                        Plato's heaven, or any random Turing machine
                        will support intelligent life?
                        1 in 10, 1 in 1000, 1 in a billion?

            Zero.

        Does that allow us to argue:

        1) A universe selected from an uncountably infinite number of
        possibilities has measure
        0
        2) Our universe exists so it has measure>0
        3) Our universe is not selected from uncountably infinite
        possibilities
        4) MUH indicates any universe must be selected from uncountable
        infinite possibilities (since all
        of maths includes the real line, etc)
        5) MUH is false.


    Hmmm.  I think we argue that objects in Plato's heaven and Turing
    machines are not the right kind of things to support life.



I am very puzzled by this statement. You could help me understand by answering the following questions:

Why couldn't there be an accurate simulation of life on a Turing machine?

Because a Turing machine is an abstraction. If you mean a realization of a Turing machine, then I suppose there could be a simulation of life on it.


How can entities within a universe that exists in Plato's heaven distinguish it from a universe that does not?

I doubt that Plato's heaven exists.  So no universes would exist in it.
