Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

For more than a century, gravity has been the immovable backdrop of modern physics, a force that can be described and ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

The two stars in the nearby system ZTF J2130 are spiraling toward a catastrophic supernova. In the meantime, scientists are using the pair's slow orbital decay to put Einstein's theory of gravity to ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...
