"Exploring the Possibility of Double Gravitational Lenses"

The possibility of using multiple gravitational lenses as a communication bridge between distant civilizations has been explored by theoretical physicist Viktor T Toth. However, his research suggests that a two-lens system does not offer any advantages or additional signal amplification over a single-lens system. While the concept is fascinating, it is unlikely that double gravitational lenses can be detected at this time, making the idea of using them as a long-distance cosmic telephone remain science fiction for now.
