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.
