摘要：
Dark matter could be composed of compact dark objects (CDOs). These objects may interact very weakly with normal matter and could move freely inside the Earth. A CDO moving in the inner core of the Earth will have an orbital period near 55 min and produce a time-dependent signal in a gravimeter. Data from superconducting gravimeters rule out such objects moving inside the Earth unless their mass m(D) and or orbital radius a are very small so that m(D)a < 1.2 x 10(-13)M(circle plus)R(circle plus). Here, M-circle plus and R-circle plus are the mass and radius of the Earth, respectively.
