A black hole is a region of space with an extremely strong gravitational pull, so strong that nothing, not even light, can escape from it.
Black holes are formed when a massive star dies and collapses under its own gravity, causing all of its mass to be concentrated in a single point.
When a black hole takes in photons, they will be pulled into the black hole and cannot escape. This is because the gravitational pull of the black hole is so strong that it bends the path of the photons towards the black hole.
No, nothing can escape from a black hole once it has passed the event horizon, which is the point of no return.
We can observe the effects of a black hole's gravitational pull on nearby objects, such as stars and gas clouds. Additionally, using advanced technology and mathematical models, scientists can make predictions about what happens to photons when they enter a black hole.
