History of the Universe
The big bang is a vital scientific theory about the origin of the universe. It occurred about 15 to 18 billion years ago. It marked the instantaneous creation of all matter in the universe. The explosion that took place was not a normal explosion; starting as a point of infinite density, thus called the “primordial nucleus”. It expanded at speeds equal to and even greater then light.
However, according to the Big Bang theory, the universe will continue to expand for billions of years. The galaxies do not expand. The galaxies will get farther apart and farther apart as time moves on. All forms of matter were formed during this time period. This theory impacted the scientific world and still is an integral part of the scientific world and in the formation of the universe. According to the Big Bang theory the universe should consist of approximately seventy to five percent of hydrogen and twenty-five percent of helium. The universe for a short yet brief time was stuck in a false vacuum. Then it from the state of being a false vacuum to a true vacuum, the state the universe is in today.
