The first experimental paper by BESIII collaboration (motivated under new mirror oscillation model) has just been published: Search for invisible decays of the Λ baryon. It was the first direct test of my idea on neutral hadron oscillations. It gives an upper limit of the invisible decay branching fraction for the Λ baryon: <7.4×10^{−5} , which is consistent with my model. Unfortunately, it is not sensitive enough yet to reach the level of my prediction in the new model: 4.4×10^{−7}. I hope that more experimental works will be coming on invisible decays of other hadrons like K^{0}_{L} and K^{0}_{S}. I wish that people in the business of neutron lifetime measurements could have done much more convincing tests earlier.

## A crackpot’s counter-statement

Some physicists have labeled me as a crack pot when considering my works on the new theoretical framework of mirror matter theory. However, I disagree in the spirit of scientific principles. With three papers published in esteemed journals, seven invited seminars by unrelated people (or more than 10 in total), and grant-seeking in collaboration with several different groups, I don’t think that it is fair to categorize my work on this topic as crackpottery. It is not, especially when considering the unique concrete predictions from my new model that can be readily tested in the laboratory using existing technologies.

## Future of the new mirror matter theory

The new mirror matter theory has only a very rough framework with many of its aspects waiting to be greatly improved and further developed as a nascent research direction. In particular, its mathematical rigor and foundations have yet to be established. Relevant new mathematical tools and approaches are desired to be implemented in the new theory. Theoretical efforts in the past several decades on fundamental physics, especially on topological quantum field theory, string theory, and quantum gravity, need to be merged into the new theoretical framework under the guidance of the newly proposed first principles. Most importantly, the neutral hadron oscillation effects predicted by the new theory are ready to be experimentally tested in laboratory, and it is time for more observation and simulation works in astronomy and cosmology under the consideration of the new theory to be conducted.

As presented below, I’d like to say a few words on the future direction of the new theory to interested mathematicians and physicists.

I just tried to post my new paper of “First Principles of Consistent Physics” on arXiv.org. Unfortunately it was put on hold immediately and I then submitted it to the OSF eprint server. This is quite an exciting paper to me. It proposes new foundations and guiding principles on fundamental physics and cosmology based and improved upon my early blog “first principles of physics“. It should shed new light on further developments of the new mirror framework.

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:

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

## How should private foundations support science?

It is amazing that there exist quite some private foundations in the United States who care about science and are enthusiastic about funding scientific projects. However, a lot of them, if not all, don’t seem to know how they should support science in a complementary way when compared to government funding agencies like NSF and DoE.

## Time to reform peer-review

One of the critical features in scientific research is the application of the so-called peer-review process before a scientific paper is officially published in a journal. Ideally, peer-review, at least seemingly in its original purpose, should serve as a measure of quality control that benefits both the authors and the readers. However, nowadays, it becomes more and more like an obstruction to the advancement of science, in particular, in terms of radically new ideas and directions.

In a nostalgic review article titled “Twenty years of the Weyl anomaly” [Michael J Duff, Class. Quantum Grav. 11, 1387 (1994)], Duff recalled the history of his discovery of the Weyl or conformal anomaly in quantum theory with Derek Capper.

## 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.
