On truth, by Johannes Koelman

This post is also available in: Spanish

In one of your articles you defend the possibility of a theory of everything. Does that imply the possibility of truth? I. e. of knowing something for a fact about the Universe?
Hawking and many others have claimed that Gödel’s undecidability theorems prevent a theory of everything. That is a wrong conclusion. Gödel does not prevent us to construct a theory of everything, but he does prevent us to turn this theory into a crystal ball. If we have a theory of everything, we will still not be able to predict the outcome of a coin flip, let alone predict tomorrow in all its details. So a theory of everything is possible, but it is a misnomer.
Now what does such a theory imply in terms of truth? Truth in this context is nothing more than the recognition of a consistent description that correctly describes measurement outcomes. So yes, I guess we will know truth – in an operational way – when we have a theory of everything.
