Black Hole – What is Black Hole in Physics
Black Hole – A black hole is a solution to the equations of general relativity that represents a region of spacetime in which gravity is so intense that no physical signal, including light, can escape…

Detection of Black Hole
Black holes, once regarded as rare curiosities of physics, are now understood to be widespread features of the universe, with their frequency depending on their type and size. Stellar-mass black holes, the remnants of massive…

Gravitational Lensing by Black Hole
Gravitational lensing due to a black hole is a direct consequence of the curvature of spacetime predicted by Einstein’s general theory of relativity, in which gravity is not treated as a force acting at a…
-
Spaghettification by Black Hole
Spaghettification, a term coined to describe the extreme tidal stretching experienced by matter in the vicinity of a black hole, arises from the fundamental nature of gravitational fields in general relativity and their variation with…

Singularity of black hole
In the context of general relativity, the term “singularity” in a black hole refers to a region in spacetime where the curvature becomes unbounded and the classical description of gravity breaks down. The modern concept…

Existence of black hole
Black holes exist as a direct and unavoidable consequence of the fundamental structure of gravity as described by modern physics, particularly general relativity, combined with the properties of matter at extreme densities. Their existence is…

Types of Black Hole
Supermassive black holes are colossal gravitational engines located at the cores of most galaxies, including the Milky Way, which harbors one known as Sagittarius A*. Unlike the relatively small black holes formed from dying stars,…

Formation of Black Hole
Black holes are among the most extreme and fascinating objects in the universe, formed through the gravitational collapse of massive stars or the direct compression of dense cosmic matter. This article explores the physics behind…
-
Event Horizon of Black Hole
The event horizon of a black hole is best described as an invisible frontier in spacetime, beyond which escape becomes impossible, even for light itself. Unlike a tangible surface, it is a conceptual boundary where…

Interior of Black Hole
The question of what lies inside a black hole sits at the intersection of gravitation, quantum theory, and the philosophy of physical law. In classical general relativity, a black hole is not a material object…
