What happens, If moon suddenly disappears?

If the moon suddenly disappears, what will happen? Would there be life on the Earth without the moon? Let’s find out the answers to these questions…

Earth’s human life will undergo tremendous changes, and some organisms will have a greater impact.

The moon suspended in the night sky not only has a beautiful face, it also helps guide the earth currents and tides, and is closely related to the earth’s atmospheric movement, climate change, and the tilt of the earth’s axis. So if the moon suddenly disappears, what will happen to the Earth? Can humans survive?

It is unlikely that humans will die due to the disappearance of the moon, but there will be some significant changes on Earth. We will immediately notice that the “night sky” is obviously darkened. The moon’s surface reflects the sun’s rays and illuminates the Earth’s night sky. Without this indirect light from the moon, it will be very inconvenient for people to walk at night when the Earth cannot obtain artificial light. For example, rural areas. Road or wooded campsite.

What happens, If moon suddenly disappears

The sudden disappearance of the moon can also be confusing to animals. A review article published in the Journal of Animal Ecology in 2013 stated that researchers have found that using the visual as an animal that interacts with the surrounding environment, the existence of the moon benefits them, shallow. This is not an amazing thing. If the moon suddenly disappears, there will be some interesting changes. Many predators, such as owls and lions, rely on the cover of darkness and can hunt only with a weak moonlight.

If the moon disappears, they are hunting at night. On the contrary, rodents that specialize in activities at night will hide when the moonlight is strong. If the moon disappears, their nighttime activities will become unbridled and their populations will increase rapidly. The first author of the study, Wildlife ecologist Laura Prug of the University of Washington, said: “I think you will find some changes in the Earth’s ecosystem.”

One more thing that has a direct impact is the tide. Because the Moon is very close to the Earth, its gravitational effect affects the Earth. The gravity of the Moon is not as strong as the gravitational force exerted by the Earth on the Moon. The Moon will orbit the Earth, but the Moon’s gravity will cause the Earth’s oceans to produce “tidal phenomena.” According to Matt Siegler, a research scientist at NASA’s Jet Propulsion Laboratory who has worked on lunar orbit surveys, if the moon disappears, the ocean tide fluctuations will be significantly slower, about one-third of the current tide fluctuations. However, the Earth’s tides will not completely disappear because the sun also generates tidal gravity on the earth’s oceans.

Less than two-thirds of the tidal effects of the ocean will directly change the marine ecosystem, potentially destroying many marine ecosystems, and disrupting the cyclical flow of energy, water, minerals, and other resources. The entire marine ecosystem is affected by high and low tides. Many marine species such as crabs, snails, barnacles, mussels, sea stars, kelp, and seaweed rely on daily changes in tides. At the same time, these “tidal creatures” are particularly important to the Earth’s ecological system. Importantly, food sources are provided for migratory organisms and local birds, and even terrestrial mammals such as bears, raccoons and deer feed on tidal organisms.

Tide movements also help drive ocean currents, and ocean currents will directly affect global climate change because ocean currents drive warm seawater circulation in the global oceans and have a significant impact on precipitation. Jack Burns, head of the survey and space science network at the University of Colorado, said that if the tide weakens by two-thirds, the regional temperature will become more extreme. At the same time, some major climate events will occur. The disappearance of the moon will not only affect the tide of the ocean. Gravity pulling on the Moon will also cause the movement of atmospheric molecules.

Because of the existence of the moon, it can stabilize the Earth’s climate. Planets with larger satellites are an important condition for scientists to identify potential life-friendly planets. Burns said: “External planets need to have a huge planet in order to keep the planet’s climate system very calm, thus helping to nurture a human civilization similar to Earth.”

The disappearance of the moon will have a more devastating effect, although this will take a long time span. If there is no lunar attraction that “fixes” the earth, the tilt of the earth axis is likely to change significantly with time. The earth may be more inclined until there are almost no seasonal changes. In just a few hundred thousand years, the earth will experience extreme seasonal weather and enter the ice age. Burns used Mars as an example to illustrate that with the significant changes in the dip angle of Mars, extreme weather phenomena will occur. The reason is that Mars does not have large stable satellites, which has a fixed effect on Mars.

From the human perspective of the earth, if there is no moon, we will lose the source of artistic inspiration and scientific information. Siegler said: “We are very fortunate that the moon is very easy to reach the destination. Its existence has always inspired people. The moon has provided us with the origin of the Earth’s revelation, the formation of other planets, and how the dinosaurs were extinguished. If the moon disappears, we will lack a large source of scientific information.”

Fortunately, so far there is no evidence that the moon suddenly disappears or will destroy itself or have a devastating collision with other orbiting celestial bodies.
