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

If you’re concerned about getting every microsecond out of life, then you might not want to migrate to Mars. Using extremely ...

Aligarh, Dec. 29 -- day National Workshop titled"Introductory Workshop on General Relativity and Gravitation (IWGRG-2025)". Organized in collaboration with IUCAA, Pune, and supported by ANRF and CSIR.

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

ABSTRACT: An analysis of the Penrose-Carter diagram of the gravitational collapse of a thin shell of radiation in Minkowski spacetime supports the idea of a quantum origin of the event horizon, and ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...
