An artist's depiction of two black holes colliding to merge into one, an event that led to the Nobel Prize for Physics winning detecting of gravitational waves by the Laser Interferometer ...

On April 1, the teams behind the three gravitational wave detectors started them up for a new observational run, the first with all three operating in parallel for the full run. With the benefit of ...

Since extensive upgrades to improve sensitivity, gravitational wave detectors in the United States and Europe have detected ever-so-slight ripples in the fabric of space that appear to indicate three ...

Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

Two projects born a century ago in the mind of Albert Einstein, and the scientific leaders behind them, won the 2017 Nobel Prize in physics for detecting gravitational waves. Rainer Weiss won one half ...

The powerful collision of two black holes, depicted in a computer simulation, was detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO.

As one of the key experimentalists to conceptualize and then build one of the biggest experiments in history, Nobel-prize-winning physicist Rainer Weiss’s path to success is remarkable. Now aged 90 he ...
