    Actually that's doubtful.  You're idealizing "object" into a
    class.  A specific duck or atom may require and infinite string to
    define it's relation to the rest of the universe.  But you've
    tried to pull a switch from "being" to "represented"; a common
    move for those enamored of language, description, computers,...


I meant a structure-preserving, complexity-preserving representation, at least in principle. So the binary string would completely represent the structure of the real object. But there may be a problem with calculating probability if there is an infinite number of objects. For example, it may seem that there are more natural numbers than even numbers but actually they are both infinite numbers. I don't know how Solomonoff got around the problem with infinity.

    A supposition on the same order as nature has regularities. 
    Remember you're talking about "properties" within theories...not
    necessarily the same as within objects.


I am talking about properties of objects - atoms, ducks, worlds..

But the regularities of nature are in the theories.  The explain how a duck flies, but they don't explain why /*this */duck flies while /*that */one swims.  Physics leaves to particularities to historians.
