A new theory suggests gravity could possibly be the result of entropy—which would mean everything in the universe would fall ...
Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...
In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...
A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...
Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...
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 ...
