Einstein’s version of dark energy is known as the cosmological constant. It implies a fixed amount of dark energy in each cubic meter of space; as the universe expands, more dark energy appears. So ...

How can we combat this kind of disinformation and restore public trust in elections? It might be possible to essentially "vaccinate" people against any viral post-election conspiracies that may emerge ...

A gravitational singularity refers to a point in spacetime where density and curvature become infinite, and the equations of general relativity no longer provide meaningful predictions. Theoretically, ...

Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks ...

Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with ...

Scientists propose that gravitational waves shaped the universe. Their model challenges inflation theory. How exactly did the universe start, and how did these processes determine its formation and ...

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

A researcher, Heikki Mäntysaari from the University of Jyväskylä (Finland), has been part of an international research group that has made significant advances in modeling heavy ion collisions. New ...

As they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field than sensors on the surface. They stay within a detectable proximity to ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein’s general ...
