The number of NDEs grows as medical technology advances and is being taken seriously by an increasing number of neurologists and doctors. That consciousness of some kind is able to exist indepedently of the body is now almost certain. Cases have been recorded where the patient knows what is going on around him, in detail, despite being brain dead, having his eyes covered and his ears plugged.
It is only because I have had time in the last few years to look into the deeper implications of the diverse divisions of science, albeit subject to my limitations, that I've become aware of the strangeness of our existence that seems to have escaped the awareness of many competent but highly specialised scientists cocooned in a fragment of the total picture. Listed below are some aspects of reality which are now accepted by people in the various disciplines, though few of them seem to have grasped the whole.
Nothing is solid but much appears solid. A lump of lead is totally space and energy put together to give the impression of solidity.
Time, space and matter are interconnected by Einstein's equations.
All entities are instantanously connected in some way, independently of their separation in time and space. Thus quantum events in our neurons, in fact in all the cells of our body-brain system, are instantanously connected to all quantum events in the universe - past, present and future - including the point of the Big Bang creation. This arises from quantum entanglement.
Quantum events, including those in our own brains, affect what we call past events as well as future ones. (E.g. the delayed choice experiment in quantum physics).
Physical reality is of such a nature that it cannot be fully described by mathematics or physical models on a one-one basis; i.e. science will never be able to describe more than limited aspects of reality. To attempt to do so would be like squaring the circle.
