Listening for Gravitational Waves Using Pulsars

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...

NANOGrav hears “hum” of gravitational wave background, louder than expected

Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

Dr. Nergis Mavalvala Helped Detect the First Gravitational Wave. Her Work Doesn’t Stop There

These are the questions that Dr. Nergis Mavalvala asks about the universe. It’s not the meaning-of-life stuff in the traditional sense, but more of how everything around us came to be. These are the ...

Could Gravitational-Wave ‘Memories’ Prove Einstein Wrong?

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...
