Buckminster Fuller said that 99% of what is real can't be seen or touched. This chart http://www.suterry.com/publicfiles/Wavelength_and_Frequency.jpg shows how small the field of visible light is. Surrounding this field are all sorts of invisible energy fields: gamma rays, x rays, infrared and ultraviolet light, microwaves, audio waves and so forth. So it's just like they said in the sixties: "Everything's vibrating, man!" Notice how the length of the wave aspect of all these energies increases as it moves toward the right of the chart. And notice how the FREQUENCY increases as it moves toward the LEFT of the chart. Interesting...
