The standard definition of scalar waves is that they are created by a pair of identical waves (usually called the wave and its antiwave) that are in phase spatially (space), but out of phase temporally (time). That is to say, the two waves are physically identical, but 180 degree out of phase in terms of time. They even look different – like an infinitely projected mobius pattern on axis.
The DNA antenna in our cells energy production centers (Mitochondria) assumes the shape of what is called a super-coil. Supercoil DNA look like a series of mobius coils. These mobius supercoil DNA are ( science will not verify this, so for now it is hypothetical) able to generate scalar waves. Most cells in the body contain thousands of these mobius supercoils, which are generating scalar waves throughout the cell and throughout the body. Scalar energy can regenerate and repair itself indefinitely. This also has important implications for the body DNA synthesis.
A scalar wave is also called a Standing Wave, it is a pattern of moving energy that stays in one place. Waves we generally think of as moving through space as well as vibrating "up and down" but a scalar wave is stationary, or standing. Scalar waves are used by the controllers to generate interference or feedback systems or to stimulate the nervous system of bodies to repeatedly loop in a certain manner - well if you can visualise the kind of waveform described you can probably imagine.
