Explanation / Answer
his video is prominently about how the solar system is ormed.
our solar system is a collection sun , planets , moons revolving around planets , a vast majority of asteroids scattered all over and all of them revolving around the sun bound by gravity .Thers is a pattern in sizes of the planets around the sun . The First four planets mercury , venus , earth and mars are relatively smaller than the outer four planets jupitor, staurn uranus and neptune . Between the mars and jupitor there is a asteroid belt consisting of billions of rocks and asteroids. Beyond the orbit of neptune there is a collection of rocky ice balls called KOI-per belt whisc revolves in the same plane in which planets do. But if we go further tens of billions of kilometres away from the sun we see that a huge spherical cloud is merged with KOIper belt revolving all over.This cloud is called oort cloud.
This will lead to the answer how our solar system might have formed 4.6 billions years ago. A huge gas floating in the space which is in balance by its gravity counteracted by the internal heat . But somehow due to near by star explosion or cloud collision its bance got upset and gravity took over making the gas cloud to collapse into itself.Due to decrease in the size of the cloud itsangular momentum increased rapidly flattening out the cloud into a disk. As the gases collapsed into itself getting very dense and hot and at far outward in the disk matter got rammmed into each other and groing in size .eventually their gravity increased drawing in more matter and finally forming planetesimals or planets .
As the planets are formed same happened at the ntre of the disk where the matter is so dense and hot forming a protostar or proto sun . Its core got so hot that hydrogen and helium fused together releasing a huge amount of energy forming sun blasting out huge amount heat and light over millions of years blewing away the left over matter which did not merge together . Thus our solar system is formed.
Our solar system is not only the one but one in a million solar system forming daily out in the universe.
