The stars seem immutable, but they are not. They are born, evolve and die like living organisms . . .
The elements of which our bodies are formed were manufactured . . .
In the interiors of stars now deceased, and distributed to space when those stars exploded . . .
If the sun explodes, at the end of it's life, the planets will be consumed and their substance one more distributed into space, to be reincarnated in another solar system as yet unknown.
