Why you deleted my posts??? Your modern country will be lost.
have you ever stopped to consider a science forum is the wrong place to post anything in regards to spy service etc. This site is to discuss science it has nothing to do with how governments are run. Nothing you have presented involves any scientific discussion. Your advertising in the wrong forum and the wrong manner. If you have been doing the same thing on other forums then its no wonder your account is getting banned in them.

Twin paradox (split)
there is no absolute frame of reference that in itself is not supported by mainstream physics hence one of the reasons why this is in speculation and not mainstream physics. An absolute frame doesn't even exist in any quantum treatment with regards to decays and aging. Those formulas you claimed do not matter in fact show the above quotation as false.

Twin paradox (split)
Yes I stated as such but you seem to be trying to include those factors in terms of the twin paradox. As I mentioned before the primary purpose of the twin paradox is to distinguish between the first order velocity terms and the second order acceleration terms resulting in the solution of the paradox which was never a paradox to begin with but amounts to improper examination by ignoring the second order terms. If you recall you kept bringing up factors such as Higgs ZPE etc. Hence I'm showing that while related has nothing to do with solving the paradox.

A nail in the coffin of Loop Quantum Gravity, or just a tack in its rubber sole?
I wouldn't go quite so far as to state the article conclusively shows the Lorentz invariance violations of LQC as being inaccurate it certainly supplies strong constraints on any Lorentz invariance violations. Which does include LQC. I would think there will be subsequent rebuttals in defense of quantum gravity models with inherent LIV being published so for myself I will wait and see the rebuttals which I fully expect. though this certainly isn't the first attempt to find evidence of spin foam using cepheids. All other attempts have also failed AFIAK. In one of the earlier examinations it was argued that the spin-foam lattices were too miniscule to have an measurable effects in signal propagation. This was in regards to one of the earlier tests resulting from a supernova event.

Twin paradox (split)
Swansont and I cross posted the distinctions for the turnaround is presented in the Ryder article I posted. There is a way to show muon decay that doesn't even involve the twin paradox in terms of gamma factor effects the twin paradox isn't needed to explain why particle decays are affected by its momentum terms such as velocity explaining why time is variable isn't part of the twin paradox. The primary use of the paradox is to help understand the distinctions between the first order terms (inertial frame/constant velocity) and second order terms (non-inertial frames/ acceleration) One can readily show for example the decay rates of the Muon using Fermi's Golden rule for the gamma factor corrections. as this is something I already have in latex form I'm going to time save a bit Fermi's Golden Rule \[\Gamma=\frac{2\pi}{\hbar}|V_{fi}|^2\frac{dN}{DE_f}\] density of states \[\langle x|\psi\rangle\propto exp(ik\cdot x)\] with periodic boundary condition as "a"\[k_x=2\pi n/a\] number of momentum states \[dN=\frac{d^3p}{(2\pi)^2}V\] decay rate \[\Gamma\] Hamilton coupling matrix element between initial and final state \[V_{fi}\] density of final state \[\frac{dN}{dE_f}\] number of particles remaining at time t (decay law) \[\frac{dN}{dt}=-\Gamma N\] average proper lifetime probability \[p(t)\delta t=-\frac{1}{N}\frac{dN}{dt}\delta t=\Gamma\exp-(\Gamma t)\delta t\] mean lifetime \[\tau=<t>=\frac{\int_0^\infty tp (t) dt}{\int_0^\infty p (t) dt}=\frac{1}{\Gamma}\] relativistic decay rate set \[L_o=\beta\gamma c\tau\] average number after some distance x \[N=N_0\exp(-x/l_0)\] Another related relation being the Breit-Wigner distributions. \[\sigma(E)=\frac{2J+1}{2s_1+1)(2S_2+1)}\frac{4\pi}{k^2}[\frac{\Gamma^2/4}{(E-E_0)^2+\Gamma/4)}]B_{in}B_{out}\] E=c.m energy, J is spin of resonance, (2S_1+1)(2s_2+1) is the #of polarization states of the two incident particles, the c.m., initial momentum k E_0 is the energy c.m. at resonance, \Gamma is full width at half max amplitude, B_[in} B_{out] are the initial and final state for narrow resonance the [] can be replaced by \[\pi\Gamma\delta(E-E_0)^2/2\] The production of point-like, spin-1/2 fermions in e+e− annihilation through a virtual photon at c.m. \[e^+,e^-\longrightarrow\gamma^\ast\longrightarrow f\bar{f}\] \[\frac{d\sigma}{d\Omega}=N_c{\alpha^2}{4S}\beta[1+\cos^2\theta+(1-\beta^2)\sin^2\theta]Q^2_f\] where \[\beta=v/c\] That should be sufficient to demonstrate that particle decay rates do require the twin paradox to explain and that it is the beta correction \[\beta=v/c\] with the above that explains the difference in the decay rate. It should become obvious that it isn't the acceleration that determines the differences in decay rates but the differences in the velocity term in regards to the beta function. here is a reference using the above specific to muon decay https://web.njit.edu/~sirenko/Phys450/MU.pdf page 11 and 12 it should be trivial to relate the above to inertial mass and gravitational mass equivalence in terms of the gamma/beta functions (shown in the link )

