A New Solution of Einstein Vacuum Field Equations

Understand

A new solution of Einstein's vacuum field equations is discovered which appears as a generalization of the well-known Ozsvath-Schucking solution and explains its source of curvature which has otherwise remained hidden.

• Curiously, the new solution has a vanishing Kretschmann scalar and is singularity-free despite being curved.
• The discovery of the new solution is facilitated by a new insight which reveals that it is always possible to define the source of curvature in a vacuum solution in terms of some dimensional parameters.
• As the parameters vanish, so does the curvature.
