The picture above is an image that can help you to image what the Big Bang looked like. There was an abundance of energy released when the explosion occurred. The liquid-like splash that is radiating off in this picture is the energy that is being released.
The Big Bang Theory The Big Bang Theory is a long thought idea that tries to hypothesize the beginning of space and time. The idea of the Big Bang Theory is credited to Georges Lemaitre, a Belgian priest, astronomer, and teacher of physics.
According to research done by cosmologists, the universe is estimated to be 14 or 15 billion years old. At one point, there was only one compact bubble of matter that was intensely heated and overwhelmingly dense. All at once, it exploded. That explosion is known as the Big Bang. The Big Bang is thought of as the beginning of space and time.
As the universe expands, it cools as well. While the universe cools, matter and particles are created. Protons and neutrons, two particle types, came together and formed hydrogen and helium. After almost 300,000 years, the universe cooled enough that clouds began to form from the hydrogen and helium.
From here, the clouds collapse and form stars and planets, that ultimately form the billions of galaxies that make up out universe. The Big Bang Theory also suggests that the universe has continuously expanded since the beginning of space and time, and still is getting bigger today.
The video above explains the Big Bang discovery. Edwin Hubble also helped explain the Big Bang theory. Many things contributed to the discovery of the Big Bang Theory.
