Sport has become a highly commercialised business, in recent times sports have utilised considerable corporate sponsorship and advertising opportunities (Slack, 1998), to improve their welfare and popularity. “Today, sport is a big business and big businesses are involved in sport” (Slack, 1998, p1). Major spectator sports produce many marketable opportunities (Slack, 1998), however, the analog...
The military reform in Russia is a big hoax. All military reforms in other countries have amounted to the demobilization of the old army and the creation of a new one, which is based on a different recruitment mode, doctrine, etc. This has not been done in Russia. The old army has not been disbanded, no new one has been built, and meanwhile the military are decaying somewhere in between” (Anony...
After a brief review of current scenarios for the resolution and/or avoidance Big Bang, an alternative hypothesis is put forward implying infinite increase in complexity towards initial singularity. This may result effective non-calculability which would present obstruction to actually reaching beginning time. proposal motivated by appearance certain infinite-dimensional duality symmetries inde...
New nondiagonal G2 inhomogeneous cosmological solutions are presented in a wide range of scalar-tensor theories with a stiff perfect fluid as a matter source. The solutions have no big-bang singularity or any other curvature singularities. The dilaton field and the fluid energy density are everywhere regular, too. The geodesic completeness of the solutions is investigated. 04.50.+h, 04.20.Jb, 9...
We study the cosmology of the Randall-Sundrum brane-world where the Einstein-Hilbert action is modified by curvature correction terms: a four-dimensional scalar curvature from induced gravity on the brane, and a five-dimensional Gauss-Bonnet curvature term. The combined effect of these curvature corrections to the action removes the infinite-density big bang singularity, although the curvature ...
In most models, inflation is driven by the potential energy of a scalar field. This has similar effects as adding vacuum energy or, equivalently, a positive cosmological constant. For these models Wald [1] proved a cosmic no hair theorem, which implies that an initial shear is inflated away [2]. A couple of years ago, a new mechanism of inflation has been proposed, where inflation is due to the...
