Prologue
Parallel worlds - a very nonsense thing, but there are all kinds of strange worlds, if there is a world that is very similar to us, there are you and me, from the perspective of probability, close to zero. Pen | fun | pavilion www. biquge。 info
People like to think about problems with probability, but they don't think that probability is given by people, does probability really exist, maybe our world has already been arranged, we are just developing according to a fixed route. We use probability to explain the existence of a person, it is almost impossible, there are too many coincidences, not to mention that in millions of years of evolution, after countless natural disasters, wars, accidents, the probability of your ancestors to survive, just to say that the probability of you standing out in the hundreds of millions of mirrors is already one in billions. Coupled with the butterfly effect, perhaps one butterfly in ancient times could be a movement of billions of other people standing on this land thousands of years later. If your ancestors married someone else at the slightest thought, it may affect the marriage of the vast majority of people at that time. Your existence is so fragile that you may not exist if they decide to have a child one day, ejaculate early or ejaculate a second late. Don't dream of traveling, let alone dream of changing major events in history, because when you step on a flower in that era, you will cease to exist. Speaking of which, do you think it's great to be able to exist in this world, but if you explain it in a parallel universe, there must be something possible.
13.3 billion years ago, the Big Bang produced countless bubble-shaped small universes, these small universes continued to expand, each small universe gave rise to countless galaxies, each galaxy gave rise to countless solar systems, one or more planets exactly the same as the Earth, and even creatures or humans are the same as the Earth, the possibility of such a "mirror" planet is almost zero, but as long as possible, there must exist, and there may be countless more, we call them parallel worlds.
The following narrative really exists in parallel worlds:
