Question

what was the temperature of the universe after three minutes? *
absolute zero
exactly 3000 degrees
below 1 billion degrees celsius
room temperature

Explanation:

In the early universe, after about three minutes, the universe was still extremely hot but had cooled to below 1 billion degrees Celsius. Absolute zero is the lowest possible temperature and the universe was far from that state. Exactly 3000 degrees is too low for this stage, and room - temperature is also much too low.

Answer:

C. Below 1 billion degrees Celsius
