Sometimes it seems that a person has already solved all the mysteries in the world. We present to your attention 10 evidence that we know too little about the world.
10. What are the laws of the universe?
Based on the law of gravity, we can say that the Universe is preparing for "Great contraction." This reverse process of the so-called Big Bang. But the universe is expanding. Not so long ago, scientists discovered that the process of expansion of the universe is accelerating. They even received the Nobel Prize for this. Only a few years later did other scientists doubt the veracity of this standard concept. The debates of "pundits" do not subside. They can’t get to the bottom of the truth and don’t know what happened to our Universe and what awaits it in the future. Ordinary people do not care much whether the Universe is shrinking or expanding, but now they at least possess general information, and do not believe that the world stands on three elephants.
9. Why did life appear on Earth?
No one knows where life came from on Earth. 3.8 billion years ago appeared ribonucleic acid, which contains the cells of all living organisms. Of course, there are more than enough versions of the appearance of life on Earth. The most common are God's creation and the influence of ultraviolet rays. No matter how hard the scientists tried, whatever version they put forward, they did not find an answer to this question. Perhaps that is why, in the age of technological progress, some still believe that God or alien civilizations founded life on Earth.
8. Mysteries of dinosaurs
At first glance it seems that people know a lot about dinosaurs. They can be seen not only in feature films, but also in popular science films, not only in books of an entertaining nature, but also in encyclopedias. However, most of the information presented there is nothing more than the fiction of scientists. True, they are based on what we managed to find out. Researchers usually find small fragments, dinosaur remains, and then try to restore its appearance from them. So until now, scientists cannot answer the question of what the first dinosaur was, whether they were cold-blooded or warm-blooded, how they created pairs, how they hunted, and why nature rewarded them with such large sizes. Perhaps someday, thanks to new technologies, scientists will be able to find out the answer to all these questions.
7. Why do we sleep and why do we dream?
This is what excites not only scientists, but also all other people on Earth. They do not understand why we sleep, how dreams appear, and why they are. Sleep is a person’s physical need. The Guinness book recorded a record: a person did not sleep for almost 19 days. He had many health problems, in particular mental illness. Dreams, according to scientists, can prevent psychosis. But this is only one point of view. In fact, there are a lot of them. Someone claims that dreams are based on events already experienced by man. Someone believes that these are unrealized versions of events. Someone is sure that dreams will come true soon. These are just assumptions.
6. What happens after death?
Another issue that concerns not only scientists. What happens when a person dies? According to the Orthodox religion, after death, the human soul goes to heaven or hell. There are other versions. According to one of them, the human soul from 1 to 40 days after death is able to return to Earth, during which time it must solve unresolved problems. After 40 days, she must go all the way from the end to the beginning and get rid of all karmic debts. Further, the soul is placed in a casual body (Spirit). Then a number of events take place, as a result, the soul is ready for a new incarnation. It is not known whether this is true or not, for the dead do not return and cannot tell what happened to them. But based on studies on the study of clinical death, it has been suggested that human consciousness continues to exist after death.
5. Theories about the world are changing all the time.
People are quite self-confident creatures, and very often they think that they are aware of everything that has happened and is happening in the world. Each time period has its own theory, which later turns out to be ruthlessly defeated by other discoveries of scientists. In antiquity, the earth was represented as a flat disk or half an egg floating in the sea. Then scientists recognized that the Earth is motionless. Their followers refuted this theory. They claimed that all the planets move around the sun. The descendants supported them, but added that the stars and the moon revolve around the earth. Only in the twentieth century, scientists were able to make a plausible picture, because at their disposal appeared telescopes, computers and other equipment. Man traveled to outer space. But it is possible that in a few years this picture will change.
4. Why does man need art?
Since the world appeared, people have been engaged in creativity. About 30 thousand years ago, the first cave paintings appeared. Then people began to make figurines and figurines. But if you ask a modern person why he needs it, he is unlikely to be able to clearly answer. Beautiful phrases about self-expression do not count. Some scholars suggest that art was invented to attract individuals of the opposite sex. That is, the instinct of procreation "worked" here. True, this or a wild fantasy no one will say now. However, people are so accustomed to the existence of art that they cannot live without it.
3. Mysteries of the story
It seems to man that he knows everything about history. This subject is taught at school. That's just many events have not reached our times, some of them are greatly distorted. Take at least the history of Russia. There is no consensus on where the name Rus came from. No one can answer whether the Mongol-Tatar yoke really was. There are many opinions on this subject, but not a single plausible answer. Have you ever wondered why Peter I tried to remake Russia in a European way? But historians suggest that he was replaced when visiting European countries. The real king was killed, and in return they sent a foreigner. Many controversial questions, the answer to them is unlikely to be able to find.
2. Ancient literature
Despite the fact that literature has existed for a long time, very few ancient works have survived to this day. Moreover, nothing is known about the writers. So even about the famous Shakespeare, who is being read now, no one can say anything. There are suggestions that it did not exist at all, allegedly a group of playwrights worked under this pseudonym. And Old Russian literature was generally not created for entertainment. She told about religion, about important people, about some events in the state. Those works that are accessible to the modern reader reached him with significant omissions and distortions. Only in the 18th century did creations appear that can be attributed to fiction.
1. The force of gravity
This is perhaps the most difficult puzzle for scientists. Everyone knows that it is gravity that keeps a person on the surface of the earth. Larger objects can attract smaller ones. While scientists figured out where gravity comes from, they came to interesting conclusions. Now they doubt whether it exists at all. In any case, at the current level of science, the answer to this question cannot be found, as, indeed, to many other questions. Maybe in the future, humanity will be able to learn the truth, but it certainly will not happen soon.
