When you think about black holes, what is the first thing that comes to your mind? The only thing that comes to my mind is “nothing”. I don’t mean the word, but the meaning, and I’ll explain why. A black hole, is a region of spacetime where gravity is so strong that no light, particles, or radiation can escape from it. A Black Hole is created through a Supernova. A Star has radiation, and when its radiation fuel starts to run out, some of the mass from the star flows into the core. Eventually, the core of the star becomes so heavy that it can’t withstand its own gravitational force. Then the core collapses and causes the star to explode. However, it first explodes and then implodes, meaning it first bursts outwards, and then the explosion is pulled to one specific spot. This is what causes a Black Hole.
The theory of general relativity predicts that a sufficiently compact mass is able to deform spacetime and form a black hole. The point of no escape in a black hole is called the event horizon. Even though this point can affect the fate and circumstances of an object that crosses it, or passes by, there is no detectable feature of this point which would help you find out where that point of no return is. When matter, which includes particles and atoms, falls into a black hole, the mass of the black hole increases. The event horizon is the point where the escape speed needed is faster than the speed of light. So in order to escape a black hole after reaching the event horizon, you would have to be going faster than the speed of light.
