Hey guys, Is there a theory in Quantum or general physics which states that at t0 we don't know whats gona happen at t1. But after it happens that was going to happen no matter what . Like if an atom is at X at t0. We don't know whether it would be at Y or Z at t1. It goes to Y at t1. Now no matter what we could have done or what the initial conditions were at t0 the atom would have been at Y at t1? Even if it wasn't at X at t0.
