On the issue of proving '2 to the power of N', the two presented many mathematical proofs and coincidences that arose during the process.
Of course, that cannot serve as a perfect chain of evidence, but that's how theoretical physics is. The reason for having theories is that they are temporarily unverifiable research, aimed at explaining some unexplainable problems.
Now that their research has produced many astonishing mathematical coincidences, it is enough to support the inference of the relationship between '2 to the power of N' and mass.
Zhao Yi and Edward Witten worked tirelessly for several days, finally completing their research and proofs.
Both of them felt exhausted.
On the day they finished, Zhao Yi slept for a long time, did not want to think about math problems when he woke up, and simply returned to the student dormitory. He played games with Fan Lei and Li Renzhe and played soccer on the field in the afternoon, enjoying college life again.
