Black Holes are fascinating yet mysterious cosmic objects scattered across the Universe. Unfortunately, we don’t know much about them, and we barely managed to snap a photo of one located in another galaxy.
But, what exactly are black holes?
Per definition, a black hole is an astronomical object with such a strong gravitational pull that nothing, not even light, can escape from it. The “surface” of a black hole, called the event horizon, defines the limit where the speed required to evade it exceeds the speed of light, which is the speed limit in the cosmos. As a result, matter and radiation are trapped and cannot get out.
