The next decade will be an exciting epoch in the field of general relativity: Gravitational-wave detectors will directly detect gravitational waves for the first time, and subsequently clarify coalescing mechanism of binary compact objects such as binary neutron stars and formation mechanism of black holes. Simultaneous detection of gravitational waves and electromagentic waves may determine the central engine of gamma-ray bursts (GRBs). Mechanism of supernova may be constrained if gravitational waves from it are detected. Numerical relativity plays an important role for theoretically predicting gravitational waveforms and mechanism of general relativistic astrophysical phenomena such as GRBs. I will review the perspective of the field of gravitational waves, and also talk the current activity of numerical relativity.
