black holes - Nasa Theory
In the vast expanse of the cosmos, there exist enigmatic phenomena that challenge our understanding of the universe. Among these cosmic mysteries, black holes stand out as some of the most captivating and perplexing objects known to humanity. The theory of black holes, born out of the profound insights of theoretical physics, continues to captivate scientists and enthusiasts alike, offering a glimpse into the fundamental nature of space, time, and gravity. A Conceptual Overview: At its core, a black hole is a region of space where gravity is so intense that nothing, not even light, can escape its grasp. The concept of a black hole arises from the general theory of relativity proposed by Albert Einstein in 1915. According to this theory, massive objects warp the fabric of space-time, creating gravitational fields that dictate the motion of other objects nearby. When a massive star exhausts its nuclear fuel and collapses under its own gravity, it may give rise to a black hole. The ...
