Recent criticism of higher-dimensional extensions of Einstein's theory is considered. This may have some justification in regard to string theory, but is misguided as applied to five-dimensional (5D) theories with a large extra dimension. Such theories smoothly embed general relativity, ensuring recovery of the latter's observational support. When the embedding of spacetime is carried out in accordance with Campbell's theorem, the resulting 5D theory naturally explains the origin of classical… 

Gauge symmetries and isometries in higher dimensions

We study the invariance properties of five-dimensional metrics and their corresponding geodesic equations of motion. In this context a number of five-dimensional models of the Einstein–Gauss–Bonnet

Accounting for exotic matter and the extreme radial tension in Morris–Thorne wormholes of embedding class one

The embedding of a curved spacetime in a higher-dimensional flat spacetime has continued to be a topic of interest in the general theory of relativity, as exemplified by the induced-matter theory.

Periodic signature change in spacetimes of embedding class one

It is proposed in this paper that the free parameter occurring in the transformation be a periodic function of time and the result is a mathematical model that can be interpreted as a periodic change in the signature of the embedding space.

Towards a Geometrization of Renormalization Group Histories in Asymptotic Safety

Considering the scale-dependent effective spacetimes implied by the functional renormalization group in d-dimensional quantum Einstein gravity, we discuss the representation of entire evolution

M ay 2 01 7 New asymptotic Anti-de Sitter solution with a timelike extra dimension in 5 D relativity

In 5D relativity, the usual 4D cosmological constant is determined by the extra dimension. If the extra dimension is spacelike, one can get a positive cosmological constant Λ and a 4D de Sitter (dS)

The Importance of Scalar Fields as Extradimensional Metric Components in Kaluza-Klein Models

Extradimensional models are achieving their highest popularity nowadays, among other reasons, because they can plausible explain some standard cosmology issues, such as the cosmological constant and

Interacting Induced Dark Energy Model

Following the idea of the induced matter theory, for a non–vacuum five–dimensional version of general relativity, we propose a model in which the induced terms emerging from the extra dimension in

A model for dark energy based on the theory of embedding

A long-standing topic of interest in the general theory of relativity is the embedding of curved spacetimes in higher-dimensional flat spacetimes. The main purpose this paper is to show that the

Possible existence of time machines in a five-dimensional spacetime

The idea of constructing a time machine is not new and even received a boost thanks to the realization that a traversable wormhole could be converted to a time machine. This also implied that one



Application of the Campbell-Magaard theorem to higher dimensional physics

Stated succinctly, the original version of the Campbell–Magaard theorem says that it is always possible to locally embed any solution of four-dimensional general relativity in a five-dimensional

Phenomenology, astrophysics and cosmology of theories with submillimeter dimensions and TeV scale quantum gravity

We recently proposed a solution to the hierarchy problem not relying on low-energy supersymmetry or technicolor. Instead, the problem is nullified by bringing quantum gravity down to the TeV scale.

Dynamics in Kaluza-Klein Gravity and a Fifth Force

Using a novel coordinate system, we rederive the field equations and equa tions of motion for 5-dimensional relativity in the general case where the metric can depend on all 5 coordinates (i.e.,

Not even wrong : the failure of string theory and the continuing challenge to unify the laws of physics

"Not Even Wrong" tells a fascinating and complex story about human beings and their attempts to come to grips with perhaps the most intellectually demanding puzzle there is: how does the world work

An Alternative to compactification

Conventional wisdom states that Newton's force law implies only four noncompact dimensions. We demonstrate that this is not necessarily true in the presence of a nonfactorizable background geometry.

Decaying dark energy in higher-dimensional gravity

Aims. We use data from observational cosmology to put constraints on higher-dimensional extensions of general relativity in which the effective four-dimensional dark-energy density (or cosmological

Gauge-dependent cosmological 'constant'

When the cosmological constant of spacetime is derived from the 5D induced-matter theory of gravity, we show that a simple gauge transformation changes it to a variable measure of the vacuum which is
