The average temperature of the universe right now is about
(a) go down because of expansion.
(b) go down because space is very cold.
(c) remains constant because matter and energy cannot be destroyed.
(d) increase because of the gravitational attractions among superclusters.
The correct option for the statement “The average temperature of the universe right now is about
Answer to Problem 6RAT
The correct option for the statement “The average temperature of the universe right now is about
Explanation of Solution
In the initial stages of the universe just after the Big Bang, the temperature is billions of Kelvin. Since then the universe is expanding and hence cooling down.
Today the average temperature of the universe is
Conclusion:
Therefore, the correct option for the statement “The average temperature of the universe right now is about
