How old is the Earth now? How long does it have to live?

Scientists. I have conducted various studies on the earth in various ways, and I have measured the distance from the sun to the earth beforeThe lifespan of the Earth. According to the data analyzed by scientists, the lifespan of the Earth is about 9.6 billion years.

The Earth has been around for 4.6 billion years and will continue to do so for 5 billion years.

According to geologists, the Earth is at least 4.6 billion years old. However, human beings only have a few thousand years of written history, which is only a moment in the long river of the universe.

To find out the lifespan of the Earth, we must first look at the lifespan of the Sun. The Sun is the closest star to Earth and is also the solar system.

The only luminous body. It undergoes a nuclear fusion reaction.

It radiates a huge amount of energy and continuously transmits light and heat to the earth, which is the root of all life.

In the current state of the sun, we always feel like a vigorous "young man", and even think that it will always provide enough light and heat to the earth. In fact, just as people experience birth, old age, sickness and death, the sun also has its own youth, middle age and old age. It slowly decays and grows old.

After a series of expansions, **, pulsations, and finally fell silent.

It is believed that the sun is in its prime of life, and this period of stability will last for 5 billion years.

However, before the Earth is swallowed, it may have been roasted into a barren land, and all life on Earth will come to an end. Because the sun is going through thermonuclear reactions all the time.

As the Sun expands over time, it will become hotter and hotter than before, and the light and heat transferred to the Earth will become stronger and stronger. As the temperature rises, the water on the earth's surface begins to evaporate rapidly, making it no longer suitable for life.

Apart from the sun, the lifespan of the earth can also be affected by human factors and other factors. For example, human deforestation, polluting gases, polluting water resources, and even nuclear tests will hit the earth hard, so that the life span of the earth will not be 5 billion years.

If the life span of the Earth is the same as that of the Sun, then it will only be about 50 to 6 billion years, but for life on Earth, it will not necessarily be that long. Mass extinctions.

If it had begun, life on Earth would have been much smaller than about 50 to 6 billion years. It is possible that during this period of time, there will be a new round of species replacement, so the earth may continue to continue, but it will continue to produce different species, of course, it is difficult for humans to say.

The Earth is now 4.6 billion years old. It has at least 5 billion years to live, which is a long time.

The earth has been about 100 million years old, the life of the earth will be very long, but the recent shortage of natural resources, people should cherish the resources on the earth more, the formation of environmental protection habits, so that the life of the earth can become longer, we must pay strict attention to the earth's environmental protection issues, and try our best to make the earth's life continue longer.

The earth is currently 4.6 billion years old, and the life span of the earth is still very long, because many people are paying more and more attention to the environment, so the earth will definitely live a long time.

The current lifespan of the earth is 4.6 billion years old, and it is still a long lifespan, which is also unknown. If we want the planet to survive, we must protect the environment.

Humans can't survive that system. Even if the technology is at the top of its game. You can't get out of the Milky Way.

The Earth has about four or five billion years left to live.

The Earth's lifespan is about 10 billion years, and it is now about halfway over. In other words, in four or five billion years, the earth will die out, because the end of hydrogen fusion in the sun and the beginning of helium fusion, which is the sun turning into a red giant, swallowing Mercury, Venus, and the earth, and only Mars survives among the terrestrial planets.

1. The earth is a planet accumulated from the original solar nebula, and it has been more than 100 million years since then, and the sun will become a red giant star in 100 million years, and the sun after the core burns out, the gravitational loss volume will become larger to swallow the earth, so the earth will be as hot as a furnace at that time, and the descendants of human beings will have to fly to other planets to live.

2. In about 5 billion years, the hydrogen inside the sun will be almost completely depleted, and the core of the sun will collapse, causing the temperature to rise, and this process will continue until the sun begins to fuse helium into carbon, because the energy produced by helium combustion is more than that produced by hydrogen combustion, so the outer layer of the sun will expand and release a part of the outer atmosphere into space.

3. If the sun's energy is depleted, then its center will collapse. At that time, the sun will not be able to provide energy to the earth, and the earth will also be "swallowed" by the center of the sun. So from the perspective that the life of the sun affects the life of the earth, the life span of the earth is about 5 billion years.

50 to 6 billion years.

Although scientists do not have a definitive data on the study of the Earth, that is, they do not know how long the Earth lives. But we can actually give a basic explanation from the change of the sun.

The sun in the solar system is the basis for the survival of life on earth, and without the sun, life on earth is basically unviable. According to scientific records, the sun is now about 100 million years old.

In other words, the sun has passed about 100 million years, but the sun is a yellow dwarf (spectrum G2V), which is expected to have an end of life, and scientists believe that the life span of the yellow dwarf is about 10 billion years, and after about 50 to 6 billion years, the hydrogen in the sun's interior will be almost completely consumed. Life on Earth could last about 5 to 6 billion years, which means that the theoretical time of the remaining sun is much lower.

IntroductionThe gravitational pull of the Earth interacts with other objects in space, especially the Moon, which is the only natural satellite of the Earth. It takes about a few days for the Earth to revolve around the Sun. The Earth's axis of rotation is tilted relative to its orbital plane, thus producing seasons on Earth.

The gravitational interaction between the Earth and the Moon causes tides that stabilize the direction of the Earth on its axis and gradually slow down its rotation. Earth is the densest planet in the solar system and the largest and most massive of the four rocky planets. The earth is the home of human beings living together, and there is only one earth for human beings.

The lifespan of the Earth is about 9.6 billion years. Through data comparison, scientists have found that the Earth will still be suitable for human life for the next 2 billion years, a somewhat surprising result, which is fortunate for humans. There are countless possibilities in 2 billion years, and with the rapid development of science, people may find a second home in space for human beings to move to.

The history of the Earth's generationAccording to scientific records, the birth of the earth was about 4.6 billion years ago, and the original earth was different from today, and the formation of the original earth was a fiery fireball, and there was no life at all. It was during the second evolution of the earth that some primitive ecosystems were formed.

According to the history of the Earth, the inference of the continental drift hypothesis shows that in the second stage of the Earth's development, the Earth continuously released energy outward, forming large-scale water vapor, carbon dioxide and other substances, and finally evolved into the original atmosphere.
