Black holes are stellar objects which?

Black holes are among the most extreme and fascinating objects in the entire universe — regions of space where gravity has become so overwhelmingly powerful that nothing, not even light itself, can escape. They form when a massive star collapses under its own gravity at the end of its life, compressing an enormous amount of mass into an incredibly small point called a singularity. The gravitational field around a black hole is so intense that it warps space and time itself, creating what scientists call a spacetime curvature — one of the most dramatic predictions of Einstein's General Theory of Relativity.

• Event Horizon: The boundary around a black hole beyond which nothing can escape — not even light — marking the point of no return
• Singularity: The central point of a black hole where density becomes infinite and known laws of physics break down completely
• Formation: Black holes typically form when massive stars (at least 20 times the Sun's mass) exhaust their nuclear fuel and collapse
• Gravitational Intensity: A stellar black hole can have gravity billions of times stronger than Earth's gravity
• Einstein's Prediction: Black holes were theoretically predicted by Einstein's General Theory of Relativity in 1915, long before they were observed
