If there is no moon,...
We may want to be Dinosaurs II
We know that the surface of the moon is full of bumps, many of which are due to frequent meteors A crater formed by an impact. Some of these meteors were originally aimed at the Earth. If the moon had not acted as a shield, meteors would have collided with the earth, and a large number of these impacts would have been devastating to the earth.
65 million years ago, a meteorite collision led to the extinction of the dinosaurs, the previous generation of overlords on the earth. Without the moon, I don’t know how many more twists of fate the world would have had.
There may not be any human beings on the earth: there is a lack of water in the process of evolution
Life originated in the ocean, because the ocean is more suitable for life, and it is necessary for organisms to move from water to land. A very dangerous and difficult transformation. Tides offer an interesting possibility: an environment that can serve as a bridge between land and water. Many people believe that some creatures use this bridge to complete their landing-like evolution.
Among the sources of power that cause tides, the moon is the main driving force. Because the moon is closer to the earth, its gravity is greater, and its effect on tides is also greater, more than twice that of the sun. Moreover, the moon's orbit around the earth once every day will cause seawater to rise and fall twice on the earth.
Therefore, the moon naturally assumes most of the responsibility for helping biological evolution. Without the moon's gravity, the tides on the earth would be much weaker. The volume of seawater covering land and the land area covered by seawater will be greatly reduced, and the richness of life on land will be greatly reduced.
There may not be two humans on the earth: the wind is too strong
The increase in the speed of the earth's rotation has a direct impact on the intensity and direction of the wind on the earth's surface. Generally, the faster the star spins, the stronger the wind is and the longer it lasts. On Jupiter, where a day lasts only 10 hours, hurricanes resemble spinning demons and can last for decades or even centuries (other factors on Jupiter also play a role).
If the earth was always roaring with strong winds, life on earth would be a different story: tree roots would be deeper, and there would be very few branches and leaves. What about people and animals? As the earth rotates faster, there will be powerful storms and hurricanes in the east-west direction on the earth. There will be no trees on the earth, because plants must cling tightly to the ground to survive, and animals need to become stronger and have the best body shape. Aerodynamics, with natural carapace on their bodies to protect themselves from strong winds - perhaps turtle- and armadillo-like creatures will rule the Earth.
If they could evolve into advanced intelligent creatures, they would not be able to speak to each other, because it would obviously be too difficult to speak in the strong wind.
There may not be humans on Earth: the surface is lifeless
The faster a planet rotates, the more intense its surface and shallow underground activities will be. In other words, the earth's mountain building movement will become less significant because it no longer receives the additional horsepower of the moon. As a result, the various ecological environments on the earth's surface will not be as diverse as today's world.
It is still unknown whether advanced and intelligent creatures like humans can be cultivated in a simple ecological environment. Or to be more precise, there will be few mountains and few lakes on the earth. Even if humans are finally born, it will take a long time.
It may be only day or night (the seasons are the same!)
The moon is a big one among the satellites of the solar system. Among the 66 known satellites in the solar system, it is only the size of 4 Bigger than the moon. The moon's strong gravitational pull provides the earth with a force called a restraining moment, which stabilizes the earth's rotation and prevents the earth from shaking or moving bumpily in its orbit.
The different fates of Mars confirm this contribution of the moon to the earth. Mars has only two small satellites, and its rotation is unbalanced. According to calculations, the inclination of its rotation axis and orbit will fluctuate between 10 and 50 degrees.
What would happen to the world without the support of the moon? There is no doubt that the climate and seasons will lose their regularity. If the tilt of the axis of rotation were zero, there would be only one season everywhere in the world; a tilt of 90 degrees would make the world's lengths of night and day equal. Earth's 4.6 billion-year climate history will be completely changed.
Less than 24 hours in a day!
A day 3 billion years ago may have been only half a day close to modern times. During these 3 billion years, the moon acted as a reducer for the earth's rotation. The tides caused by the moon constantly wash over the earth's surface, oscillating back and forth between the sea and the land, thus creating a huge friction force that adds an additional resistance to the earth's rotation, thus greatly slowing down the rotation speed. Without the tidal tug of the moon, our day would be only 14 hours long.
Chinese people miss many festivals!
The Chinese lunar calendar is a lunar and yang calendar. The so-called lunar calendar refers to the lunar calendar (the moon was called the lunar calendar in ancient times); the so-called solar calendar refers to the solar calendar.
