Still doesn't answer the question I had regarding vectors it's a rather important detail with regards to how the magnetic field behaves as opposed to how the magnetic dipole moment behaves.

Asteroid defense ideas
However I should add one can always use multiple gravity tractors. As per this NASA article suggestion. https://ntrs.nasa.gov/api/citations/20120013195/downloads/20120013195.pdf This article gives good details on craft, fuel consumption, mass difference to distance ratios etc. In a pretty easy to relate to, format.

Asteroid defense ideas
Well if you care to research the merits and disadvantages the technique is called gravity tractor. https://en.m.wikipedia.org/wiki/Gravity_tractor#:~:text=The gravitational force of a,the vehicle nor its expelled Like every potential solution there is advantages and disadvantages. So really the choice of method depends on several factors. Asteroid mass, composition. Amount of correction needed and time to provie the correction is some of those factors. Here is a research article on the technique. https://arxiv.org/pdf/physics/0608157 This method doesn't require the asteroid composition, rotation and surface properties. It really only requires trajectory, and mass terms along with sufficient time and obviously communication with said craft for course corrections etc. Those are the main advantages the disadvantage is the communication requirement , sufficient fuel and a slow process that requires a large amount of time so early warning is a priority for the method to have sufficient time. However the method works with asteroids with rotation which negates numerous other methods. (Or complicates).

I was also trying to determine if the OP was applying the dipole moment. I still hadn't gotten a response in regards to whether or not vector relations are applied at any point.

Testing for Tolerance
Granted there is likely a lot you haven't posted yet with regards to your hypothesis. I will leave the time dilation aspects to others, for the time being. The question I have is how does your theory work with Lorentz force laws? In particular regard to the cross product relations between the two as described by Maxwell equations. I'm hoping you have at some point looked at the E and and B fields under vector/spinor field treatments. Understandably you likely haven't been able to post all the pertinent details to your hypothesis yet. The equations you have posted thus far only provide scalar quantities. So understanding the vector relations between the two fields of your hypothesis would be useful. Well truthfully they will become rather essential. If your hypothesis has different relations this has huge ramifications in terms of the SM model in particular the Electromagnetic stress energy momentum tensor. So I'd like to be clear how your model handles the following formula with regards to each field \[\vec{F}=q(\vec{E}+\vec{v}\times \vec{B})\] the \(\times\) is the cross product. Not to be confused with the multiplication symbol " *" for any posts I make on this thread I will be using vector notation with \(A\cdot b\) for example being the inner product, the cross product \(A\times B\) for the cross product. I will likely not need the outer product for this discussion. for multiplication I will use \(A* B\) this is also for the benefit of other readers. Also for other readers benefit. As magnetic force as per magnetic force law \[\vec{F}_B=q\vec{v}\times\vec{B}\] there is 3 key consequences. \(\vec{v}\) is particle vector 1) As the magnetic force is perpendicular to \(\vec{v}\) it cannot change the the magnitude of the velocity. 2) as it does not have force parallel to the particle velocity it does no work. 3) Motion of a charged particle under the action of a magnetic field alone is always motion with constant speed. However it can alter the velocity direction. same relations apply between E and B.

Testing for Tolerance
I mention it as it complies with our forum rules. See the pinned threads above which contains the rules for the Speculation forum. You only need your specifics of your model not the entirety of physics lol.

Testing for Tolerance
Just keep in mind simply linking the paper isn't sufficient where possible copy paste the relevant details here so no one is required to go offsite to look over your paper. Other than that having mathematical detail is excellent we don't mind alternative theories provided they are testable (ie mathematics). We do get some pretty wacky Speculations here if you have mathematics then it's a huge help. For latex here use \[\frac{1}{2}\.] I placed a period on last command to keep from activating. Good luck

Bohmian Locality as an answer to Bell's inequalities
You would be surprised how many ppl we see that don't know how that term is applied. It's simply become habit to define it. Understanding clear logic doesn't allow one to ignore physics however. As I mentioned numerous times you still haven't addressed your faster than c signals. Anyways you seem to refuse to acknowledge that a physics model requires far more than verbal logic. It's pointless for me to continue trying to provide direction for improvement from you. Good luck with your idea as you seem to feel your idea is complete and requires no improvement I see no point in continuing. Good luck Just an FYI toroid based models at the quantum level already exist and have been tested for and are still being examined. So it will take far more than verbal logic to be convincing. Although they wouldn't be useful to you from your descriptives of your model idea. They don't make the same claims you do.

