i don't know if they can do that at nhis, but it struck me as a good indication. when you have this kind of resonance and you stop it and start it, you're interfering with normal healthy cells, the conditions of life out of which we evolved. we came from a microwave world, and i'll leave you with one other passage that i thought really struck me as amazing. how much microwave radiation we had at the beginning of the world so to speak. microwave radiation was around in the big bang. we know that because the scientists who received the nobel prize in 1978 got it for discovering the cosmic microcafes in other signals that supported the big bang that occurred 15 billion meres ago. this explosion of radiation, matter, and energy, gave rise to all nature and civilization that we have today. it is sobering to think the microwaves in the world now that spilled from that explosion are billions of times less frequent than those emitted by the planets cell phones and other devices today. i think it's something to think about. thank you. >> debra davis is a visiting lecture a
