T HOOFT: I do not believe that we have to live with the many-worlds
interpretation. Indeed, it would be a stupendous number of parallel
worlds, which are only there because physicists couldn’t decide which
of them is real.
In practice, quantum mechanics merely gives predictions with
probabilities attached. This should be considered as a normal and
quite acceptable feature of predictions made by science: different
possible outcomes with different probabilities. In the world that is
familiar to us, we always have such a situation when we make predictions.
That's the position of Roland Omnes'. He says QM is a probabilistic
theory, so it predicts probabilities. What did we expect?
Thus the question remains: What is the reality described by quantum
theories? I claim that we can attribute the fact that our predictions
come with probability distributions to the fact that not all relevant
data for the predictions are known to us, in particular important
features of the initial state.
The trouble with that is it's a hidden variable theory, so it has to be
non-local. That leads to t'Hooft's super-determinism.
