Scientists have been interested in the structure of the Universe and life in it for many years. Unfortunately, some questions have not yet been answered. Experts have compiled a list of ten mysteries that humanity has yet to solve.
1. Every person on Earth is endowed with consciousness and subconsciousness - these phenomena were described by Sigmund Freud. Until now, the mechanism of the formation of consciousness and its influence on a person have not been fully studied. Different scientists have their own hypotheses, but none of them has found scientific confirmation.
2. Every night a person sees dreams, whether he remembers them or not. Dreams are the work of the conscious and unconscious beginnings. How exactly dreams arise and for what reason a person sees what he sees is not clear. The secrets of dreams are studied by the special discipline oneirology.
3. The existence of intelligent creatures similar to humans in the Universe has not been proven either. Despite numerous attempts to contact "neighbors", no signals from other civilizations have been received to this day. Considering the scale of the Universe, it would be foolish to think that there are no other "humanities" in it, but so far the presence of aliens in space has not been proven, except for the dubious UFO pictures that are now and then posted on the Web by amateur ufologists.
4. Scientists have long understood that the Universe contains all the elements of Mendeleev's periodic table, but they failed to understand the essence of dark matter, the most common, according to astrophysicists, matter in space. Scientists are actively investigating this phenomenon, but so far to no avail.
5. The origin of life is one of the most interesting mysteries of the Universe. There are several theories of its origin, but none is scientifically substantiated to the end. Believers claim that life is the result of the activity of a certain deity, while astrophysicists are sure that it came to Earth from space. Where did life come from in space is another unanswered question.
6. People have not studied not only the Universe - there are also many secrets on Earth. For example, it is still unknown what is at the bottom of the ocean. Most of the planet is covered with water, but this environment has been studied by no more than 10%.
7. The riddle of prime numbers is also of interest to humanity. To this day, the regularity of their location in the natural row has not been proven.

8. The issue of excess carbon on Earth is one of the most important problems of our time. In the 21st century, most people have cars that give off exhaust fumes. In addition, thermal power plants have been built in many countries - they also emit huge amounts of carbon monoxide into the atmosphere. How to get rid of the excess of this naturally occurring chemical element remains to be seen.
9. The secret of the boundary of the Universe and the existence of other universes is also not revealed. Presumably, the universe has no boundaries, but if they are all tin, what is behind them? Science has yet to provide any satisfactory answer.
10. Everyone knows what black holes are, but no one knows what happens when a space object gets there. Some astrophysicists are of the opinion that, flying into such a hole, the body falls into another time dimension. Of course, no one can prove this.
