Question

origins of the universe quick check what does the evidence supporting the big bang theory assume about the universe when it began? select the two correct answers. (1 point) ☐ it was composed of ice ☐ it was extremely hot ☐ it was very tiny ☐ it was contracting

Explanation:

To solve this, we analyze the Big Bang theory's assumptions about the early universe:

• "It was composed of ice" is incorrect as the early universe was hot and dense, not icy.
• "It was extremely hot" is correct. The Big Bang theory posits the universe started in a very hot, dense state.
• "It was very tiny" is correct. The universe is thought to have begun as an extremely small, dense singularity before expanding.
• "It was contracting" is incorrect; the universe is expanding, and the Big Bang theory describes an initial expansion from a singularity, not contraction.

Answer:

B. It was extremely hot, C. It was very tiny
