in the previous article we talked about Thomas Yang’s famous double-slit experiment , which can be ranked among the top ten most classic experiments in the history of science.
is to place a flashlight in front of a piece of paper with a small hole in it, and then put a piece of paper behind the paper. The difference is that there are two parallel slits on the second piece of paper. The light emitted from the small hole passes through the two slits and is thrown onto the screen, forming a series of stripes that alternate between light and dark.
This experiment has become an excellent example of supporting the fluctuation theory of light. The Yang double-slit experiment is also called the interference phenomenon of light, and the term interference was also proposed by Yang for the first time. He confirmed that optical fibers pass through two small holes with parallel and small distances. Through the two small holes, light with the same frequency will affect each other and project a pattern of light and darkness
. This experiment later also provided inspiration for Einstein's light quantum theory. When you reduce the intensity of light until only one photon enters the entire experimental device each time, the strange journey begins. In 1905, Einstein had made it clear that a single photon was a particle. Therefore, Einstein's light quantum theory proposed by light explained the photoelectric effect and won the Nobel Prize for this.
And another experiment derived from this double-slit experiment - the electronic double-slit experiment experiment, can be said to have directly subverted the entire world.
Let me sort out the background with you. The double-slit experiment refers to light passing through the slit of the wooden board and shooting on the screen. When it penetrates into the microscopic field, it becomes an electron double-slit experiment. The electrons move in the form of waves. Due to interference, traces will appear after passing through the double-slit.

But even if one electron is emitted one by one, interference will occur. The stripes appear clearly on the screen. What exactly happened? .
Copenhagen explains that a single electron passes through two gaps at the same time, allowing the electron to interfere. The interference fringe appears clearly, which shows that the electron does pass through two gaps at the same time. The electron's wave-particle duality makes it pass through the gap, and then interferes with itself, showing its own particle nature on the screen, so it produces interference fringes. But Einstein expressed his objection. How could a single electron pass through two gaps? Can electrons clone the technique? The distance between the two gaps is very small (10∧-9 meters), but for electrons, this distance is 27 billion times the height of electrons.
Nuclear model atoms and electrons
But the single electron does pass through the double slits, causing interference. So how exactly does electronics do it! This problem keeps bothering everyone!
Since you are all arguing, let’s just use the camera to observe it!
But at this time something strange happened. When the experimenter added the device to induce the electrons through the passage, the interference fringe disappeared! No matter how hard the experimenters work, the interference fringes will no longer appear!
As soon as people observe, electrons move in the form of "particles"; if people do not observe, electrons pass through the double slits in the form of waves, causing interference, resulting in stripes!
Does the Creator really exist, and electrons also have ideas, and this problem keeps bothering scientists! In 1979, the 100th anniversary of Einstein's birth, a seminar commemorating him was held in Princeton, where he worked during his lifetime. At the meeting, Einstein's colleague and one of Bohr's close collaborators, John Wheeler, proposed a rather surprising concept, which is the so-called "delayed double-slit interference experiment."
That is what happens if we quickly put the camera on the back board based on the speed of the electron, after we determine that it has passed through the double slit?
5, University of Maryland announced that the experiment had been successful. The result was that after we confirmed that the electrons had passed through the double slit, the result was that there was no interference fringe! Vice versa, if the camera is removed quickly, interference fringes will appear, even when we decide to remove the camera, the electrons have already passed through the double slits!
That is to say, no matter whether a single electron passes through the double slit, as long as we have the idea of implementing and this behavior, there will be no interference and the stripes will not appear.
Is it a camera that affects the behavior of electrons, or does it affect the behavior of human consciousness? Or, it is really the Creator who doesn’t want humans to discover the laws of operation of this universe!

As soon as the experimental results came out, it immediately caused a sensation in the scientific community. It can be said that it completely subverts our understanding of the world. Is the world or the universe really conscious?
Or even if the past phenomenon has occurred, the addition of the camera will change the process, which means that the future changes the past, that is, human behavior will change the past process, so as not to affect the future results! Whether it indicates that our actions interfere with the universe's past, thus allowing the universe to operate in its established orbit.
When science rises to a certain angle, it immediately becomes philosophy!
. Scientists decided to ascend this experiment to the cosmic angle. Scientists observed that a star million light years away emits photons in the direction of the earth, and it will experience a galaxy of huge mass. According to Einstein's theory of relativity, this galaxy will cause space expansion and then bend light. This galaxy is actually equivalent to a huge spectrometer that divides photons into two paths: upper and lower.
. On the far right earth, we set up two telescopes to align the upper and lower light paths respectively. Then each telescope will observe photons as particle properties, and there will be no interference pattern, because the photons either bypass from above or from below.
Scientists propose that using telescopes, optical fibers and other tools to lure photons on both paths to the delay experimental device, thereby completing the interstellar version of delayed double-slit interference experiment !
However, at this time, each telescope will observe photons as particle properties and will not interfere with patterns, because the photons either bypass from above or from below.
If we use a spectrometer to combine light from the upper and lower directions, we can get the diffraction pattern of the photon itself again. In theory, yes. Photons traveling all the way as particles cannot produce diffraction patterns, they must be waves.
You should know that they have set out in millions of years, and their journey has been decided long before they set out. In other words, when humans decide to observe them, the journey route they decided millions of years ago has changed!
Wheeler Later quoted Bohr as saying, "Any basic quantum phenomenon is a phenomenon only after it is recorded." Whether we make a decision before or on the way is made, this is no difference in quantum experiments. History is not certain and real—unless it has been recorded. More precisely, where is the photon "actually" between passing the first lens and when we insert the second lens, it is a meaningless question. We have no right to talk about it. It is not an "objective truth"! Wheeler used the famous "dragon picture" to illustrate this point. The dragon's head and tail (input and output) are both certain and clear, but its body (path) is a fog that no one can tell it clearly.
However, Wheeler's explanation still did not clear away the fog shrouded by this experiment, and even the Copenhagen explanation is a hypothesis waiting for verification. The horror of the electronic double-slit experiment is that it breaks the authenticity of the world. Everything you see is not the real way. The world changes every second. consciousness will determine what you see . It is a mystery to see the illusion of this world that is produced and exists in this way!
In addition, it also makes us think about whether there is really a Creator in this world. It has set an established operating rule, which does not allow anyone to spy on it, nor can anyone break it. Once human ideas arise, they will change in the past, thereby correcting the final result!
The mystery of the double-slit experiment has not been understood yet~
