Inflation in a Non-Commutative Riemannian-Foliated Quantum Gravity Domain
We explore the implications of Branch-Cut Quantum Gravity (BCQG), a novel framework leveraging non-commutative geometry within a symplectic phase-space, on the accelerated expansion of the universe. Non-commutativity, introduced through a deformation of the Poisson algebra and enhanced by a symplectic metric, provides a robust mechanism for addressing key challenges in cosmology, such as the youngness paradox and the fine-tuning of initial conditions in standard inflationary models. By embedding quantum dual-field dynamics within a Riemannian-foliated spacetime, BCQG naturally integrates short- and long-range spacetime effects into a unified formalism. This approach offers an alternative to standard inflationary models by predicting cosmic acceleration through geometric restructuring rather than finely-tuned initial states. In contrast to models like ΛCDM or String Theory, BCQG introduces unique corrections to cosmic scale factors and predicts a novel transition between contraction and expansion phases via topological branch-cuts, circumventing the singularity problem. Moreover, BCQG's non-commutative formulation provides testable predictions, such as modifications in cosmic microwave background (CMB) anisotropies and large-scale structure evolution. We discuss the mathematical foundation, observational implications, and future avenues for validating BCQG through astrophysical data, positioning it as a promising theoretical alternative for understanding the universe's accelerated growth.
期刊介绍:
Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
