The surprising fact that science works at all is a strong indication that our universe is mechanical.

What does “mechanical” mean? Isn’t it defined in terms of “laws of the universe”?

According to my current best understanding it means that it can be implemented on a Turing machine.

Interesting point of view! Never have thought of it like that. Does this entail the universe is deterministic?

You can create true randomness by including an incompressible bitstring into a deterministic computation. However, the unpredictability of local phenomena in our universe probably can be easier explained by non-locality.

Does this not qualify as hypercomputation, ie. not strictly a Turing machine?

No, why? Nothing stops you from writing an arbitrarily long sequence of unpredictable bits into the initial state of the machine.

Ah so then something exists _outside_ the Turing machine, which gave rise to it.

Exactly, this is a problem that cannot be solved from within the machine, because its inhabitants are causally insulated from it. It is a much smaller problem than any competing ontology that I know of, because a Turing machine is so very cheap to make, but it is abhorrent.
