Actually I was told this in a Youtube comment discussion.
I kind of get it that "math is self consistent". For example 2 + 2 should always give 4 under ALL circumstances. So, even in a parallel universe in the multiverse 2 + 2 will still be 4. So that is consistency from the point of view of a layman, right?
But does Godel's theorems have implications in physics where we search for "knowledge"???
I.e. Does these 2 theorems put a limit to knowledge we can obtain about the universe through physics???
