Which is evidence of universe expansion that supports the Big Bang Theory? (1 point)
• The temperature of the universe has cooled over time.
• The temperature of the universe has warmed over time.
• The temperature of the universe has cooled and warmed repeatedly over time.
• The temperature of the universe is the same as it was at the time of the Big Bang
The option that is evidence of universe expansion that supports the Big Bang Theory is: The temperature of the universe has cooled over time.
The correct answer is: The temperature of the universe has cooled over time.
To determine the evidence of universe expansion that supports the Big Bang Theory, we need to assess the observed changes in the temperature of the universe over time.
The correct answer is:
• The temperature of the universe has cooled over time.
Explanation:
The Big Bang Theory proposes that the universe originated from a single, incredibly hot and dense point roughly 13.8 billion years ago. Following the Big Bang, the universe began expanding and cooling down. As the universe expanded, the energy and radiation within it spread out, resulting in a gradual decrease in temperature. This cooling process is one of the fundamental tenants of the Big Bang Theory.
To arrive at this answer, you should eliminate the other options:
• The temperature of the universe has warmed over time: This contradicts the theory's assertion that the universe has cooled down as a result of expansion.
• The temperature of the universe has cooled and warmed repeatedly over time: This option suggests a cyclical pattern of temperature changes. However, the Big Bang Theory posits a one-time event that initiated universe expansion, rather than a repeated process.
• The temperature of the universe is the same as it was at the time of the Big Bang: If the temperature remained unchanged, it would imply that no cooling had occurred, which is inconsistent with the Big Bang Theory.
In conclusion, the evidence that supports the Big Bang Theory is the observed cooling of the universe over time.
