We note that under the assumption of an asymptotically ﬂat space-time, the presence of a trapped surface usually guarantees the existence of the event horizon [17–20]. We study the formation of marginally trapped surfaces in a head-on collision … A trapped null surface is a set of points defined in the context of general relativity as a closed surface on which outward-pointing light rays are actually converging (moving inwards). Trapped null surfaces are used in the definition of the apparent horizon which typically surrounds a black hole. We take a (compact, orientable, spacelike) surface, and find its outward pointing normal vectors. …
