MOND still isn't a slam dunk as the explanation for dark matter though. In the latest PBS Space Time video about MOND, Matt talks about several aspects of dark matter that MOND is less able to explain than the competing theory that there's a new form of matter waiting out there to be discovered. He also raised the issue of the growing number of MOND models are out there as more data about dark matter comes in, and we all know how critical Sabine is of the theorists continually coming up with new models as the existing ones are shot down. She can't have it both ways! Personally, I have no skin in this game -- a solution to the dark matter problem would be fantastic whatever it turns out to be -- and I don't understand why some people (outside of those actually working or reporting on the issue) are so invested in it being one over the other.

@@EnglishMike The thing is dark matter is not really disproven at all by this either.

I mentioned this in a comment on your previous video, and I still wonder if this could have any implications in something such as quantum computing. Have you read about the Quantum Twisting Microscope developed in the Weizmann Institute of Science? I read about it on Israeli media last week, but if there's a serious development in this it would be interesting to hear a better explanation of what it might be able to be used for. It was basically stated this microscope is able to measure the quantum properties of electrons without making them collapse into particle state. It was said that instead of having a sharp nanometric tip as in a scanning tunneling microscope, it uses a 2D layer of a quantum material such as graphene to measure electron tunneling at many different locations simultaneously. This is as much as I understood.

@Dragrath1
@Dragrath1 Год назад
Things are a bit more tricky than that as one criticism that hasn't been adequately addressed by cosmologists is that within the full Einstein field equations the link between spatial look back distance and measured redshift is model dependent, i.e. depends on the curvature along the light's particular geodesic path through spacetime, thus if the choice of model is incorrect the estimates for distance will be incorrect. Given the many problems with the standard model of cosmology which have largely been ignored by the cosmological community at large despite their huge statistical significance (now several sigma standard deviations higher than the supposed evidence for the standard model) it seems safe to take anything from the mainstream cosmological community with a grain of salt at best.

I've always wondered about probability of decoherence with larger quantum computers. Couldn't it be the case, that increasing the number of qubits or gates requires exponential (or polyonmial with a high degree) amount of effort? Why does it currently happen that they decohere? Is it even the limiting factor to the size of the quantum computer? A video about that topic would be really interesting.
@Arturo-lapaz
@Arturo-lapaz Год назад
actually the effort is linear, at most logarithmic. Typically the results are probabilities, which become lower, higher variance, with increasing number of qubits, decoherence is increased as indicated. To minimize the uncertainty the computation has to be repeated .

The thing that I've heard from other channels and other individuals in similar computer science field but not specifically Quantum Computing is that for artificial intelligence to really work there's going to be a rate of error and simply if you can get that Beyond human fault you're good to go. Another proposal I saw was specifically with Quantum Computing is that they may reach a point where they have to have a discrete digital processor for certain high-precision forms of computation and in the lower Precision significantly faster things would be handled with Quantum computing

I really love your content, it's really good even compered to other sciency channels, yours is best made, best explanations, best food for thoughts.... I don't really want to say it, but your quality of footage could be better, I know, I know, its good enough for what is meant for. Anyways getting a better camera, preferably one that doesn't do chroma subsampling (4:4:4) or one that does less of it (im guessing your does 4:2:0, as it's the default for most consumer cameras at this time, so 4:2:2) would give you much better and sharper chroma key on on greenscreen, because of higher resolution in color channels. Not that long ago you couldn't get consumer camera with subsampling better than 4:2:0, you had to go professional, but because of moving the video from rec.709 to rec.2020 the producents are making now consumer cameras with much better quality.

Hi Sabine, as MOND is getting traction these "days", I wonder whether this could bring some credibility to the quantized inertia theory (which is admittedly quite controversial). I mean, despite some good predictions, MOND brings no explanations as to why the gravity is different at larger scales, while QI does (... as far as I understand it, which is not much) (*). Maybe a mind like yours could help debunk that, or at least, point to its shortcomings? (*) I understand it's relying on the Unruh effet - not observed yet - as the root phenomenon causing inertia to only "happen" above a certain acceleration level. And because this is link to the universe's horizon (I don't remember which one), it looks to me (naively) that this could also explain why the universe expanded so rapidly near the big bang. How wrong am I? :)
@Dragrath1
@Dragrath1 Год назад
Quantized inertia has some major problems which prevent it from being a valid scientific theory at this time namely that it is incompatible with some of the core axioms of mathematics used to derive all of Classical mechanics General Relativity and Quantum Mechanics and thus would require one to derive an entirely new mathematical framework in order to actually test anything or even develop basic conclusions. After all the axiom of Quantizing Inertia effectively from a mathematical perspective means that you can not use differential geometry quantities and principals in your theory. All of physics from Newton onwards is exclusively written in the language of differential equations and thus is fundamentally incompatible with any self consistent QI framework. Until a self consistent formulation of QI can be derived which can also explain why the large scale limit is consistent with differential geometric interpretations and models, QI is not able to be anything more than and idea and any framework which tries to use formulas derived and written in a language incompatible with its principal axiom is pseudoscience at best in the same way trying to use Newtonian gravity deep within the gravity well of a black hole or Neutron star is invalid.
@SupGaillac
@SupGaillac Год назад
@@Dragrath1 Thanks for the detailed explanation. It seems to me that building a new theory based on some core physical principles and deriving the ad-hoc mathematical framework wouldn't be a "first", but I understand the likelihood of a successful outcome is pretty thin :) I now curious of such an example of inconsistency ... ^^

Even if we map with physical exploration our entire galaxy, it is nothing but a speck of dust in comparison to the whole universe! We had true objective reality then the uncertainty principle would not exist... it does exist because we have no objective reality... is all subjective. I think my conclusion and explanation is the best. In order to have objective reality you need to have an observer that exist from the beginning of time all the way to the end of time and even if such hypothetical Observer exist the end of time has not came yet therefore everything is subjective... all existence is part of Singularity including math... it's all a subjective observer because the end of time has not came yet... anyways im rambling lu other version of WE...
