Question

What events led to the birth of the sun?

Answer 1

I tried this:

Explanation:

Consider that my explanation may be a bit "old" and that nowadays new discoveries and observation probably gave new insight into the process. Anyway, the way I studied it was the following.

In space we have the possibility to "concentrate" matter (hydrogen mainly) through the action of perturbations caused, for example, by the explosion of supernovae sending ripples of energy into empty space such as waves in the ocean.

These perturbations can cause the formation of (relatively) small centers of condensation where mass is denser and that rotate under the action of this action of aggregation. These nuclei start to have a significant gravitational pull attracting more mass and causing the nuclei to rotate more and attract more...stuff.

If they can attract enough material (hydrogen) the gravitational pull can cause the hydrogen atoms to get more and more packed up and if the quantity of material is sufficient to start thermonuclear fusion. Obviously this implies enormous pressure and heat but consider that the material forming these nuclei is a lot and the rotation produces enough friction to "ignite" the thermonuclear reaction.

This is the VERY simplified version of it....
