Joigus' proposition is mathematically sound and intriguing. I had not heard of it before so +1 for bringing it to my attention. Very similar arguments (the fact that you can add an arbitrary 4-momentum to a physical 4-momentum without changing its on-shell character) appears in theorems in QFT like, Soft boson theorems (soft pion theorems first historical argument) Ward-Takahashi identities Definition of Feynman's propagator: integral extended to all momenta, including off-shell: https://en.wikipedia.org/wiki/Propagator#Scalar_propagator Take a look at this scalar propagator. It's an integral to the whole momentum space. Edit: More info for you, @studiot. Off-shell amplitudes in the propagator have to do with internal legs in Feynman diagrams. The amplitude for a particle to be created at one point and annihilated at another. The soft-boson idea is to do with low-energy (virtual) bosons that escape to infinity (external legs in Feynman diagrams). Another bundle of key words for it is "infrared divergences". When you calculate the cross section in, e.g., QED, even after you renormalise charge, mass, etc., it still has infinities due to arbitrarily low-energy ("soft") photons going off in all directions. You must do a cut off to remove those photons you will never detect on account of your detectors having an effective energy threshold (they can't detect arbitrarily "soft" photons escaping to infinity).

We probably can't have tens of thousands of theories, but we can certainly have more than one. We have two theories of gravity (Newtonian and GR). Both have their place. We have two theories related to electromagnetism (classical waves and quantum theory). Both have their place.

What are the error bars on the Silvertooth experiment? 3 hours ago, lidal said: SRT also has no extraordinary internal consistency. I had the Twin Paradox in mind. With regard to QM I said: “ The case of QM is a little different”. I had in mind the fact that I know of no experiment that extraordinarily proves or disproves QM. Neither was I referring to any extraordinary internal consistency/inconsistency of QM. All I was saying was that my new theory is much more explanatory than QM, for example on the “ Which Way” and quantum erasure experiment. Ultimately SR is math, and if you can show that algebra isn’t internally consistent, you could make some real noise. 3 hours ago, lidal said: CMBR disproves relativity indirectly because it agrees with the Silvertooth experiment. You can’t legitimately claim anything agrees with an experiment that was not properly executed. (specifically those error bars) 3 hours ago, lidal said: It was published in Nature journal as an advertisement. So, not published in the scientific meaning of the word

The answer to the this question has been given already in this thread. In no way does quantum phenomena point to a god or anything supernatural. Your idea is a belief, which quite different than a theory.

With regard to quantum phenomena, my theory does not provide a new model, it is a new scientific paradigm. Let me put it this way. QM is correct as a model, at least with regard to the double-slit experiments, including Which-Way and quantum erasure. The problem with QM is that it is counter-intuitive. The new theory provides intuitive understanding to QM. So, you asked me my model: it is QM itself, for now. But don't think that this is all.

That addendum (God did it) makes it dogma, and removes it from the realm of science.
Polykephalous Posted July 25, 2020 Posted July 25, 2020 How about if God created nature for the benefit and pleasure of mankind, a garden of Eden perhaps. By the way, I am totally not religious.

Many scientists in the past, feeling very uncomfortable about making statements that denied god, chose to phrase the question as, Why did god choose to make the world like this? One answer for every question "God did it" is clearly not good enough. Edited July 26, 2020 by joigus

The intervention of God in classical phenomena is not as obvious as in quantum phenomena. This is because we use concepts such as 'field' to explain, for example, electrostatic force. It was after I understood quantum phenomena in terms of God's intervention that I realized that God is behind all laws of physics, including classical phenomena. Yes, God pushes two charges apart precisely according to Coloumb's law. What is the agent that executes Coulomb's laws ? The laws of physics are like human rules and laws that are written down on paper. Those human rules and laws need someone to execute them. Who executes the laws of physics ? How do the charges know the distance between them ? Are they intelligent enough to calculate the force according to Coulomb's law ? Has any one ever made sense of what 'fields' are ? Imagine dropping a stone on a pond. Who solves the differential equations that determine the wave? The watermolecules themselves? The space between them ? God solves the differential equations in real time and move the molecules. So don't throw a stone on a pond for no reason because you are occupying His computational power. But don't worry, He has infinite power. -2
