no experiment has ever actually seen an atom in two places at once, let alone a cat being both alive and dead, and the Dirac-von Neumann axioms do not say such things, either

The objects like boson condensates and black holes are examples of highly delocalized objects. The orbital theory of electrons says, that positions of electrons are highly delocalized and this model works well in explanation of quantum properties of molecules. Of course every electron still remains isolated pin-point particles but they're also surrounded with dense atmosphere - pilot waves which are connected mutually like metaballs. Within such a connected clouds the electrons move relatively freely and their location is objectively indistinguishable for observers from outside.

We can see the analogy of this effect in human society too, which is greatly affected with groupthink and common perceptions. Of course every individual see its own version of reality, but this doesn't mean these individual versions are solely different. The indoctrinated individuals often share common views more than its desirable in fact and their society behaves like amorphous mass which lacks individual opinions.

So that at the end our Universe isn't quite universal but it's also not quite delocalized - it's simply both and the scope of delocalization even depends on individual perspective.

The multiverse is unscientific nonsense - it's all mere speculation

Everyone from physicists like Michio Kaku to Marvel superheroes propagate the idea of the multiverse - an infinite set of parallel universes. But Jacob Barandes argues that any talk of multiverses is nothing more than wild speculation, be it in quantum mechanics or cosmology, and that physicists and philosophers are not doing the public a service by suggesting otherwise.

In dense aether model universe is random. Dimensionality is the property relying on right-angled Cartesian system of coordinates - random system is an infinitely hyperdimensional system in essence. But lower dimensions are locally more present there than these higher one due to limited information spreading - this leads to abundance of low-dimensional artifacts within observable reality. Providing that we define observable universe as a 3D (which is very reductionist view) then the higher dimensions would behave locally like traces of parallel universes. This is the reason why multiverse idea is pushed mostly by stringy theorists who are also high-dimensions supporters. Of course this is very local view, as a whole our Universe is only one, as its name implies.

This is to say, I'm not very big supporter of extradimensions and simplistic interpretations of observable universe as a low-dimensional slices of multiverse - but under special circumstances these concepts are testable and even observable. The simplest example of multiverse are multiple images of distant galaxies observed through Einsteinian lens. Another plausibly testable scenario is hall of mirror model of dark matter fluctuations.

Within quantum mechanics the many worlds interpretation has some merit, because it describes reality mediated through many tiny gravitational lenses and pilot waves made with objects in relative motion. Each object will therefore observe its own version of observable reality (though modified in very slight extent, of course). Einstein cross is holographically dual version of this effect. When objects get entangled, their pilot waves get synchronized in phase and all objects entangled would then see the same version of reality. We can see the multiverse is just another denomination for effects already recognized under another names - hence the interpretation.

In human society which is complex and highly dimensional the parallel reality has much stronger notion: the progressives and conservatives increasingly live in their alternative - but intrinsically self-consistent - versions of reality in similar way like worlds of quantum mechanics and general relativity. Literally every person can see the world a bit differently than others.

The Milky Way May Be Missing a Trillion Suns’ Worth of Mass about study Detection of the Keplerian decline in the Milky Way rotation curve

Because the Milky Way’s visible material hasn’t disappeared, one easy—and especially thought-provoking—way to explain this result is that far less dark matter is floating around than previously believed. Regarding the recent observations of unexplained deviations in stellar orbital speeds in the Milky Way edge, that cannot be explained by dark matter, slow-moving stars at the Milky Way’s outskirts suggest our galaxy may be far lighter than previously believed, with profound implications for dark matter

This headline has a strong Federal Reserve vibes... What this study - or merely its interpretation - demonstrates is the classical example of the observational perspective inversion. The dark matter effect isn't (just a) deformation of massive bodies paths (through space) effect - it's the space-time deform effect (together with paths of all massive bodies embedded in it) instead. Let me to explain...

