WAVE RUNNER  Joseph Weber (shown in 1969) announced he detected a gravity wave using his aluminum cylinder detector at University of Maryland in College Park. It took nearly five decades for LIGO to confirm that gravity waves can be detected.

Gravity waves evidence

The long search for gravitational waves … may be in the final lap…. Rotating binary stars or, perhaps, other galaxies like the Milky Way but far beyond it, or the center of the Milky Way itself, are likely sources for gravitational radiation. — Science News, June 22, 1968.

Update

Although Joseph Weber, a physicist at the University of Maryland, announced a gravity wave detection in 1969, no one could verify his claim. It took almost another 50 years for researchers to directly detect gravitational waves (SN: 3/5/16, p. 24). Those spacetime ripples from two merging black holes, glimpsed
