The Radionactive Universe
In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosm...
متن کاملThe Qur’an and Mysticism On The Universe of Two Sides
The universe has an exterior known as the material world and an interior called the “hereafter.” So are the Qur’an and mankind. In other words, the universe, mankind and the Qur’an have hierarchical stages. The universe and mankind comprise the physical world, but the Qur’an constitutes the Divine Law. Since the origin of all three is one single source, one can say the former matches t...
متن کاملThe Anamorphic Universe the Anamorphic Universe
We introduce “anamorphic” cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant ...
متن کاملNoether Symmetry in f(T) Theory at the anisotropic universe
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...
متن کاملThe Quantum Universe
On the basis that the universe is a closed quantum system with no external observers, we propose a paradigm in which the universe jumps through a series of stages. Each stage is defined by a quantum state, an information content, and rules governing temporal evolution. Only some of these rules are currently understood; we can calculate answers to quantum questions, but we do not know why those ...
