We define a metrical theory of gravity with preferred Newtonian frame (X i (x), T (x)) by It allows a condensed matter interpretation which generalizes LET to gravity. The Ξ-term influences the age of the universe. Υ > 0 avoids the big bang singularity. This solves the horizon problem without inflation. Most quantum GR problems disappear. An atomic hypothesis solves the ultraviolet problem by e...

the analytic signal method is usually used to interpret the magnetic and gravity anomalies. the main advantage of using analytic signal method in interpretation of magnetic source parameters from magnetic anomalies is that the amplitude dip of the analytic signal is independent of directional parameters like magnetization and the dip of the source. using the coefficient of the amplitude to esti...

introduction: wavelet transform is one of the useful and suitable tools for time series and signal analysis. nowadays wavelet transform is frequently used in geophysical data processing and interpretation, especially seismic data. however, the use of this method isn’t widespread in gravity and geomagnetic. fedi and quarta (1998), martelet et al. (2001) and de oliveira lyrio (2004) used the wave...

We discuss the confined phase in D0-brane matrix model and its interpretation terms of gravity using gauge/gravity duality based on [1]. In particular, at very low energies we expect system to describe M-theory region not type IIA supergravity provide numerical evidence for this.

Given recent observational results from the BICEP2 and Planck collaborations regarding the ratio of power in tensor to scalar modes in the cosmic microwave background radiation, and the implications of this ratio for the possible existence of large gravity waves resulting from inflation, it is of current interest to investigate models of inflation which are capable of producing large gravity wa...

gravity acceleration data have grand pursuit for marine applications. due to environmental effects, marine gravity observations always hold a high noise level. in this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. on the one hand, harmonic spline functions have great capability for local gravity ...

We consider a classical condensed matter theory in a Newtonian framework where conservation laws ∂tρ+ ∂i(ρv ) = 0 ∂t(ρv ) + ∂i(ρv v + p) = 0 are related with the Lagrange formalism in a natural way. For an “effective Lorentz metric” gμν it is equivalent to a metric theory of gravity close to general relativity with Lagrangian L = LGR − (8πG)(Υg − Ξ(g + g + g)) √−g We consider the differences be...

‘Holographic’ relations between theories have become an important theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard ’t Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic ‘AdS/CFT’ dua...

Ashtekar’s formulation for canonical quantum gravity is known to possess the topological solutions which have their supports only on the moduli space N of flat SL(2,C) connections. We show that each point on the moduli spaceN corresponds to a geometric structure, or more precisely the Lorentz group part of a family of Lorentzian structures, on the flat (3+1)-dimensional spacetime. A detailed an...

To allow for geophysical interpretation of observed gravity gradients, several corrections must be applied. In this article expressions for gravimetric forward modeling of bathymetric (ocean density contrast) stripping corrections to GOCE gravity gradient observables are evaluated numerically. The generic expression for the bathymetric gravitational potential utilizes a depth-dependent seawater...
