Ruth & Rindler (General)

Dhw There is, as far as I can judge, no difference between Ruth's transactional interpretation of quanta as a process of emission and absorption, and the everyday process of perception, whereby an object emits, the senses absorb, and the brain interprets.
 
DAVID: There is a major difference. First of all, Ruth is saying that the Heisenberg 'layer' of reality (HLR)is not our reality. Our spacetime is intimately connected to this other layer, but separate from it. The HLR is quantum energy in many possible potentialities, all interconnected. This is why spookiness at a distance works faster than the speed of light. In the HLR there is no need for speed of light.-My reference to everyday perception is an analogy which you've taken out of context, because I go on to relate it to Ruth's claim in her Rindler section that her theory makes "the problem evaporate" ... i.e. that of the subjectivism of interpretation and the possibility that quanta do not exist. I can't follow the reasoning behind her claim. All the same, the discussion you're having with BBella may be more fruitful than my questions for Ruth in illuminating the relationship between QM reality and that of our own world.
 
I hadn't realized that the Strassler piece on virtual particles which are not particles was the same as the one you referred us to earlier. I quoted it myself on 30 July at 12.21! But perhaps the article on magnetoreception (under Nature's Wonders: Migration) is even more enlightening, if only as another analogyAVID: More on magnetoreception, a sense we humans don't have but migratory animals do. Iron compounds and quantum reactions are all present:-http://www.the-scientist.com/?articles.view/articleNo/36722/title/A-Sense-of-Mystery/-QUOTE: Indeed, the question of how animals can detect magnetic fields has proven maddeningly difficult to answer, and scientists are only just beginning to elucidate the physiological mechanisms behind this mysterious extra sense.
"This is a sense that doesn't exist in humans, so we don't have any intuitive feeling for what it would be like to perceive magnetic fields," says Ken Lohmann, a neurobiologist at the University of North Carolina at Chapel Hill, who studies the navigational abilities of sea turtles and other marine animals. "In addition, unlike most other stimuli, magnetic fields go right through biological tissue, so in principle the receptors could be anywhere in the body, and they may not be clustered in one place."-BBella asks in what way QM reality is separate from ours. Maybe the answer is that it's not. Maybe we simply have no way of reaching beyond our subjective perceptions, and so at least for now we have no way of grasping all the realities around us. But animal perceptions show clearly that there are realities beyond those we ourselves can perceive, and perhaps (very tentative!) these may also be emissions absorbed by a "mysterious extra sense" in some humans that underlies what we call psychic experiences. Is that what you're getting at, BBella?
