Today, we're exploring one of the universe's most intriguing phenomena: black holes. These cosmic enigmas are not just voids, but rather areas of intense gravitational force that nothing, not even light, can escape from. The theory of relativity predicts that black holes result from the collapse of massive stars, leaving behind a singularity where all matter is compressed to a dense core. Around the singularity, the event horizon marks the point of no return. Scientists use advanced telescopes to study these invisible objects, relying on the radiation emitted by material as it spirals into the black hole.
