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:

The Big Bang theory posits that the universe began in an extremely hot and dense state, and it was also very tiny (compact) initially. The evidence supporting the Big Bang (like cosmic microwave background radiation, etc.) aligns with the universe being extremely hot and very tiny (compact) at its start. The option "It was composed of ice" is incorrect as the early universe was hot and dense, not icy. "It was contracting" is also incorrect as the universe is expanding, and the Big Bang implies an initial expansion from a tiny, hot state. So the two correct answers are the ones about being extremely hot and very tiny.

Answer:

• It was extremely hot
• It was very tiny
