Your welcome.
and I must say that I "do" understand what you are implying, all the more reason to be in agreement with you.
Meanwhile, I would also like to make another suggestion here...
What's at the base of a cathode ray tube in the back of your TV?
a doughnut shaped electromagnet.
what's in the back of your radio?
again, an electromagnet
and what's in back of the human brain?
a bio-electric form of an electromagnet.
Even the earth itself contains a huge electromagnet, including the micro-universe of spinning electrons, protons, and other various forms of spinning entities all contain their own capacitance of electromagnetisim of sorts.
remember, all things (animate & inanimate) radiate a residual "electromagnetic signature" even the smallest can be detected and traced to it's point of origin anwhere, and any "Time"
When you think in terms of radio waves, and how the brain functions like a radio, the base of which all have a link to some form of electromagnet be it to send, or receive, IMHO a Television picture tube, a radio, or even the brain itself all have an electromagnet in which the carrier waves all pass through an electromagnet before transmitting a signal, the same in reverse is used to catch them.
This electromagnetic signature is also very much like a DNA fingerprint, which would explain why people are able to see ghosts & apparitions of our dearly departed, including the recent research of EVP which picks up the voices of the dead so to speak, they are not really living ghosts per say, but in fact a "Recording" of that electromagnetic signature of the persons essence. Albeit they have left the building, their ELM signature can be detected and yes you can even communicate with it very much like communicating with your computer, but it is a memorex copy of the intelligence of the former persons program that is still running in the background radiation.
My point is... It may be very possible that these ELM signatures could be used to navigate selected places in Time reversal as well.