The physical cause of sound when bonds and materials fracture
Try thinking of sound due to vibration for starters then consider which materials tend to vibrate more or less than other materials. Some materials such as a tuning fork has a resonant vibration to match a specific frequency.
-
Bohmian Locality as an answer to Bell's inequalities
For example very little here really makes sense. I can only assume the first part discusses intrinsic curvature rather than extrinsic. The term dimension in physics refers to effective degrees of freedom it's not strictly a geometric axis. Though x, y,z are effective degrees of freedom so is spin color charge etc etc etc. Some dimensions can even describe a strictly mathematical effective degree of freedom. You still haven't explained how you get signals from a wave faster than c as a result of your toroids

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
Unfortunately spacetime doesn't curve on its own. One could argue how to describe R=0 till they are blue in the face. Occams nothing is as good as any other way to describe it lol.
-
Bohmian Locality as an answer to Bell's inequalities
It's really has little to do with how to verbally describe something. Anyone can claim this or that. The wording really doesn't matter. In order to confirm viability of those claims you need something beyond verbal or pictures etc. That tool is mathematics using known physics. A theory has no use whatsoever if it cannot be tested for viability. It's a simple truth I realize it's disappointing to hear that from me but I would lying to state otherwise. It's easy to describe a toriod under geometry. The mathematics exist for Bohmian guiding wave action so at least a large part of the legwork is available. That would be a good start.

Funstrating isn't it. You know somethings there but you can't define it. Any infinite quantity has a finite portion but the finite portion is outside R=0
-
If Black holes slowly evaporate over time is there a point where they stop being a black hole?
An important detail as Markus just mentioned R=0, cannot be defined The mathematics breaks down is the short hand descriptive. Its also not part of any finite group. We can't define anything particle related there as well. For the same reasons...if you can't define the spacetime the particles would reside in. Its impossible to define any particle presence

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
That's ok anyone can easily confirm the first equation is the photon propogator its in dozens of textbooks. It a standard form for the Feymann rules. Including the one I provided lmao however thanks for the support. Takes time but it can be accomplished. If you really want to learn I would start with vectors and spinors learn their components and addition rules. Then do so under field treatments. Once you do that GR becomes rather easy. To get a handle on QM and QFT statistical mechanics is the next route as it also uses the vectors/ spinors. Path integrals uses momentum space hence you need the above as its momentum space/phase space includes probability wavefunctions for all possible paths (path taken is the least action). The amplitude of that wavefunction giving the highest probability ( the weighted sum). Those probabilities are determined using Fourier transformations. QFT uses the Klein Gordon equation which is Lorentz invariant. However QM uses the Schrodinger equation which is not Lorentz invariant. This also means the photon propagator can come in different forms depending on the gauge its being applied in. There is also a couple of different forms for Feymann. So you can easily see a solid understanding of vectors/ spinors as standalone and as fields is essential and applies at all levels of physics and in every physics theory. Start there the rest will come far easier by default. should also mention calculus of variations is also applicable for integrals

That is why I don't waste my time trying if they can't take the time to show the error. I don't mind being corrected but I won't change what I've been professionally taught on someone's word without collaborative proof. Certainly not from some bland statement of being wrong without any further detail
-
If Black holes slowly evaporate over time is there a point where they stop being a black hole?
whatever you wish to believe I seriously doubt you know how to use any of the equations I mentioned nor have any real understanding of particle physics to begin with. I won't waste any of my time with you either considering I actually hold a degree in particle physics I don't need to . Go ahead mathematically show me being incorrect with the formulas I provided. Impress me beyond your bland statements of me making errors Prove your case instead of simply declaring errors. If you wish to accuse me of errors you had best back it up.

