Which of the following statements is not true about the Big Bang Theory?

• At first, our universe was in a hot and extremely dense state.

• Then, it exploded and created space (tér), energy, matter and time.

• As the radiation from the explosion decreased, the first atoms were formed, mostly carbon and iron.

• Atoms formed atomic clouds, and the gas within them had enough gravity to cause more atoms to collect. They will form the core of stars.
