I could say specifically what it is from, but this diagram works
  for so many things! For me, for example, it helps with the
  question "why Are there objects in the Universe and spaces
  inbetween them?" Why isn't everything exactly like everything
  else? Since the fields/wave lines in this diagram Analogize to
  magnetism electricity hydrolics gravity light wind Electrostatic
  charge, etc Despite what it was originally intended to
  represent, it can represent quite a lot of everything. "