The first day of each month in the lunar calendar is called the first day of the lunar month (also known as the new moon or new moon). That is, the moon is located between the earth and the sun and has just passed the connection point between the earth and the sun. At this time, the sunlight reflected by the moon is Almost nothing is visible from Earth.
Similarly, on the 15th day of each month in the lunar calendar, the earth is located between the moon and the sun, so the sunlight reflected by the moon almost completely falls on the earth, and the moon phase is a full moon. In other words, the lunar calendar can accurately describe the moon's position between the earth and the sun, and the corresponding moon phase changes.
Chinese traditional festivals, except for the twenty-four solar terms, are almost all linked to the lunar calendar, such as the Spring Festival, Lantern Festival, Dragon Boat Festival, Mid-Autumn Festival, as well as the second day of February when the dragon raises its head and the sixth day of June when King Yu Birthdays, Chinese Valentine's Day, September 9th Climbing Festival, October 15th Xiayuan Festival, etc.
Just imagine, without the moon, how many traditional festivals would we lose? There is no theme of reunion with relatives, no wandering around meeting friends, and even less the sustenance of lovesickness and spiritual comfort.
Love is even more eclipsed!
In front of the flowers and under the moon, "the moon is above the willow branches, and people meet after dusk." The beautiful or sad love in the world seems to have the moon as its companion. How many shadows of the moon are there in the love you experience? Without the bright light of the moon, would those love stories that have touched thousands of years be eclipsed?
1. The most sentimental love is gone - Chang'e and Hou Yi. Chang'e is the daughter of Emperor Ku and the wife of Hou Yi. Hou Yi invited the elixir of immortality from the Queen Mother of the West, and Chang'e secretly ate it. The elixir became an immortal. After Chang'e ascended to the Moon Palace, she lived in the desolate and indifferent Guanghan Palace, missing Hou Yi. One heaven, one earth, Chang'e and Hou Yi is the most sentimental love story in folklore.
2. The most romantic love is gone - Zhang Sheng and Cui Yingying were waiting under the moonlight in the western chamber, with the windward door half open; the shadows of flowers on the partition wall were moving, and they suspected that a beautiful lady was coming. According to legend, during the Zhenyuan period of the Tang Dynasty, Zhang Sheng came to Puji Temple and met Cui Yingying. Through the matchmaker's message, Zhang Shengyue climbed over the wall at night and met Yingying, interpreting a love story.
3. Without the most sincere love - Su Shi and his wife Wang Fu lived in uncertainty for ten years. If you don’t think about it, you will never forget it. ...At night, I suddenly return home with a deep dream. Xiaoxuan window, dressing up. They looked at each other without words, only a thousand lines of tears. It is expected that the place where the heart is broken every year, on a bright moonlit night, there will be short pine hills. Thousands of miles away, the great poet still remembered his wife who had died ten years ago. This feeling will not fade or change with time. ...
Poetry is even more difficult!
The poet has an indissoluble bond with the moon. Among the 300 Tang poems, six are titled with the moon, including "Drinking Alone under the Moon" and "Looking at the Moon and Huaiyuan". Song lyrics also include "Moon on the West River", "Moon on the River", "Moon on the Qin Tower", etc. Of course, chanting on a moonlit night, There are countless poems that lament the past and hurt the present. We imagine that if there was no moon, how would poets feel at night? What will become of the poems about the moon by Li Bai, Su Shi, Du Mu, Li Qingzhao and others?
Appendix: The poet's top ten poems about the moon -
1. Li Bai The bright moonlight in front of the bed seems like frost on the ground; I look up at the moon and look down at my hometown. (Quiet Night Thoughts)
2. When will the bright moon of Su Shi appear? Ask the sky for wine. (Shui Tiao Song Tou)
3. Du Fu Tonight in Yanzhou, I can only watch the moon in my boudoir. I pity my children from afar, but I still remember Chang'an. (Moonlight Night)
4. Li Shangyin The candle shadow on the mica screen is deep, and the long river gradually sets and the dawn stars sink. Chang'e should regret stealing the elixir, and her heart will be filled with blue sea and blue sky every night. (Chang'e)
5. Zhang Ji The moon is setting and the sky is covered with crows and frost, the river maples and fishing fires are facing melancholy; outside the city of Suzhou, Hanshan Temple, the midnight bell is ringing for the passenger ship.
