Electrostatic Equilibrium of Two Spherical Charged Masses in General Relativity

Approximate solutions representing the gravitational-electrostatic balance of two arbitrary point sources in general relativity have led to contradictory arguments in the literature with respect to the condition of balance. Up to the present time, the only known exact solutions which can be interpreted as the non-linear superposition of two spherically symmetric (Reissner-Nordstr om) bodies wi...

General-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...

On the two-body problem in general relativity

We consider the two-body problem in post-Newtonian approximations of general relativity. We report the recent results concerning the equations of motion, and the associated Lagrangian formulation, of compact binary systems, at the third post-Newtonian order (∼ 1/c beyond the Newtonian acceleration). These equations are necessary when constructing the theoretical templates for searching and anal...

Two-dimensional Black Holes and Planar General Relativity

The Einstein-Hilbert action with a cosmological term is used to derive a new action in 1+1 spacetime dimensions. It is shown that the two-dimensional theory is equivalent to planar symmetry in General Relativity. The two-dimensional theory admits black holes and free dilatons, and has a structure similar to two-dimensional string theories. Since by construction these solutions also solve Einste...

Noncommutative general relativity

We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommutative spacetimes to be volume-preserving transformations. Local Lorentz invariance is treated as a gauge theory with the spin connection field taken in the so(3,1) enveloping algebra. The resulting theory appears to be...
