"We have demonstrated that it is impossible to describe all aspects of physical reality using a computational theory of quantum gravity," says Dr. Faizal. "Therefore, no physically complete and consistent theory of everything can be derived from computation alone. Rather, it requires a non-algorithmic understanding, which is more fundamental than the computational laws of quantum gravity and therefore more fundamental than spacetime itself."

Seems like quantum gravity theory might be missing something, no?

It's such a silly idea that whatever is simulating us would be in any way similar or care about what's possible in our universe. It's like a game of life glider thinking it can't be simulated because someone would have to know what's beyond the neighbouring cells and that's impossible! But the host universe just keeps chugging along unimpressed by our proofs.
