It is shown that the extra coordinate of 5D induced-matter and membrane theory is related in certain gauges to the inertial rest mass of a test particle. This implies that the Weak Equivalence Principle is a geometric symmetry, valid only in the limit in which the test mass is negligible compared to the source mass. Exact solutions illustrate this, and show the way to possible resolutions of the cosmological-constant and hierarchy problems. 

THE EQUIVALENCE PRINCIPLE AS A PROBE FOR HIGHER DIMENSIONS

Higher-dimensional theories of the kind which may unify gravitation with particle physics can lead to significant modifications of general relativity. In five dimensions, the vacuum becomes

An embedding for general relativity and its implications for new physics

We show that any solution of the 4D Einstein equations of general relativity in vacuum with a cosmological constant may be embedded in a solution of the 5D Ricci-flat equations with an effective 4D

MASS, PARTICLES AND WAVES IN HIGHER DIMENSIONS

Using 5D membrane/induced-matter theory as a basis, we derive the equations of motion for a novel gauge. The latter admits both particle and wave behaviour, as well as super-communication (wherein

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

ON THE CLASSICAL CONFINEMENT OF TEST PARTICLES TO A THIN 3-BRANE IN THE ABSENCE OF NON-GRAVITATIONAL FORCES

The classical confinement condition of test particles to a brane universe in the absence of non-gravitational forces is transformed using the Hamilton–Jacobi formalism. The transformed condition

The geometrical unification of gravity with its source

I give a personal retrospect covering the years during which Mashhoon, myself and others developed a unification of the gravitational field and its source (matter). In this geometrical approach,

THE BIG BANG AS A PHASE TRANSITION

We study a five-dimensional cosmological model, which suggests that the universe began as a discontinuity in a scalar (Higgs-type) field, or alternatively as a conventional four-dimensional phase

Wave mechanics and general relativity: a rapprochement

Using exact solutions, we show that it is in principle possible to regard waves and particles as representations of the same underlying geometry, thereby resolving the problem of wave-particle

Paul Wesson and Space-Time-Matter Theory

A short scientific biography is given of physicist Paul Wesson (1949-2015), who published over 300 works encompassing the fields of astrobiology, astrophysics, geophysics, cosmology, and relativity;

The Experimental Verdict on Spacetime from Gravity Probe B

Concepts of space and time have been closely connected with matter since the time of the ancient Greeks. The history of these ideas is briefly reviewed, focusing on the debate between "absolute" and

Mass and charge from higher dimensional geometry

We explore ways in which phenomenological physical quantities such as the rest mass and electric charge of a particle could be explained as properties of higher dimensional geometry. In 5D, it is

Technical results are presented on motion in N(>4)D manifolds to clarify the physics of brane theory, Kaluza–Klein theory, induced-matter theory, and string theory. The so-called canonical or warp

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.,

A Class of Kaluza-Klein Solutions Curved in 4D and Flat in 5D

We give a broad class of solutions of the Kaluza-Klein equations that is static, spherically symmetric in 3D, curved in 4D and flat in 5D. These solutions generalize others that have been applied in

Extra Force in Brane Worlds

By carefully analyzing the geodesic motion of a test particle in the bulk of brane worlds, we identify an extra force which is recognized in spacetime of one lower dimensions as a non-gravitational
