SUMMARY:Two Manifestations of the Failure of General Relativity - George C
 hapline (Lawrence Livermore National Laboratory\, California)

DESCRIPTION:GR is bound to fail under some circumstances due to its incomp
 atibility with quantum mechanics. In\nthis talk two examples of possible f
 ailures of GR that may be confirmed in the very near future are\ndescribed
 . The first example relates to the fact that GR cannot provide an exact de
 scription of any\nrotating object. In the case of a rotating compact objec
 t GR may not be even qualitatively correct.\nIn particular\, we will argue
  that in reality rotating compact objects have a Godel-like vortex\ncore. 
 The prediction is that the highly collimated jets seen emerging from AGN o
 riginate from\ninside the compact object. The second example relates to th
 e fact that GR must fail as one\napproaches an event horizon. As a consequ
 ence cosmic rays hitting the surface of a compact object\nwill produce a g
 amma ray spectrum with a dip below 70 MeV. In the case of the compact obje
 ct\nlocated at Sg A* it may be possible to see this spectral anomaly with 
 GLAST.
