I wouldn't say it is frozen. Or rather it is, but not for the 'mind', 'observer', or what have you.
And yeah, that is why I said there is no scientific basis behind them, because scientific method is about testing stuff and refining models.

I remember talking with some guys after a Nurse with Wound concert about difference between random and chaotic (or somesuch), thing is if something is random there are quite good models for describing it, and you can make good predicitons for random stuff.
