Scientific Information on how stars were created (Special Adult Post)

Hi guys!

This pack of information you may not understand because it has scientific language and vocabulary. But mainly, parents and adults, this is especially for you to look at.

The first stars were created by the coalescing of hydrogen and a few other elements into large clouds. As these clouds became more massive the gravity they exerted began to squeeze these clouds into spheres. As this occured temperatures began to rise inside them. The denser they got the more matter was drawn into them, the larger they became, the more gravity they exerted, the hotter they got, etc. until the density became so great that the cores ignited and became self sustaining nuclear furnaces. These early stars had a relatively short life span compared to modern stars. As they burned up all their fuel they created heavier elements. When these stars finally used up all their fuel they exploded (nova) and seeded the cosmos with newer, heavier elements, such as helium, argon, oxygen, iron, etc. These elemnts , in turn, coalesced into new stars and repeated the process. Each new generation of stars was responsible for creating new elements. Every time a star goes nova it releases all these newer, heavier elements that make up everything in the known universe. Every thing that you are, every atom of everything on this planet and else where was born in the furnace of a star! We are all, literally, star children.

We got this information from Yahoo answers. They really do have good information there!
