The trillions upon trillions of years that an ordinary sun will continue to give out heat and light well illustrates the vast store of energy which each unit of matter contains. The actual energy stored in these invisible particles of physical matter is well-nigh unimaginable. And this energy becomes almost wholly available as light when subjected to the tremendous heat pressure and the associated energy activities which prevail in the interior of the blazing suns. Still other conditions enable these suns to transform and send forth much of the energy of space which comes their way in the established space circuits. Many phases of physical energy and all forms of matter are attracted to, and subsequently distributed by, the solar dynamos. In this way the suns serve as local accelerators of energy circulation, acting as automatic power-control stations.
