The principal features of quantum theory contradict "cause and effect" relationships (relativity) by assuming that random, spontaneous events can and do occur within a quantified limit (specified by the Heisenberg Uncertainty Principle). Therefore, a future event (or non-event) has both a multiple probability (statistical) and a quantum probability of 50/50 that is not predictable.
As the observer is outside the event horizon, there exists two realities; that is , a state of existing (or being) and that of not existing.
Just as it may be that one dies, one does not "know" when one dies; the quantum state would be both dead and alive while the relative state would be dead or alive.
An again, reality is based on the perceptive analysis of the observer; at any given time the observer is outside the event horizon and is in the present or the past.
However, there is an relativistic assumption that there exists a continuum for all sets, but this cannot be made from a quantum state.
Quantum reality transmutates the objective into the subjective, and the phyical into the metaphysical.
