On a regular modified Schwarzschild spacetime

Understand

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 $r = 0$.
