Because in such a distant past, as long as one step is wrong, the present will be changed drastically. Imagine if you are thirsty, just dig a hole to find spring water. After the spring water gushes out, it flows endlessly, accumulates into ponds, merges into lakes, and forms an inland sea…As a result, today, perhaps the outline of a continent has been changed, and human history Also beyond recognition. This is the “butterfly effect”: as time goes by, even a small change in the chain reaction is enough to turn the world upside down.
A countermeasure: Fixed errors

When the other self appears, it is like a “program error”: there is a kind of echo between the two, and it will be repeated continuously, eventually leading to an explosion! Fortunately, just like the “Larsen effect” on an electric guitar, as long as the two are moved away from each other, this deadly echo disappears without a trace.

In fact, Martin’s story vividly illustrates the “Novikov principle of self-consistency”: Soviet scientist Igor Novikov proposed in the 1980s that if an event can completely change the course of history, it will be fundamental Impossible to happen, but will be automatically corrected by a series of other events. It seems that although there are occasional “small disturbances”, nature can still figure out a way to get the time train back on track.