Aliens from space (split from Time to talk about UFO's or now as the military calls them UAP's?)
There is 195 Countries in the World. Plenty of those countries also have UFO sightings. They all have their own policies on classified information. So how can secrecy through classification have any real meaning on UFO's ? They also have their own research programs

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
of course if you want to avoid all that math a simpler way would be to use the Langrangian representation for the photon as opposed to the antiphoton. the relativistic Langrangian of a free photon is \[\mathcal{L}_0-\frac{\epsilon\hbar}{c}v\cdot \omega\] where \(\epsilon\) in this case is the helicity + for photon - for antiphoton. The conjugate momentum is the linear momentum \[p-\partial\mathcal{L}_0\partial v=\frac{e\hbar\omega}{c}\] the energy of the photon and antiphoton is \[H-\pm\hbar\omega-\hbar v\] + for photon - for antiphoton. \[H=p\cdot v+s\cdot \omega-L_0-s\cdot \omega\cdot v\] so now I've shown two methods that describe the same thing....if you like I can skip to the creation annihilation operator method... just let me know or you can pick up quantum field theory Demystified it has an excellent section on it. for all the previous its the QM methodology and applies their operators (position and momentum) if you have further doubts then please start a new thread so we don't hijack this one. PS probably the easiest example of how photons interact and how cross sections are applied study Thompson scatterings. Though they likely won't show the anti-photon it will demonstrate the importance of cross sections

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
You can easily confirm what I state by simply googling Shall I do it for you "Some particles, such as the photon, are their own antiparticle. Otherwise, for each pair of antiparticle partners, one is designated as the normal particle " https://en.m.wikipedia.org/wiki/Antiparticle There that wasn't too hard was it ? Took me less than 10 seconds.... As far as Breit Wigner and Fermann integrals https://pdg.lbl.gov/2011/reviews/rpp2011-rev-cross-section-formulae.pdf For Breit Wigner. Feymanns golden rule https://en.m.wikipedia.org/wiki/Fermi's_golden_rule#:~:text=In quantum physics%2C Fermi's golden,result of a weak perturbation. Anything else I can do for you? how about providing you the Feymann integral itself for the photon. photon \[i\Delta_{\mu\nu}(k)=\frac{i}{-k^2-i\epsilon}[g_{\mu\nu}-\frac{k_\mu k_\nu}{k^2}(1=\alpha)\] antiphoton \[i\Delta_{\mu\nu}(k)=-\frac{i}{-k^2-i\epsilon}[g_{\mu\nu}-\frac{k_\mu k_\nu}{k^2}(1=\alpha)\] notice the only difference is the sign so if the two encounter each other they annihilate. However that is true for every particle antiparticle pair regardless if it is its own antiparticle or has a difference in charge...μ is the polarization index rule 4 of the Feymann rules is you symmetrice between identical bosons as the anti-photon is antisymmetric to begin with you follow the Dirac rules for asymmetric particles in essence fermionic rules. you Multiply \(\mu\) with \(\epsilon^*_\mu\) for incoming particles and \(\epsilon_\mu \)for outgoing particles. \(\epsilon\) is the dimensional regularization parameter. (renormalization ).The rest of the Feymann rules I suggest you get a decent textbook on the topic. There is 10 primary rules. However their are also special rules for different theories such as \(\phi^3\) or \(\phi^4\) here is Fermi's golden rule ( prefer the format) 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 \[N=N_0\exp(-x/l_0)\] as opposed to here but they are equivalent. https://en.wikipedia.org/wiki/Fermi's_golden_rule here is some relevant details on Breit Wigner cross sections. Breit Wigner cross section \[\sigma(E)=\frac{2J+1}{2s_1+1)(2S_2+1)}\frac{4\pi}{k^2}[\frac{\Gamma^2/4}{(E-E_0)^2+\Gamma/4)}]B_{in}B_{out}\] 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 \[\beta=v/c\] c/m frame scattering angle \[\theta\] fermion charge \[Q_f\] if factor [N_c=1=charged leptons if N_c=3 for quarks. if v=c then (ultrarelativistic particles) \[\sigma=N_cQ^2_f\frac{4\pi\alpha^2}{3s}=N_cQ^2_f\frac{86.8 nb}{s (GeV^2)}\] 2 pair quark to 2 pair quark \[\frac{d\sigma}{d\Omega}(q\bar{q}\rightarrow \acute{q}\acute{\bar{q}})=\frac{\alpha^2_s}{9s}\frac{t^2+u^2}{s^2}\] cross pair symmetry gives \[\frac{d\sigma}{d\Omega}(q\bar{q}\rightarrow \acute{q}\acute{\bar{q}})=\frac{\alpha^2_s}{9s}\frac{t^2+u^2}{t^2}\] The last details I copied from my own research of with regards to Early universe processes including electroweak symmetry breaking. You can find plenty of examples of how to use them here https://www.scienceforums.net/topic/128332-early-universe-nucleosynthesis/ if you really want to learn Feymannintegrals I suggest Feynman Integrals Stefan Weinzierl https://arxiv.org/abs/2201.03593 providing precise step by step on a forum is quite frankly impossible. For example it would take literal pages to explain the Casimer trick for sum of amplitudes for the path integrals. Let alone using Feymann's trick for the integrals. thankfully tools such as Mathematica with the Feycalc package can handle those steps. PS anyone familiar with Breit Wigner may notice that the Fermi golden rule is integrated into the Breit Wigner formula

