description Joseph Weber Overview
Joseph Weber was an American physicist who helped establish experimental gravitational-wave research. Working at the University of Maryland, he developed resonant-mass detectors, commonly called Weber bars, during the 1960s and reported signals that he interpreted as gravitational waves. Those reports were not confirmed by later experiments, but his detectors and methods influenced the development of the field and the search for direct evidence of gravitational radiation.
help Joseph Weber FAQ
Who was Joseph Weber?
Joseph Weber was an American physicist at the University of Maryland who helped establish experimental gravitational-wave research. He developed resonant-mass detectors known as Weber bars during the 1960s.
What is a Weber bar?
A Weber bar is a large resonant metal cylinder designed to vibrate when affected by a gravitational wave. Weber built detectors using this approach and placed instruments at separate locations to look for coincident signals.
Did Joseph Weber’s claimed detections become accepted?
Other researchers could not reproduce the high event rates Weber reported, and his claims were not accepted as confirmed detections. His work nevertheless helped launch the field that later led to LIGO.
How does Weber’s work relate to LIGO?
Weber used resonant bars, while LIGO uses laser interferometers with long perpendicular arms. LIGO’s first direct gravitational-wave detection was announced in 2016 from a signal observed in 2015.
