Is there really such a thing as randomness ? If one were able to turn the clock back, would the randomness of the decay of a nucleus really be enough to introduce a degree of difference in the macrocosmic outcome of an event?
Certainly, absolutely YES ! Can be proofed by chaos-theory.
The behavior of a nonlinear dynamical system like this exhibits a chaos-phenomenon, which is characterized by a sensitivity to initial conditions. As a result of this sensitivity, the behavior of systems that exhibit chaos is random - even then, if the nonlinear dynamical system is deterministic in the sense that it is well defined and contains no random parameters!
I have described the "essence" or "nature" of this "sensitivity" in another, prior thread. Physics and philosophers have to learn and to grasp, that matter (elementary structure) is "sensible" on very low level.. For instance, It is able to sense time and space.
