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 ...

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

The standard explanation has been dark energy, an invisible force added into the equations to make the math work. But now, an ...

If the universe was a soundtrack, we have been humming it our whole life. Every atom in our body, every star in the sky, every beam of light is part of a piece of music that never stops playing.

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, ...

1 / 6 | Each exact solution of the mathematical relations of general relativity (Q1) has a name. Name this person, who solved the relations for what space looks like around a spherical and ...
