Size of a mountain
- C.
Size of the earth
- D.
Bigger than the sun
Correct Answer
A. Similar to a single atomExplanation
Primordial black holes are theoretical and are believed to be extremely small in size, similar to a single atom, and formed in the early universe. They remain unobserved to date.Rate this question:
-
- 4.
Which feature differentiates a rotating black hole from a non-rotating one?
- A.
Accretion Disk
- B.
Ergosphere
- C.
Singularity
- D.
Photon Sphere
Correct Answer
B. ErgospHereExplanation
Rotating black holes, also known as Kerr black holes, possess an ergosphere, a region where space itself is dragged along with the black hole's rotation, which has implications for nearby matter and energy.Rate this question:
-
- 5.
Supermassive black holes are typically found in:
- A.
Nebulae
- B.
Interstellar Medium
- C.
The centers of galaxies
- D.
White dwarfs
Correct Answer
C. The centers of galaxiesExplanation
Supermassive black holes are typically found in the centers of galaxies, including our Milky Way. They can have masses millions to billions of times that of the sun.Rate this question:
-
- 6.
Which of the following best describes the density inside the event horizon of a black hole?
- A.
Infinite density
- B.
Zero density
- C.
Equal to neutron star
- D.
Same as Earth's core
Correct Answer
A. Infinite densityExplanation
Inside the event horizon of a black hole, the density is theoretically infinite due to the intense gravitational forces, which implies that the laws of physics as we know them break down in this region.Rate this question:
-
- 7.
What type of black hole is hypothesized to exist but has not yet been observed?
- A.
Primordial Black Hole
- B.
Micro Black Hole
- C.
Intermediate Black Hole
- D.
Reissner-Nordström Black Hole
Correct Answer
A. Primordial Black HoleExplanation
Primordial black holes are theoretical and remain unobserved. They are thought to differ from other black holes because they formed shortly after the Big Bang.Rate this question:
-
- 8.
Which of the following theories suggests that mini black holes formed soon after the Big Bang?
- A.
Quantum Loop Gravity
- B.
String Theory
- C.
Theory of Relativity
- D.
Hawking's Theory
Correct Answer
D. Hawking's TheoryExplanation
Hawking's Theory suggests that mini black holes could have formed shortly after the Big Bang due to quantum effects and rapidly evaporate through Hawking radiation.Rate this question:
-
- 9.
What is the name of the region around a black hole where escape is impossible due to the immense gravitational pull?
- A.
Ergosphere
- B.
Singularity
- C.
Accretion Disk
- D.
Event Horizon
Correct Answer
D. Event HorizonExplanation
The event horizon is the boundary surrounding a black hole where the escape velocity exceeds the speed of light, making it impossible to escape the immense gravitational pull.Rate this question:
-
- 10.
How are primordial black holes theoretically different from other types?
- A.
They don't rotate
- B.
Formed by the Big Bang
- C.
They have no event horizon
- D.
They emit visible light
Correct Answer
B. Formed by the Big BangExplanation
Primordial black holes theoretically differ from other black holes because they formed shortly after the Big Bang, likely at a different rate and scale.Rate this question:
-
- 11.
Theoretical black holes with charge but no rotation are known as:
- A.
Schwarzschild Black Holes
- B.
Kerr Black Holes
- C.
Reissner-Nordström Black Holes
- D.
Charged Stellar Black Holes
Correct Answer
C. Reissner-Nordström Black HolesExplanation
Black holes with charge but no rotation are known as Reissner-Nordström Black Holes. Electric charge affects the black hole's structure and properties.Rate this question:
-
- 12.
Black holes that don't rotate and have no electric charge are best described by:
- A.
Schwarzschild's solution
- B.
Kerr's solution
- C.
Reissner-Nordström solution
- D.
Newman's solution
Correct Answer
A. Schwarzschild's solutionExplanation
Black holes that don't rotate and have no electric charge are best described by Schwarzschild's solution. They have a singularity at the center.Rate this question:
-
- 13.
When black holes consume matter, what is often observed at their poles?
- A.
Gamma-ray bursts
- B.
X-ray emission
- C.
Pulsar-like pulses
- D.
