How would the world change without the moon?

The Moon is about 380,000 kilometers away from the Earth, and the Moon we see does not emit light on its own, but reflects the sun's rays. Some people may think that the moon has no practical meaning for us, but the moon has an important impact on the earth's environment, and we can think of the earth's ecosystem as shaped by the sun and the moon together. So, what would happen if the moon suddenly disappeared?

First of all, the most immediate effect is that the earth's tides will change. The current tides are mainly influenced by the gravitational pull of the Sun and the Moon, with the Moon playing a greater role. Without the moon, the tides would decrease, causing the Earth to rotate faster, and the day would be shortened to just 8 hours. This drastic change is not adaptable to humans because our biological clock is based on a 25-hour cycle. Such a change will bring great distress to our lives.

In addition to the change in rotational speed, the wind will also become a more powerful force of nature. We observed that Jupiter's surface was covered with huge horizontal streaks, which were actually giant storms. Now imagine that if the Earth's day were shortened to 8 hours, the wind would reach 100 kilometers per hour. The entire planet will be swept away by storms, mountains may disappear due to wind erosion, and oceans may flood areas close to the coast. The vast majority of species will have difficulty adapting to this new environment, and survival will be difficult.

There were people who wanted to blow up the moon, and during the Cold War between the United States and the Soviet Union in the 50s of the last century, the United States planned to use nuclear ** to conduct a test of blowing up the moon in order to surpass the Soviet Union in the nuclear race. However, there are huge risks associated with this plan, as it will produce debris and dust that will have a catastrophic impact on the planet. As a result, scientists canceled the program and launched the famous Apollo program.

In fact, although the Moon may seem small, it is not easy to completely destroy the Moon, and it cannot be achieved with existing technology. What's more, the Moon belongs to the Earth, and no individual or country has the right to destroy it. It would be a disaster if the Moon were to leave its orbit and hit the Earth. With our current state of technology, it is difficult to prevent such an event from happening. Another collision between the Moon and the Earth would return the Earth to where it was formed, making it extremely difficult for the Earth to re-evolve into life. It follows that life on Earth is unique.

The Moon is currently on the moon at an annual rate of 3The speed of 8 centimeters leaves the Earth, although it is slow and imperceptible, but at this rate, in about 5 billion years, the Moon will reach its farthest point and be attracted by the Earth's gravity again before hitting the Earth. However, by then, the Sun will also become a red giant, and the Earth's original orbit will long be gone.

Taken together, the absence of the moon will have a huge impact on the ecological environment of the earth and our lives. The moon not only gives us a beautiful night sky, but also plays an important role in the tides, climate, and more. We should cherish the moon, protect the earth, and work together to maintain a better world.
