If the sun burns out, will there still be life in the solar system?

Everything depends on the sun for its growth", and without the existence of the sun, the solar system is likely to no longer be suitable for life on earth. The evolution of the Sun as a star has a certain pattern, and it is estimated that the Sun will "burn" steadily for another 5 billion years.

The sun is a star, and stars have a lifespan, which means that when the sun runs out of fuel, it will be destroyed. The mass of the Sun is about 200 billion trillion trillion tons, so it has a stable period of about 10 billion years. According to scientists' calculations, the sun has been burning for 5 billion years and is now in its own "middle age".

For the next 5 billion years, it will continue to burn until it runs out of energy.

Because the mass of the solar nuclear fusion is constantly being lost, the gravitational force is gradually decreasing, and the imbalance of gravitational action will cause the outer gas of the sun to expand outward, and at the same time spray its own outer gas, which will affect the earth. The Earth's atmosphere will be destroyed by strong stellar storms, the surface temperature will rise dramatically, and the Earth's light conditions will also change, each of which will be a huge blow to life on Earth.

According to archaeological research and the characteristics of life in submarine hydrothermal vent life systems, it is currently believed that life on earth originated in the random collision reaction of molecules driven by continuous energy, first some simple organic matter, then complex organic matter, and by chance organic matter composed of living organisms, which can use geochemical energy to synthesize the substances they need, and then green plants appeared.

It is estimated that in the next 7 billion years, the sun will expand into a red giant more than 100 times the size of today, and the position of the earth will be within the range of stellar storms, which will evaporate all the surface water and the temperature will be extremely high, which will already lead to the extinction of all life on earth. Organisms that produce nutrients from the chemical energy released from the Earth's interior are able to resist for a relatively longer period of time, but by the time all the Earth's water evaporates, the surface temperature will also roast them to death. Sometimes when we think about it, human history is only tens of thousands of years, and an ordinary star in the Milky Way has a lifespan of 10 billion years, compared to the universe, we are still too small.

Probably not, because the earth depends on the sun to have life, and if the sun burns out, then life on the earth will not survive.

No. The energy on which life depends** is solar energy, and when the sun disappears, life lacks energy**, and it will inevitably perish.

If the sun burns out, there will still be life in the solar system. Because the sun gives heat to the earth and other planets, but there are also some microorganisms that are used to living in cold environments.

01 Life is inseparable from water, air, sunlight, suitable temperature, and nutrients necessary for life to survive. In the solar system, the Earth is at the right distance from the Sun, so the light and temperature that the Earth receives during the day and at night are suitable for life. In addition, the size and "weight" of the earth are also very suitable for survival.

In the area where the atmosphere and the sea and land come into contact with each other, there are animals, plants, and microorganisms all over the earth, which is the circle of life matter and life activities on the earth, and we call it life. The thickness of life is about 20 km.

In the solar system, there is only life on Earth, and there are no animals, no plants, or no life on the other planets.

Why is there no life on the other planets of the solar system? This starts with the conditions of life's existence.

First of all, the existence of life needs to have the right temperature. If the temperature is too high, the movement of the atoms is too strong and it is difficult to polymerize into molecules; If the temperature is too low, the proteins and nucleic acids will freeze, and life will not matter.

From a temperature point of view, the distance between the Earth and the Sun is unique. The average surface temperature of the Earth is about 22 degrees Celsius, and most of it is suitable for the growth and reproduction of life.

Among the planets of the solar system, the Earth's closest neighbors are Venus and Mars. Venus is closer to the Sun than the Earth, and its surface temperature is about 400 degrees Celsius warmer than that of the Earth; Mars is farther from the Sun than the Earth, and the temperature on the surface is 40 or 50 degrees Celsius lower than that of the Earth, and the temperature difference between day and night is large. The other planets are either closer to the Sun than Venus or farther away from the Sun than Fire, so they do not have the temperature conditions suitable for life.

Secondly, the existence of life requires the presence of liquid water, and there is a large amount of water on the earth, and the vast majority of water is liquid. And on other planets, even if there is water, it is not liquid.

In addition, the existence of life requires an atmosphere of appropriate thickness and density to protect life from cosmic rays and provide the right amount of free oxygen. The Earth's atmosphere fulfills this condition.

Other planets such as Venus, Mars, Jupiter, Uranus, Neptune, and even Saturn's sixth moon have atmospheres, but the atmospheres on these planets or moons are almost oxygen-free, so even if some form of life may occur on these planets, it can only be extremely primitive.

Based on the above analysis, such life on Earth is unique in the solar system.

However, many people believe that in the vast desert universe, there must be celestial bodies with life, and even celestial bodies with highly intelligent life like humans.
