Degraded Wormhole

On December 15, 2015, CERN held a press conference and announced to the world that it had observed a new two-photon signal: 750GEV. That day, the venue was full, with many people sitting on the floor. In August of the following year, 750GEV was speculated to be a "graviton". Until May 19, 2017, an SNS user hyperio released news, using precise calculations and rigorous experiments to confirm that the 750GEV two-photon signal was indeed a "graviton", which caused a sensation in the academic world. Related publications were quickly published. The particle was officially named digamma, and the world line was divided into two.
