General Relativity With An Auxiliary Dimension
I consider an extension of General Relativity by an auxiliary non-dynamical dimension that enables our space-time to acquire an extrinsic curvature. Obtained gravitational equations, without or with a cosmological constant, have a selfaccelerated solution that is independent of the value of the cosmological constant, and can describe the cosmic speedup of the Universe as a geometric effect.

متن کاملGeneral Relativity: An Informal Primer
General relativity, and its application to cosmological models such as inflation, is a remarkably beautiful and elegant theory. Yet newcomers to the field often face at least three types of challenges: conceptual, mathematical, and notational. Over the past century, physicists and mathematicians have developed a remarkably compact formalism and notation for working with general relativity, whic...
متن کاملEllipsoidal shapes in general relativity: general definitions and an application
A generalization of the notion of ellipsoids to curved Riemannian spaces is given and its possible use to describe the shapes of rotating bodies in general relativity is considered. As an illustrative example, stationary, axisymmetric perfect-fluid spacetimes with a so-called confocal inside ellipsoidal symmetry are investigated in detail under the assumption that the 4-velocity of the fluid is...
متن کاملGeneral-relativistic Visualization General Relativity
I n our previous article about special-relativistic visualization,1 we described what the travelers from our highly developed civilization observed when they passed the Earth; now, they set out for the Cygnus X-1 binary system, which is roughly 6,000 light years away. The Cygnus X-1 system consists of a super giant variable star (HDE 226868) and a very compact object—presumably a black hole—wit...
متن کاملScale Relativity Theory for an Arbitrary Fractal Dimension
Considering the fractal structure of space-time, a Burgers – Korteweg – de Vries (BKdV) type equation is obtained. Particularly, if the motions of the “non-differentiable fluid” are irrotational, the BKdV type equation is reduced to a non-linear Schrödinger type equation. In this case, the scalar complex velocity field simultaneously becomes wave function.
