OSMU 2024 Talk 8 by Siddhant Das, 21st June 2024

School: Arnold Sommerfeld Center, LMU Munich
Title: Quantum arrival-time and Bohmian trajectories
Abstract: Computing the probability density of arrival, detection or flight times of a quantum particle at a detector, which is empirically well-accessible, is one of the last areas where physicists disagree about what QM should predict. Over the years, many disparate proposals have been put forward to address this problem. I will quickly examine some of the key suggestions and make the case that a Bohmian trajectory-based method is the most compelling, broadly applicable, and well-supported by existing experimental data, e.g., momentum and scattering stati...

    Neutron decay cosmology. A homeostatic universe maintained by the reciprocal processes of electron capture at event horizons and free neutron decay in deep voids. Gravity gathers mass to event horizons. All matter is made neutrons at event horizons because of electron capture. Neutrons drop kinetic energy off as mass for event horizon Neutron takes an EinsteinRosen bridge from highest energy pressure conditions to lowest energy density point of space where the quantum basement is lowest and easiest to penetrate. Neutron out in deep void Decays into amorphous monatomic hydrogen, proton electron soup, Dark matter. The decay from neutron 0.6fm⁴ to 1m³ of hydrogen gas is a volume increase of 10⁴⁵. Expansion. Dark energy. In time this amorphous hydrogen stabilizes and coalesces and tasks towards event horizons. Neutron decay cosmology is inevitable. No new particles. Respect for the Dark matter which exists curving space to cause cosmological red shift.

    phoronomy Term used by Kant in the Metaphysical Foundations of Natural Science (1786) for the study of the motions of bodies, without regard to forces or the nature of the bodies themselves: kinematics. Leibniz invented the word in the 1680s to denote the doctrine of the “laws of nature,” whereby he meant the dynamical principles of collision theory.

    If you are going to get rid of the quantum gravity renormalization problem by adding those 36 fields that have no particles, I assume you have to make some assumptions about how those fields interact with the Standard Model fields. Isn't that a significant addition to the Standard Model? I don't understand how to judge simplicity of a model so I can't tell if that is better than, say, string theory with whatever number of dimensions and topology required to make things work. Oppenheim's post-quantum gravity approach doesn't add new particles or dimensions AFAICT but the equations are complex enough to need new tricks to fit on a page that I haven't seen before. It is an objective collapse scheme. Does your story have wave functions objectively collapsing? If not, what do you think should be done about the measurement problem?

    just modify the roots of one however you like, quaternions that serve as the gamma matrices for the dirac equation for example just needs a root of one that squares to positive one but multiplies different in different orders when multiplied by roots of -1.

  • @monkerud2108

    the issue is that minkowsky space for Lorentz invariant physics is just identical to euclidian space with a different basis for transformations. a sort of pretend version that works because the physics is Lorentz invariant, it looks like it is different because people don't understand coordinate systems very well. if you never change coordinate systems the two are identical as long as the physics in euclidian space has a notion of physical time dilation and length contraction. people get stuck up on time being the same for everyone, rather than time being a physical cycle of some system, and so the difference seems to be something about the space, when it has nothing to do with the metric of the space at all, only what metric allows you to be lazy in describing the physical systems in it.

  • @monkerud2108
    @monkerud2108 6 месяцев назад

    didn't say anything about qft yet, but essentially qft has to be somewhat modified anyway and it only really makes sense to do that with respect to the gravitational physics, and there vacuum currents that decide what constitutes a preferred direction in any given situation.

  • @monkerud2108
    @monkerud2108 6 месяцев назад

    the thing to appreciate at the foundations, with no real content to the physics, is that if you break Lorentz symmetry slightly you kind of need a preferred reference frame to make sense of it, and so minkowsky spacetime makes less sense in that case than euclidian. a preferred direction without breaking the symmetry is just an artifact in a sense. when it comes to gravitational physics the notion of a preferred background becomes more important, because there is a concrete difference between moving through space and a scalar speed of light relative to other places, so the geometry is not quite the same if you treat the two as equivalent in euclidian space, they are almost the same, but not quite. it is different with respect to gravitational potentials and time dilation with or without length contraction, once your preferred direction is a direction of relative motion with respect to vacuum structure, then you are pretty much forced into a certain background vacuum current, the gradient energy in gr is not the same as the energy involved in the current, not exactly so it is a complicated picture. but in the end the notion of a preffered direction based on local rest frames with respect to the vacuum is necessary, but it is not the same in all cases, not all inertial frames are the same a rest frame with respect to the vacuum current is not the same as free fall, because you can start at 0 velocity at any height, and then you start with a definite current and so on. this is not so simple, but at the end of the day it is alright, it is the right way to go to make progress in unification in my opinion.

    Interpolate between any discrete symmetries/transforms, there is the continuous. Nature does not care about simplicity. Simplicity is no law of nature. Note, quantum mechanics is _more continuous_ than classical mechanics, not less --- we can prepare a system in superpositions smoothly from pure states to pure states. Can't do that in classical mechanics.

      The Grassmann envelope of E8(-24) was introduced for the first time, leading to a new supersymmetry algebra. This new structure was used to explore the subgroup analogous to SU(3,2) x SU(5), which led to a new approach for studying three generations of matter with only 128 degrees of freedom instead of 192. The action for a complete gauge theory with GUT and gravity was articulated at the end of the talk. I'm not sure how this is conjecture or rambling about opinions, but I appreciate you sharing your opinion.

    Great conversation. There will be a big surprise for everyone soon. Base Twelve Mathematics - surprisingly - will save the day in terms of revealing a geometry which is currently not available to us in base ten. The geometry of the Universe is in base twelve and gives rise to a type of geometry which is able to accommodate the empty space inside of everything, and the base twelve version of Pi which emerges from this geometry has different characteristics from what we think Pi is. It gives rise to a geometric structure within the circumference of the circle which eventually solves the problem of infinity by giving structure to the smallest of the small, as well as access to the environment in which it resides. It will open up many avenues for exploration, and eventually lead us through the journey from quantum to the stars.
