价值700亿亿美元小行星被发现，平均每人930亿，为何无人开采？
Asteroid worth $70 billion found, but no one is mining
Introduction: With the continuous development of the economy, various countries have gradually withdrawn the banknotes belonging to each country for the sake of economic stability. The banknotes implemented by various countries have their own values, but if we say that the world is universal, it should be gold. Gold is a very precious metal on earth, and because gold is relatively rare, its value preservation rate is also very high.
After years of development, scientists have also tested and roughly estimated the earth's metals, and finally found that there are not many gold mines available for mining on the earth. In fact, there are many theories about gold mines. Some people once speculated that there are a large number of gold mines in the ground of the earth. Later, scientists also explored and finally found that there are indeed rich gold mines in the depths of 10,000 meters underground. In addition, some planets in outer space also carry some gold, so why don't humans mine gold mines in the ground or asteroids?
gold in the core
The core is located tens of thousands of meters from the surface. According to the investigation of scientists, it was found that the temperature of the core is 5500 ℃, and the pressure is 3 million times that of the surface pressure. It's these two simple numbers and people know why they don't mine. First of all, the high temperature of 5500 ℃ will cause the mining machinery to melt, and the gold will become a huge solid after high temperature and high pressure, so it will be very troublesome to mine.
There are also some magma or rock zones between the surface and the core itself. Even if high temperature and high pressure are not considered, the hard transition zone will damage the drilling tools. And when excavating the earth's core, it will first pass through the mantle, and the mantle layer contains molten substances such as magma. If human beings insist on mining regardless of the safety of the earth's surface, it will easily lead to volcanic eruptions and cause serious damage to the earth's environment. harm.
Excluding some risk factors, it takes a lot of human, financial and material resources for humans to dig tens of thousands of meters. The most typical example is the Kola Pit in the Soviet Union. At that time, the Soviet Union and the United States were in a military competition. In order to cope with the competition of the United States, the Soviet Union also began the "digging through the earth" plan. Although the Soviet Union invested a lot of material and financial resources, it ended up with insufficient funds.
At that time, the Soviet Union excavated 12,262 meters, but this distance was still a long way from the core of the earth, and after the Soviet Union excavated 12,000 meters, the remaining 262 meters took 10 years. Although current science and technology have made progress, it can be said that human beings want to dig to the core of the earth. Even if humans have dug to the core, mining and transporting gold is a huge problem.
"Gold Mine" in Space
In addition to the large amount of gold deposits in the earth's core, many planets in space also contain gold. Scientists once found a planet called "Spirit Star" containing various metals. Although there was no trace of gold on the planet, the content of iron was very high. According to scientists' calculations, " The metal value of Lingshenxing has reached 70 billion US dollars. Even if it is given to everyone on the earth on average, then everyone can share 93 billion US dollars.
Conclusion:
Although the value of "Spiritual Star" is very huge, it is unrealistic to extract the metal on "Spiritual Star" with the current technology of human beings. Nowadays, the gold mines in the core of the earth and the metal mines on the spiritual star cannot be obtained. Therefore, in addition to finding ways to find various metal substances, human beings should also develop the habit of saving or efficient use, because in this way, the Only matter can support us to go further.

The new view shows that there is still a "sun" in the solar system, which is the companion star of the sun
This is an amazing find! At a distance of 86.8 light-years from the earth, there is a sun-like star called HD4712B. Its mass is similar to that of the sun, only about 1.02 times that of the sun, which also makes this star and the sun similar to the sun. The same, is a yellow dwarf.

