Abstract :
After reviewing the importance of light as a probe for testing the structure of space-time, we describe the GINGER project. GINGER will be a three-dimensional array of large-size ring-lasers able to measure the de Sitter and Lense–Thirring effects. The instrument will be located at the underground laboratory of Gran Sasso, in Italy. We describe the preliminary actions and measurements already under way and present the full road map to GINGER. The intermediate apparatuses GP2 and GINGERino are described. GINGER is expected to be fully operating in few years.
