Dynamics of Anisotropic Universes
We present a general study of the dynamical properties of Anisotropic Bianchi Universes in the context of Einstein General Relativity. Integrability results using Kovalevskaya exponents are reported and connected to general knowledge about Bianchi dynamics. Finally, dynamics toward singularity in Bianchi type viii and ix universes are showed to be equivalent in some precise sence. 1 Homogeneous...
متن کاملDynamics of compact homogeneous universes
A complete description of dynamics of compact locally homogeneous universes is given, which, in particular, includes explicit calculations of Teichmüller deformations and careful counting of dynamical degrees of freedom. We regard each of the universes as a simply connected four dimensional spacetime with identifications by the action of a discrete subgroup of the isometry group. We then reduce...
متن کاملDynamics Study of Ankle Joint during Quiet Standing Balance Control with Emphasis on Dominant and Non-dominant Lower Limb
Purpose: The present study aimed to evaluate the effect of dominant lower limb on the correlation between some of the dynamic variables of ankle joint and center of mass during quiet standing balance control. Methods: Twelve healthy females with no known neurological or musculoskeletal disorders, with the mean age of 26±3.5 years, participated in this study. Motion analysis system, force ...
متن کاملComparison Effect of Quiet Eye and Quiet Mind Training on learning of Dart Throws Skill
The aim of present study is to investigate effect of the quiet eye and quiet mind training on the dart throw learning. Thirty young males were selected with 24.53 mean aged through convenience sampling and randomly divided into quiet eye group, quiet mind group and control group. The study was conducted in four phases, including: Pre-test, training in quiet eye and quiet mind training, retentio...
متن کاملParallel Universes
I survey physics theories involving parallel universes, which form a natural four-level hierarchy of multiverses allowing progressively greater diversity. Level I: A generic prediction of inflation is an infinite ergodic universe, which contains Hubble volumes realizing all initial conditions — including an identical copy of you about 10 29 m away. Level II: In chaotic inflation, other thermali...
