In this paper, we introduce a brief history of gravitational-wave detection experiments conducted by scientists over the last 55 years to detect graviational waves experimentally based on Einstein's theoretical prediction in 1916 and Weber's pioneering challenges in the 1960s. In particular, we describe both the status of the advanced LIGO (Laser Interferometer Gravitational-wave Observatory) recently developed and the reason the LIGO project may be the most promising candidate among gravitational-wave detectors after the Weber's bar detector. Furthermore, we present various models of next-generation gravitational-wave detectors and the research status of the Korean Gravitational Wave Group (KGWG).
