More MYSTERIES of the Creator.....
And God said, Let there be light: and there was light. Genesis 1:3
"Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. 
Experiments led by Hrvoje Petek, an R.K. Mellon professor in the Department of Physics and Astronomy examined ideas surrounding the origins of light, taking snapshots of light, stopping light and using it to change properties of matter.
The team performed an ultrafast microscopy experiment, where they trapped green light pulses of 20 fs (2×10-14 s) duration as composite light-electron density fluctuation waves, known as surface plasmon polaritons, and imaged their propagation on a silver surface at the speed of light. But they did this with a twist so that the light waves came together from two sides to form a light vortex where light waves appear to circulate about a stationary common core as a whirlwind of waves. They could generate a movie of how light waves churn on their nanometer (10-9 m) wavelength scale by imaging electrons that two light photons coming together cause to emit from the surface.
.............by sending in two light pulses with their time separation advanced in 10-16 s steps, they could image how light waves come together causing their joint amplitude to rise and fall at fixed points in space forming a light vortex on the nano (10-9 m)-femto (10-15 s) scale.
Such light vortices form when you shine your red or green laser pointer onto a rough surface and see a speckle reflection, but they also have a cosmological significance. The light vortex fields can potentially cause transitions in the quantum mechanical phase order in solid state materials, such that the transformed material structure and its mirror image cannot be superimposed. In other words, the sense of the vortex rotation generates two materials that are topologically distinct.
Even the forces of nature including light, are thought to have emerged as symmetry breaking transitions of a primordial field. Thus, the ability to record the optical fields and plasmonic vortices in the experiment opens the way to perform ultrafast microscopy studies of related light-initiated phase transitions in condensed matter materials at the laboratory scale."
