You have been stuck on these matters since the early days of Vic's discussion forum. In spite of mine and other's efforts you keep "not getting it." I can't write a treatise here. It would be a waste of time. If you want to read a book on this look at Redhead's book on the metaphysics of QM. I can't advise any further, but you will have to study this in greater depth and be willing to cast intuitive and metaphysical baggage aside. LC > > > >> If you refuse to accept them then fine.
