indeterminable
Beyond all determination
Unable to be determined, established, or decided with certainty.
An indeterminable outcome remains unknowable; an indeterminable boundary cannot be fixed precisely.
The word often describes situations where available evidence or methods simply cannot yield a definite answer: The cause of the fire was indeterminable, an indeterminable number of casualties.
Distinguished from indeterminate, which describes what hasn't been determined rather than what cannot be.
