There is a very strange phenomenon in quantum mechanics: why do all electrons look the same, they have the same mass, the same charge, and the same spin, so that we can't find any trace of them from these electrons that can distinguish them.
In fact, decades ago, in a seemingly mundane phone call, two leading physicists came up with crazy ideas for "deviance" on the subject. Back in 1940, Feynman was in his graduate dormitory at Princeton University when he received a call from his mentor, John Wheeler.
"Feynman, I know why all electrons are the same charge and the same mass."
"Why?"
"The reason is that they are all the same electron"
Wheeler believes that the reason why we see all electrons the same is because there is only one electron in the universe itself, and this electron travels back and forth in space-time and participates in all the events in the universe. It gives us an intuitive look as if the universe is full of electrons. This is Wheeler's single-electron theory of the universe.
In the microscopic quantum world, the direction of time passing is not singular. That is, electrons can travel from the past to the future, and can also go back to the past from the future. Those who like to watch Doraemon must remember that in many stories, several Nobita appear at the same time at the same time, some Nobita who returns to the present from the future, and some Nobita who finds it from the past. But these Nobitas are all the same.
If I can travel through time and space, how can I create multiple mes now: set three time points: the past time at 7 p.m. I went to the world at 8 p.m. to see what I was doing, the current time at 8 p.m. I sat in front of the computer, and at 9 o'clock in the future time I just came back to tell me something important. This results in 3 I's present at 8 o'clock. String these three points in time into a line and comb through what I did that night. At 7 o'clock, I wanted to go to the future to see what I was doing, saw me sitting in front of the computer, and went back. At 8 o'clock, I was already sitting at my computer desk. Then at 9 o'clock when I was ready to take a shower, I remembered that I forgot to turn on the water heater, so I went back to 8 o'clock to remind me to turn on the water heater at 8 o'clock. So these three I am the same person. In extreme cases, the same point in time can create countless selves and fill the world at the same time.
In addition, I at 7 o'clock and I can also fill up at 9 o'clock at other times. Like yesterday and the day after tomorrow, last year and next year.
So, when I go back and forth at the same time, I create countless illusions of me. I'm actually the only one.
The same is true of electrons, which can travel countless times, creating an illusion that fills the entire universe. The reason why all the electrons we see are the same is because they are actually the same electron. This electron travels back and forth in space-time, participating in all the events in the universe.
This is like a plot told by a brain-burning drama: a person marries himself, gives birth to himself and kills himself, not only his parents are alone, but even his grandparents are himself. Interested friends can take a look, the science fiction novel "You Returning Soul Corpses", remade into the movie "Former Destination".
Electrons also have positive and negative charges, and Wheeler guesses that if electrons are negatively charged from the past to the future, and positively charged if they return to the past from the future. The protagonist of "Former Destination" is also, who starts out as a woman and ends up returning to the past as a man.
According to the Heisenberg uncertainty principle, pairs of positive and negative particles are constantly created out of thin air in a vacuum, and they will be annihilated in a very short time. This phenomenon is known as quantum fluctuations, and the single-electron universe theory can explain the creation and annihilation of positive and antimatter. When an electron moves from the future to the past, neither positive matter nor antimatter exists before it changes direction, and at the moment it changes direction, positive and antimatter will be produced at the same time, and (for those traveling from the past to the future) in our view, this pair of positive and antimatter is created out of thin air. This phenomenon is creation.
Annihilation is the opposite. When positive matter travels from the past to the future, positive and negative matter exist together before changing direction, and after the direction of time changes, we see nothing
In quantum mechanics, particles of the same class with exactly the same intrinsic properties are called homogeneous particles, and in addition to elementary particles such as electron photons, composite particles such as neutron protons are also indistinguishable homogeneous particles. If the hypothesis of a single-electron universe is true, it means that there is only one electron, photon, proton, and neutron in the universe, which are spread in every space of the universe in an infinite cycle, and at every point in time from the birth of the universe to the end of the universe, making up everything in the universe, including you and I [cover face] [cover face] [cover face]
