On a regular modified Schwarzschild spacetime    [PDF]

Hristu Culetu

A modified version of the Schwarzschild geometry is proposed. The source of curvature comes from an anisotropic fluid with $p_{r} = -\rho$ and fluctuating tangential pressures. The event horizon has zero surface gravity but the invariant acceleration of a static observer is finite there. The Tolman - Komar energy of the gravitational fluid changes sign on the horizon, equals the black hole mass at infinity and is vanishing at $r = 0$. The metric has no signature flip when the horizon is crossed and all the physical parameters are finite everywhere.
