How did the universe look like before the Big Bang?
That's interesting. What about after the Big Bang?
After the Big Bang, the universe was incredibly hot and dense. In fact, it was so hot that subatomic particles couldn't form until the universe cooled down. As it cooled, particles began to form and expand outward, eventually leading to the formation of stars, galaxies, and the universe we know today.
