Gravitational Fluctuations as an Alternative to Inflation
Universe, 2019 The ability to reproduce the observed matter power spectrum P ( k ) to high accuracy is often considered as a triumph of inflation. In this work, we explore an alternative explanation for the power spectrum based on nonperturbative quantum field ...

Bounce Loop Quantum Cosmology Corrected Gauss-Bonnet Gravity
, 2015 We develop a Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified $F(\mathcal{G})$ theories of gravity.

Geophysical Impacts and Spectroscopic Identification of a Hydrous Iron Sulfate on Icy Worlds
Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Over geologic time‐scales, large volumes of exogenic sulfur ions from Io's plasma torus have been supplied to the surface of Europa and Ganymede, which, combined with recent interpretations of orbiter images, dynamical modeling, and surface‐subsurface exchange, suggests further sulfur transport into the interior of the icy worlds.

, 2012 I review two cosmological paradigms which are alternative to the current inflationary scenario. The first alternative is the "matter bounce", a non-singular bouncing cosmology with a matter-dominated phase of contraction.

Hybrid Deference, Hybrid Chance
Philosophy and Phenomenological Research, Volume 112, Issue 1, Page 214-233, January 2026.ABSTRACT If you learn about one kind of chance and nothing else, then you should defer to those chances. But what if you learn about more than one kind of chance? In such “hybrid” cases, familiar chance‐credence principles, like the Principal Principle, go silent when they should intuitively speak.

A DISCOURSE ANALYSIS THROUGH CORPUS LINGUISTICS ON THE CASE OF POPULAR SCIENCE BOOK THE GRAND DESIGN
Kajian Linguistik dan Sastra, 2016 This study aims to discover the theme of popular physics book, The Grand Design, through corpus linguistics and discourse analysis as well as how the authors of the book describe the field of study which in fact is not their main focus to work on.

Quantum Potential Approach to Quantum Cosmology [PDF]
, 1995 In this paper we discuss the quantum potential approach of Bohm in the context of quantum cosmological model. This approach makes it possible to convert the wavefunction of the universe to a set of equations describing the time evolution of the universe.

Advances in Astronomy, Volume 2026, Issue 1, 2026.We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Cosmology from quantum potential
Physics Letters B, 2015 It was shown recently that replacing classical geodesics with quantal (Bohmian) trajectories gives rise to a quantum corrected Raychaudhuri equation (QRE).
