Directions: Read the passage and answer the question

In the realm of astrophysics, black holes stand as enigmatic cosmic entities. These regions of spacetime exhibit gravitational forces so intense that nothing, not even light, can escape their grasp. Their formation occurs from the remnants of massive stars that have undergone gravitational collapse.

 

The event horizon, an invisible boundary surrounding a black hole, is the point of no return. Once an object crosses this threshold, it is inexorably drawn towards the singularity—a point of infinite density—where the laws of physics as we understand them cease to apply.

 

Despite their formidable nature, black holes play a pivotal role in shaping the cosmos. They influence the dynamics of galaxies, sculpting the trajectories of stars and celestial objects in their vicinity. They are cosmic laboratories for the exploration of extreme conditions, providing insights into the nature of spacetime and the behaviour of matter under such immense gravitational forces.
