy, in fact, that it cannot be produced even at the highest-energy particle collider in the world: the Large Hadron Collider (LHC)

In a recent paper published in the European Physical Journal C, the researchers found a spectacular resolution to this dilemma. They discovered that their proposed particle would necessarily mediate a new force between the known elementary particles (our visible universe) and the mysterious dark matter (the dark sector). Even the abundance of dark matter in the cosmos, as observed in astrophysical experiments, can be explained by their theory.

Quantum Causality Loops
https://phys.org/news/2021-02-quantum-causal-loops.html



One of the ways in which quantum theory defies classical intuitions is by challenging our ideas of causality. Quantum entanglement can be used to produce correlations between distant experiments that are known to evade satisfactory causal explanations within the framework of classical causal models. Furthermore, a unification of quantum theory and gravity is expected to allow situations in which the causal structure of spacetime is subject to quantum indefiniteness, suggesting that events need not be causally ordered at all.

Recently, a team of researchers from Oxford and Brussels has developed a theory of causality in quantum theory, in which causal concepts are defined in intrinsically quantum terms rather than pertaining to an emergent classical level of measurement outcomes. This has offered a causal understanding of the correlations produced by entangled states. Now, they have generalized the theory to allow causal influence to go in cycles, providing a causal understanding of processes with events in indefinite causal order.

"Previously, processes with indefinite causal order were typically regarded as simply incompatible with any causal account. Our work shows that a major class of them—those that can be understood as arising from unitary processes and which are believed to be the ones that could have a physical realization in nature—could, in fact, be seen as having a definite causal structure, albeit one involving cycles," says Robin Lorenz, a corresponding author of the study. "The idea of cyclic causal structures may seem counterintuitive, but the quantum process framework within which it is formulated guarantees that it is free of logical paradoxes, such as the possibility of going back in time and killing your younger self," explains Ognyan Oreshkov from the Université libre de Bruxelles.

"Exotic as they appear, some of these scenarios are actually known to have experimental realizations in which the variables of interest are delocalized in time."

World's First Video of a Space-Time Crystal
https://phys.org/news/2021-02-world-video-space-time-crystal.html

A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope Maxymus at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic magnetization structure in a crystal.

Order in space and a periodicity in time

A crystal is a solid whose atoms or molecules are regularly arranged in a particular structure. If one looks at the arrangement with a microscope, one discovers an atom or a molecule always at the same intervals. It is similar with space-time crystals: however, the recurring structure exists not only in space, but also in time. The smallest components are constantly in motion until, after a certain period, they arrange again into the original pattern.

A Potential Model for a Real Physical Warp Drive
https://phys.org/news/2021-03-potential-real-physical-warp.html



A pair of researchers at Applied Physics has created what they describe as the first general model for a warp drive, a model for a space craft that could travel faster than the speed of light, without actually breaking the laws of physics. Alexey Bobrick, and Gianni Martire have written a paper describing their ideas for a warp drive and have published it in IOP's Classical and Quantum Gravity.

In this new effort, the researchers have taken a previous idea based on warping space-time a step further to create a model for a warp drive that they believe could be feasible in the future.

Bobrick and Martire start with the idea of an Alcubierre warp drive, a concept developed by Miguel Alcubierre in 1994—he envisioned it as spacecraft that could contract space time in front of the vehicle while expanding it behind the craft. But such a craft would require a massive amount of negative energy, which would not be feasible for a real spacecraft. Bobrick and Martire suggest instead that a massive gravitational force could be used to bend space time. The trick is finding a way to compress a planet-sized mass to a manageable spacecraft-module size in order to use its gravity. Because of the implied difficulties, a warp drive created from the model developed by the researchers could not be built today, but it does suggest that someday it might be possible.

New Research Indicates the Whole Universe Could Be a Giant Neural Network
https://thenextweb.com/neural/2021/03/02/new-research-indicates-the-whole-universe-could-be-a-giant-neural-network/



All the universe is a neural network, and all the humans merely nodes

In a thought-provoking new paper, a physicist suggests the whole universe could be a single neural network—a competing “theory of everything” that could unite quantum and classical mechanics, he says.

The core idea is deceptively simple: every observable phenomenon in the entire universe can be modeled by a neural network. And that means, by extension, the universe itself may be a neural network.

...“Would this theory mean we’re living in a simulation?” Futurism’s Victor Tangermann asked Vanchurin. “No, we live in a neural network,” he replied. “But we might never know the difference.”

