- The accessible space-time (physical region) is defined by
- In the coord., the metric (eq.4) is singular
at and , where the apparent horizon is located.
- In the coord., the metric (eq.6) is
Minkowskian for . The / coordinates describe the
interior/exterior of the black hole. These two regions are causally
- In the coord., the metric (eq.8) is
singular in the limits and , if
. The horizon is located at . It takes a
finite amount of proper time for all time-like geodesics with
to reach the central singularity at , where all the matter is concentrated
after the collapse.

The light cones are looking upwards everywhere.
The curves denoted by AH and EH are the apparent and event horizons
