In nature nothing creates itself and nothing destroys itself.
That things are changed, and that nothing really perishes, and that the sum of matter remains exactly the same, is sufficiently certain.
Nothing is created or destroyed in nature.
A hydrogen atom in a cell at the end of my nose was once part of an elephant's trunk. A carbon atom in my cardiac muscle was once in the tail of a dinosaur.
I know that nothing is destructible; things merely change forms.
Something cannot be made out of nothing. Nor can something be made to go back to nothing.
If matter cannot be destroyed, cannot be annihilated, it could not have been created. The indestructible must be uncreatable.
Moreover, nature's blocks had to be eternal-because nothing can come from nothing.
There is nothing more certain in nature than that it is impossible for any body to be utterly annihilated.
When the film stock disappears, the matter - because movies are matter - (disappears). The laws of this have been established by Newton, Einstein, and others: there is a correspondence between light and matter, and light is matter. And energy.
There is a conservation of matter and of energy, there may be a conservation of life; or if not of life, of something which transcends life.
