What Is a Black Hole | Frenly Casino

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape, formed when a massive star collapses in on itself, as predicted by [[albert-einstein|Albert Einstein]]'s theory of [[general-relativity|general relativity]]. With a boundary called the event horizon, black holes are characterized by their incredibly strong gravity, which warps the fabric of spacetime, making them a fascinating topic of study in [[astrophysics|astrophysics]] and [[cosmology|cosmology]]. The concept of black holes has been around since the 18th century, but it wasn't until the 20th century that they were understood as regions of space from which nothing can escape, with [[stephen-hawking|Stephen Hawking]] making significant contributions to our understanding of these phenomena. Black holes come in various sizes, from small, stellar-mass black holes formed from the collapse of individual stars, to supermassive black holes found at the centers of galaxies, like the [[milky-way|Milky Way]].
