>This first idea that math have some intrinsic limitations - eg: you can’t compute all the Busy Beaver Numbers

But this is not a limitation of mathematics at least not any more so than there being no largest prime number is a limitation of mathematics. It is a limitation on abstract systems, such as Turing machines.

The halting problem is not that you can not deduce whether any given Turing machine halts, but that there is no Turing machine that deducing this.

Gödel's (ö and o are different letters, by the way) theorems are far more wide reaching, as they appy to large classes of axiomatic systems, but they are only making claims about the systems in relation to themselves.
