Hi all,
Stephen Hawking extended the Godel's Theorem to physics and hence expressed that single TOE does not exist. So, does that mean that single GUT cannot exist as well? I guess not, in a sense that GUT might not necessarily mean TOE. I just want opinions. Sincerely DPA

strange;
I would say that a ToE can exist, but that we are not able to construct a proof

Obviously, the goal of physics is not to find every mathematical statement that's true. So Godel's incompleteness theorem does not apply.

Namely, he does not EXTEND the Godel's theorem, but merely uses it as an analogy illustrating the (certainly not new) idea that the final physical theory of everything might not exist.

my word was misleading.

What does a theory of everything even mean?
I recall reading that Lord Kelvin said at the start of the 1900's that the field of physics is done, i.e nearly completed to describe every natural phenomena. He didn't account for the two revolutions that followed, QM and GR.
