A new paper from Stockholm University lays out an intriguing idea: What if the spontaneous radiation emitted by single atoms is actually affected by passing gravitational waves? And what if those effects could be read out to create a detection of the gravitational wave in question?Let’s go back to the …

Black holes can be perplexing and counterintuitive because they exist at the very edge of our current understanding of physics. Even as they’re warping the fabric of the universe, black holes have to obey certain rules. For the first time, we have direct confirmation of a vitally important property of …

Gravitational-wave detectors can be used to measure gravitational-field hair of extreme black holes, according to a paper published in the journal Physical Review D. Extreme Kerr black holes have gravitational hair that can be measured at finite distances and violates the uniqueness theorems. Image credit: Sci-News.com / Zdeněk Bardon / …

A team of theoretical physicists at the University of Basel, Switzerland, has found that in the very early Universe, so-called oscillons — strong localized fluctuations of the inflaton field — can act as ‘gravitational wave factories.’ According to Antusch et al, oscillons produced a characteristic peak in the otherwise broad …

An international team of scientists has identified a second gravitational wave event in the data from the twin detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This image depicts two black holes just moments before they collided and merged with each other, releasing energy in the form of gravitational waves. …
