Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

This is a preview. Log in through your library . Abstract Time distributed order two-sided space differential equations of arbitrary order offer a robust approach to modelling complex dynamical ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

Wormholes are theoretical tunnels connecting distant points in space. They could potentially allow faster-than-light travel. Einstein's theory of relativity suggests wormholes might exist. Their ...

The additive Schwarz (AS) method was originally designed for preconditioning elliptic problems, and recently the method was extended successfully as a coupled space-time preconditioner for parabolic ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...
