You've probably heard of the big bang theory at some point. But do you know what it actually is? In The Big Bang Theory for Kids, you will learn what exactly this idea for how the universe began came to be in the first place. You will also learn a little about our own galaxy and solar system along the way.
The big bang theory was first suggested by a cosmologist and priest named Georges Lemaître in the 1920s. He estimates that the universe started out as a single atom at the beginning of time. Rather than by an explosion, the universe simply started to expand in a fraction of a second due to matter and energy. Over time, the expansion slowed, but Lemaître and many other scientists believe the universe is still expanding today.
The force of gravity plays a huge role in everything when it comes to the universe. All the objects in space form when particles and gases from the universe's expansion pull together (through gravity). When small amounts of dust and gas pull together, planets form and start to orbit the star. Another force called dark energy or dark matter is also important. We don't have a lot of information about it, but scientists think it's what causes cosmos apart faster and faster.
We hope you and your student(s) enjoyed learning about this cool idea! If you want to learn even more, head over to our website and download one of our many free lesson plans about the universe, full of activities, worksheets, and more!
