Two amazing fact about event horizon in black hole in space?

1. The event horizon of a black hole is the point of no return, beyond which nothing, not even light, can escape the gravitational pull of the black hole. This makes it impossible to directly observe or study anything that falls beyond the event horizon.

2. The size of the event horizon of a black hole is directly related to its mass. The larger the mass of the black hole, the larger its event horizon will be. This means that the event horizon of a supermassive black hole, such as the one at the center of our galaxy, is much larger than that of a stellar-mass black hole.

1. Anything that crosses the event horizon, even light, cannot escape the black hole's gravity. This is because the gravity of a black hole is so strong that it bends spacetime so much that nothing can escape. Not even light can travel fast enough to escape the pull of a black hole's gravity.
2. The event horizon is not a physical surface. It is a mathematical boundary that marks the point of no return. Once something crosses the event horizon, it is forever trapped within the black hole. There is no way to escape a black hole once you have crossed the event horizon.
