How was the world created according to science?

Question

Josiah Adams · Accepted Answer

The Earth and other planets were formed from dust particles clumping together.

Once the Sun was formed it was surrounded by a protoplanetary disk. This consists of dust, ices and gases. The gases tended to get blown towards the outer solar system by the solar wind. This is why the inner planets are rocky and the outer planets are gas giants. The dust and ice particles tend to collide due to the effects of gravity and also electrostatic charges. When they collide they clump together. Over time the clumps get bigger and fewer. Eventually the planet is formed and is effectively the only body in its orbit except for any moons. It is now thought that the Moon was formed when a planet the size of Mars hit the early Earth. The material ejected from the collision became the Moon.

undefined The Earth and the rest of the world were formed around 4.5 billion years ago by a process called accretion, which involved the slow build-up of gas and dust in the early solar system, which eventually came together to form planets, including Earth, around a young star called the Sun.
