Big bang theory
Süžeeskeem Tekst
- I wonder how the Earth was created.
- Some people believe it was created by the big bang theory. Let me tell you about it!
- Before the big bang the universe was inside a bubble that was smaller than a pinhead.
- When the universe exploded nearly 14 million years ago it created time, space and galaxies
- Seconds after the big bang particles began to form. These particles were called protons and neutrons
- These protons and neutrons began to form elements
- 300,000 years later the universe cooled down to form more chemical elements
- The first stars also began to form
- Earth was created with lots of rocks merging together. When the rocks collided it created lots of heat and when the outer layer of earth cooled down the heat got trapped inside!
- 10 billion years later the solar system and the sun were created
- Fact: The earths core is as warm as the sun!
- Oh wow! this was very interesting. Thank you for this information.
- There is one piece of evidence that supports the theory that is stars and galaxies are moving away from us which shows the universe was once trapped in a small bubble.
- The big bang theory is now widely used by the scientific community but there still isn't enough evidence to support the theory.
