Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

In October 2024 the network detected a clear signal that pointed back to a merger that occurred 700 million light-years away. The progenitor black holes were 20 and 6 solar masses and the larger ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new details about how black holes form and spin.

New results from an international team including UBC astrophysicists highlight the first black hole observed to be spinning ...

Researchers detect the clearest black hole signal to date, enabling tests of Hawking's area theorem and advancing ...

LIGO is designed to detect gravitational waves, but it is also proving to be a fantastic laboratory for pushing the limits of quantum physics. Now, an international team of researchers has cooled the ...

Physicists have analyzed two enormous black hole mergers that happened one month apart and have come up with tantalizing ...

Earth is awash in gravitational waves. Over a six-month period, scientists captured a bounty of 39 sets of gravitational waves. The waves, which stretch and squeeze the fabric of spacetime, were ...

Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...

The 2017 Nobel Prize in Physics was awarded Tuesday morning to three pioneers of the Laser Interferometer Gravitational-wave Observatory, which announced last year the world's first direct detection ...
