What would happen if the Moon disappeared?

From the dawn of human civilization, our moon has held a significant status, revered and immortalized by various religions across the globe. In Greek mythology, the moon was personified as Selene, the daughter of the Titans Hyperion and Theia. Selene was worshipped and respected in the same manner as the sun god Helios, indicating that our ancestors regarded the moon and the sun as equals. Hindu mythology also worships the moon, particularly by those who experience the fluctuations of life and wish for stability, as well as those who desire to have sons.

Throughout history, the moon has captivated artists and inspired countless works of art. It is prominently featured in Van Gogh's masterpiece "The Starry Night" and celebrated in Frank Sinatra's delightful song "Fly Me to the Moon," among many other captivating creations. The moon's allure has always enchanted both art and history.

However, today we aim to shed light on the moon's crucial role in advancing our civilization from a scientific perspective. Our focus is to answer the question, "What would happen if the moon disappeared?" But before delving into that, let us explore some key facts about the moon.

1. The moon is the closest and brightest celestial object that orbits the Earth in an elliptical path. Its orbit orientation is not fixed in space but undergoes rotation over time, resulting in precession and inclination. As a result, its apparent size may differ from its actual size when observed from Earth. This phenomenon can be understood by considering that objects appear larger when they are closer to the observer.

2. The moon formed approximately 4.51 billion years ago, around 60 million years after the formation of the entire solar system. There are various models explaining the moon's formation, but the prevailing one suggests that the Earth-Moon system was created through a colossal impact between a celestial body the size of Mars, known as Theia, and the proto-Earth during its early stages.

By understanding these fundamental aspects of the moon, we can now explore the intriguing question of what would occur if the moon were to vanish.2The moon's impact on Earth's formation is undeniable, as it played a crucial role in shaping our planet and even forming the moon itself. The differentiation of the moon into crust, mantle, and core mirrors that of Earth, with each layer having its own unique characteristics. The composition of the moon's crust, rich in magnesium and iron, provides valuable insights into its geological history. The process of magma fractional crystallization that formed the moon's mantle is a complex yet essential part of understanding its structure. The solid core, surrounded by a molten iron boundary, adds to the moon's intriguing composition.The food chain is a crucial concept that illustrates the movement of energy and nutrients within an ecosystem. Energy is transferred from one organism to another through the consumption of food. Within the food chain, there are primary producers, such as plants, which serve as a food source for primary consumers, such as animals. Additionally, there are secondary consumers, including predators and decomposers.

Another significant factor in the ecosystem is moonlight. A study published in the Journal of Animal Ecology highlights the importance of moonlight. It reveals that the absence of moonlight can impact the activity of prey species that rely on vision as their primary sensory system. In contrast, prey species that utilize other sensory systems, such as olfaction or echolocation, may experience increased activity. For instance, predators like lions and owls, who rely on vision, will struggle to hunt without moonlight. However, olfactory predators like foxes, cats, and snakes can still hunt effectively. This disruption in the food chain can lead to an irreversible imbalance in the ecosystem.

Tides, on the other hand, are low-frequency waves with long periods that traverse the oceans in response to the gravitational pull exerted by the sun and the moon on the Earth. This gravitational force, known as the tidal force, causes the water in the oceans to bulge outward, resulting in areas of low and high tides.
