> it's definitely not impossible a priori and especially not because of Gödel. You forgot something there: you know the underlying system and about its existence. In the absence of this knowledge it's indeed impossible to know. Here's an example from real-life physics: there's no way of telling by means of measurement, whether you're accelerating or at rest but subjected to a gravitational field. A software example would be this: how would a program written and running in Factorio (like Pong [0]) be able to tell that it's implemented by means of video game mechanics running in an emulator executed within a VM on server hardware? If the programming environment itself features no way of interrogating its runtime environment, then there's just no way.
