Input: Consider Input: Stars burn mass. The star burns until it runs out of fuel. The star can no longer support its weight. The layers of hydrogen press down on the core.

Anything that gets close to it, is drawn into it by its gravity. Light is drawn into it. Light can not escape. 

Output: Mass ,Fuel ,Gravity
