Probability amplitudes,coeffecients and wave function collapse.
Easy way is to consider a classic example if you determine some probability function for simplicity lets just use coin tosses but dropping a collection of coins in a given time frame. This forms a time or time independent wavefunction depending on drop rate. Once you make measurements ie number of coins with heads up as opposed to heads down. The original wavefunction isn't needed you have made determinations through observation and measurement you now have a determined wavefunction as opposed to a probability wave function. Some often refer to the latter as simply waveform to avoid confusion with the probability characteristic of a wavefunction.

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
This post had nothing to do with your article. I simply thought it was an idea you could make use of. Good luck. You want thinking outside the box its simple any mathematical methodology that can accurately describe a system or state has validity. You dont need tensors to do GR its simply another handy mathematical tool. You dont need to use 4 parameters to describe spacetime you can use parametric equations to reduce them. Thats my view point

We are tricked by our brains
Here's an interesting trick for you then take the equation of motion for a mechanical spring. If you compare the equation for the quantum harmonic oscillator you will find the precise same relations albeit a change in variables applied. The ratios of change are identical. If you study deep enough you will find a great deal of similarities between the seemingly complex equations have similar relations to many classical physics formulas commonly used in engineering. This is quite a bit more complex first and foremost the conservation rules require a closed system or a closed group. To go into greater detail would be more suitable to a seperate thread and such a discussion can get extensively lengthy. In some treatments involving spacetime one can define a conserved system usually ties into innvariance of a quantity. This is often done under local geometry in some mathematical space or manifolds. Anyways best left for a different thread

We are tricked by our brains
When I first started physics one of my earlier goals was to solve DE as an optical illusion. I realized early enough that doing so required mathematics and a good understanding of the FLRW metric and GR. In those studies I learned a valuable lesson. Simply because something doesn't make sense to you doesn't mean its incorrect. Its a lesson I carry on to this very day. More enough enough if one studies why the physics professional community states what they state there is always numerous supportive as well as counter arguments or methodologies supporting one theory or another. To a layman this unfortunately gives a rather daunting task of sorting through. Though the effort of doing so with an open mind can lead one to learn a great deal. The biggest challenge is avoiding any personal bias. Once you form a solid opinion of I feel it should be this way. One tends to close the book on examine other possibilities. This goes for any physics theory or model. The effort to understanding why physics describes something a certain way always has very strong reasoning behind it and those reasons are typically best understood by studying the related mathematical proofs. Its one reason I study not just mainstream models and physics but study numerous potential models or theories. You would be amazed that with enough studying how much something that originally sounded ridiculous starts to make sense. One also discovers how truly interconnected one theory is to numerous others. A simple change in one theory can often have numerous ramifications of dozens of others. Something many of our typical crackpot dont fully recognize. There's a simple consideration no theory or model ever becomes considered mainstream physics without years of rigorous testing and years of sorting the best fit to observational evidence. Eureka moments are typically something that only exists in movies. Theory and model building for a robust theory takes an incredible amount of work and whats often forgotten. One of the most valuable practices is that a good theorist should spend far more time proving his own theory wrong than he/she did in developing it. Little hint here if one studies statistics and statistical mechanics. One discovers that a great deal of the more difficult terminology used in QM and QFT actually originates from classical statistics. Examples being superposition, correlation functions the list goes on. It does help pull a lot of the mystery out of QM.

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
There is a handy simplification related to the non linearity of the relativistic addition of velocities where the Lorentz transformations matrix comes in handy. Rapidity using rapidity velocity is replaced by rapidity and becomes linearly additive. The method applies the hyperbolic spacetime diagram of the Minkowskii metric its also useful for a constant accelerating object. Not sure if that would interest you or not but its a useful simplification on calculations with regards to Lorentz transformations.

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
Great so where is the difference between using a unitary basis under GR. Normalization I fully recognize and relate to same goes for dimensionless values. Still doesn't address where dimensionless values isn't appropriate for specific relations. Oh Ive read your article its mannerism of writing is rather scattered but that's another issue so dont call me a liar on that. One of the reasons I had to reread it was I initially thought you declared the Gamna factor being the inverse of the beta function which would be incorrect but your B_y isn't identical to the normal beta function relation. Not that I saw you employing Gamma factor so it was irrelevant to mention. What Im suppose to be convinced by your graphic ? Simply because you employed dimensionless replacements or using normalized units ? Its fairly rudementary to normalize or make some relation dimensionless. Ive come across numerous articles that make \{8 \pi G \} normalized to one good example is the critical density formula nothing new or exciting about that. Do you not want to expand on your article for example The Kerr metric isn't a static solution. Perfect arena for testing your method on a rotating frame. You didn't really go into alot of detail in that section of your article. If you feel your article is a done deal then it amounts to just advertising in which case I lose all interest. Correct me if Im wrong but you assigned E_0 as invariant energy with M_0 being the invariant mass with E being total energy so explain why you have \{E=m_0\} and not \{E_0=m_0\} ? Correct me if Im wrong but your thread title does state testing. So add tests you haven't already done. Solving twin paradox with your methodology might prove a useful challenge as another example. However then you will have to deviate from the symmetry relations of constant velocity to include the rotations involved for acceleration

