Question: What keeps stars such as the Sun from collapsing from their own self-gravity?
Possibilities:
- the centrifugal force created by rapid rotation
- the electrical repulsion of nuclei in the plasma
- the gravitational pull created by orbiting planets
- the outward pressure created by nuclear fusion
