EP,
Everything is in a state of flux. Everything vibrates. Even your single dumb brain cell.
Take color for example...

Colour is simply light of different wavelengths and frequencies and light is just one form of energy that we can actually see that is made up from photons.We are all surrounded by electromagnetic waves of energy of which colour is just a small part. Within the Universe, positive and negative charges (waves of energy), are constantly vibrating and producing electromagnetic waves traveling at an incredibly high speed.(186,000 miles per second, the speed of light.)