Astronomers are already aware, that rotation of stars around galaxies doesn't fit Kepler law (to be continued). See also:

In his paper, Kerr doesn’t mince words. For instance he writes “Why do so many believe that the star inside must become singular at this moment? Faith, not science! Sixty years without a proof, but they believe!” Kerr’s argument is - to the shame of many theoretical physicists - not even a particularly difficult argument. The question is then what this physically means. There are three things that came to mind immediately:

First, just because the proof that black holes contain singularities isn’t correct doesn’t mean that the conclusion isn’t correct. It might be that this distinction which Kerr pointed out actually tells us something about the type of singularity rather than about whether they’re present or absent, and someone else will complete the proof.
The second thing to know is that there are other reasons physicists think black holes give rise to singularities which are more on the physical side. Most importantly it’s that if you compress matter beyond a certain critical density, we don’t know any force that could create enough pressure to stop it from completely collapsing.
The third thing to know is that most physicists don’t think there’s a singularity inside black holes in any case. It’s because near the singularity they expect the quantum effects of space-time to become important, but we don’t have a theory for that. What’s new about Kerr’s argument is that he says you don’t need those quantum space-time effects to get rid of singularities.

Nope. It's just click bait

Unfortunately it gets even worse. So-called energy harvesters detract publics from (research of) primary sources of energy like overunity and cold fusion. They consume more energy on background (for their production and maintenance), than they actually produce.

Laser Excitation of the Th-229 Nucleus

Scientists finally succeeded in exiting an atomic resonance with a laser in the near ultraviolet. Researchers use a laser to excite and precisely measure a long-sought exotic nuclear state, paving the way for precise timekeeping and ultrasensitive quantum sensing. It's a remarkable feat that they've been working on since the 1970s. thi

Personally I don't think that nuclear clock will be as precise as they're now claimed to be. The nuclear resonance frequencies are stable but energy transition between then (which are in range of electronvolts) not as much. Low energy always implies sensitivity to environmental noise.

Ultrahigh-mobility semiconducting epitaxial graphene on silicon carbide (preprint PDF)

The joke goes that graphene can do everything but leave the lab... Roughly speaking, graphene gets its wide bangap from underlying material which has it even wider. The semiconducting graphene thus always needs bulk layer of wide bandgap material, i.e. silicone carbide beneath it. Given the fact how multilayered the present integrated circuits are there is still big chalenge in how this monolayer sandwich can be translated into a compact still functional multilayers.

How the First Transistor Worked

With compare to common wisdom (which was widespread due to Shockley's interpretation of affairs) the first bipolar transistor was constructed rather accidentally during search for explanation of another effect. Even its inventors didn’t fully understand the point-contact transistor and textbooks and popular accounts alike tend to ignore the mechanism of the point-contact transistor in favor of explaining how its more recent descendants operate.

Tantalising hint that astronomers got dark energy all wrong

The basic assumption of standard cosmology is that dark energy is constantw with respect to time. It has turned out that this need not be the case: there are indications that dark energy evolves with time.

There were many similar hints in the recent past, reflected by claims that dark matter was more abundant in the early universe, time disappearing from universe and so on. In dense aether model expansion of Universe as perceived by Hubble red shift is the result of light scattering on quantum fluctuations and scalar waves of vacuum (i.e. intergallactic dark matter). This scattering is wavelength dependent though and as such nonlinear because the light redshifted by scattering get more prone to further scattering in avalanche-like way. This brings the notion of variable dark matter or energy.

In this clip from the BBC, Brian Cox is clearly talking about the currently most popular theory for what happened before the big bang. It’s called eternal inflation. In eternal inflation, the creation of our universe is not singular, so strictly speaking there isn’t any bang. According to this theory, our universe is created by a quantum fluctuation in a field called the “inflaton”. The inflaton creates this fluctuation, and that creates a bubble which then rapidly inflates, hence the name. At some point the inflation stops, and all the energy from the inflaton field is converted into matter. All the matter around us is created only at that point when the inflaton field dumps its energy. In the literature, this event is usually referred to as “reheating”.

What happened with Brian Cox’s explanation is that he made it sound as if the reheating is the big bang. I mean, listen to it yourself: “As inflation ended, the ocean of energy was converted into matter. Big Bang.” So basically he just used the word “Big Bang” for something completely different. It’s somewhat of a disease among science communicators that I’ve complained about before because it causes a lot of confusions, but let me not go there again. Maybe more importantly, even leaving aside that we don’t know whether eternal inflation is even correct, it doesn’t remove the Big Bang per se, it just removes the big bang in our universe.

In eternal inflation, there are infinitely many of those quantum fluctuations and each gives rise to a new universe. This entire multiverse of eternal inflation however must also have had a beginning at finite time, an then you can ask, well, what happened before that. So eternal inflation just moves the problem elsewhere.