Twin paradox (split)
I've always liked the solutions using redshift/blueshift it does help simplify matters but also introduces the distinctions between longitudinal and transverse Doppler effects. Though another solution I liked was by Ryder Lewis in his Introduction to GR in that he will show the distinctions between the constant velocity cases and the constant acceleration case for the twin turnaround under the four momentum and four acceleration. Which is useful given that in accordance to the weak equivalence principle \(m_i=m_g\) he provides the details to further show acceleration due to gravity has equivalence to inertial acceleration this is a preview print but it has the relevant section page 26 is where he details the twin paradox https://api.pageplace.de/preview/DT0400.9780511577468_A24404000/preview-9780511577468_A24404000.pdf the hyperbolic relations he derives is useful specifically in regards to constant acceleration \[x^2-c^2t^2=\frac{g^4}{c^2}\] the next chapter goes into the Sagnac effect leading from the twin Paradox then examining the Sagnac effect.

Twin paradox (split)
Along with the reply by Swansont. It may surprise you that under field treatment at the quantum level you don't apply GR as its far too weak to have any significant influence. Hence even under QFT all particle interactions and couplings for all particle fields the equations only apply SR. The couplings directly relate to the mass terms naturally. However the Schrodinger equation is not Lorentz invariant so one must use the Dirac equations for QM/QFT which incorporates the the Klein-Gordon equation. However none of that is necessary for solving the twin paradox for the reasons mentioned by Swansont primarily different observers measuring an object does nothing to alter the properties of the object being measured. It only influences how its being measured not the object itself. It sounds to me like you may also be trying to describe variant mass (relativistic mass) as opposed to invariant mass (rest mass), the terms in the brackets is the old terminology and yes both mass and energy are variant to the observer your GR application required to handle the inertial mass terms that being the need for a stress energy momentum tensor. So yes the use of GR with the stress energy momentum term is certainly a large bonus under GR however GR uses the same SR transformations including all the Minkowskii metric transformations. Under GR the Minskowsii terms are part of the Newton weak field limit \[g_{\mu\nu}=\eta_{\mu\nu}+h_{\mu\nu}\] this of course all applies to the SO(3.1) Poincare group so yes in that sense GR does become more useful to describe the inertial mass in terms of different observers in particular for the inclusion of the stress energy momentum term however there is also nothing to prevent SR from also employing the stress energy momentum tensor which it already does. It should be indicative that the distinctions between SR and GR become more trivial when you consider the same transformations apply to both it becomes more a matter of practicality. Particularly since any quantum examination under QFT employs the weak field limit under the same EFE statement above including the SO(3.1) group. little side note one also shouldn't forget that those transformations differ depending on the type of acceleration change in velocity or change in direction. However there is no real need to understand or use any tensor to understand the velocity as opposed to acceleration relations in the solution for the twin paradox.

