The experiment described in the given statement refers to the Evolved Laser Interferometer Space Antenna (eLISA), also known as NGO (Next Generation Observatory) or LISA Pathfinder. It is a space-based gravitational wave observatory, which aims to detect and study gravitational waves. The experiment involves three spacecraft flying in a triangular formation, with lasers passing between them to measure the distortion of space-time caused by gravitational waves. This experiment is expected to be more sensitive than the Laser Interferometer Gravitational-Wave Observatory (LIGO), which detected gravitational waves in 2015.
