"Exploring the Possibility of Dual Gravitational Lenses"

A theoretical physicist has explored the possibility of multiple gravitational lenses providing extra amplification of light to create a communication bridge between distant civilizations. However, the study found no advantages or additional signal amplification in a two-lens system compared to a single lens system. While the concept is fascinating, the idea of using double gravitational lenses for long-distance communication remains unlikely and currently confined to science fiction.
