Black Hole Facts: Trivia Questions - Quiz

2.

What year did Albert Einstein first predict the ‘black hole’ term?
- 1920
- 1915
- 1916
- 1930
Correct Answer

A. 1916

Explanation

In 1916, Albert Einstein first predicted the term "black hole." This suggests that he proposed the existence of these astronomical objects or phenomena in that year.

What year was the first black hole discovered?
- 1981
- 1991
- 1961
- 1971
Correct Answer

A. 1971

Explanation

In 1971, the first black hole was discovered.

Which of these is known as a small but deadly black hole?
- Supermassive black hole
- Intermediate black hole
- Stellar black hole
- Strange black
Correct Answer

A. Stellar black hole

Explanation

A stellar black hole is known as a small but deadly black hole because it is formed from the collapse of a massive star. It has a mass ranging from a few times the mass of the Sun to about 20 times the mass of the Sun. Despite its relatively small size, a stellar black hole has an incredibly strong gravitational pull, which makes it deadly. Anything that gets too close to a stellar black hole, including light, cannot escape its gravitational pull and is pulled into the black hole, making it a dangerous object in space.

6.

When a large star collapses, it continues to compress and creates?
- Supermassive black hole
- Intermediate black hole
- Stellar black hole
- Strange black hole
Correct Answer

A. Stellar black hole

Explanation

When a large star collapses, it continues to compress and creates a stellar black hole. A stellar black hole is formed when the core of a massive star collapses under its own gravity, causing it to become extremely dense and creating a region of spacetime with a gravitational pull so strong that nothing, not even light, can escape from it. These black holes have a mass several times greater than that of our Sun and are formed from the remnants of massive stars that have exhausted their nuclear fuel.

Who discovered the first modern solution of general relativity that characterize a black hole?
- Karl Max
- John Loch
- Greenweather Johnson
- Karl Schwarzschild
Correct Answer

A. Karl Schwarzschild

Explanation

Karl Schwarzschild is credited with discovering the first modern solution of general relativity that characterizes a black hole. His solution, known as the Schwarzschild metric, describes the geometry of spacetime around a non-rotating black hole. This solution provided a mathematical description of the event horizon and singularity, which are key features of black holes. Schwarzschild's work laid the foundation for further research and understanding of black holes in the field of astrophysics.

8.

What year did a first publication interpret black hole as a region of space?
- 1958
- 1960
- 1962
- 1964
Correct Answer

A. 1958

Explanation

In 1958, the first publication interpreted a black hole as a region of space.

Rate this question:
9.

Which of these terms were used in describing the black hole previously?
- Blue star
- Dark star
- Black star
- Dark hole
Correct Answer

A. Dark star

Explanation

The term "Dark star" was used previously to describe a black hole. This term refers to the idea that a black hole is a celestial object that emits no visible light and appears dark in space. The concept of a dark star was used before the term "black hole" was coined to describe these mysterious objects with intense gravitational pull.

10.

How many independent physical properties is the black hole known to possess?
- 9
- 5
- 3
- 7
Correct Answer

A. 3

Explanation

Black holes are known to possess three independent physical properties. These properties are mass, electric charge, and angular momentum. Mass refers to the amount of matter contained within the black hole. Electric charge represents the electrical property of the black hole. Angular momentum refers to the rotational motion of the black hole. These three properties are used to describe and classify black holes in terms of their characteristics and behavior.
