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…

Black Hole
What is a 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,…

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…
