How and When did the Universe Start? - Geography for Kids | Educational Videos by Mocomi

https://mocomi.com presents - How and When did the Universe Form? Watch this video to understand how the universe was formed. What materials it was made of, and how it has changed over several thousand years. Astronomers are scientists who study the universe. Many of them believe that the universe began about 15 billion years ago. They think that at first the universe was very, very small and made from completely different materials than it is today. Soon after it began, the universe started to spread out very rapidly. This growth is now called the Big Bang because it was so fast it was like an explosion. Before the Big Bang, the universe was the size of a pinhead. Then it expanded so rapidly that it was like an explosion. There was a great flash of light and intense heat of billions and billions degrees Celsius. There is nothing in the universe today that is as hot as that. After the Big Bang, the universe continued to spread out and cool slowly. At first, it seemed a hazy mass. As time passed, gases began to form and parts of the universe became clearer As the universe kept spreading out, gases came together to form huge clouds known as proto-galaxies. The proto-galaxies eventually gave birth to stars. Stars, gas and dust came together to form groups called galaxies. Galaxies can contain billions of stars. Today, the universe is made up of billions of galaxies.
