source however distant, we know that there must be a continuous body of ether between us and it. Now astronomy shows us that we receive light from heavenly bodies so distant that, though it travels with the incredible speed of 186,000 miles per second, it takes more than two thousand years to reach us from some of them; and as such stars are in all quarters of the heavens we can only come to the conclusion that the primary substance or ether must be universally present.

This means that the raw material for the formation of solar systems is universally distributed throughout space; yet though we find that millions of suns stud the heavens, we also find vast interstellar spaces which show no sign of cosmic activity. Then something has been at work to start cosmic activity in certain areas while passing over others in which the raw material is equally available. What is this something? At first we might be inclined to attribute the development of cosmic energy to the etheric particles themselves, but a little consideration will show us that this is mathematically impossible in a medium which is equally distributed throughout space, for all its particles are in equilibrium and so no one
