What is the difference between the inner event horizon and outer event horizon?

Answer 1

• the event horizon is an imaginary spherical or ellipsoidal shell at a certain altitude above the singularity of the black hole, the shape and altitude above the singularity of this imaginary shell depends on only three properties of the singularity: mass, spin, and charge. the event horizon shell is not solid and so things fall through it quite easily, but nothing inside it can go outside it including light
• a black hole has no surface, only a singularity of infinite density at its center

Answer 2

The event horizon is the point of no return in black holes. After passing the point, light and matter cannot escape the massive gravitational pull of the black hole. The matter or light will then disappear. Matter and light *can* pass black holes, as long as the event horizon is avoided. The path of passing matter is affected and curved, though still able to pass safely.

However, if the Black Hole is spinning, this creates a region inside the Black Hole, beyond the Event Horizon called the Inner Horizon. Weirdly, according to Einstein's theory of General Relativity, it's not just light that can fall into a Black Hole, also space itself can fall in, like water falling over a Waterfall. Crucially, when it does this, it does so faster than the speed of light, meaning an object crossing the Event Horizon eventually gets pinned by centrifugal force caused by the black hole spinning at immense speed. Objects that have crossed the event horizon, can fall into the Black Hole's centre, known as the Singularity, however, largely, the Objects falling in get lifted out, back towards the Inner Horizon.


The Inner Horizon of a Black Hole is a very chaotic place, matter falling in to the black hole after crossing the Event Horizon, collides with matter being flung outwards by the centrifugal force caused by the Black Hole's rotation. When they do so they collide at stupendous energies, anything, or anyone who fell into a Black Hole would be vaporized at this point.

Answer 3

The inner event horizon is the boundary within a black hole beyond which events cannot affect an outside observer, while the outer event horizon is the boundary beyond which events cannot escape the black hole's pull. The inner horizon marks the point of no return for infalling objects, while the outer horizon defines the boundary of the black hole itself.

Answer 4

I would think so. An event horizon is the point at which nothing, not even light can escape the pull of a black hole.

Answer 5

nothing
