What IS the sun? I mean, WHY is it a ball of gas? How did that come about? Is there a solid center? How can a ball of gas retain a ball shape? How did the sun start?
Does anyone in the scientific community know the answers to these questions?
I thought it was made of green cheese, but I’m becoming less certain all the time.
The sun and stars began as clumps of hydrogen gas (which in turn was generated in the creation event) whose own gravity squeezed them together tightly enough to start nuclear fusion processes that turn the hydrogen into helium and release lots of energy. If this keeps up long enough the hydrogen is depleted and the helium starts getting squeezed together into heavier elements — it will be an extremely long time before the sun starts doing this, if it ever does. A symmetric globe is what you get when there is no other significant force affecting the star. Stars that spin rapidly enough become squatty ellipse shapes.
Yes

Yes. All of them. They're all part of basic science (physics).
