A recent line of inquiry explores how atomic systems behave when immersed in curved spacetime, particularly under the influence of gravitational waves. In a new study, scientists show that ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. Ever since astronomers announced ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Black holes may defy the famous “no-hair” theorem by leaking residual gravitational ripples that could one day be observed by gravitational-wave detectors. Such an observation would provide evidence ...

Fine balance The researchers measured the gravitational field between two gold masses of 1mm radius each that are brought close to each other. (Courtesy: Tobias Westphal, University of Vienna) ...
