Existence-life-is an illusion caused by a literal friction between time and space. The continum of time space is in fact not frictionless, and it is the grinding that we mistake for life.
The process of movement in an everyday scenario is one where our physical form are pressing through an »empty space« that is actually other atoms which are of the same basic matter. As those »seperate« forms move past each other they each get »used«, older, from having experienced whatever exchange between particals went on in the brief instant that they interacted. This is the process of aging and deterioration in all things material. This is Life.
