From lectures by Stephen Hawking to the letters of British politician Neil Kinnock – it's a race against time to save the ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...

Yes, there are aliens. No, we shouldn't contact them. Thus did world-renowned physicist Stephen Hawking crush the hearts of Trekkies and SETI-advocates everywhere. The Times of London got the quotes, ...

Stephen Hawking’s 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

Now, in the journal Physical Review Letters, researchers say their ability to analyze gravitational waves has improved so much over the past decade that they were recently able to verify a key idea ...

Theoretical physicist Stephen Hawking's public statements this year have been decidedly unusual, even weird. In April, he emphatically argued that humans should not try to contact aliens, for fear of ...

Discovery joins a list of the greatest hits of the LIGO detector, which ten years ago became the first to detect gravitational waves. The songs of the cosmos, now that we can finally hear them, might ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...

Scientists have used a gravitational wave detector to "hear" two black holes getting bigger as they merged into a single, gigantic entity. The detection, made by the Laser Interferometer Gravitational ...
