    What is a spherical boundary of zero thickness in which photons that move around black holes called? - ProProfs

    What is a spherical boundary of zero thickness in which photons that move around black holes called?

    • Photon sphere 

    • Zero spehere 

    • Karl's sphere 

    • Neutron sohere 

    Correct Answer
    A. Photon sphere 
    Explanation
    A spherical boundary of zero thickness in which photons move around black holes is called a Photon sphere.

    Which of these statements is wrong about the black hole? - ProProfs

    Which of these statements is wrong about the black hole?

    • It is a black body 

    • It has no mass 

    • It has no angual momentum 

    • It has no charge 

    Correct Answer
    A. It has no mass 
    Explanation
    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."

    When was the science of Hawking radiation explained? - ProProfs

    When was the science of Hawking radiation explained?

    • 1974 

    • 1966

    • 1991

    • 1937

    Correct Answer
    A. 1974 
    Explanation
    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.

    What is the most general black hole solution called? - ProProfs

    What is the most general black hole solution called?

    • Ker-Newman Metric 

    • Max units 

    • Planck units 

    • Newman metric 

    Correct Answer
    A. Ker-Newman Metric 
    Explanation
    The most general black hole solution is called the Ker-Newman Metric.

    Which of these radiations is used to study the black hole? - ProProfs

    Which of these radiations is used to study the black hole?

    • X-rays

    • Gamma ray

    • Beta rays 

    • Alpha ray 

    Correct Answer
    A. X-rays
    Explanation
    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.

    Who discovered the first strong candidate for a black hole? - ProProfs

    Who discovered the first strong candidate for a black hole?

    • Charles Darwin

    • Charles Bolton

    • Erwin Mark 

    • Joana Bolt 

    Correct Answer
    A. Charles Bolton
    Explanation
    Charles Bolton is credited with discovering the first strong candidate for a black hole.

    Which of these is not related to the science of black hole? - ProProfs

    Which of these is not related to the science of black hole?

    • Gravitational field 

    • Kepler law

    • Theory of relativity

    • Law of electrolysis 

    Correct Answer
    A. Law of electrolysis 
    Explanation
    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.

  • 9. 
    What are black holes with mass satisfying the Ker-Newman inequality called? - ProProfs

    What are black holes with mass satisfying the Ker-Newman inequality called?

    • Units 

    • Karls 

    • Extremal

    • Blackoles 

    Correct Answer
    A. Extremal
    Explanation
    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.

    What was the name of the first black hole that was directly photographed?  

    • Cygnus X-1

    • Sagittarius A*

    • M87*

    • V404 Cygni

    Correct Answer
    A. 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.
