Wave nature of light


What is space?

Ultimately, at small-enough dimensions, physical effects lose the continuity that our crude senses give them. Movie frames flashed before our eyes at twenty-four frames per second seem continuous, yet the quantum nature of film is well established.

The mind cannot comprehend a substance that has simultaneous natures of both particle and wave. It is not like mixing black and white, or reducing the squares of a vast checkerboard until we cannot distinguish the pixels but see only a field of gray.

Werner Heisenberg taught that the probabilty of being in one state or the other was not resolved until we measure it. Until it hits the eye, light has a virtual existence as both particle and wave. Could the same be true of space? If virtual particles inevitably exist in the absence of particles, maybe it is the dark energy that can explain the expansion of the universe.
