Abstract

The method of characteristics is used to find a coordinate system that is regular on the surface r = 2m(t) of the metric ds2 = −[1 − 2m(t)/r] dt2 + [1 − 2m(t)/r]−1 dr2 + r2 dθ2 + r2 sin2θ dφ2 . It is shown that the surface r = 2m(t) is an event horizon, and therefore the metric, for m(t) ≥ 0 may be interpreted as a black hole with a time dependent horizon. For the special case where m is time-independent, the coordinate transformation obtained using the method reduces to Eddington-Finkelstein coordinates.
