comment Is it possible for a physical object to have a irrational length?
@Jerry Well, yeah, it is possible to have an object with rational length. You only need to adjust the infinitely accurate scale so that a given length becomes exactly rational. However, if you keep a fixed scale such that one length becomes rational, it should always be possible (to the point where it's trivial) to find a length that is irrational.

comment Is it possible for a physical object to have a irrational length?
I think, comming up with a scale like that isn't what the question asks for: Take the right Isosceles triangle in the example. It assumes that you meassure the side-lengths with length 1 and thus, the hypothenuse has to be $/sqrt{2}$. The question essentially is: Given you use an infinitely accurate scale in which one of the sides comes out rational, would, on a physical level, all sides be rational (two of them of miniscully different length) or could two of them possibly be exactly the same, making the third side irrational? (or the third side could be rational and the other two irrational.)

comment Hamilton operator in absence of causal order?
I'm not entirely sure. At the very least they mention general relativity in their paper in two contexts: Assuming only local correctness of QM is equivalent to assume only local flatness of space in GR. And in the sublementary informations to the paper (see the very bottom of the linked page for a pdf of that), they mention that one term of the generic solution to a two-observer-problem, which, however, breaks unity of probability, is equivalent to a certain kind of time-like loops as described in one of their references. So if GR gets a mention, SR surely is related as well.
