Mordred Posted Monday at 01:12 PM Share Posted Monday at 01:12 PM (edited) Your welcome a personal sidenote it was that very detail that got my dissertation on quintessence inflation to get invalidated wrong equation of state to observational evidence. It was written prior to WMAP using COBE dataset. A side note @MJ kihara the illusion statement you gave earlier was a Berkenstein descriptive so I cannot fault you on that. You cannot be faulted for something contained in peer review literature. Edited Monday at 01:16 PM by Mordred Link to comment Share on other sites More sharing options...

SU(3) gauge symmetry is related to strong force....I talked about strong- weak duality. Try gauge gravity duality Specifically for SU(N) N = 4 Super Yang–Mills theory and type IIB string theory on AdS5 × S5, are identical and therefore describe the same physics from two very different perspectives. In particular, if the AdS/CFT conjecture holds, all the physics of one description is mapped onto all the physics of the other. That's what the conformal element of ads/cft is describing. So now I ask which article does Ashmed specifically apply this under a mathematical treatment without resorting to someone else's work ? Anyone care to take a stab at that ? What I am trying to do is give you a far better understanding of the holographic principle but that requires significant self study to grasp One cannot do that via a forum alone. Ok simple case Take any arbitrary system A and conform it to another system B both systems have a defined boundary so you must have some translation between system A and system B The conformal element... So take an SU(N) system and conform it to a Maximally symmetric anti-Desitter spacetime there are only 3 Maximally symmetric spacetimes known De-Sitter/anti-Desitter and Minkowskii. That is the Principle basis of the holographic principle and how its applied to quantum fields. So have you ever studied string theory which would be required ? Have you studied how some point like particle property can be mapped through a mathematical space via a function which is true in string theory ? what are the boundaries of a closed string vs an open string ? how is charge mapped for start and end points in string theory ? how can one understand how the holographic principle works in ADS/CFT if they can't answer those questions ? You have to study from the start of how the theory is developed rather than jumping to the end.... The most important part the physics of system A must be identical to the physics of system B In order to be conformed... If you want to understand String theory I suggest String theory Demystified by David McMahon its about the easiest textbook on String Theory I have encountered How am I confident the OP paper doesn't involve the holographic principle ? its simple the Langrangian forms he provided do not include any terms for SUSY. In essence the entire discussion on the holographic principle has been nothing more than trying to fit personal favorite theories into someone else's model. 1 hour ago, JosephDavid said: Actually, vacuum dilute as well according to recent study by DESY https://www.quantamagazine.org/dark-energy-may-be-weakening-major-astrophysics-study-finds-20240404/ I recommend you don't rely on pop media coverage every theory always has competing theories that's all part of the scientific method.

SU(3) is just SU(3), a continuous group characterised in several ways: Its structure constants (commutation relations between generators), fundamental definition: 3x3 complex unitary matrices with det=1, etc. Strong force, OTOH, implies a coupling constant. There could be two copies of SU(3), both locally gauged (not global gauge group, like, eg, baryon number, but local, like EM), and each with a different coupling constant. One strong, and the other one very, very feeble. Almost undetectable. Why not? 3 hours ago, MJ kihara said: I talked about strong- weak duality. There is no such thing if by 'duality' you mean Maldacena duality. There is a strong-coupling to weak-coupling duality in superstring theory. Sharks can be fish, and they can be dishonest money loaners too. The word in itself doesn't clarify the situation. As @Mordred says, 18 hours ago, Mordred said: It's all the glamour kings that treat it as an illusion the metaphysics wannabe physicists. The ones that pay more attention to verbal descriptions than the mathematics. 'Moving the goalposts' does not even start to describe what's going on here.

It doesn't imply 'strong'. Link to comment Share on other sites More sharing options...

