You and a friend are looking at the stars and your friend says, "stars must be shrinking because gravity is constantly pulling their particles together." explain what is wrong with this reasoning.
answer within a paragraph. i promise you can't get it wrong. : )

 Technically? It's not wrong. A star is a ball of gas that is held together by it's own gravity of which it constantly struggles against. Gravity constantly works to try and make the star collapse. However, stars are extremely hot at their cores which help the star push against it's own gravity creating a sort of equilibrium. So long as the star continues to push against gravity, it will not collapse, however eventually a star will lose its energy and eventually collapse into a black hole.
