The Birth of The Universe

Have you ever wondered how you were born? Maybe you wonder how the Earth was born or even how the universe was born. Today, we will answer one of those questions, the birth of the universe. The universe once didn’t exist. Then it came into life and started expanding. This was called the Big Bang. The Big Bang hit the hottest temperature. After a tiny fraction of a second after the explosion, the heat was one quadrillion Celsius. To this day, it’s still expanding. The universe is 13.8 billion years old. Eventually, substances like hydrogen and other things started to form atoms and then planets, stars, and so on. Have you ever thought a galaxy is enormous? If you put all the galaxies, planets, stars, clouds, black holes, and other things made out of matter together you get 4% of the universe. About 30% of the universe is dark matter and about 70% of the universe is dark energy. How do you think the universe would end.
