It's no secret that outer space is full of unexplained mysteries and unsolved mysteries that continue to trouble the minds of scientists trying to find logical answers to them. From mysterious dark matter to the multiverse, the truth behind these mysteries may be more amazing than the most incredible fantasy!
1. THE SIZE OF THE UNIVERSE
Many scientists and researchers are trying in vain to find an answer to this question, however, unfortunately, everything remains at the level of several hypotheses and assumptions. To find a clue to the mystery, scientists studied a huge amount of information. Starting with the solar system, they discovered a myriad of new questions that have led them further into a dead end.
Trying to decipher the solar system, scientists have discovered that there are more than 200 billion solar systems in our galaxy alone, and there may be about 150 billion galaxies in the universe. Imagine how crazy and incredible a particular result can be! However, Oxford University researchers believe the universe is at least 250 times its intended size - and that's only for galaxies, let alone planets!
2. BLACK HOLES

Black holes are one of the most mysterious mysteries of the universe. Some scientists believe that the structure of black holes resembles the structure of galaxies, and they are characterized by very high and powerful levels of gravity, capable of absorbing everything, including light.
Even more interesting is that in the Milky Way alone, scientists admit the existence of about 100 million black holes, but how they form, how they function and what happens when matter gets into them remains a mystery.
3. WHAT HAS APPEARED EARLIER - A BLACK HOLE OR A GALAXY?
Another question that concerns scientists - which appeared first - black holes or galaxies? Based on the results of studying the radio frequency spectrum, black holes were the first to exist. According to the researcher at the US National Radio Astronomy Observatory Chris Carilli, first black holes appeared, and only then stellar galaxies formed around them.
4. DARK MATTER
Dark matter is another mystery that we have no idea about. Hoping to get to the bottom of the truth, scientists put forward a variety of assumptions and assumptions, but the only thing that they found out is that dark matter is a substance that functions like a spider web. They also concluded that this substance can account for up to 25% of the entire universe. Dark matter exists and there is a lot of evidence for this, but what exactly it is remains a mystery.
5. TEMPERATURE OF DARK MATTER
Scientists are trying to understand not only what Dark Matter is - they are interested in how cold or hot it can be. Various theories suggest that dark matter can be hot, warm or cold, but the Lambda-CDEM model is generally accepted, according to which this substance is cold and dark.
6. DARK ENERGY
In the 1990s, a group of astrophysicists called dark energy a substance that, in their opinion, counteracts gravity and accelerates the expansion of the universe. Scientists believe that dark energy makes up almost 70% of our unknown and mysterious universe. According to some theories, dark energy is a region known as "quintessence" - the concept of a scalar field that is variable in time and space, proposed by Einstein.
7. NEMESIS IS OUR SECOND SUN
Some of the secrets of outer space are very difficult for the human brain to perceive, if not impossible. So, many scientists believe that once we had two suns, one of which bore the name of Nemesis.
Astronomers believe that since 80% of star systems are binary, there is a possibility that the sun was once binary as well. Surprisingly, recent research confirms this, because as a result of a detailed study of the stars of the Milky Way, scientists have come to the conclusion that all sun-like stars are born in pairs. Nevertheless, until a star is found that is identical in composition to our sun, Nemesis will remain one of the most mysterious mysteries of the universe.
8. MOON
No one really knows where the moon came from. Despite numerous studies, the answer to this question has still been found and everything remains at the level of theories and assumptions. Some popular theories assume that the Moon appeared as a result of a giant collision of the Earth with a "protoplanet" that occurred about 4.5 billion years ago.
Another popular theory suggests that the Moon is actually an asteroid stuck in our gravity.
9. NOISES OF SPACE
The sound of the Universe is inaccessible to the human ear, because in the conditions of space, molecules of matter do not collide with each other and do not create the vibration that is usual for our eardrum. Nevertheless, the sound of space exists and can be determined using radio signals, but scientists cannot explain where it comes from and what causes it.
10. SPACE RAYS
Cosmic rays are high energy particles moving through outer space. The intensity of cosmic rays increases markedly and substantially. According to California Institute of Technology scientist Richard Mewaldt, in 2019 the intensity of rays increased by 19% - a value recorded for the first time in 50 years.
