Query: Possibility of Direct Measurement of the Acceleration of the Universe
  Using 0.1 Hz Band Laser Interferometer Gravitational Wave Antenna in Space   It may be possible to construct a laser interferometer gravitational wave
antenna in space with $h_{rms}\sim 10^{-27}$ at $ f\sim 0.1{\rm Hz}$ in this
century. We show possible specification of this antenna which we call DECIGO.
Using this antenna we show that 1) typically $ 10^5$ ($10^4\sim 10^6$) chirp
signals of coalescing binary neutron stars per year may be detected with S/N
$\sim 10^4$. 2) We can directly measure the acceleration of the universe by ten
years observation of binary neutron stars. 3) The stochastic gravitational
waves of $\Omega_{GW}\gsim 10^{-20}$ predicted by the inflation may be detected
by correlation analysis for which effects of the recent cosmic acceleration
would become highly important. Our formula for phase shift due to accelerating
motion might be also applied for binary sources of LISA.
