- The quantum vacuum is the arena where fundamental physical processes take place, and is by no means a simple empty space where nothing ever happens or a pure abstract concept of quantum field theory. Many of these fundamental processes are nowadays well understood.
[atheist] Hartmut Figger and [atheist] Dieter Meschede, Laser Physics at the Limits (New York, NY: Springer Publishing, 2002), 197.
- Even if the matter fields involved in the vacuum state are rather peculiar and certainly not observable in the sense that ‘real’ particles are, it is a mistake to think of any physical vacuum as some absolutely empty ‘void’.
[atheist] Christopher Ray, Time, Space and Philosophy (New York: Routledge, 1991), 205.
