When did the big bang happen:

The big bang happened 13.7 billion years ago. The universe was just as small as an atom back then. It experienced a big explosion then grew larger and larger into the universe we see today. All the molten rock that had been blown up in the explosion slowly stuck together and formed the Sun, along with all the planets, including Earth.

How it all started:

Have you ever wondered how the Big Bang theory actually started? Well, it started as a small atom and doubled its size. In 10–34 seconds it grew and grew over the years and became the universe we live in today. Surprisingly, a small atom turned into a humongous universe that is the home to 390,900 planets and scientists are yet to discover more.

There was more than just one bang

We all know that there are thousands of universes in the galaxy, maybe even infinite! Roughly about 10,000 galaxies are visible, but scientists think we are yet to discover millions more. And honestly, I don’t think it's just a million, I think there is a centillion more which is 1 followed by 303 zeros, in short, it's a lot.

Was it really the Big Bang that made the universe?

The Big Bang Theory is just a theory. We really don’t know how it all started. It may just be God who made the universe but we are not 100 percent sure yet. Future technology may guide us to the real truth of how the universe was made. Maybe it was already pretty big before the explosion, we don’t know, but maybe just maybe the theory is right.

How did the bang happen?

There isn’t really a scientific theory of how the bang happened all we know so far is that there was a bang. Some argue that the Big Bang originated from the Big Crunch and that we are in a loop where this universe will end in another Big Crunch, leading to another Big Bang. It may have happened from all the pressure inside of the atom, however, I’m not sure after all I am just a nine-year-old girl.
