Finkelstein constructs a regular analytic continuation across the Schwarzschild surface and explains its one-way causal character in time-reversed branches, while the paper itself records that this continuation is not the complete Schwarzschild spacetime.
Scientific scope
Finkelstein constructs a regular analytic continuation across the Schwarzschild surface and explains its one-way causal character in time-reversed branches, while the paper itself records that this continuation is not the complete Schwarzschild spacetime. The coordinates describe the stated classical Schwarzschild spacetime and make the horizon’s causal asymmetry explicit. Regularity at the horizon is not regularity at the central singularity. This is not a model of every rotating/charged collapse, a quantum resolution or the full later maximal extension. Other coordinate and causal contributions remain separate.
