Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...
Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...
Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
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’ ...
Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).
Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.