exploring DM as sterile neutrino's
In so far as a particle origin for DM it would be easier to apply the virial theorem to DM with regards to galaxy rotation curves the weakly interactive characteristics for example well suits neutrinos. Or any other particle that is weakly interactive. When you study the NFW profile which utilizes Virial theorem for galaxy rotation curves you find that its power law relations show that in order to obtain the measured galaxy rotation curves instead of the Keplar decline you need a greater amount of mass in fairly uniform distribution surrounding the galaxy. The DM halo distribution while being weakly interactive DM is still subject to gravity. One of the primary reasons its expected to drop out of thermal equilibrium early is that its also considered responsible for initializing mass density anistropy for early large scale structure formation. Obviously we cannot measure directly DM but we can certainly infer its existence in some form or another as a pressureless ( matter) component via the equations of state in cosmology. Some of these articles describe secondary effects that can be measured involving DM. Example below. The double beta decay in the above articles should also allow for some interactions that we can hopefully measure https://arxiv.org/pdf/1402.4119

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
If your going to attempt to do that then perhaps some consistency might be in order. Take for example your statement there is no momentum later on in your article yet your B_y which you describe as the inverse of the gamma factor includes velocity terms. Mass for example is resistance to inertia change. It is a kinematic property. You also claim no need for any geometry yet you discuss two manifolds S_1 and S_2. Which are geometric objects. Your use of a circle and sphere are both geometric objects. Now consider this any invariant quantity in physics does not rely on a metric one can arbitrarily choose any metric without changing the value of that invariant quantity. Ive read your paper several times over and I see no clear purpose or ontology view in its written format. However that's just my opinion. The inherent problem of ontology views trying to dictate how physics is done is that they often forget one of our primary jobs is to interpret datasets and graphs produced by experimental apparatus. You need geometry to accomplish that. Yes physics uses mathematics it is a fundamental tool for describing what we measure. Do not be fooled into thinking I believe in any fundamental realism I am well aware that terms such as mass, energy, fields, time etc Are abstract. Ive read countless ontology papers over the past 40 years. I am well aware of the difference between mathematical objects or descriptives vs fundamental realism. None of that changes the job of a physicist which requires those mathematics you dont feel important in order for that physicist to secure jobs etc. As far as that last link how did you program it without applying some form of geometry.. can you honestly state no geometry was used. I can readily accomplish the same using the standard methods with all those geometric relations. Do you honestly believe that simply because you can plot a 2d orbital that this encompasses all possible observer from other angles ? That was why I mentioned those little challenges. Lets see how well your mathematics work when you have multiple reference frames at any random 3d coordinate. Not just simply a simple case of a 2d plane. By the way you and I are both aware that link describes a Maximally symmetric spacetime. Lets see how well your calculations work without having a Maximally symmetric spacetime. ( Marcus Hanke already mentioned the relevant killing vectors). Im choosing to ignore the scalar quantity E as being in any regards a suitable replacement for spacetime geometry.

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
Read the forum rules material needs to presented here Im not about to go through a bunch of different links. This requirement has already been mentioned. I did the one exception by reading your main article. I will stick to that. From that main article I do not believe you can give the proper seperation distance between two inertial reference frames ds^2 without being able to curve trace the worldline between the two events. Particularly when the Lorentz transformations include not just time dilation but also length contractions. Try this without considering geometry try more than two events say 3 different reference frames and what each observer sees relative to each observer at 3 different coordinate locations. Then try it in a non Maximally symmetric spacetime such as one in rotation...ie Sagnac effect.

