The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Physicists are quietly advancing a radical idea: time might not be a single, thin line but a full three‑dimensional landscape ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Abstract: An algorithm is introduced for generating frequency selective surfaces (FSSs) capable of conforming to any curvature while maintaining the proper size, shape, and spacing of the elements.

Astronomers have directly observed a spinning black hole twisting spacetime, confirming a century-old prediction of ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Abstract: This letter introduces an innovative approach for image restoration. Our model is primarily motivated by the integration of curvature constraints into a self-supervised convolutional neural ...

We consider the thermodynamic properties of the constant curvature black hole solution recently found by Banados. We show that it is possible to compute the entropy and the quasilocal thermodynamics ...

Within the framework of general relativity, gravity is characterized as attractive. This characteristic is evident in the Raychaudhuri equation when the strong or weak energy conditions are satisfied.
