Ooooh, This is fun question. I studied astrophysics and planetary sciences at University, I find this stuff really interesting. So by the world I guess you mean the Earth not the entire universe. As I’m not an astrophysicist though have a look at this video
The first image you see “the pillars of creation” is one of the most famous images in physics. Pretty amazing to think that Planetary and star formation occurs because of dust crashing into each other.
