What are Scalar Fields?
Scalar fields can be thought of as similar to a rope, tied at one end. Forward and time-reversed waves become locked in resonance with one another, creating an energy field. Two particles become connected, represented by your hand and the hook.
The scalar field goes in all directions, but a receiver will absorb this energy, in a similar way to the ionised gas in a plasma ball. The finger absorbs the energy, and a stream of electrons passes through the glass to the finger. When this happens, the energy becomes more focused.
