What is the region of spacetime from which nothing, not even light, can escape?

  1. Event Horizon

  2. Singularity

  3. Black Hole

  4. Wormhole


Correct Option: A
Explanation:

The event horizon is the boundary in spacetime beyond which the gravitational pull of a black hole is so strong that nothing, not even light, can escape.

What is the point of no return within a black hole?

  1. Singularity

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: A
Explanation:

The singularity is the point of infinite density and gravity at the center of a black hole. Once an object passes the event horizon, it is inevitably drawn towards the singularity.

What is the name of the theoretical boundary surrounding a black hole, beyond which the laws of physics as we know them break down?

  1. Singularity

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: A
Explanation:

The singularity is the point of infinite density and gravity at the center of a black hole. It is a region where the laws of physics as we know them break down.

What is the name of the phenomenon that occurs when matter falls into a black hole and is compressed to an infinitely small point?

  1. Spaghettification

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: A
Explanation:

Spaghettification is the phenomenon that occurs when matter falls into a black hole and is compressed to an infinitely small point. This is due to the immense gravitational forces present near the singularity.

What is the name of the theoretical bridge between two different regions of spacetime?

  1. Singularity

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: D
Explanation:

A wormhole is a theoretical bridge between two different regions of spacetime. It is a hypothetical tunnel that connects two distant points in the universe.

What is the name of the region of spacetime around a black hole where the gravitational forces are so strong that light is bent and distorted?

  1. Singularity

  2. Event Horizon

  3. Ergosphere

  4. Wormhole


Correct Option: C
Explanation:

The ergosphere is the region of spacetime around a black hole where the gravitational forces are so strong that light is bent and distorted. It is located outside the event horizon.

What is the name of the hypothetical process by which a black hole can lose mass and energy over time?

  1. Hawking Radiation

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: A
Explanation:

Hawking radiation is the hypothetical process by which a black hole can lose mass and energy over time. It is caused by the creation and annihilation of virtual particles near the event horizon.

What is the name of the theoretical limit beyond which nothing can escape, not even light?

  1. Singularity

  2. Event Horizon

  3. Black Hole

  4. Wormhole


Correct Option: B
Explanation:

The event horizon is the theoretical limit beyond which nothing can escape, not even light. It is the boundary of a black hole.

What is the name of the hypothetical phenomenon that allows information to escape from a black hole?

  1. Wormhole

  2. Event Horizon

  3. Black Hole

  4. Hawking Radiation


Correct Option: D
Explanation:

Hawking radiation is the hypothetical phenomenon that allows information to escape from a black hole. It is caused by the creation and annihilation of virtual particles near the event horizon.

What is the name of the theoretical phenomenon that allows particles to tunnel through the event horizon of a black hole?

  1. Wormhole

  2. Event Horizon

  3. Black Hole

  4. Hawking Radiation


Correct Option: A
Explanation:

A wormhole is a theoretical phenomenon that allows particles to tunnel through the event horizon of a black hole. It is a hypothetical bridge between two different regions of spacetime.

What is the name of the hypothetical phenomenon that allows information to be transferred from one region of spacetime to another through a black hole?

  1. Wormhole

  2. Event Horizon

  3. Black Hole

  4. Hawking Radiation


Correct Option: A
Explanation:

A wormhole is a hypothetical phenomenon that allows information to be transferred from one region of spacetime to another through a black hole. It is a hypothetical bridge between two different regions of spacetime.
