The Solar Nebula Theory

How does this theory work?

The Solar Nebula Theory: Explained.

In the 18th century, three scientists, Emanuel Swedenborg, Immanuel Kant, and Pierce-Simon Laplace, started to develop how the Earth was created, this was when Kent, suggested that nebulae collapsed and flattened which formed stars and planets. Laplace argued that a nebular cloud decreased then cooled which flattened layers, collapsing them, which formed the planets. When these scientists tried to create models to show they were correct, they failed, until the 20th century, when an astronomer, Victor Safronov created a Solar Nebular Disk Model.

In the Model, a small molecular cloud was caught in a gravitational collapse, the collapsing mass collected into the center, which created the sun, when the rest of the mass tried to flatten into a disk, which the rest of the mass created everything else, from meteors to planets and asteroids.

I don't get it, what does this exactly mean?

Well, we can compare these masses to red food dye, if you take water and red food dye and put a few drops inside the water, the food dye has a greater mass and sinks to the bottom. If these liquids were a little more slower and more solid, the heavier mass will sink to the bottom, and the lighter masses float up to the top of the star/planet, to find out more about this theory, check out the site below!
