First principles of physics

The approach of first principles has been pursued in the development and history of physics. Ever since the establishment of the Standard Model of particle physics in 1970s, the idea of going after theory of everything has become popular as the latest approach of first principles among theoretical physicists for unifying all particles and interactions. However, we seem to live in a dynamic world as indicated, e.g., since the discovery of an expanding Universe and it is definitely at odds with the static picture of an ultimate unified theory for physics.

The dynamic picture tells us that the time reversal symmetry has to be broken and it has to be the first (broken) symmetry. Whatever first principles we propose have to be able to naturally break this symmetry first in the very beginning. And there is no reason why the current 4-dimensional spacetime, in particular, its dimensions can’t be dynamic. It is probably more natural to consider that spacetime has evolved in a dimension-by-dimension way.

First of all, we propose and summarize the three first principles as follows:

  1. A measurable finite physical world is assumed.
  2. The quantum version of the variation principle in terms of Feynman’s path integral formalism is applied.
  3. Spacetime emerges via dimensional phase transitions (i.e., first time dimension and then space dimensions got inflated).

Old Wine in New Bottles – How does science advance?

A lot of times science advances by incorporating or interpreting old ideas under new scenarios.

For example, Lorentz first proposed the so-called Lorentz transformation, but it was Einstein who correctly interpreted and applied it in his theory of special relativity. Yang and Mills first came up with the SU(2) gauge theory idea for studying nuclear isospin. But it was Glashow, Weinberg, Salam , and ‘t Hooft who found the best application of the idea to the electroweak interaction eventually leading to the most celebrated unification theory (called the Standard Model) for all three gauge interactions of the known elementary particles.

Does the Universe Have a Mirror Sector?

[This is a repost of the popular introduction page on the new mirror matter theory]

Modern physics is pillared by Einstein’s theory of general relativity (that defines spacetime and the gravitational force) and the Standard Model as the best known quantum theory (that governs quantum particles and the other known interactions). Despite tremendous successes of the two theories and decades of more scientific efforts, there remains a wide range of puzzling phenomena in fundamental physics and the dream of unification of general relativity and quantum theory has never come true.

Invisible decays and equivalence of CP violation and mirror symmetry breaking scales

COVID-19 pandemic has hindered my scientific production quite a bit. But finally my new paper on “invisible decays of neutral hadrons” is finished though it should have been done months ago. It provides precise predictions on invisible decay branching fractions of long-lived neutral hadrons that can be readily measured at existing collider facilities. The idea is that CP violation can be considered as a direct result of spontaneous mirror symmetry breaking at staged quark condensation (e.g., at temperatures of 100GeV – 100 MeV in the early Universe). For a neutral kaon system, it means that the CP and mirror breaking scales, i.e., the mixing strength and mass splitting parameters should be the same.

How risky or controversial is my work on mirror matter theory?

To demonstrate the risky or controversial aspects of my work on mirror matter theory, I’d like to share more comments extracted from various review reports from the expert physicists when refereeing my work. See here for early comments on my work. Clearly, the controversies are getting escalated on my new work on a dynamical view of the Universe as even relatively open-mined arXiv decided to deny my submission (see here). The list of the following review comments is sort of in the order from positive to negative.

  • Example 1:

This subject is a hot topic, and the results are very interesting in light of future experimental measurements for the light quark sector.

No theory of everything

Here is my new paper that provides a dynamic view on theory of everything. Normally arXiv should have it posted online on Feb. 4 but instead has put it on hold for nearly two weeks. So I have to submit it as an OSF preprint and to the archive of “crackpottery”[viXra:2002.0262] since arXiv is probably considering the paper a crackpot. It can also be downloaded from this page with all my papers on mirror matter theory (A persistent link of my mirror papers is also on the side menu). Below is the popular summary of this paper:

No single unification theory of everything. The universe is dynamic and so are the underlying physical models and spacetime. As our 4-d spacetime evolves dimension by dimension in the early universe, consistent yet different models emerge one by one with different sets of particles and interactions. A new set of first principles are proposed for building such models with new understanding of supersymmetry, mirror symmetry, and the dynamic mechanism – spontaneous symmetry breaking. Under this framework, the arrow of time is naturally explained and the Standard Model of physics is elegantly extended to time zero of the universe.

New physics of mirror matter manifests in a topological way

Modern physicists are used to a perturbative way to solve or understand problems in modern physics. In particular, since the invention of the powerful Feynman diagram technique by Richard Feynman, particle physicists are so fond of this perturbation tool and can seldom talk about physics without showing some Feynman diagrams.

However, there indeed exist some fundamental physical processes that can not be described by Feynman diagrams. These processes are typically called nonperturbative or topological transitions that have been studied since the discovery of “instanton” about half a century ago.

Unfortunately, perturbation theory is planted in the minds of a lot of particle physicists so firmly that they could not think in other possible topological ways. This has to be part of the reasons why some editors and reviewers have been so easy to dismiss my works. It may also be causing other physicists jumping on and off the bandwagon of my theory.

Most influential works and physicists on my mirror-matter theory

The first Christmas or Christian New Year has just arrived and the solar New Year Day of 2020 is coming since I posted my first paper on mirror matter theory on the Chinese New Year day (spring festival) of 2019. I’d like to take this moment to acknowledge some scientists and their works that have been the most influential during my studies on mirror matter theory. It is definitely from a personal perspective and far from a complete list. I apologize if some important works are omitted.

Scientists:

Tsung-Dao Lee (李政道) and Chen-Ning Yang (杨振宁) shared the 1957 Nobel Prize on their parity violation work [T. D. Lee and C. N. Yang, Phys. Rev. 104, 254 (1956)], which also opened the door to the studies of mirror symmetry.

Edward W. Kolb is a great cosmologist and his early work on mirror matter has fully turned my attention to mirror matter theory. The beautiful picture about mirror-matter in the early Universe is strikingly presented in his Nature paper [E. W. Kolb, D. Seckel, and M. S. Turner, Nature 314, 415 (1985)]; I leaned a lot from his classic textbook “the early universe” with M.S. Turner.

Corrections to recent media coverage on the mirror matter theory

One piece of news regarding mirror matter studies was published in June, this year by New Scientist as a cover story titled “We’ve seen signs of a mirror-image universe that is touching our own”. I was interviewed and also quoted in this article. But I was not informed that the article was actually centered about Leah Broussard’s experiment at Oak Ridge national laboratory. As a matter of fact, I was not aware of it at all. The ironic part is that her experiment, as far as I understand, will not uncover any new physics if my new model is correct while I was quoted in the article like a theorist endorsing this and other similar experiments.

I was not aware of this article until one of my Chinese friends showed me the Chinese version of the article. Then I read the full English version from my institution’s library (the online version is not free). The article could have been a good one had the author replaced the experiments with, or at least focused on the ones discussed in the APS april meeting this year. Here are the links to the talks on neutron lifetime experiments at the meeting: session C14 and session D14. I wish I could have attended that meeting.

Converting dark matter search programs to mirror matter studies

In light of the newly developed model (M3 and SM3 ), if further confirmed, most effort of current dark matter search will be destined to failures. Indeed, there is nothing to detect if there is no direct interaction, however weak, between normal particles and dark (mirror) particles. This makes all the Weakly-Interacting-Massive-Particle-like (WIMP-like) or axion search programs to no avail. However, the advancement of the detection technology with the past efforts including those for the detection of neutrinos could be rekindled to a new life for the studies of mirror matter.
