Single gravity-wave detector results contrasted with previous coincidence Detections

Coincidence detectors of Weber have given a 10:1 ratio (R*) of prompt to delayed coincidences. Simplified analysis indicates that such an R* would require daily gravity-wave incidence rate and energy depositions that would have been seen in the single-bar detector of the preceding Letter (and were not), suggesting that Weber's 1969-1970 events were not produced by gravity waves or that such waves do not exist in similar numbers and intensity in 1973. © 1973 The American Physical Society.
