The anomalous deceleration of spacecraft Pioneer 10,11,etc could be interpreted as signal delay effect reflected in virtual scale, in analogy to a scale conversion in relative motion between the co-varying virtual and the invariant real scales( http://arxiv.org/html/math-ph/0001019v5). A finite speed of gravity faster than light was implied
( http://arXiv.org/html/physics/0001034v2 ). A lower limit for a speed of gravity was derived by pluging in the ratio of nominal to anomalous decelerations via scale conversion
( http://arXiv.org/html/physics/0001034 ). Here we suggest a few possible ways including some astronomical events of planetary alignments. If we can measure the precise time of the event in gravitational effect, and that of the equivalent optical effect, then through time difference between these two effects for the same event we may derive speed of gravity. A ball-borne pendulum seems to be a good instrument to serve for this purpose in the well defined gravitational variation in azimuthal precession
during Sun-Mercury-Earth conjunction. A directly measured speed of gravity faster than light is the necessary condition to infer that there exists a gravitational horizon. Dark energy may be owing to mutually interactive gravitational horizons of neighbors in the neighborhood of universes.Our Universe may not be alone.The sufficient condition for this conjecture is that the dark energy would be increasing with the age of Universe.
