Mars can grow vegetables, Trailblazer finds lots of organic matter
Recently the news that NASA's Perseverance rover found a lot of organic matter on Mars was searched, which inevitably reminded everyone of extraterrestrial life. Some people even asked the question of the soul: Can we grow vegetables on Mars? Or can we grow vegetables with Martians? If the story in the movie "Mars Rescue" really happened, can astronauts grow potatoes directly from Martian soil?

A 'door' found on Mars, a portal to Martian civilisation? Here's the scientific explanation
For decades, people have been exploring Mars. In the process, they have discovered many valuable clues to some of Mars' origins, geological structures, and features. But the exploration of Mars is still limited. The Mars rovers Ely and Zhu Rong are currently still working on Mars, hoping to bring back more useful information. Recently, the Curiosity rover took a controversial photo on Mars.

Is it a coincidence? Why did the satellite pick up the signal again after years of being "lost"?
Previously launched a satellite, was launched more than forty years ago, to now also lost for more than forty years, just two years ago, suddenly transmitted a data signal biologists received this should be very incredible let people happy, according to the biologist's research found, but not happy at all can not afford.

Why do organisms generally become larger in oxygen-rich environments?
The day before yesterday Hays Wolf Mountain (Wolf Mountain, Hun) had mentioned that the current atmospheric oxygen content of the Earth is only 21%, but this is not the era of the highest atmospheric oxygen content in the geological history of the Earth. The era with the highest oxygen content in the Earth's geological history is thought to have occupied 27% to 28% of the atmospheric content of oxygen, which is more than 30% of the oxygen content above today's sea level. There are thought to have been two possible peaks of this oxygen enrichment. One occurred in the Carboniferous period between 360 million and 300 million years ago. Plants at this time grew particularly large because of the oxygen enrichment. Ferns were often tens to hundreds of meters tall. The death of these giant plants produced a huge accumulation, which is the largest source of today's coal strata, hence the name of this era, the Carboniferous. Another peak of oxygen enrichment may have occurred 200 to 140 million years ago in the Jurassic period, when the world was covered with giant reptiles, becoming the most prosperous era of dinosaurs. Therefore, once the Earth was enriched with oxygen, both plants and animals would increase in size massively in parallel. This has been the basic consensus. But the problem is that

Science: Curse Or Blessing?
The conceptual satisfaction of a person is achieved through religion, philosophy and finer literature. However the practical satisfaction of human needs is fulfilled through technology, basic and advanced. Science is the knowledge that bridges the gap between conceptual and practical fulfillment of diverse human needs. In addition, science gives authenticity to religious, philosophical, literary and technological works. It rectifies the deficiencies of all. Science may prove a good and faithful servant if we use it wisely and carefully.

What kind of people have the ability to open the eyes of heaven?
There is a legend that "the sky opened its eyes", referring to the sudden appearance of mysterious bright light in the sky. As the Yuan Dynasty Yao Tongshou "Lejiao whispers" cloud: "when the dawn star is still under the tree, suddenly the southwest sky cracked several feet, light flames like a fierce fire, shining all over the field. At that time, the village dogs were barking and the birds were flying. Yu Shizi looked at its crack, astonished, in the recovery of great clarity. If it is the smelter land funds. Hours together the man who operated the boat said to Yu: the sky opened its eyes. Some scientists say it is "aurora borealis", but the aurora borealis will only appear in the high latitude areas near the North and South Poles, many ancient books on the record of the opening of the eyes of the sky, all occurring in low latitude areas, which is a supernormal phenomenon, can not be explained by the aurora borealis.
