“…( 19) shows a very intriguing feature: in order to conserve the entropy, the central charge c = g has to increase linearly with the space dimension number n. This indicates that three generations of quantum particles in 4-d spacetime may be tied to the three space dimensions they reside in. To apply it to the dynamic evolution of the universe [31,32], we need to consider that global and gauge symmetries can reduce the eective volume or surface area. Therefore, n should be replaced with the dimension n(T ) of unbroken gauge groups and the factor m(T ) = 2 when the mirror symmetry is unbroken for the entropy of the universe,…”

New physics and models for the most compact astronomical objects - neutron / quark stars and black holes are proposed. Under the new supersymmetric mirror models, neutron stars at least heavy ones could be born from hot deconfined quark matter in the core with a mass limit less than $2.5 M_\odot$. Even heavier cores will inevitably collapse into black holes as quark matter with more deconfined quark flavors becomes ever softer during the staged restoration of flavor symmetry. With new understanding of gravity as mean field theories emergent from the underlying quantum theories for providing the smooth background spacetime geometry for quantum particles, the black hole interior can be described well as a perfect fluid of free massless Majorana fermions and gauge bosons under the new genuine 2-d model. In particular, the conformal invariance on a 2-d torus for the black hole gives rise to desired consistent results for the interior microphysics and structures including its temperature, density, and entropy. Conjectures for further studies of the black hole and the early universe are also discussed in the new framework.

“…To be concise, Principle-1 provides the conceptual and math formalism, Principle-2 sets the physical constraints and symmetries, and Principle-3 determines the physical contents (particle fields and interactions). Based on these three first principles, the new mirror theoretical framework [5,6] can be described by a series of Supersymmetric Mirror Models (SMM1 for 1-d time, SMM2 for 2-d spacetime, and SMM4 for 4-d spacetime) for different spacetime phases and corresponding symmetry breaking models of SMM1b, SMM2b, and SMM4b for the dynamics between these phases. Meanwhile, gravity can be understood as an emergent classical phenomenon of smooth spacetime geometry [7].…”

For a consistent picture of fundamental physics and cosmology, three first principles are proposed as the foundations. That is, quantum variational principle that provides the formalism, consistent observation principle that set physical constraints and symmetries, and spacetime inflation principle that determines physical contents (particle fields and interactions). Under these three principles, a series of supersymmetric mirror models are constructed to study various phases of the universe at different spacetime dimensions and the dynamics between the phases. In particular, mirror symmetry, as the orientation symmetry of the underlying geometry, plays a critical role in the new framework.

“…The idea of the existence of fundamental laws of physics is based on the principles of causality. Nevertheless, this principle collides with the problems of the physics of the micro-world (Tan, 2020). The nature of these problems is primarily related to the Geizenberg uncertainty principle, according to which it is impossible to accurately determine the states of microparticles.…”

The question of constructing an evolutionary picture of the world based on the results obtained by extending classical mechanics is considered. The expansion of mechanics arose as a result of taking into account the role of the structure of bodies in their dynamics. It is shown that such an extension leads to the possibility of combining branches of physics, in particular, to the substantiation of the laws of thermodynamics, statistical physics, kinetics within the framework of the laws of classical mechanics. It turned out that, according to the laws of classical mechanics, matter is infinitely divisible and can be represented by an infinite hierarchical structure from simple to complex. The expansion showed the existence of universal principles connecting the laws of the upper rung of the hierarchical ladder of matter with the laws of the lower rung. It is considered how they lead to the possibility of constructing a picture of the world based on the fundamental laws of nature.
