N2 - The gravitational deflection of light provided one of the first observational confirmations of general relativity. Now we are considering how gravitational lensing can provide novel tests of Einstein's theory, and intriguing alternatives. We have developed a comprehensive analytical framework for lensing by black holes, and made concrete predictions that are testable with existing or planned instruments. Two examples: (1) In parametrized post-Newtonian models, there are universal relations among lensing observables. Observed violations of these relations would falsify all PPN models in one fell swoop. (2) In braneworld gravity, there could be many primordial black holes in our Solar System that would produce interference fringes in the energy spectra of gamma ray bursts, which could be detected with the GLAST satellite starting in 2007.
