, 2006 Brane-world models, where observers are restricted to a brane in a higher-dimensional spacetime, offer a novel perspective on cosmology. I discuss some approaches to cosmology in extra dimensions and some interesting aspects of gravity and cosmology in ...

DECOHERENCE IN QUANTUM COSMOLOGY AND THE COSMOLOGICAL CONSTANT [PDF]
Modern Physics Letters A, 2013 We discuss a spacetime having the topology of S3×ℝ but with a different smoothness structure. The initial state of the cosmos in our model is identified with a wildly embedded 3-sphere (or a fractal space). In previous work we showed that a wild embedding is obtained by a quantization of a usual (or tame) embedding.

Testing loop quantum cosmology [PDF]
, 2017 Loop quantum cosmology predicts that quantum gravity effects resolve the big-bang singularity and replace it by a cosmic bounce. Furthermore, loop quantum cosmology can also modify the form of primordial cosmological perturbations, for example by ...

Emergent cosmology from matrix theory
Journal of High Energy Physics, 2022 Matrix theory is a proposed non-perturbative definition of superstring theory in which space is emergent. We begin a study of cosmology in the context of matrix theory.

From Reductionism to Contextualism: L. Wittgenstein and the Dimensions of Modern Cosmology [PDF]
Философия и космологияThis article offers a consideration of potential ways to apply the methodology of the philosophy of everyday language to solve modern problems of cosmology and the philosophy of cosmology. Modern cosmology emerges as an independent scientific discipline,

Precision cosmology, Accuracy cosmology and Statistical cosmology [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractThe avalanche of data over the past 10-20 years has propelled cosmology into the “precision era”. The next challenge cosmology has to meet is to enter the era of accuracy. Because of the intrinsic nature of studying the Cosmos and the sheer amount of data available now and coming soon, the only way to meet this challenge is by developing ...

When misinterpreting the Bible becomes a habit
HTS Teologiese Studies/Theological Studies, 2018 Ancient Near Eastern (ANE) texts should be interpreted against the background of the magico-mythical cosmology of their time, and the Bible is no exception.

Evolution of cosmological horizons of wormhole cosmology [PDF]
International Journal of Modern Physics D, 2020 Recently, we solved Einstein’s field equations to obtain the exact solution of the cosmological model with the Morris–Thorne-type wormhole. We found the apparent horizons and analyzed their geometric natures, including the causal structures. We also derived the Hawking temperature near the apparent cosmological horizon.
