What can we say about nature?
Luigi Foschini

TL;DR
This essay explores the role of language in understanding reality, emphasizing that choosing the appropriate language is crucial, especially in frontier sciences like quantum gravity where empirical data is lacking.
Contribution
It highlights the importance of language and semantics in scientific theories, particularly in areas lacking experimental verification.
Findings
Language shapes our understanding of reality
No definitive theory in quantum gravity yet
Emphasizes questions over concrete solutions
Abstract
In this essay, I review the importance of languages in the study of reality, following the well-known aphorisms by Galilei, Bohr and many others. The emphasis on these aspects helps us to understand that it is not meaningful to ask if the reality if "digital" or "analog", but we have to search what is the best language to study some specific aspects of the reality. This problem is particularly felt in the case of frontier science, like quantum gravity, where, in front of several theories (syntaxes) available, there are presently neither observations nor experiments leading to the building of a convincing semantics. You will not find here recipes for a definitive theory. Just thoughts and questions.
