It may be possible to construct a laser interferometer gravitational wave antenna in space with hrms ~ 10-23 at f ~ 0.1 Hz in ~2020. This decihertz antenna may be called the Decihertz Interferometer Gravitational Wave Observatory and Big Bang Observer (DECIGO/BBO). The analysis of 1-10 yr of observational data of the coalescing binary neutron stars or black holes at the distance of ~300 Mpc will give us the spatial position within approximately an arcminute and the time of the coalescence within ~0.1 s beforehand. With the knowledge of the accurate position and the time of the final merging event, the follow-up simultaneous observation using high-frequency (f ~ 100 Hz) gravitational wave antennae as well as electromagnetic wave antennae from the radio frequency to the ultra-high-energy gamma ray will reveal the physics in the enigmatic event of the coalescence and the formation of the black hole.
