What is the unsolved scientific question in the world right now?

Why people came into this world.

Quantum mechanics is a recognized scientific discipline, but the "wave-particle duality", "uncertainty principle" and "Schrödinger's cat in the cat" in quantum mechanics, as well as "quantum entanglement", are all not explained clearly by science, Einstein can be said to be the founder of quantum theory, he also does not understand quantum mechanics, and said, "God does not roll dice", and even the physics community once said that only two and a half people understand quantum mechanics.

The biggest problem with quantum mechanics is that its scale is too small to be measured by science today. As a result, "observation" affects the measurement results, seems to introduce the power of thinking, and avoids the intervention of consciousness, and as a result, quantum mechanics cannot study the "small quanta", and can only rely on statistics. However, quantum is inherently small, and if we don't study its "smallness" and don't consider "individual quantum", is it still quantum mechanics?

And when the boundaries of the "small" are opened, it is clear that the "ghost" of consciousness appears.

The objectivity of science is independent of the interference of consciousness, and when consciousness enters the first part of the study, can consciousness still be distinguished from the interference of consciousness? The jury seems inconclusive, and it seems that the object is a paradox.

The mystery of transportation.

The most pressing and practical problem is the issue of transportation. Even with enough manpower, it would not be possible to transport the boulders from tons to 160 tons to the construction site. With a car?

With horse-drawn? No way! There were no horses or chariots in Egypt at that time.

The chariot and horse were introduced from abroad in the 16th century BC, 1,000 years after the construction of the Great Pyramid of Khufu.

Some people think that it is carried with a pry board round wooden stick. But this method required the consumption of a large amount of wood, and the main tree in Egypt at that time was palm, whether it was the quantity, growth rate, or hardness of the wood, it was far from meeting the needs of transportation, and it was almost impossible to import wood.

Some people think it's the water transport law. In 1980, the chief inspector of monuments in Giza, Egypt, Hawas, took core samples and dug to a depth of more than l00 feet, and found a rock wall at least 50 meters deep, which may have been a port dug during the Fourth Dynasty of Egypt. Later, a waterway connecting to the port was discovered.

However, without pulleys, winches, and sufficiently advanced lifting equipment, it is more difficult to make such a bulky giant stone go downhill, on the boat, and on the shore than to skid it on land. What's more, there is at least a 50-foot drop between the water surface and the rocky shore! And the pyramids on the west bank of the Nile have to be made of stone on the east bank of the Nile!

In addition to land transportation and water transportation, they can't do it by air?It's a mystery.

A French industrialist, who studied the pyramids from a chemical and microscopic point of view, believed that these stones were not integrated, but a mixture of lime, rocks, shells and other substances. Because the adhesive used has a strong coagulation force, it is almost impossible to tell whether it is a natural stone or an artificial stone. This, of course, can appropriately solve the problem of transportation difficulties.

However, as circumstantial evidence, the centimeter-long human hair found in the stone is still too little; And this outstanding adhesive is not only not recorded in ancient books, but also the chemist has not yet analyzed it with modern means.

Today's science is not omnipotent, there must be many scientific questions that have not yet been answered, so you need to increase your knowledge and understand more knowledge, maybe you will have the opportunity to answer these questions, and you may be the next Nobel Prize winner!

How many mysteries in this world cannot be explained by science?

Since ancient times, there have been many problems that cannot be explained by human beings, and many of them are classified as theology, and these things are called supernatural phenomena in the scientific community, but there is still no way to explain the occurrence of these problems. What does the two seem to be related, ghosts may live in parallel universes, there is no direct evidence for these questions, everything is everyone's constant speculation, there are three such events on Earth, they claim to be reincarnated, is this true?

1 A girl dreamed of her younger brother, in the dream her brother told her that she was killed, in the dream the younger brother told her sister where his body was, and then his sister called the police, the police according to the place mentioned by the sister, successfully found the body of the younger brother, and found the suspect through various schemes, and so far the police are more surprised what the situation is, her sister said that she only had a dream, and in the dream it was all her brother who told her.

2 This man claims to be reincarnated, and there is a folk saying that after his death, he will be reincarnated and drink Meng Po soup, and Meng Po soup will make him forget all the memories of his previous life, but there are still many people who claim to be reincarnated. A man who claimed to be reincarnated, his name was Chen Mingdao, and he was able to clearly tell all his experiences in his past life, including where his parents were in his previous life.

3 In addition to Chen Mingdao, in a small mountain village in Sichuan, many of them claimed to be reincarnated from their previous lives, and they were able to open their mouths to tell their experiences in their previous lives. Some people think that it was made up on purpose, but we have no way of knowing what the real answer behind it is.

4 In 1932, a man named Sergei, he mysteriously appeared on the street, and then mysteriously disappeared, originally under everyone's surveillance, but he could also mysteriously disappear, and then there was no trace of him, some people said that his mysterious disappearance was to travel to another time and space, and traveling through time and space is a complex means Is it really that easy?

5 About these mysterious phenomena, scientists have been looking for answers, trying to unravel the mystery of these mysterious events, it is estimated that there really exist parallel universes and reincarnation in this world, but it is difficult for us human beings to see with the naked eye, and when human science and technology mature, after reaching a certain stage, they may be able to solve the answers behind these questions one by one.

A large number of facts have proved that there are indeed supernatural things happening in this world. It's just that human technology is insufficient, and it is difficult to discover a mystery. In addition, human beings have not yet been able to enter the four-dimensional space well, and now there are only three dimensions.

So, the problem that can't be explained, let's just say it doesn't exist, don't you think it's a kind of self-deception Some time ago, a news of "Chongqing Fengdu "Ghost Town" Family of 4 Died Early One After Another" caused netizens to discuss whether the supernatural exists. The report speculated on the cause of death of the family of four from various scientific perspectives, but there was not enough evidence to convince readers that it was "pure coincidence." So, do supernatural beings really exist?

In the face of the emergence of more and more unknown phenomena in the world, scientists are also trying to explore the causes. Therefore, this poop tire has been set up for everyone, and netizens can express their views on the "supernatural events", and they can also write out the "supernatural events" they have experienced to share with you. Positive view:

There are many special phenomena in this world, but the so-called "supernatural" does not exist. We admit that there are indeed many objective phenomena that cannot be explained by common sense and modern science, such as prehistoric civilizations and UFO phenomena, but with the progress of science and technology and the expansion of cognition, we believe that these phenomena will eventually be overcome by science. For example, when people thought that ghost fires were lit by ghosts, they actually burned phosphorus in the air.

The vast majority of "supernatural events" are nothing more than hearsay, without factual and scientific basis. So the so-called supernatural in this world does not exist. Counter-view:

Paranormal phenomena are often associated with the movement of life. In fact, the existence of paranormal phenomena has been confirmed not only by the personal experience of many people, but also by many well-designed scientific experiments. Many scientific studies have continuously confirmed the existence of "human peculiar phenomena".

The common denominator of this kind of "human body-specific phenomenon" is "objectively existing that cannot be explained by modern science, is directly related to consciousness", that is, the "supernatural phenomenon" we are mentioning here.
