The symphonies registered by the wave detectors were produced during the collision that created the black holes, according to ...
A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...
Gravitational wave detectors on Earth have heard the "cry" of two newborn black holes with some unusual and remarkable ...
Scientists are still hunting for the source of the faint, persistent hum of gravitational waves discovered reverberating through the Milky Way last year. Those waves could point to more than one ...
Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...
Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...
Thanks to a theory put forward by Albert Einstein over 100 years ago and a happy coincidence, astronomers have discovered radiation being pumped out from the core of a quasar — within which a ...
