\while the big bang theory is the most popular modern theory of how the universe formed, it is incomplete.\
(1 point)

the big bang theory does provide an explanation for the questions
, and

the big bang theory does not answer the question

what is the temperature of deep space? how did galaxies and stars form? when did the universe form?
what is the future of the universe?

Explanation:

To solve this, we analyze the Big Bang theory's scope:

• Questions the Big Bang theory explains:
• "What is the temperature of deep space?": The theory predicts the cosmic microwave background (CMB) temperature, so it explains this.
• "When did the universe form?": It provides a timeline for the universe’s origin (e.g., ~13.8 billion years ago).
• "How did galaxies and stars form?": It describes the early universe’s conditions (e.g., matter distribution) that led to galaxy/star formation.
• Question the Big Bang theory does not answer:
• "What is the future of the universe?": The theory focuses on the origin and early evolution, not the long - term future (e.g., whether it will expand forever, collapse, or reach a “heat death”).

Answer:

• The Big Bang theory does provide an explanation for the questions: "What is the temperature of deep space?", "When did the universe form?", and "How did galaxies and stars form?".
• The Big Bang theory does not answer the question: "What is the future of the universe?".
