- Kant's NebularTheory
- The core of this cloud grew under the influence of gravity, becoming denser and hotter...
- ...and as material fell into the core, the cloud's rotation increased in speed, causing it to become disk-shaped.
- Around 5 billion years ago, the solar system was thought to have been formed from a giant cloud of gas composed of gas and dust...
- Lighter materials were pushed away from the sun while heavy materials with high melting points remained near it. Dust and molten metals began to clump together in clusters forming rocks.
- As temperatures increased, there was enough energy to trigger a nuclear fusion in the core, becoming our sun!
- Gravity made these rocks clump to each other, until they become big enough to become planets.
