A strange phenomenon that has puzzled physics for a century

In our daily lives, we occasionally encounter all kinds of strange phenomena, phenomena that are difficult to explain scientifically. But we shouldn't be too surprised, because science is evolving all the time, and some of the weirdness is just not there yet, or we're having some kind of delusion.

And in the quantum world, it's really weird, so weird that we even start to doubt life, doubt the reality of our world.

Quantum entanglement, for example, means that two entangled quanta, no matter how far apart they are, can instantly sense each other, even at opposite ends of the universe, which is so contrary to our common sense.

Even weirder is the double-slit electronic interference experiment, an experiment that upsets our world view, where what we observe affects the results.

The experiment itself is not complicated. An electron-emitting gun with two slits behind a screen for receiving electrons.

In our minds, electrons are real particles, so when they pass through two slits in the baffle, they appear as two stripes on the screen.

But the surprising result was that instead of two stripes, the screen showed multiple interference stripes, which baffled the scientists.

Since the appearance of interference fringes means that electrons are no longer actual particles, but also have the characteristics of waves, a single electron can pass through both slits at the same time, and then interfere with itself!

How is this possible? How can a single electron pass through both slits? But the results have to be accepted.

So scientists probe near the damper installed, want to have a look at how electronic at the same time, through the two slits, but don't see it doesn't matter, when scientists opened the detector, electronic seem to know that someone was watching it, "darling" to show the characteristics of particles, one by one through the slit, presents two stripes on the screen, there will be no more than is interference stripes.

Does our observation affect and change the state and behavior of the electron? How is it possible to rise to the larger world, as if my observations affect your behavior?

If you look at an electron, it behaves like a particle. Without looking at the electron, it behaves like a wave!

No wonder Einstein was also confused and asked: Does the moon not exist when you are not looking at it?

Quantum mechanics has been developed for more than a hundred years, and there is still no perfect interpretation. At present, the mainstream explanation is the "uncertainty principle" of the Copenhagen school. In the quantum world, everything is uncertain, cannot be accurately described, is fuzzy, and can only be described by probability.

And want to make uncertainty into certainty, only two words: observation! Nothing is certain until observations are made!

Normally, electrons appear as "electron clouds", which are packets of energy whose trajectories cannot be seen; In the double slit experiment, electrons appear as particles. The results of these two experiments show that the wave-particle "duality" is only a superficial phenomenon. It relates to the fundamental question of the nature of space and time. Quantum scientists, and Einstein himself, were stumped. Some of the later, official scientists approached theology, and some were wrong. If it is wrong, there should be arguments to prove that none of these have been presented. In fact, the electronic experiment illustrates a problem, the nature of the universe of space and time. Who can explain the correctness of the wave-particle "duality", who is an Einstein-type tall man.

In the quantum world, everything is uncertain, cannot be accurately described, is fuzzy, can only be described by probability." The low-dimensional quantum world appears "probabilistic", while the high-dimensional quantum world appears deterministic.
