Black Hole Questions and Answers
- 1.
Which of these is not related to the science of black hole?
- A.
Gravitational field
- B.
Kepler law
- C.
Theory of relativity
- D.
Law of electrolysis
Correct Answer
D. Law of electrolysisExplanation
This law pertains to the chemical process of electrolysis, which involves the movement of ions in a solution under the influence of an electric field and is unrelated to the physics of black holes.Rate this question:

Which of these statements is wrong about the black hole?
- A.
It is a black bodyÂ
- B.
It has no massÂ
- C.
It has no angual momentumÂ
- D.
It has no chargeÂ
Correct Answer
B. It has no massÂExplanation
The statement "It has no mass" is incorrect because black holes are formed from the collapse of massive stars, which means they have a significant amount of mass. Black holes have such strong gravitational pull that not even light can escape from them, making them appear "black."Rate this question:

What is the most general black hole solution called?
- A.
Ker-Newman MetricÂ
- B.
Max unitsÂ
- C.
Planck unitsÂ
- D.
Newman metricÂ
Correct Answer
A. Ker-Newman MetricÂExplanation
The most general black hole solution is called the Ker-Newman Metric.Rate this question:

What are black holes with mass satisfying the Ker-Newman inequality called?
- A.
UnitsÂ
- B.
KarlsÂ
- C.
Extremal
- D.
BlackolesÂ
Correct Answer
C. ExtremalExplanation
Black holes with mass satisfying the Ker-Newman inequality are called extremal black holes. The Ker-Newman inequality is a mathematical condition that relates the mass, charge, and angular momentum of a black hole. When a black hole's mass satisfies this inequality, it is considered extremal, meaning it has the maximum possible charge and angular momentum for a given mass. Extremal black holes are of interest in theoretical physics and provide insights into the properties and behavior of black holes.Rate this question:

What is a spherical boundary of zero thickness in which photons that move around black holes called?
- A.
Photon sphereÂ
- B.
Zero spehereÂ
- C.
Karl's sphereÂ
- D.
Neutron sohereÂ
Correct Answer
A. pHoton spHereÂExplanation
A spherical boundary of zero thickness in which photons move around black holes is called a Photon sphere.Rate this question:

When was the science of Hawking radiation explained?
- A.
1974Â
- B.
1966
- C.
1991
- D.
1937
Correct Answer
A. 1974ÂExplanation
In 1974, the science of Hawking radiation was explained. This theory was proposed by physicist Stephen Hawking, who suggested that black holes are not completely black, but instead emit small amounts of radiation due to quantum effects near the event horizon. This groundbreaking idea challenged previous understandings of black holes and had significant implications for our understanding of the universe.Rate this question:

Who discovered the first strong candidate for a black hole?
- A.
Charles Darwin
- B.
Charles Bolton
- C.
Erwin MarkÂ
- D.
Joana Bolt
Correct Answer
B. Charles BoltonExplanation
Charles Bolton is credited with discovering the first strong candidate for a black hole.Rate this question:

- 8.
Which of these scientists did not discover candidates for the black hole?
- A.
Isaac NewtonÂ
- B.
Charles BoltonÂ
- C.
Louis WebsterÂ
- D.
Paul MurdinÂ
Correct Answer
A. Isaac NewtonÂExplanation
Isaac Newton did not discover candidates for the black hole. Although Newton made significant contributions to the field of physics and astronomy, his work predates the discovery and understanding of black holes. It was not until the 20th century that scientists like Charles Bolton, Louis Webster, and Paul Murdin made advancements in the study of black holes.Rate this question:

- 9.
Which of these radiations is used to study the black hole?
- A.
X-rays
- B.
Gamma ray
- C.
Beta rays
- D.
Alpha ray
Correct Answer
A. X-raysExplanation
X-rays are used to study black holes because they can penetrate through the gas and dust surrounding the black hole, allowing scientists to observe the high-energy processes happening near the event horizon. X-ray telescopes in space, such as NASA's Chandra X-ray Observatory, are able to detect and analyze the X-ray emissions from black holes, providing valuable insights into their properties and behavior. Gamma rays, beta rays, and alpha rays are not commonly used for studying black holes as they have different characteristics and interactions with matter.Rate this question:

What was the name of the first black hole that was directly photographed?
- A.
Cygnus X-1
- B.
Sagittarius A*
- C.
M87*
- D.
V404 Cygni
Correct Answer
C. M87*Explanation
The first black hole that was directly photographed is known as M87*. This supermassive black hole is located at the center of the galaxy Messier 87 (M87), which is about 55 million light-years from Earth. In April 2019, the Event Horizon Telescope (EHT), a network of radio telescopes around the world, captured the first-ever image of a black hole's event horizon, showing the shadow of M87* surrounded by a bright ring of light.Rate this question:
