Gamma Ray Bursts and CETI
Abstract
Gamma ray burst sources are isotropically distributed. They could be located at distances 1000 AU. (Katz JK92) GRB signals have many narrow peaks that are unresolved at the millisecond time resolution of existing observations. JK87 CETI could use stars as gravitational lenses for interstellar gamma ray laser beam communication. Much better time resolution of GRB signals could rule out (or confirm?) the speculative hypothesis that GRB = CETI.
