The world is full of mysteries, and scientists are very passionate about exploring the universe. Although today's technology is developed, the universe is vast. Thanks to existing technology, we still can't solve some of the mysteries in the universe. In fact, there are many wonderful phenomena not only in the universe, but also on Earth that scientists have not been able to give answers to this day. It has been 4.6 billion years since its birth. In this long process of development, many lives have gradually been bred on the earth. In the process of evolution, some organisms will continue to grow, and some will disappear on the earth, such as the extinction of dinosaurs, and there is no scientific explanation. Many people say that the extinction of dinosaurs is due to natural selection and survival of the fittest, which seems to be recognized by the public. But scientists have also not found conclusive evidence for this claim. There are many other accounts of the extinction of the dinosaurs, such as geomagnetic reversals, climate change, ocean contraction, volcanic eruptions, etc. But so far there is no good explanation.
The world-famous "Mystery of the Dharma Triangle" also bothers people. The Bermuda Triangle extends north to the Bermuda Islands and is sent to Miami, Florida, United States. Since 1945, hundreds of planes and ships have been mysteriously missing in a triangular water in Poponic, hence the name Devil's Triangle. These mysterious and inexplicable disappearances have long been synonymous here. The mystery of the Bermuda Triangle is still widely debated. Some scientists have conducted scientific experiments on the Bermuda Triangle, and as the satellite passes over the Bermuda Triangle, they clearly feel an increase in radiation and disappear when they leave the Bermuda Triangle. For the Bermuda Triangle, scientists believe that the disappearance mystery that appears here is a supernatural phenomenon with aliens. Some people have proposed that there are abnormal whirlpools in the bermuda triangle, that there is a bubble theory, that the ocean floor is hollow, and so on, which is still an unsolved mystery.
Third, the unsolved mystery is the Egyptian pharaoh city. Egypt has long been a mysterious country, and the people of this city once lived a rich and comfortable life, and people lived very happily. I don't know when it started, everything here will disappear. The civilization of the Pharaonic city-states disappeared overnight. Many scientists and archaeologists come here to do survey work. But there was no progress, and the Pharaonic civilization seemed to have never been to this world without a trace.
The last point I would like to make is the mysterious sail stone, which is scattered across the salt lake at the racetrack in Death Valley, USA. Could someone here think it's a rock? What's so strange about that? The stone was not strange at all, but strangely enough, without the intervention of creatures such as humans and animals, they would mysteriously move on their own on the wasteland, leaving traces of walking on the ground. Some scientists believe it is caused by strong winds. But some scientists believe that these foods weigh enough to be compared to human weight, making it very difficult to move. This sail stone has different theories, but still no one can understand.
In fact, there are many things in this world that we cannot answer. But the history of mankind is moving forward, and I believe that one day our science and technology will be more developed. Then, solve these difficult problems one by one.
