# A coherence law for retro-causation: the observer.

The observer from the future...

The idea of a "fixed block universe", such that all past,
present, and future is already fixed and given (and that
all thought of free will or chance is illusory) is neither
satisfactory nor warranted: and not even quite reasonable.

The idea of a "growing block universe" is a bit better,
but, either the past does not exist either, i.e. only the
*proper* present exists, or the future does exist, too
(that difference being mostly a matter of "conventions").

The idea of a "dynamic block universe" is most natural:
*we are pure induction in action*, which is beyond and
before *physics*...

Meanwhile:
- symmetry <=> conservation
- coherence <=> (cancellation down to least) action

And that should be my last post on the matter for a
while, though I remain open to questions/questioning.

Cheers,
