In a major scientific breakthrough, researchers have detected a persistent gravitational wave background — subtle ripples in ...

Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. On September 14, ...

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

The researchers are members of the LIGO–Virgo–KAGRA (LVK) collaboration, a global network of scientists detecting ...

S4, a $900-million cosmology experiment, would answer one of the greatest questions in physics. Instead it’s become another cautionary tale of pursuing big science amid shrinking budgets ...

Could it be that the universe’s first structures were born not from enigmatic inflaton fields, but from the echoes of ancient ...

In the year of quantum, university’s faculty and students continue to innovate bold new work in quantum computing, ...

Joseph Giaime, head of the observatory, joined Louisiana Considered to talk to us about the event’s significance, and how ...

The merger resulted in a combined black hole 225 times our sun’s mass, and challenges current astrophysical models of black ...

To study this merger, scientists had to use advanced models that account for how fast-spinning black holes behave—a ...

Scientists have developed a more precise method for analyzing gravitational waves, offering a sharper view into the ...

A record-breaking black hole collision has stunned scientists with its sheer scale and speed. Detected by the LIGO-Virgo-KAGRA observatories, the event merged two enormous black holes—each over 100 ...
