The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

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

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...

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

One hundred years ago, a gifted teacher of physics was born. He taught concepts of intricate General Relativity (GR) to his students using simple daily life examples. He was Amal Kumar Raychaudhuri, ...
