摘要
Einstein's general relativistic wave equation predicts a gravitational wave, and that prediction is confirmed by an astronomical observation. His equation of motion, on the other hand, predicts that a gravito-radiative force, due to a gravito-tensor potential, exists. The gravito-radiative force propagates through space, tries to induce a mass quadrupole moment in Earth's crust, through the rotation of Earth with respect to the center of Earth. However, Earth's crust is rigid, and resists such deformation. Only pendulum-bobs co-moving with Earth's crust are accelerated horizontally. We placed two verticity meters (motionless pendulums) at Boulder, Colorado, and observed some gravitational waves as coincidental displacements of their bobs. Later two more independent verticity meters are placed in the same room and coincidencal displacements in all four verticity meters are observed. Typical gravitational wave we observed is an impulse of about 10(-8) m/s, and that can be explained by a mass of 10(39) kg moving at the galactic center with vv/c = 10(5)g, where v are its speed and acceleration, respectively. The corresponding energy decay rate is about 10(51) J/s at the galactic center.
