Текст на Статията
- The Sun
- The Big Bang theory suggests that the universe first began with a single dot known as the singularity. The singularity is known to be very small, smaller than a dot you draw from a pencil.
- The Singularity
- Planetoids and planets
- The beginning of the universe
- Many scientists believe that the singularity exploded but other scientists believe that it expanded, spreading space, time and many elements. Our universe has been expanding since it began.
- Nebula
- Approximately 5 billion years ago, the Nebula was created by a giant cloud of dust and gas.
- The beginning of Earth
- The giant dust and gas (Nebula) formed the sun by gravity, pulling all the gas to the centre which caused it to get very hot and dense.
- The planetoids were created by the remaining gas and particles that were drawn together by the gravity. These planetoids over time got bigger due to the colliding of debris and expansion of gas, which eventuallly formed the planets that we know.
- The evolution of multi-cellular organisms came into effect about 2 billion years ago. They evolved from single-celled organisms to plants and animals.
