The area surrounding a black hole is called the event horizon. Any object that gets caught in the event horizon will never return. All black holes have an event horizon. Black holes that have a charge and a spin, will generally have an inner horizon (coinciding to the outer horizon, the event horizon). At the inner horizon, matter is infinitely compressed and then sucked into the singularity. Along with black holes are white holes (otherwise known as "anti-black holes"). White holes are the exact opposite of a black hole, instead of sucking and trapping matter to where it is lost from the universe, white holes spew out matter and return it to the universe. Most scientists agree that white holes don't exist in our universe because they are very unstable. If the white hole was able to exist at all, it would last for only a couple of milliseconds before evaporating. The main thing between a black hole and a white hole is that a white hole is the black hole in the future. Inside the inner horizon, something bizarre happens. Matter enters one of two very narrow laser like beams. One beam goes against the black hole's spin and has positive energy and moves forward in time, but here's the real brainteaser, matter that enters the beam moving WITH the black hole's spin moves backwards in time and has negative energy. These two beams are shot out of the black hole at either end at nearly the speed of light. The black hole is basically a giant particle accelerator. Now I was correct. When the black hole shoots out the two beams, it becomes the white hole from the distant future. The two are the same. Now I know you just wanted the answer to the event horizon, but I just wanted to share a little more knowledge.

What is the OUTSIDE of the black hole called?

The very outside part of a black hole when "feeding" is called the Accretion Disc. when a black hole is not devouring a star the outside part becomes the Event Horizon.


What is the brilliant light coming from a black hole?

if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.


What is the area surrounding a black hole named?

It is called the "accretion disk". However, you are probably looking for "The Event Horizon".


A collapsed star from which light cannot escape?

A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.


What are the effects of black hole on other planets?

As the planet is approaching a black hole due to the immense gravitational pull on the objects surrounding it, the planet revolves around the black hole until it falls into the black hole.


What is the radius of a black hole singularity?

If it had a radius, then it wouldn't be a singularity. The event-horizon surrounding a black hole has a radius, which depends on the black hole's mass. But the singularity itself has no radius.


Why is a black hole a thery not a fact?

there is secondary evidence of a black hole. there is only secondary, because a black hole can be detected by its surrounding, such as the radiation an object gives off as it is being sucked in.


What happens inside of a black hole and how does it affect the surrounding space-time?

Inside a black hole, matter is crushed to a point of infinite density called a singularity. The intense gravitational pull of a black hole warps space-time, causing it to curve inwards. This affects the surrounding space-time by distorting the fabric of the universe and trapping anything that gets too close, including light.


How do yo you know there is a black hole in space when space is black?

The black hole itself cannot be seen, however, its pulling effects of the surrounding area can be seen.


How big are and how do black holes on this galaxy effect their surrounding?

Black hole has very strong gravitional force thats why if any things near from this black hole swalled this


Do black holes spin, and if so, how does their rotation affect their properties and interactions with surrounding matter?

Yes, black holes can spin. The rotation of a black hole affects its properties by creating a region called the ergosphere, where objects can be dragged along with the black hole's rotation. This spinning motion can also influence how black holes interact with surrounding matter, such as causing the formation of accretion disks and jets of high-energy particles.


What is an event horizan?

An event horizon is a boundary surrounding a black hole beyond which nothing, not even light, can escape due to the immense gravitational pull. It marks the point of no return for any object that crosses it, effectively trapping everything within the black hole.
