In the star's center, the gas is so energized that it has become a sort of super gas, called plasma. The hot plasma is in constant motion. It expands like hot air inside a balloon and pushes outward from the center. Meanwhile, the crushing weight of the star material continues to press inward. In goes the outer material and out goes the inner. The plasma rolls and churns like a hyper hurricane of heat, light, sound, and motion. —A Black Hole Is NOT a Hole, Carolyn Cinami DeCristofano Which question would be a relevant to ask about this text? Why does the plasma in a star expand? Where can I take a hot-air balloon ride? Will there be a hurricane next week?
