| In a classical Newtonian universe, a snapshot of the position and momentum of every particle at one moment would allow you to extrapolate exactly what would happen at any point in the future or had happened at any point in the past.
Problem is, it doesn't work because the Newtonian universe is wrong. Heisenberg uncertainty principle dictates you can never know the position and momentum to an arbitrary degree of accuracy, and quantum mechanics means you can only work out the probability of events happening.
Therefore, the scenario described can't ever happen. |
