Scientists put forward the "dandelion conjecture", indicating that the universe is full of life, but humans can't find it
Looking at the entire universe, only the earth has life at present. There are two possibilities for this phenomenon. One possibility is that there are other life forms in the universe, but human beings have not yet found it, and the other possibility is that there is no existence in the universe except the earth. other life. Compared with the second possibility, most scientists who study extraterrestrial life prefer the first possibility, because the exploration ability of human beings is still very limited, and a conclusion cannot be drawn because the temporary search is fruitless.

The 5 most plausible pyramid building theories
One of the most perplexing mysteries in human history is how to explain the incredible engineering feat that went into the construction of the Great Pyramids of Egypt. For thousands of years, historians, architects and scientists have tried to find the best explanation for these massive structures. To this day, the mystery has not been fully solved. No one really knows how it was done. But many explanations have been offered, and we will test the five most plausible theories for the construction of the Great Pyramid.

Earth’s History: A Timeline of the Earth’s Life
Today, Earth is a dynamic, living planet. It has an atmosphere that cycles between carbon dioxide and oxygen levels, it has an ocean that teems with life, and it has the right temperature and gravitational pull to support life as we know it. But there was a time when our blue planet was very different. We know this because we can see the remnants of Earth’s earlier history in the geologic record. The story of our planet’s transformations is preserved in rocks and fossils, which provide clues about what happened billions of years ago. Understanding Earth’s past helps us understand our present and anticipate its future.

Interesting Facts About Earth
You’d be forgiven for thinking that we know everything there is to know about Earth. It’s the planet we all call home, after all, and one that has been extensively studied by scientists over the centuries. However, even though there are plenty of books and articles out there that tell us interesting things about our planet, there still seems to be so much more to discover about it. You might think you already know everything worth knowing about Earth — but these facts will prove you wrong! Read on for some amazing insights into our home planet that you probably didn’t know.

How was the mass of the Earth measured? It's a long process of calculation that began in ancient Egypt
What is the mass of the Earth? It is about 5.965 times 10 to the 24th power of the kilogram. This result can be easily obtained by searching, but many people may have doubts about how this number was obtained. We know that the earth is a very irregular sphere, and this sphere is composed of a large number of different substances, on the surface, there are oceans, mountains, deserts, swamps, and below the surface, there is a layered structure composed of the crust, mantle and core, such a sphere where the mass of each part of the material is different, how can we accurately calculate its mass? It is a long process of calculation, the beginning of which can be traced back to the ancient Egyptian period.

The Loch Ness Monster is the world's most mysterious and famous unknown creature, in recent years to explore the most likely to be what?
Loch Ness is located in the Great Glen in the northern part of the Scottish Highlands in Western Europe, the area of Loch Ness itself is not large, but it is very deep, the average depth of more than two hundred meters, the deepest of which is close to three hundred meters at the bottom of the lake. Loch Ness year-round water temperature is very low, but it is strange that the year-round does not freeze will not freeze. And the water in Loch Ness is very turbid, full of coal sludge, visibility is also very low. All these conditions laid the foundation for the subsequent world-famous Loch Ness.
