KEY POINTS: One of the most important laws in all of physics is the conservation of energy: that energy can change forms, but can never be created nor destroyed. At a fundamental level, however, that's only true because there's an underlying symmetry that the Universe obeys: time-translation symmetry, that it's the same from one moment to the next. Only, that's not true in the expanding Universe: the Universe is different from one moment to the next. As a result, energy is not conserved, with truly cosmic implications... (MORE - details)

Quote:As the Universe increases in volume, the total amount of “dark energy” increases as the volume increases: a Universe that’s eight times the volume has eight times the amount of energy in it, and as it continues to expand, the energy within the Universe increases without bound as well.

Perhaps as the universe expands man will learn how to use this increasing energy for his advantage. A never ending source of energy. Seems to be a promising area of research.
