We attempt to treat the very early Universe according to quantum mechanics. Identifying the scale factor of the Universe with the width of the wave packet associated with it ,we show that there cannot be an initial singularity and that the Universe expands. Invoking the correspondence principle, we obtain the scale factor of the Universe and demonstrate that the causality problem of the standar...

Much of the published work regarding the Isotropic Singularity is performed under the assumption that the matter source for the cosmological model is a barotropic perfect fluid, or even a perfect fluid with a γ-law equation of state. There are, however, some general properties of cosmological models which admit an Isotropic Singularity, irrespective of the matter source. In particular, we show ...

Abstract This paper is an attempt to study the thermodynamics of structure formation in large scale universe non local gravity using Boltzmann statistics and Tsallis statistics. The partition function obtained both approaches corresponding properties are evaluated. important thing about that we surprisingly get divergence free integrals thus stress upon fact nonlocal singularity model gravity.

The problem of the speed objects inside Schwarzschild black hole is considered. general result that value relative following their non-zero angular momentum trajectories, both geodesic and non-geodesic character, when approaching ultimate singularity, tends to light. There only one exception move in same plane have parallel momenta. This outcome appears a deeper sense: it reflects anisotropic c...

Ceramic thermal barrier coatings are commonly used in gas turbine hot components (e.g., combustor liners/buckets and guide vane platforms). In components that are only partially coated or have cooling-air outlets, coating-end stress singularities may lead to the spallation of the coating. Depending on the geometry of the transition from coated to uncoated material, the severity of the stress si...

Fundamental theories of quantum gravity such as supergravity include a four form field strength which contributes to the cosmological constant. The inclusion of such a field into our theory of open inflation [1] solves the problem of the most likely universe being too empty. It also allows an anthropic solution to the cosmological constant problem in which cosmological constant gives a small bu...
