OOps sorry I sent an empty post by accident. I agree with you here. But I am new to this field so I am uncertain about so many things. However, I don't understand why it is that a UD would know how to generate these law like sequences of states. It may well generate all possible programs that generate all possible universes (with different values for the physical constants say - maybe even different laws) but I wonder why our conciousness defines itself by "selecting" only those "consistent" extension among all the states available that obey a certain set of laws of physics.
I thought that a TOE should explain the laws of physics and Bruno states in his SANE paper " Conclusion: Physics is given by a measure on the consistent computational histories, or maximal consistent extensions as seen from some first person point of view. Laws of physics, in particular, should be inferable from the true verifiable ‘‘atomic sentences’’. Those are the verifiable arithmetical sentences. They should be true everywhere (= in all comp histories), true somewhere (= true in at least one comp history), and inferred from the DU-accessible ‘‘atomic’’ states". It feels a bit lie a chicken and egg situation - do we pick out the laws or do they pick us?. But I am still working my way through this and and loads of other stuff, so I don't understand it yet.
