How do black holes form?

Certainly! Black holes form from the remnants of very massive stars. When such a star runs out of fuel, it can no longer support itself against gravity. Without the outward pressure from nuclear reactions, the star’s core collapses under its own weight. If the core’s mass is large enough—typically several times the mass of our Sun—it shrinks down to an incredibly small, dense point called a singularity, surrounded by a boundary known as the event horizon. This event horizon marks the "point of no return," where the gravitational pull becomes so strong that not even light can escape. As for what happens to matter that falls into a black hole, it crosses the event horizon and gets pulled inexorably toward the singularity. From an outside observer’s perspective, the matter appears to slow down and fade as it approaches the event horizon due to extreme gravitational effects on light and time. However, from the falling matter’s point of view, it passes through the event horizon without noticing anything unusual and moves toward the singularity, where the laws of physics as we know them break down. Because no information can escape beyond the event horizon, black holes effectively trap matter and energy inside, making them some of the most mysterious and fascinating objects in the universe.
