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. … WebThus, trapped air does not necessarily block cell attachment as has been suggested in the literature.

"Websurface gravity is sensitive to the causal description of the evolving marginally trapped surface. It is shown in the paper that for the FRW case, if we deﬁne the per-fect ﬂuid with the equation of state given by, ρ = ωP, for ω < 1/3, the marginally trapped surface is timelike. The Kodama-Hayward surface gravity is shown in [16] to " - On the formation of trapped surface

Web29 de abr. de 1993 · Previously suggested definitions of averagely trapped surfaces are not well defined properties of 2-surfaces and can include surfaces in flat spacetime. A natural definition of averagely trapped surfaces is that the product of the null expansions be positive on average.

WebTrapped surfaces became a central concept in the completion of Penrose’s proof of the singularity theorem. The topological methods he introduced are now invaluable in the study of our curved universe. A one-way street to the end of time. Once matter begins to collapse and a trapped surface forms, nothing can stop the collapse from continuing.
