I wonder if there exist some type of electromagnetic waves, which do not experience virtually any kind of interference and could freely go through the world.I know there exist some ELF communication with submarines and ELF waves could penetrate deep into the ocean.Does that mean that the lower frequency we have the farther it will go?As I know there is no lower limit to frequency of EM waves.What if we have frequency of 1/millionth of hertz?Will it penetrate the Earth core?I think we would use such comunications to avoid or reduce payment to Internet or cellphone providers.We could use pulsed sub-ELF waves which would produce billions of pulses per second and encode bits in such way.One problem here could be size of antenna.But I know that human brains produce ELF wave which could be picked with encefalographs.How brains are able to generate them?