If we’re all nodes in a neural network, what’s the network’s purpose? Is the universe one giant, closed network or is it a single layer in a grander network? Or perhaps we’re just one of trillions of other universes connected to the same network. When we train our neural networks we run thousands or millions of cycles until the AI is properly “trained.” Are we just one of an innumerable number of training cycles for some larger-than-universal machine’s greater purpose?

https://arxiv.org/pdf/2008.01540.pdf

... “We discuss a possibility that the entire universe on its most fundamental level is a neural network. We identify two different types of dynamical degrees of freedom: “trainable” variables and “hidden” variables.

We consider the trainable variables to argue that near equilibrium their dynamics [are] well approximated by Madelung equations and further away from the equilibrium by Hamilton-Jacobi equations. This shows that the trainable variables can indeed exhibit classical and quantum behaviors.”

A new study published in Medical Hypothesis suggests, among other things, the existence of a plausible molecular mechanism to account for a hitherto inexplicable aspect of the so-called Gaia hypothesis; a theory which proposes that the Earth is self-regulating and controlled by the community of living organisms.

The new study, with its unforgivably long title, "Possible role for microRNAs as inter-species mediators of epigenetic information in disease pathogenesis: Is the non-coding dark matter
 of the genome responsible for epigenetic interindividual or interspecies communication?", identifies transcribable elements within the so-called "dark matter" of the genome (the about 98.5% of the genome that does not code for proteins) known as non-coding RNAs. One kind of non-coding RNA identified in the study known as microRNA is believed capable of acting as a master regulator of gene expression across kingdoms.

https://www.greenmedinfo.com/blog/genetic-dark-matter-and-return-goddess

A groundbreaking new study published in Molecular Nutrition & Food Research titled, "Interspecies communication between plant and mouse gut host cells through edible plant derived exosome-like nanoparticles," reveals a new way that food components 'talk' to animal cells by regulating gene expression and conferring significant therapeutic effects. With the recent discovery that non-coding microRNA's in food are capable of directly altering gene expression within human physiology,[1] this new study further concretizes the notion that the age old aphorism 'you are what you eat' is now consistent with cutting edge molecular biology.

Breaking the Warp Barrier for Faster-Than-Light Travel
https://phys.org/news/2021-03-warp-barrier-faster-than-light.html



If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have 'exotic' physical properties such as negative energy density. This type of matter either cannot currently be found or cannot be manufactured in viable quantities. In contrast, new research carried out at the University of Göttingen gets around this problem by constructing a new class of hyper-fast 'solitons' using sources with only positive energies that can enable travel at any speed. This reignites debate about the possibility of faster-than-light travel based on conventional physics. The research is published in the journal Classical and Quantum Gravity.

The author of the paper, Dr. Erik Lentz, analyzed existing research and discovered gaps in previous 'warp drive' studies. Lentz noticed that there existed yet-to-be explored configurations of space-time curvature organized into 'solitons' that have the potential to solve the puzzle while being physically viable.

A soliton—in this context also informally referred to as a 'warp bubble'—is a compact wave that maintains its shape and moves at constant velocity. Lentz derived the Einstein equations for unexplored soliton configurations (where the space-time metric's shift vector components obey a hyperbolic relation), finding that the altered space-time geometries could be formed in a way that worked even with conventional energy sources. In essence, the new method uses the very structure of space and time arranged in a soliton to provide a solution to faster-than-light travel, which—unlike other research—would only need sources with positive energy densities. No exotic negative energy densities needed.

If sufficient energy could be generated, the equations used in this research would allow space travel to Proxima Centauri, our nearest star, and back to Earth in years instead of decades or millennia. That means an individual could travel there and back within their lifetime. In comparison, the current rocket technology would take more than 50,000 years for a one-way journey. In addition, the solitons (warp bubbles) were configured to contain a region with minimal tidal forces such that the passing of time inside the soliton matches the time outside: an ideal environment for a spacecraft. This means there would not be the complications of the so-called 'twin paradox' whereby one twin traveling near the speed of light would age much more slowly than the other twin who stayed on Earth: in fact, according to the recent equations both twins would be the same age when reunited.



"This work has moved the problem of faster-than-light travel one step away from theoretical research in fundamental physics and closer to engineering. The next step is to figure out how to bring down the astronomical amount of energy needed to within the range of today's technologies, such as a large modern nuclear fission power plant. Then we can talk about building the first prototypes," says Lentz.

Microscopic Wormholes Possible In Theory
https://phys.org/news/2021-03-microscopic-wormholes-theory.html

Wormholes play a key role in many science fiction films—often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led by Dr. Jose Luis Blázquez-Salcedo of the University of Oldenburg has now presented a new theoretical model in the science journal Physical Review Letters that makes microscopic wormholes seem less far-fetched than in previous theories.

... Previous models suggest that the only way to keep the wormhole open is with an exotic form of matter that has a negative mass, or in other words weighs less than nothing, and which only exists in theory. However, Blázquez-Salcedo and his colleagues Dr. Christian Knoll from the University of Oldenburg and Eugen Radu from the Universidade de Aveiro in Portugal demonstrate in their model that wormholes could also be traversable without such matter.

