Abstract

Gravitational waves are ripples in the curvature of spacetime that propagate outward from the source of radiation through waves. In this paper, the basic principles of general relativity are discussed, including a brief derivation of gravitational waves, the gravitational wave equation, the means of gravitational wave detection, and the prospects for the future. In addition, this paper will demonstrate the observations of the gravitational wave GW151226 observed by LIGO, indicating its source data and other processed data. According to the analysis, the GW151226 event was produced by the merger of a black hole of 7.5 times the mass of the Sun with a black hole of 14.2 times the mass of the Sun, where the lost double solar mass was propagated as a gravitational wave. These theoretical and observational results clarify the reality of gravitational waves predicted in general relativity; however, this result is still criticized by a few scholars, which will be discussed accordingly. The future outlook for gravitation detection will be presented. These results shed light on guiding further exploration of gravitational wave detection.
