Understanding Time Dilation Near Black Holes

What is a black hole?

• A region in space with weak gravity

• A highly dense region in space with strong gravitational force

• A star that has exploded

• A planet with no atmosphere

According to Einstein's theory, how does time behave in a strong gravitational field?

• Time stops completely

• Time passes more slowly

• Time remains constant

• Time speeds up

What is the relationship between space and time according to Einstein?

• They are connected and form a fabric

• They are separate entities

• Space is a subset of time

• Time is a subset of space

How do massive objects like black holes affect space-time?

• They flatten it

• They have no effect

• They warp or bend it

• They create new space-time

In the analogy used, what happens to the distance between two points near a black hole?

• It becomes zero

• It decreases

• It remains the same

• It increases

Why does time appear to slow down near a black hole for a distant observer?

• Because the space-time fabric is warped, increasing the distance

• Because the black hole emits light

• Because the observer is closer to the black hole

• Because the observer is moving faster

What is the speed of light assumed to be in the analogy for easy understanding?

• 2 kilometers per hour

• 100 kilometers per hour

• 1.07 billion kilometers per hour

• 300,000 kilometers per second

What does general relativity explain gravity as?

• A force between two masses

• An electromagnetic force

• A chemical reaction

• A property of space-time

When was Einstein's theory of general relativity proposed?

• 1905

• 1916

• 1971

• 2000

When was the first black hole discovered?

• 1971

• 2000

• 1950

• 1916