The researchers chose a comparatively simple "semiclassical" approach. They combined elements of relativity theory with elements of quantum theory and classic electrodynamics theory. In their model they consider certain elementary particles such as electrons and their electric charge as the matter that is to pass through the wormhole. As a mathematical description, they chose the Dirac equation, a formula that describes the probability density function of a particle according to quantum theory and relativity as a so-called Dirac field.

As the physicists report in their study, it is the inclusion of the Dirac field into their model that permits the existence of a wormhole traversable by matter, provided that the ratio between the electric charge and the mass of the wormhole exceeds a certain limit. In addition to matter, signals—for example electromagnetic waves—could also traverse the tiny tunnels in spacetime.

CERN Experiment Hints at New Force of Nature
https://sciencex.com/news/2021-03-evidence-physics-cern-cautiously-optimistic.html

Scientists at the Large Hadron Collider near Geneva have spotted an unusual signal in their data that may be the first hint of a new kind of physics.

The LHCb collaboration, one of four main teams at the LHC, analysed 10 years of data on how unstable particles called B mesons, created momentarily in the vast machine, decayed into more familiar matter such as electrons.

The Standard Model of particle physics, firmly maintains that the particles should break down into products that include electrons at exactly the same rate as they do into products that include a heavier cousin of the electron, a particle called a muon.

But results released by CERN on Tuesday suggest that something unusual is happening. The B mesons are not decaying in the way the model says they should: instead of producing electrons and muons at the same rate, nature appears to favour the route that ends with electrons—around 85 muon decays for every 100 electron decays.

https://indico.cern.ch/event/976688/

In physics parlance, the result has a significance of 3.1 sigma, meaning the chance of it being a fluke is about one in 1,000. While that may sound convincing evidence, particle physicists tend not to claim a new discovery until a result reaches a significance of five sigma, where the chance of it being a statistical quirk are reduced to one in a few million.

“It’s an intriguing hint, but we have seen sigmas come and go before. It happens surprisingly frequently,” Parkes said.

“I would say there is cautious excitement. We’re intrigued because not only is this result quite significant, it fits the pattern of some previous results from LHCb and other experiments worldwide,” he said.

If the result turns out to be true, it could be explained by so-far hypothetical particles called Z primes or leptoquarks that bring new forces to bear on other particles.

“There could be a new quantum force that makes the B mesons break up into muons at the wrong rate. It’s sticking them together and stopping them decaying into muons at the rate we’d expect,” Allanach said. “This force could help explain the peculiar pattern of different matter particles’ masses.”

After analyzing trillions of collisions produced over the last decade, we may be seeing evidence of something altogether new—potentially the carrier of a brand new force of nature.

New Study Sows Doubt About the Composition of 70 Percent of Our Universe
https://phys.org/news/2021-03-composition-percent-universe.html

Until now, researchers have believed that dark energy accounted for nearly 70 percent of the ever-accelerating, expanding universe.

For many years, this mechanism has been associated with the so-called cosmological constant, developed by Einstein in 1917, that refers to an unknown repellant cosmic power.

But because the cosmological constant—known as dark energy—cannot be measured directly, numerous researchers, including Einstein, have doubted its existence—without being able to suggest a viable alternative.

Until now.

In a new study by researchers at the University of Copenhagen, a model was tested that replaces dark energy with a dark matter in the form of magnetic forces.

"If what we discovered is accurate, it would upend our belief that what we thought made up 70 percent of the universe does not actually exist. We have removed dark energy from the equation and added in a few more properties for dark matter. This appears to have the same effect upon the universe's expansion as dark energy," explains Steen Harle Hansen, an associate professor at the Niels Bohr Institute's DARK Cosmology Centre.

The usual understanding of how the universe's energy is distributed is that it consists of five percent normal matter, 25 percent dark matter and 70 percent dark energy.

In the UCPH researchers' new model, the 25 percent share of dark matter is accorded special qualities that make the 70 percent of dark energy redundant.

We don't know much about dark matter other than that it is a heavy and slow particle. But then we wondered—what if dark matter had some quality that was analogous to magnetism in it? We know that as normal particles move around, they create magnetism. And, magnets attract or repel other magnets—so what if that's what's going on in the universe? That this constant expansion of dark matter is occurring thanks to some sort of magnetic force?" asks Steen Hansen.

Researchers Achieve World's First Manipulation of Antimatter by Laser
https://phys.org/news/2021-03-canadian-built-laser-chills-antimatter-absolute.html

Researchers with the CERN-based ALPHA collaboration have announced the world's first laser-based manipulation of antimatter, leveraging a made-in-Canada laser system to cool a sample of antimatter down to near absolute zero. The achievement, detailed in an article published today and featured on the cover of the journal Nature, will significantly alter the landscape of antimatter research and advance the next generation of experiments.