What's ridiculous is whenever I mention something in textbooks Im met with scorn. There is good reasons the stuff I mentioned exist in textbooks. Its a known methodology proven to work... For example you could take a constant accelerating twin and plot the curve after following the rextbook methodology and fully describe the curve by \{\frac{g^4€{c^2}\} which will return the hyperbolic geometry produced via a spacetime graph of the travelling twins worldline... I won't waste my time showing how that equation is the resultant see Lewis Ryders General relativity textbook

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
No thank you I don't visit forums to deal with attitude I read your paper that was enough for me. Take my opinion or not couldn't care one way or another Just reading through this thread its obvious your lacking in areas that others have pointed out as well. Of course you could have instead shown where your applying the vectors etc but you chose attitude instead of showing where my statement is in error. ( hint tangent vectors for slope curve fitting) commonly used for SR and GR... how is your methodology replacing them and giving the same detail ya know basic calculus curve fitting.... After all not all spacetimes are Maximally symmetric like Euclidean or Cartesian.

I must admit this is the first time Ive heard of this particular possibility. Thank you for bringing it up. Lol knowing me I will dig considerably deeper into related articles to get a better feel for the status of Strangeness as DM +1 They would certainly drop out of thermal equilibrium early enough to form DM seeding for large scale structure formation

exploring DM as sterile neutrino's
Lately I have been seeing numerous articles on right hand neutrinos contributing to dark matter. There are several different proposals. Those proposals involve whether or not neutrinos follow the terms of Dirac mass or Majorana mass https://arxiv.org/abs/2008.02110 here is a breakdown into singlets and doublets SU(2) \[{\small\begin{array}{|c|c|c|c|c|c|c|c|c|c|}\hline Field & \ell_L& \ell_R &v_L&U_L&d_L&U_R &D_R&\phi^+&\phi^0\\\hline T_3&- \frac{1}{2}&0&\frac{1}{2}&\frac{1}{2}&-\frac{1}{2}&0&0&\frac{1}{2}&-\frac{1}{2} \\\hline Y&-\frac{1}{2}&-1&-\frac{1}{2}&\frac{1}{6}&\frac{1}{6}& \frac{2}{3}&-\frac{1}{3}&\frac{1}{2}&\frac{1}{2}\\\hline Q&-1&-1&0&\frac{2}{3}&-\frac{1}{3}&\frac{2}{3}&-\frac{1}{3}&1&0\\\hline\end{array}}\] \(\psi_L\) doublet \[D_\mu\psi_L=[\partial_\mu-i\frac{g}{\sqrt{2}}(\tau^+W_\mu^+\tau^-W_\mu^-)-i\frac{g}{2}\tau^3W^3_\mu+i\acute{g}YB_\mu]\psi_L=\]\[\partial_\mu-i\frac{g}{\sqrt{2}}(\tau^+W_\mu^-)+ieQA_\mu-i\frac{g}{cos\theta_W}(\frac{t_3}{2}-Qsin^2\theta_W)Z_\mu]\psi_L\] \(\psi_R\) singlet \[D_\mu\psi_R=[\partial\mu+i\acute{g}YB_\mu]\psi_R=\partial_\mu+ieQA_\mu+i\frac{g}{cos\theta_W}Qsin^2\theta_WZ_\mu]\psi_W\] with \[\tau\pm=i\frac{\tau_1\pm\tau_2}{2}\] and charge operator defined as \[Q=\begin{pmatrix}\frac{1}{2}+Y&0\\0&-\frac{1}{2}+Y\end{pmatrix}\] \[e=g.sin\theta_W=g.cos\theta_W\] \[W_\mu\pm=\frac{W^1_\mu\pm iW_\mu^2}{\sqrt{2}}\] \[V_{ckm}=V^\dagger_{\mu L} V_{dL}\] The gauge group of electroweak interactions is \[SU(2)_L\otimes U(1)_Y\] where left handed quarks are in doublets of \[ SU(2)_L\] while right handed quarks are in singlets the electroweak interaction is given by the Langrangian \[\mathcal{L}=-\frac{1}{4}W^a_{\mu\nu}W^{\mu\nu}_a-\frac{1}{4}B_{\mu\nu}B^{\mu\nu}+\overline{\Psi}i\gamma_\mu D^\mu \Psi\] where \[W^{1,2,3},B_\mu\] are the four spin 1 boson fields associated to the generators of the gauge transformation \[\Psi\] The 3 generators of the \[SU(2)_L\] transformation are the three isospin operator components \[t^a=\frac{1}{2} \tau^a \] with \[\tau^a \] being the Pauli matrix and the generator of \[U(1)_\gamma\] being the weak hypercharge operator.

