Gravitational wave detectors on Earth have heard the "cry" of two newborn black holes with some unusual and remarkable ...

The symphonies registered by the wave detectors were produced during the collision that created the black holes, according to ...

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 ...

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.

A pair of distant black hole mergers, measured just one month apart in late 2024, are improving how scientists understand the ...

Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe. “It’s super ...

Putting the squeeze on light improves gravitational wave observatories. An upgrade to one such observatory, LIGO, that comes from exploiting a quantum rule known as the Heisenberg uncertainty ...

The 2017 Nobel Prize in Physics has been awarded to three key players in the development and ultimate success of the Laser Interferometer Gravitational-wave Observatory (LIGO). One half of the prize ...

Physics World announced today that the 2016 Breakthrough of the Year goes to the LIGO Scientific Collaboration for “their revolutionary, first ever direct observations of gravitational waves.” LSU ...

NASA is live streaming a video of a spacewalk on its Facebook page, and you just might be able to catch it live from the International Space Station – or watch it again. The video shows astronauts ...

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 ...

What to do with an abandoned mine? “Turn it into a neutrino and dark-matter detector” is probably what most physicists would say. But we have lots of those already, so how about “A cosmic landscape ...
