There is no such thing as a fixed or stationary thing. Everything is in constant movement. Not in millionths of a second, but in millionths of a millionth of a millionth. Subatomic particles are created out of the void, out of space, and again enter into space. It is the same thing in a small time period that happens in a great time period when God or Brahman or the Universe expresses itself and begets planets and plants and animals and people and spiritual longings, and then contracts again and turns it into nothing in billions of years.
