This was a perplexing yet fascinating hypothesis: suppose there was such a thing, truly existing somewhere, yet neither you nor anyone you knew had ever learned any information related to it. You did not know what it looked like, where it came from, where it was, or even whether it existed. No one had ever told you that such a thing existed somewhere in the world. At the same time, it would have no effect on you whatsoever. Whether it was born, evolved, or vanished, there would be no intersection of information between it and you.
Then did such a thing truly exist, as far as you were concerned?
After such a thing disappeared for some reason, had that event truly happened, as far as you were concerned?
That was the situation. Many worlds should have been discovered, yet in the end, not a single person found them. From the moment they were born, you knew nothing of them, and after their destruction, they left behind no trace whatsoever. No matter what you did, you could not find proof that those worlds had once existed or had once been destroyed. You could only infer from statistical figures and experience: oh, there should have been something here, but now it was all gone—even their end could only be concluded through indirect deduction, and it was a conclusion that could never be proven or disproven by observation.
That was what happened when the Void Cataclysm occurred.
"The exact point in time will probably never be confirmed, because you cannot determine when something that only existed statistically vanished—if you determined that point in time, that thing would not have vanished after all, because you would already know it existed. And during the Void Cataclysm, not a single discovered world was destroyed," Chen Xiao
