But I think this theory:

is even better.
....There is no wavefunction, no special role for observation and no fundamental distinction between macroscopic and microscopic....

....our approach can reproduce all the standard features of quantum mechanics, including twin-slit interference, zero-point energy, barrier tunnelling, unpredictability and the Bell correlations mentioned above.....