Earth Mass Increase by the Sun
That link pulls a different YouTube video not that it matters as one should never trust YouTube videos to begin with. Anyways if you factor in the number density of Cosmic radiation from the sun then the clearing of those rays from the magnetic field. Any charged particles from the Sun reaching the Earth's surface is negligible in terms of any potential mass gain compared to the losses mentioned above

Twin paradox (split)
What you described above is wrong. For starters you don't require the Higgs field at all for the twin paradox. Under constant velocity the choice of observer and emitter makes no difference as the Lorentz transforms under SR are symmetric under change in vector. Once you have acceleration that isn't true anymore. It was not factoring in the acceleration terms that led to the twin paradox. The constant velocity ignoring the acceleration. Once you include the acceleration the solution becomes apparent.

Earth Mass Increase by the Sun
I would find that difficult to believe as well. Particularly since a large quantity of charged particles from solar winds get deflected by our magnetic field. Secondly there are studies that show Earth has a net loss due to atmospheric escape which is greater than infalling material such as from asteroids, dust etc. You can go through the references this wiki link uses. https://en.m.wikipedia.org/wiki/Earth_mass#:~:text=Earth's mass is variable%2C subject,4 long tons) per year. Do you have a reference ?

split from Parameters of Theory of everything.
Sure if I wanted to argue with ChatGpt. A textbook itself would be a better resource to learn from. There isn't much more to say, we haven't confirmed 100 percent on either issue. When you get right down to it no theory is ever 100 percent. Our best evidence is our best evidence. Till something better comes along that's what we have to work with
-
split from Parameters of Theory of everything.
The decay rate far exceeds the age of the Universe. How would one fulfill that ? The evidence supports the decay rate but there has never been an observed decay afiak
-
Parameters of Theory of everything.
Thankfully decay rates are essential to determine when a particle drops out of thermal equilibrium. Though it's oft described as "when the expansion rate exceeds the reaction rate" in Cosmology applications.

It doesn't if you actually understand the paper is examining the different possibilities. Then later on provides the reasons why SR or GR alone is insufficient as neither account for the observer nor the equations of state. This is beginning to sound much like another sockpuppet attempt quite frankly. It doesn't if you actually understand the paper is examining the different possibilities.

If your referring to the screenshot from. The Lineweaver and Davies article. Once you read the full article and examine the mathematics the article itself will tell you precisely what I described. Never rely on part of any article without examining the full article.

Parameters of Theory of everything.
One of my favorite articles regarding GUT (grand unification) which is oft described as a TOE if one can complete the GUT including gravity is by John Beaz. It's an interesting and informative reading I highly recommend it. http://arxiv.org/pdf/0904.1556.pdf

Is time getting faster?
Yeah that was annoying to say the least. What is tricky about the FLRW metric is that proper time is effectively tied to the scale factor for determination of Cosmic time. The Cosmic time being to the commoving observer. Hence the scale factor connection. Unfortunately it's easy to mistakenly think that the time dilation formulas work with cosmological redshift but the truth is once you get recessive velocity that exceeds c. One should instantly recognize something is wrong. Unfortunately in nearly every argument I have ever had on this topic. The posters pushing their personal theories typically wish to ignore that relevant detail. Let alone any math involving GR which quite frankly the stress energy momentum yemsor components will tell one that there is no gravitational time dilation involved. (The only entry being the energy density at T_{00}.) Unfortunately too often posters rely on verbal descriptives and seek statements from articles to support their beliefs but don't recognize the math shows a different story from the verbal descriptives. Spacetime being another common misconception with the fabric descripitives. Once one studies the mathematics one recognizes there is no spacetime fabric and spacetime is simply a volume where time is given dimensionality of length via the Interval.

Yeah that's the one lol needless to say it's far more convenient to extract the terms and relations needed lol.

Parameters of Theory of everything.
You would never be able to account on a single theory cover everything. The most one can reasonably expect under physics is as described above by Joigus, myself and Migl. In essence every fundamental particle interaction encapsulated under the groups of the irrep equation I posted above with the addition of a renormalization for gravity. Even with that irrep equation one doesn't calculate from it. It encapsulates numerous formulas under each group irrep including numerous tensors too many to list.
