Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse under their own gravity, creating an incredibly dense core. Scientists use telescopes like the Event Horizon Telescope to study these mysterious objects.
Some black holes are supermassive, sitting at the centers of galaxies and influencing their structure. They can warp time and space, as predicted by Einstein's theory of relativity. Understanding black holes helps astronomers uncover secrets about the universe's formation and evolution.
