Scientists have reported the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves. The waves oscillate very slowly over years and even decades and are thought to originate primarily from pairs of supermassive black hol
When an astronomer discovered a brief bolt of energy that could travel billions of light-years, he was astonished. Then decades went by without evidence of another.
A 15-year collaboration in which Cornell astrophysicists have played leading roles has found the first evidence of gravitational waves slowly undulating through the galaxy, ripples in space-time likely generated by pairs of supermassive black holes i
A collaboration including Cornell astrophysicists has found the first evidence of low-frequency gravitational waves believed to be generated by merging pairs of supermassive black holes.
