The last topics are dark matter and dark energy.
Although never observed, even quantum theory fails to explain why the mass of the observable universe is far from sufficient. Thus, how to accurately connect quantum entanglement with the quantum geometric structure of space-time, and describe their dynamic interactions, remains an urgent but difficult challenge at present.
The most most most important aspect was that past research at least had the papers of predecessors for reference.
But when utilizing the toolkit he developed to study these problems, there was almost no meaningful reference at all, relying solely on brainpower to slowly consider the complex structures of space-time and to devise corresponding mathematical structures.
It was this that had even Qiao Ze, who recently felt exhausted and had to pause this line of research, take a break by solving Goldbach's conjecture to rest his mind.