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
Well the problem with the dark matter spectrum is that indirect evidence gives all the characteristics of either a weakly interactive particle likely candidate being right hand neutrinos ( this is the main focus of my research at the Professional level) or axioms. Being weakly interactive you don't get clumping as you would with matter. So it's rather tricky to get stars made up of dark matter. As evidence points toward " does not interact with EM force." Clumping is highly unlikely. The same goes with the strong force. A weakly interactive particle may interact with other weakly interactive particles such as other neutrinos . The Higgs field for mass terms and gravity. For detection using EM any viable detection so far involves x rays due to specific interactions so we can only get indirect evidence using the EM spectrum. Other indirect evidence being the mass terms with gravity. I don't find anything beyond the above too likely but who knows I could be wrong on that. However from my research I strongly consider right hand neutrinos as the most likely candidate.

Aliens from space (split from Time to talk about UFO's or now as the military calls them UAP's?)
Agreed on that, there are cases where the witness really didn't want the attention. One would tend to give those witnesses greater credibility. Doesn't mean a mistaken identity wasn't involved etc etc. I tend to have more respect for the cases where it's clear the motivation has nothing to do than generate monetary gain or attention seeking.

Your thoughts on Neil deGrasse Tyson
I personally don't base my opinion of any physicist by how popular they are in the media etc. Yes they tend to excel at taking complex topics and simplifying for the public which is very useful and beneficial. It generates interest to help generate new students as well as enhances interest for research etc. So that's never a bad thing. However I tend to focus on their research papers etc. Neil DeGrasse papers aren't bad but someone like Sean Carroll has a wider range of recommended literature. However that's just me
-
Aliens from space (split from Time to talk about UFO's or now as the military calls them UAP's?)
One thing I learned over the years is monetary gain isn't the only reason for hoaxes or seeking fame. Many cases is simply a means to get attention. It's not just restricted to UFO sightings either but literally every aspect of science when you include all the alternate and wildly exotic articles you find on the internet.

If Black holes slowly evaporate over time is there a point where they stop being a black hole?
It's best to regard spacetime as simply the arena where the SM model of particles/fields reside. It really is simply a volume that uses the Interval (ct) to give time dimensionality of a length. Spacetime curvature under this describes the particle paths and the easiest way to understand this is to use parallel transport. (The equations of the EFE also uses parallel transport) If spacetime is flat two parallel beams of light will remain parallel. If you have positve curvature those beams will converge. If you have negative curvature they will diverge. For gravity use the same manner. Draw two lines at some distance apart and connect them to the CoM. You will notice those lines converge as you approach the centre of mass. Another useful tool to understand why particles follow different paths is to realize that all particle motion obeys the principle of least action. (This includes Feymann integrals as well as spacetime geodesics). Terms such as fabric etc gives false impressions of spacetime being some material or substance. It really is simply a metric that describes a volume and spacetime paths (null geodesics for massless particles such as photons). What affects the paths is all matter and force fields of the SM model. The coupling constants collectively give rise to the mass terms (mass is resistance to inertia change). They also have strange stars that suggest with certain neutron stars all quarks become strange quarks. Some models really stretch the imagination but surprisingly enough do have enough viability to warrant research. As for myself I study some of these as they often include unique ways to mathematically describe fields and states that I find useful for model developments. They also have papers suggesting a dark sector of a wide range of particles such as dark photons etc. Yeah I don't agree with the theory myself I ran across it a few years back.
