Recent cosmological observations suggest the existence of a positive cosmological constant
Λ with the magnitude Λ (Gℏ/c3)≈ 10− 123. This review discusses several aspects of the …

The complete general-relativistic plane-wave space-times (gravitational, electromagnetic, or
both) are examined in relation to the focusing effect they exert on null cones. The following …

Kruskal's transformation of the Schwarzschild metric is generalized to apply to the stationary,
axially symmetric vacuum solution of Kerr, and is used to construct a maxiInal analytic …

The Schwarzchild manifold of general relativity theory is unsatisfactory as a particle model
because the singularity at the origin makes it geodesically incomplete. A coupling of the …

The quasistellar object, the pulsar, the neutron star have all come onto the scene of physics
within the space of a few years. Is the next entrant destined to be the black hole? If so, it is …

The``generalized Schwarzschild''metric discovered by Newman, Unti, and Tamburino, which
is stationary and spherically symmetric, is investigated. We find that the orbit of a point under …

With the introduction of multiply connected topologies into physics, a question of causality
arises. There are alternative routes between two points in a multiply connected space …

This book is about black holes, one of the most intriguing objects of modern theoretical
physics and astrophysics. For many years, black holes have been considered as interesting …

A bstract We show that the geometry of the asymptotic infinities of Minkowski spacetime (in
d+ 1 dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups …
