    Which of the following theories best explains the presence of dark matter in the universe?

    • General Relativity

    • Quantum Mechanics

    • Big Bang Theory

    • Modified Newtonian Dynamics (MOND)

    Correct Answer
    A. Modified Newtonian Dynamics (MOND)
    Explanation
    Dark matter is a hypothetical form of matter that is thought to account for approximately 85% of the matter in the universe. While General Relativity and Quantum Mechanics provide frameworks for understanding gravity and particle physics respectively, and the Big Bang Theory explains the origin of the universe, they do not directly address the dark matter problem. Modified Newtonian Dynamics (MOND) is a hypothesis that proposes modifications to Newton's laws to account for the observed properties of galaxies without invoking dark matter. However, the existence of dark matter is still widely supported by observations such as galaxy rotation curves and gravitational lensing, and MOND remains a controversial and less accepted theory compared to the dark matter hypothesis.

    Is pluto a planet?

    • No

    • Yes

    • I dont know, no i guess

    Correct Answer
    A. No
    Explanation
    Pluto is not considered a planet because in 2006, the International Astronomical Union redefined the definition of a planet, and Pluto did not meet the new criteria. According to the new definition, a planet must orbit the sun, be spherical in shape, and have cleared its orbit of other debris. Pluto meets the first two criteria but fails the third one as it shares its orbit with other objects in the Kuiper Belt. Therefore, it is now classified as a dwarf planet.

    What really is a shooting star?

    • A shooting star is not actually a star, nor does it shoot. A shooting star is officially called a meteor

    • A star that falls on the ground

    Correct Answer
    A. A shooting star is not actually a star, nor does it shoot. A shooting star is officially called a meteor
    Explanation
    A shooting star is not actually a star because it is not a celestial body that undergoes nuclear fusion. It also does not shoot, as the term "shooting" is used metaphorically to describe its appearance as it streaks across the sky. Instead, a shooting star is officially called a meteor, which is a small piece of space debris that enters the Earth's atmosphere and burns up, creating a bright streak of light.

    Do you think that NASA will see if there is a another planet?

    • Yes

    • No

    • Maybe

    Correct Answer
    A. Maybe
    Explanation
    The answer "Maybe" suggests that it is uncertain whether NASA will explore the existence of another planet. It implies that there is a possibility that NASA might conduct investigations or missions to discover new planets, but it is not confirmed. The answer leaves room for both the possibility and uncertainty of NASA's actions in this regard.
