Be warned, however, that at 977 kilograms per cubic meter, or 8.27 -- 10^50 kilograms per cubic light year, the Schwarzchild Radius of a cubic light year of cheese would be 1.23 -- 10^24 meters, significantly greater than the 9.46 x 10^15 meters in a light year. From this we can conclude that a cubic light year of cheese, should that somehow manifest itself, will immediately collapse into a black hole.
So while you would think a cubic light year of cheese would be the obvious choice over the sun, if you are presented with a choice between them, the numbers suggest you would be far better off choosing the sun.
Doing the math we can conclude it will take 1.7 x 10^17 years for our sun to generate the same amount of energy as a cubic light year of cheese.
