No gravity‐wave confirmation by the new experiments Available to Purchase

Two new experiments have failed to detect gravity waves of the intensity originally reported by Joseph Weber in 1969–70. Richard L. Garwin and James L. Levine of IBM Research Center, operating a Weber‐type antenna at 1695 Hz, report no signals after 18 days of serious data collection. At Bell Labs, J. Anthony Tyson, who has a Weber‐type antenna sensitive to 710 Hz, found no signals after three months of operation in the present set‐up.
