Star Formation
Just wondering if anyone can give me a simple answer to the following question:
I have been reading, as novice, about how stars are believed to form when:
1. Gravity causes hydrogen gas to clump together, then
2. Over time the process "snowballs", until
3. Critical mass is reached, where the building heat and pressure within the growing ball of gas spontaneously initiates nuclear fushion, and
4. A star is born.
I also understand that the temperature of a star relates to its size when this first moment of spontaneous combustion occurs.
Does anyone know why all stars aren't exactly the same if this theory is correct, ie, wouldn't the critical moment of combustion occur as the same mass is reached for all stars if the constituent is always hydrogen? It is not as if there would be a significant influence from the surrounding material / conditions as we are talking about the expanses of the universe here!!
Looking forward to your thoughts....
