"How does God Play Dice?
(Speculations about Quantum Mechanics at the Planck scale)"
Attempts to arrive at consistent theories combining
Quantum Mechanics with General Relativity not only require new
concepts of space, time and matter, such as the ideas that lead
to Superstring Theory, D-brane theory and M-theory, but they
may also require a reconsideration of what Quantum Mechanics
itself really is about. Although completely deterministic
scenarios appear to be ruled out by the Bell inequalities,
it is nevertheless worth-while to investigate a set-up where
we start with a deterministic theory and add to this the
notion of information loss. Although models proposed so-far all
show deficiencies of some sort which makes them unrealistic for
describing the real world, these models do show how chaotic
phenomena in a deterministic theory might be suspected to lie
at the basis of the quantum nature of our world.
