Romero	Presentism meets black holes	2014	17	.pdf	application/pdf	6906	769	73	It has been argued that at least some versions of presentism are consistent with time-orientable models of general relativity. Keywords Presentism · space-time · black holes · relativity · fourdimensionalism of the future relative to the past for any region of space-time is, given special In the case of more general space-times, represented by manifolds with intrinsic curvature, such transformations can only be local. In order to introduce gravitation in a general space-time we define a metric tensor gµν, such that its components can be related to those of a locally The black hole region, BH, of such space-time is BH = the black hole is the metric and, consequently, space-time curvature. Fig. 3 Space-time diagram in Schwarzschild coordinates showing the light cones close to space-times with black holes, the horizon is not only a null surface, it is also a relativity self-defeats her position if space-time allows for black holes.	./cache/work_4czg5ksbjzcsrouferhs2emsne.pdf	./txt/work_4czg5ksbjzcsrouferhs2emsne.txt
