What is a black hole?
-
A region of spacetime where gravity is so strong that nothing, not even light, can escape.
-
A region of spacetime where gravity is so weak that nothing, not even light, can escape.
-
A region of spacetime where gravity is so strong that everything, even light, can escape.
-
A region of spacetime where gravity is so weak that everything, even light, can escape.
A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape. This is because the escape velocity from a black hole is greater than the speed of light.
What is the event horizon of a black hole?
-
The boundary beyond which nothing, not even light, can escape from a black hole.
-
The boundary beyond which everything, even light, can escape from a black hole.
-
The boundary beyond which nothing, not even light, can enter a black hole.
-
The boundary beyond which everything, even light, can enter a black hole.
The event horizon of a black hole is the boundary beyond which nothing, not even light, can escape from a black hole. This is because the escape velocity from a black hole is greater than the speed of light.
What is the singularity of a black hole?
-
The point at the center of a black hole where all of the mass of the black hole is concentrated.
-
The point at the center of a black hole where all of the energy of the black hole is concentrated.
-
The point at the center of a black hole where all of the momentum of the black hole is concentrated.
-
The point at the center of a black hole where all of the angular momentum of the black hole is concentrated.
The singularity of a black hole is the point at the center of a black hole where all of the mass of the black hole is concentrated. This is a point of infinite density and infinite curvature.
What is the Penrose diagram of a black hole?
-
A diagram that represents the spacetime of a black hole.
-
A diagram that represents the event horizon of a black hole.
-
A diagram that represents the singularity of a black hole.
-
A diagram that represents the escape velocity from a black hole.
The Penrose diagram of a black hole is a diagram that represents the spacetime of a black hole. It is a two-dimensional diagram that shows the causal structure of spacetime.
What is the causal structure of spacetime?
-
The set of all possible paths that particles can take through spacetime.
-
The set of all possible paths that light can take through spacetime.
-
The set of all possible paths that information can take through spacetime.
-
The set of all possible paths that energy can take through spacetime.
The causal structure of spacetime is the set of all possible paths that particles can take through spacetime. It is a fundamental property of spacetime that determines how particles can interact with each other.
What is the relationship between the event horizon and the singularity of a black hole?
-
The event horizon is the boundary beyond which nothing, not even light, can escape from a black hole, while the singularity is the point at the center of a black hole where all of the mass of the black hole is concentrated.
-
