SCRIPT VERIFIED QUESTIONS AND
SOLUTIONS GRADED APLUS
●● What does the evolution of the universe signify for life on Earth?
Answer: The evolution of the universe has been directly responsible for
the presence of life on Earth today.
●● What is the significance of light travel time in astronomy?
Answer: Light from distant galaxies takes hundreds of millions of years
to reach Earth, affecting our understanding of the universe.
●● What is the role of observations in the scientific method?
Answer: Observations are the foundation for developing models and
hypotheses in science.
●● How did ancient astronomers model the universe?
Answer: They constructed models with Earth at the center, which were
later updated as new observations were made.
●● What is a hypothesis in scientific terms?
Answer: A proposed explanation that can be tested through experiments.
,●● What happens if experimental results contradict a hypothesis?
Answer: The hypothesis must be discarded and an alternative must be
developed.
●● What is dark energy?
Answer: A vast quantity of invisible energy that makes up the bulk of the
universe, still not fully understood by scientists.
●● What is the Crab Nebula?

●● What does the study of astronomy reveal about the cosmos?
Answer: It reveals the dynamic and evolving nature of the universe over
long periods of time.
●● What is the relationship between science and nature?
Answer: Science seeks to understand nature through observations,
experiments, and models.
●● What is the role of technology in modern astronomy?
Answer: Technology allows for deeper probing of the universe and the
testing of new hypotheses.