That's (more than likely) because you feed into the Maldacena conjecture theories that are related by S-duality in superstring theory, not because (or not necessarily so) of the correspondence itself (take good notice of the word 'when' in your quote). The correspondence itself seems to be something equally deep and perhaps not totally understood yet, although the holographic principle could well be a unifying / synthetic principle explaining it. Those are difficult ideas with considerable conjectural stretching at the seams. Wikipedia articles are accessible to all, full of references, valuable for many reasons. But clarity is not always one of them. That's part of the reason why I try to avoid using Wikipedia articles in order to argue anything, but just in order to attach a working definition for a term I have to mention. 5 hours ago, MJ kihara said: I like wikipedia because it's easily accessible to the public domain. I don't like it so much (although I sure use it) because it's sometimes (or can be) rather obscure. I remember a seminar by Neil Turok in which he practically ended up dissuading his students from reading the Wikipedia article on Noether's theorem, because after many paragraphs the simple idea that off-shell symmetries imply on-shell conservation laws was not displayed at all in the article, while the reader ended up probably confused by the inordinate amount of side tracks and embelishments. 6 hours ago, MJ kihara said: 12 hours ago, joigus said: I've seen many, many 'earth-shattering' discoveries come and go: Antigravity, cold fusion, superluminal neutrinos, and what not I haven't seen anyone in the thread claiming that.

So you don't find it distracting trying to add theories not in the original paper to begin with ? The entire discussion of the holographic principle was a literal distraction as it's not in the OP paper. The OP paper had nothing more complex than a little QFT and QED that where it should have stayed. However everyone tried injecting other possibilities through other referenced articles. Forcing everyone to guess and make random assertions. Edited Tuesday at 04:11 PM by Mordred Link to comment Share on other sites More sharing options...

Since you liked the last video, I'll post another on the viability of the Planck scale cut-off ... The author’s proposal is tied directly to some very solid experimental facts. We all know that the proton has never been observed to decay. That’s crucial. It means that, practically speaking, the proton is a stable structure, which strongly suggests that there’s something fundamental about its existence. Now, pair that with the third law of thermodynamics, which implies that as we approach absolute zero, there should always be some kind of remnant volume that doesn’t just vanish or break down. This tells us that there’s an unbroken, stable structure remaining even at the lowest energy states. Now, what the author is doing is connecting these dots: if there’s a remnant volume, and we know that protons don’t decay and are associated with SU(3) symmetry, then it makes perfect sense to use the volume of the proton as the benchmark for this remnant state. The SU(3) symmetry is unbreakable, it remains stable even when other symmetries like U(1) are broken near zero kelvin. That’s what makes protons so fundamental. The author matches this remnant volume, implied by the third law with the proton volume, defining SU(3) units or vacuum atoms. These SU(3) units can be used to explain why the vacuum energy doesn’t explode to some ridiculous value like QFT tells us it should. Instead, it’s spread out across these stable SU(3) units, bringing the predicted value right down to what we actually observe as dark energy. So, what’s being overlooked here is that this whole approach is anchored in solid principles: the experimental stability of the proton, the third law of thermodynamics, and the fundamental unbreakability of SU(3) symmetry. The author isn’t skipping the foundations—he’s grounding the whole argument in them. It’s about finding a stable, unbroken remnant that matches what we see in nature, and that’s why using the proton volume as the basis makes so much sense. This is what lets the author solve the cosmological constant problem with high precision. Link to comment Share on other sites More sharing options...

Mordred Posted Tuesday at 10:46 PM Share Posted Tuesday at 10:46 PM (edited) Let me ask you a question. IF i handed you the entire Langrangian for the entire standard model and merely made claims from that Langrangian of say Oh this solves the cosmological constant problem without showing you how to extract the relevant variables and showing how it does so. Would you believe me ? The Standard model Langrangian is rigidly tested so its quite capable of doing so. However why would you believe me if I don't show precisely how it does so?

No math. Physics is fundamentally an empirical science, its foundation is built on measurements, observations, and experiments. It’s not about math for math’s sake; instead, math is just a language we use to describe physical phenomena. The real core of physics exists in connecting these descriptions to what we can actually measure. In this paper, the author uses the math of spontaneous symmetry breaking and Snyder’s quantum spacetime, not as ends in themselves, but as tools to explain real, observable phenomena. The achievement here is in how the author finds logical connections between these physical measurements, uniting them in a simple, coherent relationship. This isn’t about whether there’s enough math and adding several complications, it’s about whether the math helps us understand and explain the empirical data we observe. The author managed to do exactly that, building a bridge between very solid physical concepts that leads to a clearer understanding of the universe, grounded in what we can actually measure.
