A critical note on time in the multiverse [PDF]
, 2013 In recent analyses of standard, single-universe, cosmology, it was pointed out that specific assumptions regarding the distribution and motion of matter must be made in order to set up the cosmological standard model with a global time parameter. Relying

Noncommutativity in Effective Loop Quantum Cosmology
Advances in High Energy Physics, 2019 We construct a noncommutative extension of the Loop Quantum Cosmology effective scheme for the flat FLRW model with a free scalar field via a theta deformation.

A proposal for a Bohmian ontology of quantum gravity [PDF]
, 2013 The paper shows how the Bohmian approach to quantum physics can be applied to develop a clear and coherent ontology of non-perturbative quantum gravity.

Qubit Clock in Quantum Cosmology
, 2022 We investigate the emergent time scenario in quantum cosmology based on the Page–Wotters approach. Using a quantum cosmological model with a qubit clock, it is demonstrated how the entanglement between the qubit clock and the geometry derives ...

Spatial Statistics for Screening Molecular Structures
Small, EarlyView.Deep architectures for materials discovery demand vast training data and obscure the structure‐property link. This review shows how spatial statistics offer a physically grounded alternative: voxelized fields and two‐point correlations, compressed by principal component analysis, yield convex, interpretable descriptors. Lean surrogates then reach sub‐2%

Theism and Physical Cosmology [PDF]
, 2010 Physical cosmology purports to establish precise and testable claims about the origin of the universe. Thus, cosmology bears directly on traditional metaphysical claims -- in particular, claims about whether the universe has a creator (i.e. God).

Polymer Dynamics of Isotropic Universe in Ashtekar and in Volume Variables
Universe, 2022 We analyze the semiclassical and quantum polymer dynamics of the isotropic Universe in terms of both the standard Ashtekar-Barbero-Immirzi connection and its conjugate momentum and also of the new generalized coordinate conjugate to the Universe volume ...

Kant on Rational Reference: Theology as transcendental philosophy
European Journal of Philosophy, EarlyView.Abstract The Critical Kant famously held that our cognition requires intuition, or essentially singular representation. Kant is also often understood as taking a dismissive attitude toward his rationalist predecessors' accounts of how we cognize singulars or individuals.

The Structure and Interpretation of Cosmology [PDF]
, 2003 The purpose of this paper is to review, clarify, and critically analyse modern mathematical cosmology. The emphasis is upon the mathematical structures involved, rather than numerical computations.