Below are some related articles involving DESI. The Kev range would readily fall under the mentioned warm dm models. However there is also papers that place right hand neutrinos being in the GeV range through double beta decay. DESI constraints https://www.osti.gov/servlets/purl/3011043 Has a particular section to follow up on massive neutrinos behaving as dark matter described in above link. https://arxiv.org/abs/2507.01380 double beta decay primer https://arxiv.org/abs/2108.09364 In a nutshell the possibility is there so I started this thread to explore various examinations and starting a discussion on the the pros and cons of such a proposal. Naturally I would be interested in any related papers including counter arguments. This is not my own model proposal but a discussion on models presented by others. It doesn't suit a mainstream forum not yet anyways lol. As for myself I see the potential but I question whether or not the mass terms will meet the required DM mass distribution. There was a fairly recent study that placed constraints on any simple Dirac mass term for right hand neutrinos in that examinations of the energy sector did not have any relevant findings. Still digging up that study hopefully I can find it however if I recall it constrained 5 KeV or less if memory serves. other related papers https://arxiv.org/pdf/1911.05092.pdf https://arxiv.org/pdf/1901.00151.pdf https://arxiv.org/pdf/2109.00767v2.pdf https://arxiv.org/abs/1402.2301 https://arxiv.org/pdf/0708.1033 Located the light neutrino constraint paper via MicroBoone https://arxiv.org/abs/2512.07159

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
Well having gone through this thread as well as the OPs main paper. I dont see any practicality behind this. No vector fields, no spinor relations, Redefining standard physics terminology to suit the OP ( energy as primary example) Use of geometry relations without defining any geometry. Trying to replace GR without actually understanding GR.... Trying to apply energy to geometry when spacetime by itself has no energy. ( it's simply a mathematical object) a mathematical construct. A field is also a mathematical construct. It is the SM particles that reside in spacetime and how they interact with one another that tells spacetime how to curve. So having an energy equivalence to the invariant mass only fills the \{T^{00}\} component of the stress energy momentum tensor. Leaving all other components of that stress energy momentum tensor unfulfilled. As the OP doesn't understand GR its useless pointing that out. How the OP plans on dealing with stress and shear components of a multiparticle field without use of any geometry is something I find utterly impractical. I may have missed this but I also didn't see any treatments of how angular momentum factors in let alone linear and angular force... something which GR fully describes. After all physics includes the study of forces. And force is a vector quantity right along with acceleration which is both change in speed and direction Ola another vector

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
My response has nothing to do with memorization from a textbook. The definition for energy has been the sane for well over 5 centuries. Perhaps you should study a classical physics textbook and see how energy ties into the work equations then learn how it ties into the kinematic equations under GR and SR Those definitions are used in all physics regardless of any ontology. Unlike yourself I do not rely on AI Do you even consider anywhere in your article the inner product of vectors or the outer product or the cross product of vectors which is incorporated into the tensors your trying to replace? Nor have I seen anything regarding bilinear forms needed for curvature I certainly haven't seen anything related to parametric equations which GR incorporates Looking through your article you completely ignored all symmetry relations with regards to first order, second order and higher relations. Specifically the symmetry relations with regards to freefall velocity (first order terms) used with conservation of energy momentum. I didn't see much in regards to acceleration (second order terms) Nor does your normalization of energy to invariant mass have much practicality when it comes to distinguishing potential energy and kinetic energy when applying the four momentum. good luck with your article. As I read it and can honestly say it will never get far as it is written. Is the circle the only curvature form you have examined ? Ie just positive curvature? How do you plan to deal with energy measured being relative to the observer when you normalized energy to invariant mass ? Your article deals primarily with first order scalar quantities not very practical when you require vector fields including higher order time differentials perhaps that's something you look into

Simplifying SR and GR with Relational Geometry — Algebraic Derivations Without Tensors. Testing and discussion.
Why dont we start with some very basic classical physics definitions which apparently you never learned. Space is volume, spacetime is a geometry that uses the Interval (ct) to give Time dimensionality of length. Energy is the ability of a system/ state etc to perform work. Spacetime does not equal energy by any mainstream physics application. The above definitions apply to all main stream physics theories if your not following the above definitions then this thread definitely belongs in Speculations. Particularly how those tensor entries apply to the Kronecker delta and Levi-Civitta connections.

It could also be argued there is no hard and fast truth in science. There is truth to the best of current understanding. Good example that everyone is familiar with in physics is Newtons laws of inertia. Everyone firmly believed the equations applied regardless of the measured objects inertia. Later findings showed its only valid for non relativistic inertia hence GR. I also wonder why this thread is in politics.