Since its introduction 40 years ago, laser manipulation and cooling of ordinary atoms have revolutionized modern atomic physics and enabled several Nobel-winning experiments. The results in Nature mark the first instance of scientists applying these techniques to antimatter.

... "Furthermore, we are one step closer to being able to manufacture the world's first antimatter molecules by joining anti-atoms together using our laser manipulation technology,"

'Tantalizing' Results of 2 Experiments Defy Physics Rulebook
https://phys.org/news/2021-04-tantalizing-results-defy-physics-rulebook.html

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and thrilled.

The United States Energy Department's Fermilab announced results Wednesday of 8.2 billion races along a track outside Chicago that while ho-hum to most people have physicists astir: The magnetic field around a fleeting subatomic particle is not what the Standard Model says it should be. This follows new results published last month from CERN's Large Hadron Collider that found a surprising proportion of particles in the aftermath of high-speed collisions.

The experiment, Muon g-2 (pronounced Muon g minus 2), follows one that began in the '90s at DOE's Brookhaven National Laboratory, in which scientists measured a magnetic property of a fundamental particle called the muon.

https://home.cern/news/news/physics/intriguing-new-result-lhcb-experiment-cern

... Preliminary results suggest that the magnetic "spin" of the muons is 0.1% off what the Standard Model predicts. That may not sound like much, but to particle physicists it is huge—more than enough to upend current understanding.

Researchers need another year or two to finish analyzing the results of all of the laps around the 50-foot (14-meter) track. If the results don't change, it will count as a major discovery, Venanzoni said.

... "This is not a fudge factor. This is something wrong," Kaplan said.

He explained that there may be some kind of undiscovered particle—or force—that could explain both strange results.

Physicists Working With Microsoft Think the Universe Is a Self-Learning Computer
https://thenextweb.com/neural/2021/04/09/physicists-working-with-microsoft-think-the-universe-is-a-self-learning-computer/

A team of theoretical physicists working with Microsoft today published an amazing pre-print research paper describing the universe as a self-learning system of evolutionary laws.

In other words: We live inside a computer that learns.

Dubbed “The Autodidactic Universe,” and published to arXiv today, the paper spans 80 pages and lays out a pretty good surface argument for a novel, nuanced theory of everything.

The paper argues that the laws governing the universe are an evolutionary learning system. In other words: the universe is a computer and, rather than exist in a solid state, it perpetuates through a series of laws that change over time.

The researchers explain the universe as a learning system by invoking machine learning systems. Just like we can teach machines to perform unfolding functions over time, that is, to learn, the laws of the universe are essentially algorithms that do work in the form of learning operations.

Per the researchers:

... For instance, when we see structures that resemble deep learning architectures emerge in simple autodidactic systems might we imagine that the operative matrix architecture in which our universe evolves laws, itself evolved from an autodidactic system that arose from the most minimal possible starting conditions?

We understand the laws of physics as we observe them, so it makes sense that the original physical law would be incredibly simple, self-perpetuating, and capable of learning and evolving.

The scientists describe the ever-evolving laws of the universe as being irreversible:

One implication is that if the evolution of laws is real, it is likely to be unidirectional, for otherwise it would be common for laws to revert to previous states, perhaps even more likely than for them to find a new state. This is because a new state is not random but rather must meet certain constraints, while the immediate past state has already met constraints.

A reversible but evolving system would randomly explore its immediate past frequently. When we see an evolving system that displays periods of stability, it probably evolves unidirectionally.

The consequences: If the universe operates via a set of laws that, while initially simple, are autodidactic (self-learning) and thus capable of evolving over time, it could be impossible for humans to ever unify physics.

According to this paper, the rules that governed concepts such as relativity may have had functionally different operational consequences 13.8 billion years ago than they will 100 trillion years from now. And that means “physics” is a moving target.

Conclusion: ... This all comes off a little “I just got back from the dispensary and had a few thoughts,” at first, but the researchers do a lot of leg work describing the kinds of algorithms and neural network systems such a universe would generate and, itself, be comprised of.

Well you got to fill the paper somehow. And there is a funny turnaround. The self learning computer is in a way based on humans so they are arguing that the universe could be like a human.

Or to put it another way humans and self learning systems try to find order in the system that is and then partially explain things from there. A universe does not do that or can not do that. Or so i think.  ;)

All these "we live in a simulation" theories are just another way to put humans in the middle of the universe.
Who the heck would bother to create humans for such a simulation? Who the heck would bother to create the simulation in the first place?
We are not so very interesting as we think we are.
