The moments immediately after the universe began were in some ways similar the universe we see today. Which of these is the best answer? A. The universe was extremely hot after the bang and is still extremely hot today.
B. The universe began expanding with the Big Bang and it is still expanding today.
C. All the galaxies, nebulae, stars, and planets were created in the big bang and they are unchanged today.
D. The universe was lifeless then and it is lifeless now.

B. The universe began expanding with the Big Bang and it is still expanding today.

Explanation:

The universally accepted theory about how the universe came to be as it is now is the Big Bang theory, which describes how the universe expanded from an initial state of extremely high density and high temperature. As the universe kept expanding, it began to cool down. It is still expanding even now. New galaxies, nebulae, stars, and planets are born all the time, while old ones die. The universe is constantly changing and it is full of life.

This is why option B is the correct one.
