What else can I help you with?
What is the name for the boundary around a black hole beyond which events cannot affect the observer?
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
Does a giant star have an event horizon?
No. An event horizon is an area where even light cant escape so only black holes have it
Can you watch objects being pulled past the event horizon of a black hole?
No, once an object crosses the event horizon of a black hole, it is no longer visible from outside the black hole. The gravitational pull is so intense that not even light can escape, making it impossible to observe objects beyond the event horizon.
What is the speed of light near to the event horizon of a Black hole?
The speed of light is a constant, it does not matter in or out of a black hole.
What is the difference between a black hole's photon sphere and its event horizon?
A black hole's photon sphere is the region around the black hole where photons can orbit in a stable circular path. The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole. In simpler terms, the photon sphere is where light can circle the black hole before falling in, while the event horizon marks the point of no return.
What planet has a event horizon?
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.

What is the event horizon in a black hole?
That is the "point of no return". Within the event horizon, gravity is so strong that anything that crosses the event horizon can't get out, even if it moves at the speed of light.
Can you watch objects being pulled past the event horizon of a black hole?
No, once an object crosses the event horizon of a black hole, it is no longer visible from outside the black hole. The gravitational pull is so intense that not even light can escape, making it impossible to observe objects beyond the event horizon.
Can a black hole be pink?
No, to be pink it would have to emit light and no light can escape a black hole's event horizon.
What is the speed of light near to the event horizon of a Black hole?
The speed of light is a constant, it does not matter in or out of a black hole.
How does the photon sphere of a black hole compare to its event horizon?
The photon sphere of a black hole is a region where light can orbit the black hole before being pulled in, while the event horizon is the point of no return where nothing, not even light, can escape the black hole's gravitational pull. The photon sphere is closer to the black hole than the event horizon.

The event horizon is the boundary beyond which nothing, not even light, can escape the gravitational pull of the black hole. In simpler terms, the photon sphere is where light can circle the black hole before falling in, while the event horizon marks the point of no return.
Does a black hole have an horizon?
The so-called "event horizon" of a black hole is the point-of-no-return. That means that anything that gets inside the event horizon can't get out any more, even if if it moves at the speed of light.
Why can't we see anything past the event horizon of a black hole?
The event horizon of a black hole is a boundary beyond which the gravitational pull is so strong that not even light can escape. This means that anything beyond the event horizon is invisible to us, as no light or information can reach us from that region.
Which of these have an event horizon giant black hole white dwarf neutron star?
A black hole has an event horizon, beyond which nothing can escape, including light. Neutron stars also have an event horizon, called the "surface" or "crust," which marks the boundary within which matter is crushed by extreme gravity. White dwarfs, being less massive, do not have an event horizon.
