BLACK HOLE Meaning and
Definition
-
A black hole is a region in space from which nothing, not even light, can escape due to the immense gravitational pull created by the collapse of a massive star. In simpler terms, it is a celestial object that possesses an incredibly strong gravitational field that no particles or electromagnetic radiation can break free from its grasp.
Black holes are formed when a massive star exhausts its nuclear fuel and collapses under its own gravity. As the star collapses, it becomes extremely dense and its mass is concentrated in an infinitesimally small point known as a singularity. Surrounding this singularity is a region called the event horizon, which defines the point of no return. Anything crossing this boundary is irreversibly drawn into the black hole, and even light is unable to escape its gravitational grip.
Due to their invisible nature and the inability to directly observe them, the study of black holes relies on observing the effects they have on surrounding matter and the distortion they cause in the fabric of space-time. They have a profound impact on the evolution of galaxies, as their gravitational pull affects the movement of stars and gas around them.
Black holes are classified into different types based on their mass. Stellar black holes are formed from the remnants of massive stars and typically have masses ranging from a few times that of our Sun to tens of times larger. Supermassive black holes, on the other hand, have masses equivalent to millions or even billions of solar masses and reside at the centers of galaxies, including our own Milky Way.
The study of black holes continues to fuel scientific curiosity and exploration, as they are enigmatic and powerful objects that challenge our understanding of the laws of physics and the nature of the universe.

Etymology of BLACK HOLE
The term "black hole" was coined in 1967 by the American physicist, John A. Wheeler. However, the concept of a black hole and its properties predates this term. The theoretical notion of an object from which nothing, not even light, can escape was proposed by the British geologist and physicist, John Michell, in a 1783 letter to the Royal Society. The term "black hole" was later introduced to describe such an object. The word "black" refers to the fact that no light can be emitted from or reflected off the object, making it appear black. The term "hole" suggests that it is a place in space where objects can potentially disappear or be trapped forever due to the extreme gravitational pull.

black hole
A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. This term is often used metaphorically to describe a situation or place that seems to consume or trap things without letting them escape.
