No worries. No one can. Everything we can observe is perfectly explained either by relativity or quantum physics, but never both. They are incompatible theories, which are applied in different conditions. In such extreme conditions, both would apply. IE, we don't have a theory for it.

Since we cannot create anything remotely close to such conditions, like a black hole, we do not have the data to create such a theory. Just like AI, we are limited by our training data.
