Weighing the Universe.

The 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...

Noether 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...

Weighing the universe with the cosmic microwave background.

Variations in V, the total density of the Universe, leave an imprint on the power spectrum of temperature fluctuations in the cosmic microwave background (CMB). We evaluate the precision with which V can be determined by a CMB map as a function of sky coverage, pixel noise, and beam size. Assuming only that the primordial density perturbations were adiabatic and with no prior information on the...

Evolution of Information and Complexity in an Ever-Expanding Universe

Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.