Tiny Lion Cubs Struggle To Keep Up With Mom
In the heart of the African savannah, life is a constant lesson for young animals. Few scenes are as endearing — or as heartwarming — as tiny lion cubs trying to keep pace with their mother. These little bundles of fur face a world full of challenges, from learning to hunt to avoiding dangers, all while depending on the guidance and protection of their experienced mom. Watching cubs wobble and tumble as they attempt to keep up with their mother reminds us that growing up, even in the wild, is a journey full of struggle, determination, and adorable missteps. The Early Days of Lion Cubs Lion cubs are born blind and helpless, usually in litters of two to six. For the first few weeks, they rely entirely on their mother for warmth, food, and safety. Even after opening their eyes and beginning to explore, the cubs are far from independent. The first months are crucial. Cubs learn social cues, hunting basics, and survival skills simply by watching their mother and the pride. But as anyone who has observed them knows, there’s often a huge gap between observation and action. Tiny cubs often struggle to match their mother’s pace, especially when she moves through long stretches of savannah or leads the family on patrols. A Mother’s Role in the Wild For a lioness, raising cubs is a full-time commitment. She hunts, defends her territory, and teaches her young, all while staying alert to predators such as hyenas, leopards, and even rival lions. The cubs, meanwhile, attempt to mimic her every move — often with clumsy yet charming results. A mother lion’s patience is remarkable; she frequently slows down, nudges them along, or stops to ensure no cub is left behind. These moments, while stressful for the tiny cubs, are vital learning opportunities. Struggling to Keep Up: Why It’s So Hard There are several reasons why tiny lion cubs have trouble keeping pace with their mother: Short Legs, Big Steps: Lion cubs’ legs are tiny and their coordination is limited, making it difficult to cover the same distance as an adult lioness. Curiosity: Cubs are naturally curious. A single butterfly or rustling bush can distract them, leaving mom to pause repeatedly. Energy Levels: Young lions tire quickly. Even with frequent naps, the cubs’ stamina is far lower than their mother’s. Learning Through Play: Play is not just fun; it teaches hunting, balance, and social skills. Running off to pounce on a sibling or chase an insect is all part of their education. Despite these challenges, the cubs’ determination to keep up demonstrates their resilience and growing understanding of the wild world. Lessons in Teamwork and Survival Every cub struggling to keep up is also learning crucial survival skills. The journey across the savannah is more than a test of speed — it’s a lesson in: Coordination: Cubs learn how to move efficiently across different terrains. Patience: They begin to understand the rhythms of adult life and the pace required for survival. Social Skills: Staying with the group teaches cubs how to interact with siblings and the pride, which is essential for their future roles. Observation: By following their mother, cubs study hunting techniques, territorial behavior, and predator awareness. Even the moments when cubs stumble or lag behind are essential for their development. These experiences prepare them for independence, which comes sooner than many might expect. The Cutest Moments in the Wild Anyone who has watched tiny lion cubs knows that their struggles are often irresistibly cute. Video clips from wildlife reserves frequently show cubs toddling along, tumbling over each other, or getting distracted mid-step. Observers often comment that these little stumbles reveal personality, determination, and playfulness, making them one of nature’s most heartwarming spectacles. While their mother is serious and focused, the cubs inject a sense of humor and lightness into life on the savannah. Why This Matters The struggles of lion cubs aren’t just adorable — they’re vital for understanding wildlife behavior. Conservationists and animal behaviorists use these moments to study growth patterns, social structures, and survival strategies in lion populations. These observations also highlight the importance of preserving natural habitats. Cubs must learn in a safe environment to survive; habitat loss, poaching, and climate change make these early struggles even more dangerous. Protecting the African savannah ensures that future generations of lions can experience the same lessons and playful tumbles. The Road to Independence Within a year, these tiny cubs will be more agile, faster, and more confident. By the time they reach two to three years old, males may begin to leave the pride, while females often stay and become caretakers themselves. Every misstep, tumble, and lagging moment is part of the journey toward strength, coordination, and independence. Watching them now gives us a glimpse of the challenges they will overcome, and the survival skills they will carry for life. A Celebration of Motherhood Ultimately, these scenes remind us of the incredible bond between mother and cubs. Her patience, vigilance, and teaching are the foundations of their future. The cubs’ struggles highlight the trials of growing up, while their determination showcases the resilience and beauty of wildlife. For those observing, it’s a powerful lesson in care, guidance, and perseverance, not just in lions but in the natural world as a whole. Final Thoughts Watching tiny lion cubs try to keep up with their mother is both entertaining and enlightening. It’s a story of growth, struggle, and resilience — a reminder that even the fiercest creatures start small, learning step by step. These little lions capture hearts while teaching life lessons: patience, determination, teamwork, and the importance of guidance. As they tumble and waddle across the savannah, they show us that growth is a process, one adorable misstep at a time. For wildlife enthusiasts, animal lovers, and anyone enchanted by nature, these tiny cubs are proof that even in the wild, love, care, and persistence are universal truths.

Microbiota, microbiome or microflora: how to speak correctly and why it is for health.
You've probably heard the phrase, "We are what we eat." But modern science says more precisely: we are also those who live in us. Until 2016, it was believed that there are many times more bacteria in our body than our own cells. The latest calculations by mathematicians show that we divide the body with our microorganisms by about 50/50: about 30 trillion of our cells versus 38 trillion bacterial ones.
