Phys. Rev. Lett. 87, 231302 (2001) [4 pages]Gravitational Collapse on the Brane: A No-Go TheoremReceived 3 August 2001; published 13 November 2001 We investigate how braneworld gravity affects gravitational collapse and black hole formation by studying Oppenheimer-Snyder–like collapse on a Randall-Sundrum–type brane. Without making any assumptions about the bulk, we prove a no-go theorem: the exterior spacetime on the brane cannot be static, which is in stark contrast with general relativity. We also consider the role of Kaluza-Klein energy density in collapse, using a toy model. © 2001 The American Physical Society URL:
