QR3.2.3 What Mediates Light?

All waves vibrate a medium, so light as a wave needs a medium. Something must move to make light waves but with no physical ether, current physics simply declares that:

… we accept as nonexistent the medium that moves when waves of quantum mechanics propagate.” (Laughlin, 2005, p56).

In current electromagnetic field theory, electric changes cause magnetic changes that cause electric changes and so on, in a circular fashion. So light is said to be a:

… self-renewing field disturbance.” (Wilczek, 2008, p212).

This begs the question of what renews the fields that renew? That an electric field powers a magnetic field that powers the electric field is like Peter paying Paul’s bill and Paul paying Peter’s bill. With such logic, I could borrow a million dollars today and never pay it back. According to current physics, light is a cosmic Ponzi scheme!

Figure 3.10. Physical waves vibrate matter up and down on a surface

Physical waves work by moving matter up and down (Figure 3.10). They inevitably involve friction and so by the second law of thermodynamics eventually diminish, with no exceptions. Yet ancient light that has traveled the universe for billions of years to reach us still arrives at the speed of light with its amplitude undiminished. Light as a frictionless wave of nothing is physically impossible so it can’t be based on any physical movement. A century of physics still hasn’t answered the question:

How can vibrating nothing (space) create something (light)?

In quantum realism, empty space is no more empty than an “idle” computer is idle. So the:

“… vacuum state is actually full of energy…(Davies & Brown, 1999, p140).

The source of this activity is a network that never stops. Physical waves fade by friction but light is maintained by a quantum network that is always “on”. This is the real power source behind our virtual reality. Electricity and magnetism correlate not because they mutually cause each other but because both reflect an ongoing quantum activity. Physical realism has never explained what powers light but in quantum realism, what mediates light as a wave is the quantum network.

Quantum theory describes a quantum field that Feynman called the vector potential, Born called the probability amplitude and Hiley called the quantum potential (Davies & Brown, 1999) p138. Physics today calls it the quantum function () but cannot explain why a mythical field predicts physical reality. Quantum realism agrees that there is a quantum field behind everything but adds that it is real. Quantum realism calls it the quantum field and argues that it predicts physical events because it generates them.
